HVAC System: Top 5 Causes of HVAC Failure

HVAC System

HVAC System Tips for Optimal Efficiency

Your home’s HVAC system is composed of several mechanical components working together, designed to keep your home safe and comfortable. It provides adequate ventilation, clean air and regulates temperature throughout your living space.

When each component functions properly you barely notice, but when something is wrong, everyone knows.

When your system fails you are aware of the discomfort because of seasonal temperatures. However, malfunctioning heating and air conditioning can also lower indoor air quality, affect health and raise energy costs unnecessarily. If your system fails, check these five things before you call an HVAC professional.

The Top 5 Causes of HVAC Failure

Check the Electrical Breaker

If the HVAC system will not work at all, go to the electrical panel and check for a tripped breaker. The panel door depicts which breaker supplies the HVAC system—usually, more than one breaker supplies the system. If the breaker is tripped, it is in a neutral position.

If you wiggle it gently, it will move both right and left. Turn the breaker off and then turn it to the “on” position. In both the on and off position the breaker will be firm, with no more wiggle.

If this is the only problem, the breaker will restore power to your system and it will return to normal use. The breaker might have tripped for a number of reasons. If the breaker trips again, contact a professional electrician to investigate the problem. It is no longer a DIY project.

Dirty Air Filters

The easiest DIY preventative maintenance task you can do for your system is to change the air filter. The filter will be positioned for easy accessibility and collects dust and pollutants before the air is heated or cooled. This keeps dust out of vital mechanical components and traps them before they can be redistributed.

An air filter will continue to collect pollutants even when it is dirty; however, the dust and pollen build up over time and slows the airflow, which and makes the blower motor work much harder. Plan on changing your filter at least every 3 months, but be aware that your home may require more frequent changes.

Factors such as living on a dusty road, near construction or having several pets might necessitate frequent filter changes.

Filters are readily available at hardware and DIY centers. Air filters come in a variety of materials, including washable filters for reuse. Explore your options.

Impeded Air Flow

The duct system transports clean conditioned air throughout the home, unless something is blocking the airflow. Occasionally a homeowner will not notice a room vent and place furniture or accessories on the vent, blocking airflow. Also, check the dampers on the room vents to ensure they are in the open position.

Your ductwork system may also have dampers in the main supply lines which regulate airflow. These dampers are designed to balance the flow of air for seasonal changes. If dampers are not balanced properly, you will experience uneven heat or AC in some rooms, while proper dampening will heat and cool rooms evenly. Uneven heating and cooling adds stress to your HVAC system and shortens system life.

Check the Thermostat

Thermostats are equivalent to an on/off switch, determined by air temperature in a room, typically the most used room in the house. If the switch is not functioning properly the entire system will not work properly.

Fortunately, replacing a thermostat is a simple and relatively inexpensive fix. Unfortunately, many homeowners are not prepared to diagnosis the problem.

If you suspect the thermostat might be the culprit, consult your professional for an inspection. In many cases, a new programmable or smart thermostat will help lower your utility bills and increase your comfort.

A Refrigerant Leak

When the outside temperature rises and your AC “can’t keep up,” it is definitely time to call your HVAC professional and have the refrigerant level checked. Your AC unit requires a gas coolant in a contained circuit and any crack or flaw in the circuit will allow the gas to escape.

Often the refrigerant escapes gradually resulting in decreasing performance and leading to a failure to cool. The decrease in performance is serious, as it causes the AