Don’t Get Left in the Heat: Knowing Its Time For an AC Replacement

Don’t Get Left in the Heat: Knowing It’s Time For an AC Replacement

Since a home is such a large part of a family’s investment portfolio, homeowners are wise to learn about a home’s building systems and keep them maintained. For instance, homeowners should know the age of their roofing shingles, carpet, and windows, and have a general idea of how soon they will need to be replaced. Another important building system to investigate is the air conditioning system.

Air conditioners are complex electro-mechanical systems, with four major functions:

Air conditioners cool the indoor space, making it comfortable and healthy for human habitation
Air conditioners remove excess humidity from the air for comfort and health
Air conditioners have a filtration system and clean the air with every cooling cycle
Air conditioners move air to ensure every area of the home is receiving fresh air

Homes are very difficult to maintain as abodes in South Texas without air conditioning. Knowing when to repair and when to replace an air conditioning system is part of wise homeownership. Here are some basic tips about air conditioners to help homeowners with decisions concerning replacement at just the right time.

Know When You Need an AC Replacement

Knowing the age of the air conditioner is an important first step. If you were not the owner during the last AC replacement, find the information on the model number plate. The manufacturer’s website can tell when the unit was built. Quality air conditioning systems will last between 15 and 20 years. Annual maintenance and regular air filter changes may add a few years. If your AC system is older than this, make plans for replacement soon. The goal might be to nurse it along for as long as possible, but an emergency replacement can be expensive and very inconvenient compared to a planned replacement.

Know Why You Need an AC Replacement

Like any system in use, the parts eventually begin to show signs of wear. There are a few moving parts in an AC system. Two motors turn fans that assist with heat transfer, one inside the air handler cabinet and one outside in the condenser unit. It is easy to understand wear and tear on moving parts. But wear and tear also happen to electrical parts—switches, sensors, and control units.
Wear will lead to repair visits to replace certain failing parts. Eventually, a large enough component will fail so that the repair cost rivals the cost of replacing a system. Keep a tally of repair costs and make sure that the cumulative costs of repairs do not climb too high.
Perhaps the first indication of a problem is that the air conditioner is beginning to perform poorly. The air coming through the vents might be warm, not cold. The air conditioner might struggle to keep up during prolonged heat waves, forcing longer-than-normal cooling cycles. Certain rooms or spaces might never seem to get cool. The relative humidity indoors is very similar to outdoor humidity. There might be a simple solution, like a clogged air filter. If not, the solution might be attributed to a weakened air conditioner system.
The clues might come from annoying smells or loud noises. The smells might seem sour or mildewy. The sounds might be loud, banging, or buzzing. They will not go away on their own and are often indications of a rapidly failing system.

Clear indications of an imminent catastrophic failure often include most or all of these signs–an aged air conditioning system that performs poorly, is expensive to keep running because it keeps making noises and smells foul. A wise homeowner will begin making plans for an AC replacement as soon as these signs begin to appear.

AC Maintenance for Katy Texas Homes

Ensure Comfort All Summer: Katy Texas AC Maintenance Checklist

Spring days, with mild temperatures during the day and cool temperatures during the evening, are in the rear-view mirror. It will be a while before opening windows for long periods of time happens in Katy Texas. Accompanying the hotter temperatures will be higher humidity and high pollen count, so keeping the air conditioner performing well all summer is essential for comfortable summer living. Performance and consistency over the long run depend upon a great preventative AC maintenance plan. Do you have a great AC maintenance plan in place?

Scheduling Professional AC Maintenance

There are plenty of steps a homeowner can take to care for an air conditioner system, but there are some steps that need to be handled by a trained HVAC professional.

Anyone who handles the refrigerant gases used for air conditioning and refrigeration must complete U.S. Environmental Protection Agency training and be certified. That is a lot more work than most homeowners are willing to take on.
The air conditioner’s electronics are complex and must be handled with training and on-the-job training; some wires carry 220V and some carry 24V. It is important to know the difference between the two, since one can give a deadly shock.
Heating and air conditioning are processes. Knowing the processes is essential to knowing how to properly maintain the system.
When repairs need to be completed, it is important to know someone who can diagnose the problem and make the repairs.

Schedule Filter Changes

The entire volume of a home’s air passes the air filter 3 or 5 times per cooling cycle. The purpose of the filter is to remove airborne contaminants, and they do a superb job. Since they are so effective, they need to be changed often.

A dirty, clogged filter restricts the amount of air that can flow through the filter, and the air conditioner function requires a massive amount of airflow. A dirty filter prevents your air conditioner from cooling your home (and your furnace from heating your home).
The air filter is located close to the evaporator chamber, the area where humidity is removed from the home’s air. A dirty filter often results in higher humidity inside the home.
For most homes, changing the air filter every three months is the recommended procedure. If your home has extenuating circumstances that require a more frequent filter change—a dirt road or a nearby construction site—you will be in a position to know and make more frequent changes.
Locate the air filter at the base of the air handler closet, where the ductwork brings air from the home to the cabinet. Air filters are available at most hardware and do-it-yourself home improvement stores.

Clean the Condenser Unit

The outdoor portion of the air conditioner is called a condenser unit, and it also acts like a filter.

The walls of the condenser unit are a network of tubes and fins, containing hot refrigerant gas during cooling cycles. A large fan in the hollow center draws air through the network to cool the gas, but it also draws dirt, sticky pollen, and lawn debris, like grass clippings. The collection hinders the free flow of air through the condenser and needs to be cleaned away.
Before trying to clean the condenser, trip the breaker for the air conditioner. The condenser covers are attached with a few metal screws on each side. After removing the cover, use a garden hose to gently wash away the debris and dirt. Replace the covers and flip the breaker back to the ON position.
Make sure to trim shrubs and tall, ornamental grass at least 2 feet away from the condenser unit.

Is Your AC Sick? 9 Signs You Need AC Repair

Avoid the Heat: Know When to Call for AC Repair

Is your air conditioner functioning properly? How can you tell whether you need to repair the air conditioner? Here are some common signs that indicate repairs are in order.

1 High Humidity

When the relative humidity indoors matches the outdoor air, it indicates that the air conditioner is not removing moisture properly. Solid surfaces on furniture, flooring, and walls may feel sticky since the finishes are collecting moisture. Skin may also feel sticky, but it may not be from sweat.

2 High Temperature

Since air conditioning removes both humidity and heat from indoor spaces, whenever the indoor temperature rises, it usually indicates that the air conditioning function is failing. (If the temperature is very high, an old system may struggle to keep up without indicating failure.) Observe the thermostat setting and the actual temperature indicated to determine the depth of the problem.

3 Hot Spots

If the main spaces of the home are cool, but upper-story spaces or rooms far from the air handler cabinet are hotter than normal, it indicates the need for AC repair. This is especially true if these hot spots are a new development.

4 Low Airflow

If the amount of cool air flowing from the supply vents has declined substantially in the recent past, this indicates the need for AC repair. This low airflow may result in high humidity, high temperatures,

and spaces that are not receiving sufficient cool air.

5 Strange Noises

Usually, air conditioner noises are limited to those associated with a blower motor and the gentle movement of air through supply vents. However, when the blower motor or other air conditioner components begin making loud, irritating noises, such as grinding, screeching, or banging noises, it indicates that the blower motor needs to be repaired. If electrical controls emit loud buzzing or rapid clicking noises, it indicates that AC repair is necessary.

6 Obnoxious Smells

The air conditioner should be moving the available air within the home. When the air exiting the supply vents smells unhealthy, it indicates that something is wrong and needs to be repaired. Healthy indoor air is essential to keep a family safe and healthy.

7 Water or Ice

Anytime ice build-up is observed on any part of the air conditioner components, whether indoors or outdoors, it is a serious problem that requires serious repair. Ice on the coils of the outdoor condenser unit is generally easily observed. However, ice build-up indoors may happen behind the walls of the air handler cabinet. What may be observed more quickly is the water leaking from the cabinet as the ice melts. Ice on the components or water leaking from any components (except through the drain lines) indicates the need for AC repair.

8 Long Cooling Cycles

If the air conditioner cooling cycles are exceptionally long or the air conditioner does not turn off, it indicates a serious problem. Of course, cooling cycles during periods of extreme heat might be normal. However, long cooling cycles during normal heat are problematic.

9 High Energy Bills

The price of energy fluctuates a bit, but if the electricity bill continually rises over the cooling season, it bears further investigation. Do a little research to determine whether the energy required for cooling (measured in kWhs) has increased during this month compared to last year or the year prior.

Components that are failing require more energy to accomplish the required tasks. Increased energy use without the addition of other devices generally indicates the need for AC repair.

Keep Cool and Save Money: Call All Cool for AC Repair

These indicators may happen individually, or several of these indicators may happen at once. If you observe these signs, call your AllCool AC and Heating AC repair technician and schedule an appointment.

Texas Summer Survival: Indoor Air Quality

Winning the Humidity War: Your AC’s Crucial Role in Indoor Air Quality

The effects of air conditioning on the air temperature and indoor air quality is very evident, but did you know that air conditioning also dehumidifies summertime air? The official name for your system is the heating, ventilation, and air conditioning system, or HVAC. Air conditioning and ventilation work together to remove moisture from the air and keep the home comfortable and SAFE.

Why Does My House Feel Sticky? The Role of AC in Dehumidification

Is high humidity indoors dangerous? Visit abandoned spaces without HVAC, and you will discover musty places with mold and mildew growing. Paint and stains bubble up from surfaces and get very tacky to the touch. These spaces are considered unhealthy and unsafe for human habitation. This is the difference that an HVAC system makes in indoor spaces. High humidity reduces indoor air quality and can also represent a major health risk for family members who suffer from allergies, asthma, and breathing difficulties that are exacerbated by the presence of mold or mildew spores.

The target range of indoor humidity is between 30% and 50%, with 40% recognized as the most comfortable target humidity. Lower humidity can cause woodwork to crack, skin to get dry, and nasal passages to get dry as well. Higher humidity results in furniture, walls, and flooring surfaces feeling slightly wet or sticky, and human skin also being moist and sweaty.

High humidity can also foster mold and mildew growth. The spores surround us and may also be found in the soil of indoor plants. Moist, dark surfaces promote mold blooms; that is exactly the environment created after a shower, bath, or other cleaning activities. The air conditioning and ventilation system components remove the airborne spores and reduce the moisture content from the air, making it healthier.

The major source of indoor humidity is outdoor humidity, and South Texas experiences high humidity during the entire cooling season. It is not uncommon to experience outdoor relative humidity above 90% in our area during the late summer. Indoor sources also abound, including bathing, cooking, and cleaning activities add moisture to the air. Human, pet, and even plant respiration add to indoor moisture content.

What can be done to combat high humidity indoors and improve indoor air quality?

Fix water leaks, since they are often out of sight, yet they contribute to the humidity/mold problem.
Keep your air conditioner well-maintained. An annual inspection and cleaning will remove dust particles that cling to surfaces and inhibit cooling and dehumidification.
Change your air filter regularly, at least once every three months. A dirty filter can inhibit the airflow into the evaporator chamber, the center for humidity removal.
Be aware of water that might leak from the air handler cabinet. It may be the result of a clogged drain line, but the evaporator coil is removing several gallons of water per day from the air. If the drain line is clogged, this water will migrate, potentially ruining flooring, furniture, and other surfaces. The leaking water can also be an indicator of bigger problems. Either way, do not ignore an air conditioner water leak.
If indoor humidity seems to be a big problem, use exhaust fans during showers and cooking. This limits the amount of moisture from these sources. Find good times to open windows or a door to increase ventilation. Make sure that the outdoor temperature and relative humidity are lower than the desired indoor temperature and humidity.
If air conditioning and ventilation are not enough, consider a residential dehumidifier. These devices are rather small but are effective at removing water from the air. Be sure to empty the collection basin and keep the unit clean and free from dust and spores.

Breathe Easier with All Cool AC: Simple Steps to Improve Your Indoor Air Quality and Reduce Indoor Humidity

Air conditioning plays a crucial role in dehumidifying indoor air, especially in humid climates like South Texas, thus significantly impacting indoor air quality. High indoor humidity can lead to mold growth, exacerbate respiratory issues, and create uncomfortable living conditions.

Spring AC Maintenance Checklist

Essential Spring AC Maintenance Tips

Springtime is an important time for air conditioning system maintenance.

The furnace equipment is now dormant until it is called up in late fall, that is, unless your system uses a heat pump. Heat pumps use the same equipment for heating and cooling.
During the early spring, the temperatures are mild, so air conditioning equipment is relatively idle, an ideal time for air conditioning maintenance.
When the temperatures begin to soar, the calls for repairs and replacement of air conditioning systems rise as well. Springtime is an ideal time for scheduling a maintenance call with your HVAC professional.

In the meantime, here are some maintenance steps you can take on your own.

Change the Air Filter

Pollen is at its highest during the early spring; trees, flowers, flowering trees, and grass are all releasing pollen at the same time. The pollen count is enough to trigger sinus problems with or without allergies. A springtime air filter change can help everyone breathe easier. The filter should be changed at least every three months, more frequently if necessary.

Air filters work tirelessly to clean the air, removing pollen, dust, dander, and more. However, when the trapped particles completely cover the filter, it begins to restrict proper airflow. The very best air conditioning technology cannot function properly without adequate airflow.

Clean the Condenser

The outdoor portion of the air conditioner is called the condenser unit. The walls appear to be solid, but the walls are actually a network of tubes, designed to allow considerable airflow between. A central fan pulls air through the tubes, but it also pulls pollen, dust, and all kinds of debris. Pollen is sticky. It sticks to the tubes and fins, and the pollen tends to collect anything other small particles it encounters.

Cleaning the pollen and debris from the condenser is an easy DIY project. Remove the screws around the cover of the condenser and use a garden hose to gently wash away the collected particles. Wash the tubes until the water flows clear, then replace the covers.

Should the pollen and dust continue to coat the condenser, this makes the air conditioner work MUCH harder and it can lead to some serious repair bills. This is a simple task that can be completed with a few tools and a little bit of time.

Change Batteries

The thermostat is the ON/OFF switch for your air conditioner. It is a very small computer with sensors and switches that control a whole, complicated building system. This small computer is powered by common household batteries, and the batteries need to be changed. Matter of fact, there are several small sensors/switches in the home that run on batteries, including smoke alarms and carbon monoxide detectors. Find a time in the spring and change all of your batteries at once.

Schedule Professional AC Maintenance

These are DIY tasks that can be completed by a homeowner. There are plenty of air conditioner maintenance tasks that need to be completed but cannot be completed by a homeowner. They take special equipment and the training to use it properly. Professional technicians test and clean:

The refrigerant level
Electrical controls and switches, some with high-voltage
Functional performance of the air conditioner

Springtime is an excellent time to schedule AC maintenance.

Homeowner’s Guide to Indoor Air Quality

Allergy Relief: Tips for a Better Indoor Air Quality and a Pollen-Free Home

Allergy sufferers know what time of year this is. It is allergy season! For the next few months, trees, grasses, and wildflowers will take their turn releasing pollen into the air. On some mornings, you can expect to see the ground covered with pollen. Spring rains will also result in mold blooms if that is your allergy trigger.

It would be nice to escape the high pollen/mold count by going inside like one might find relief from the summer heat. However, the American Lung Association finds that indoor spaces usually have 2 to 5 times the airborne particles found outdoors. Reducing the quantity of indoor contaminants, including pollen and mold spores, will be accomplished by very intentional steps. Here are several precautions one might take to improve indoor air quality during the pollen season.

Stop in Your Tracks. Anyone entering space during this season is bringing pollen and spores with them and transporting them around the house; shoes and coats pick up a healthy supply. Make it a habit of removing shoes and jackets immediately to avoid carrying pollen any further than necessary.
Leave the HVAC fan running 24/7. The cost of operating the fan like this is a fraction of the cost of heating or cooling. The fan collects the entire volume of the home and passes it through an air filter; this happens about every two minutes. The air filter will pick up most pollen and trap it. However, this may require that the air filter be changed more frequently than normal. A clogged air filter will reduce efficiency and prevent the air conditioner from functioning properly.
Cleaning is Essential. Pollen and mold spores are light, but they are heavier than air. When the air is still, particles will settle out of the air and will land on every surface. Dusting, vacuuming, and mopping help to remove these particles forever from your home. Since people spend 8 hours per day sleeping, make sure to change the bedding often.
Open a Window. While the temperatures are mild, turn off the air conditioner and open the window for a few hours. This helps to dilute the level of contamination in indoor spaces. Remember, the outdoor air tends to be cleaner than the indoor air. Make sure to choose a time without high winds, since pollen readily travels on the wind.
Be Aware of Indoor Sources. Some homes have sources of pollen and mold spores hiding in plain sight. Indoor plants may have mold-laden soil, and any blooms may contribute to the pollen count. Pets may also carry pollen/mold; their bedding will need to be cleaned often during this time.

If any family member in your home has allergies or asthma which is severely triggered by pollen or mold spores, you may consider additional technology to clean the home’s air.

Consult with your HVAC professional concerning adding ultraviolet lights inside the ductwork. The light energy disrupts the cell walls of living pollen or mold (along with bacteria, viruses, and dust mites). The inert particles lose their allergenic properties and can be captured or cleaned away easily.
Family members with severe breathing difficulties may benefit from a whole-house or room air purifier. These devices have multiple layers of filtration and clean the air more thoroughly.

Survive Allergy Season: Improve Indoor Air Quality with the Help of All Cool AC & Heating

Despite the outdoor pollen surge, indoor air quality can be significantly more polluted, exacerbating allergy symptoms. These practical tips like removing outdoor clothing upon entry, maintaining constant HVAC fan operation with clean filters, and frequent cleaning to minimize indoor allergens can help allergy sufferers.

For severe cases, we recommend consulting our indoor air quality HVAC professionals about UV lights and considering air purifiers to enhance indoor air quality.

Spring HVAC Maintenance Tips

Spring into Comfort: Spring HVAC Maintenance

YeeHaw! Spring is almost here! With the end of winter days away, this is the perfect time to schedule a preventative HVAC maintenance visit for your heating, ventilation, and AIR CONDITIONING (HVAC) system. In a few months, the heat will arrive in earnest and keep technicians busy through the long cooling season. The lull in activity between the heating and cooling seasons is perfect for such tasks.

While the HVAC maintenance technician will complete several tasks that require specialized training and equipment, there are several tasks that diligent homeowners can complete to improve efficiency, longevity, and comfort. Here are a few HVAC maintenance steps that homeowners can take to prepare the system for spring and summer.

Take Care of Vents

A network of pipes (ducts) transports air from the house to the air handler and from the air handler to the house. The pipes are called ducts, and the openings inside the house are called vents.

Anything that covers the vents interferes with the free flow of air. The air conditioner, or furnace, depending on the season, requires sufficient airflow; if clothing, furniture, or drapes cover the vent(s), it impedes the adequate flow of air.
The massive amount of air that moves through the ductwork also carries plenty of airborne particles. Over time, some of these particles are collected by the air filter and some are left behind. It is recommended that the ductwork be cleaned every 3 to 5 years, depending on the local environment.

Keep an HVAC Maintenance Schedule

There are certain things that homeowners need to remember to do regularly. Neglecting these routine tasks can have deleterious consequences. To avoid harm to the HVAC system or the home, there are a few things that deserve a calendar prompt to remind homeowners to complete the tasks. Those tasks would include:

Changing the air filter quarterly. With each heating or cooling cycle, the filter faithfully removes airborne particles on the filter surface. When the collection begins to restrict airflow, it reduces comfort and forces the system to work harder. Use a holiday or a seasonal reminder, use a calendar or a phone prompt, but don’t forget.
Several home devices are powered by simple AA or AAA batteries; the thermostat, carbon monoxide detector, and all the smoke detectors throughout the home are battery-powered. Safety agencies recommend using a major holiday as an annual prompt—Memorial Day or Labor Day, for instance.

Clear the Condenser

During the preventative maintenance visit, the technician should clean the outdoor condenser unit. However, the homeowner should take careful pains to keep the condenser clean.

The condenser is responsible for transferring heat from inside to outside. Should dust, pollen or grass clippings collect on the condenser surface, it will impede the heat transfer. Cleaning it away, perhaps twice annually, will assist the air conditioner (and heat pump). Use a garden hose, no power washer, since the pressure of the power washer can damage the condenser fins.
The mower outlet should always pass away from the condenser for several passes to avoid blowing clippings directly onto the condenser surface.
For best results, the condenser needs two feet in every direction. Be sure to trim shrubs and grass away from the condenser and clean up leaves and debris.

Get Your HVAC Ready for Summer: Essential Spring HVAC Maintenance Tips

By addressing these simple yet crucial HVAC maintenance tasks, homeowners can significantly enhance their system’s efficiency and longevity, ensuring a comfortable and worry-free summer. From clearing vents and adhering to a regular filter replacement schedule to maintaining a clean condenser, these steps contribute to optimal performance and reduced energy consumption. Embracing these preventative measures not only safeguards your investment but also guarantees a cooler, more enjoyable home during the sweltering months ahead.

Beyond Programmable: Unleashing the Power of Smart Thermostats

Smart Thermostats: Your Home’s New Temperature Intelligence

One of the most significant recent innovations in HVAC technology has been the Smart thermostat.

Analog versions of this combination sensor and ON/OFF switch were relatively simple mechanical devices; analog thermostats are often round features with a moveable dial. A thin piece of metal contracted or expanded according to the indoor temperature, making contact and completing a circuit. Whenever the circuit was completed, the HVAC system responded with a heating or cooling cycle. The movement of the metal broke the circuit to end the cycle.

The next iteration replaced the mechanical components with a rather simple computer and electronic temperature sensor. With a little computer power, these versions accommodated the ability to program temperature changes. The benefits of having a programmable thermostat became very evident.

Families could adjust the temperature for comfort. It became possible to sleep in a cool room but wake to a warm space by programming the temperature changes ahead of time.
Families could adjust the temperature to save energy/money. Reducing the need for HVAC cycles while the home is empty during weekdays actually resulted in energy savings.

Few homes still have analog thermostats, but most will have a form of programmable thermostat. However, many homeowners have not taken the time to program their programmable thermostat, and it functions as a simple ON/OFF switch.

Smart thermostats add significantly more computer power and capabilities. For families seeking an integrated smart home, a smart thermostat is essential. They also:

Take temperature setting programming up several levels. They can learn from family activities and predict the need for temperature changes, even sensing additional occupants and adjusting the temperature based on room usage.
Many are compatible with voice control devices, such as Amazon Alexa or Google Assistant. Now, changing the temperature setting is a voice command away.
Smart thermostats also have a cellphone app, allowing homeowners to make temperature changes on the fly. Did someone get off work or out of school early? There is no need to come home to an uncomfortable home; the smart thermostat can prepare the settings for unexpected schedule changes.
Smart thermostats have remarkable monitoring capabilities. Diligent homeowners can be very attuned to energy usage and efficiency, gathering billing data before it is communicated by the utility company. This is useful when energy usage suddenly spikes, indicating something is dreadfully wrong. It is also useful when an aging HVAC’s gradual loss of efficiency reaches an efficiency threshold and needs to be replaced.
Smart thermostat monitoring will also remind homeowners to schedule annual maintenance and to change the air filter. These reminders make the system more efficient, reduce the repairs needed, and prolong the usefulness of the system.
Some smart thermostats can also monitor air quality, warning of various problems that develop to reduce indoor air quality.

Programmable thermostats usually come as a feature of a new HVAC system with no additional cost. Smart thermostats may cost a little as an add-on feature or be offered by utility companies. Smart thermostats require a little attention and a learning curve, as one would expect from a new program or application. They are extremely adaptable, with new features being added all the time. If you have a smart thermostat, take the time to learn the program and understand the monitoring features. This will enhance your enjoyment of your HVAC system and increase the family’s comfort.

Time for a New HVAC? Planning for HVAC Replacement

Avoid a Breakdown: Plan Your HVAC Replacement

Renovations and updates can be very rewarding and rather fun (or very frustrating, depending on your POV). A new coat of paint, new bathroom fixtures, or a transformed kitchen often adds value to a home while enhancing family enjoyment. The decision-making can be exhilarating, and the results can be quite pleasant.

However, not all home updates inspire creative juices or bring such joy. Most homeowners don’t get very excited about replacing the home’s heating, ventilation, and air conditioning (HVAC) system. Yes, replacing the HVAC system will affect the comfort and health of your family for the next 20 years and will definitely reduce heating and cooling costs, so it’s not uncomfortable. But there is nothing to see and therefore it does not elicit much excitement.

Some other benefits of a new HVAC system include:

Expect a new system to be quieter.
New systems will have variable-speed compressors and blower motors since heating/cooling needs vary when the indoor/outdoor temperature difference is slight or extreme.
New systems can have improved filtration or UV lights in the ductwork to improve indoor air quality.
New systems are usually more environmentally friendly.

Determining When It Is Time for an HVAC Replacement

Deciding the best time to replace your HVAC system will take the pressure off such a large purchase.

You should determine:

The age of your current HVAC system. Experience shows these systems last, on the short side about 15 years and on the long side about 25 years. Knowing the age of your system can help you determine when it needs to be replaced. If uncertain, collect the model/serial number from the manufacturer’s plate and take it to the brand’s website.
If replacement is overdue, replacement plans should get underway. Putting a decision off too long might result in a catastrophic failure and an emergency replacement.
If research reveals the system might have a few more years, adjust the budget now if possible, preparation for a replacement might be in order.

Other HVAC Replacement Factors

Beyond age, several other features of older HVAC systems can be detected as indications of systemic degradation.

Outdated Refrigerant. Air conditioners and heat pumps use refrigerant gas to transfer heat in and out of the home. (Refrigerant is commonly called Freon.) The US Environmental Protection Agency is constantly researching better refrigerant gas to protect the Earth’s ozone layer. Outdated refrigerants are regularly replaced with improved versions. Recently banned refrigerants include R-22, R-404a, and R-410a. If your system uses these gases, it may be impossible. If replacement is an option, the cost of replacement can be prohibited. The serial/model number plate will help a homeowner determine the type of refrigerant used.
Small repairs are not uncommon. However, some components are worn and used constantly. While they can be replaced the cost of equipment and installation rivals the cost of complete replacement. For natural gas furnaces, damage to the burner assembly/heat exchanger combination can be an expensive repair. Replacing the compressor on an air conditioner can also be very expensive. Compare the cost of new equipment with the cost of new components before making a decision.
Poor Performance. If adjusting the temperature setting does not result in a comfortable room temperature, it might indicate a minor repair is needed. Or it might indicate the entire system is extremely worn and needs to be replaced. This condition often results in higher energy use (read “high energy bills) at the same time.

While home renovations often focus on visible upgrades, replacing an HVAC system is a crucial, though less glamorous, improvement that impacts comfort, health, and energy efficiency. Knowing the age of your system is key, as most last between 15-25 years, and planning for replacement before a complete failure can prevent emergencies. Beyond age, consider factors like outdated refrigerant, costly component repairs, and declining performance when deciding if it’s time for a new HVAC system.

Improving Sugar Land Indoor Air Quality Year-Round

Improving Sugar Land Indoor Air Quality (IAQ) Year-Round: Tips for Winter and Summer Contaminants and HVAC Maintenance

According to the US Environmental Protection Agency, Americans spend 90% of their day indoors; during times of extreme temperature—summer heat and winter cold—this percentage increases. This happens because indoor spaces are conditioned to make us more comfortable. But, since the indoor air is continuously recirculating, the air must be as clean as possible. Also, the problems with Sugar Land Indoor Air Quality (IAQ) differ between the summer and the winter.

Year-Round Sugar Land Indoor Air Quality Problems

Some airborne contaminants will be prevalent year-round and need to be addressed.

Dust and Dander. Dust is a general term for almost any airborne particle, but indoor dust consists mostly of dead human skin and hair cells that flake off. Dander consists of the same skin and hair cells that flake away from indoor pets. Other dust components include fibers and chemicals from household belongings and outdoor air.

Microscopic insects also ride along and consume organic dust particles; they are called dust mites. When a family member is diagnosed with “dust allergies,” it is often an allergy to these tiny creatures and their byproducts.

Volatile organic compounds, or VOC, are gaseous compounds released from many manufactured products. The gas is released from carpets, furniture, finishes, and adhesives. The “new car smell” is actually a recognizable VOC. Most VOCs are released shortly after the manufacturing process, but trace amounts will be off-gassed continuously.

These airborne contaminants can be dealt with by very common and practical solutions.

Dust and dander are heavier than air. When the air is moving, the particles move throughout the space, but when the air is still, gravity takes over, and these particles fall to any surface underneath. A thorough cleaning (dusting, mopping, and vacuuming) removes most of these particles. Don’t forget to occasionally clean linens and drapes, since they collect dust like any other surface.
The air filter is key for removing dust and dander. More on this later.
Find a day with mild temperatures and turn off the furnace for a couple of hours. Open a few windows and doors to release the indoor air and bring in fresh air. The ventilation helps to dilute the amount of dust and VOCs trapped indoors.

Winter Sugar Land Indoor Air Quality Contaminants

A higher risk for some contaminants happens as well.

As odd as it sounds, there is a greater potential for exhaust inside during the winter. Even though there is no obvious advantage to doing so, many car owners run their vehicles during the winter to “warm it up.” If done inside the garage, even with the garage doors up, the exhaust will enter the home. Each year, the preventative maintenance check will also closely examine the burner assembly and heat exchanger to ensure the exhaust from natural gas does not make its way into the home.
While there is no pollen during the winter, the ground is wetter, and mold spores can be a problem. Mold needs moist, dark spaces to grow, and the mold spores are easily tracked into the home. Spores can trigger allergies and asthma, but they can also trigger mold blooms inside the home.

Solutions for Sugar Land Indoor Air Quality contaminants include:

Pulling a car out of the garage immediately and, if you feel the need to warm up a car, make sure to do it outdoors with the garage door closed.
Using walk-off mats at entry doors to collect dirt and spores before they are spread throughout the home.
Considering dropping shoes off at entry doors.

Role of HVAC Systems in Sugar Land Indoor Air Quality

HVAC systems use an air filter to scrub the air. With every heating or cooling cycle, a fiber filter removes a larger percentage of particulate matter from the air. However, the collection of dust can restrict air from moving through the system to heat or cool the air.
Be sure to service your HVAC system each year. The protections and benefits are important to indoor air quality.
Dust also collects in the ductwork and needs to be cleaned occasionally; cleaning the ducts every 3 to 5 years is the recommendation.
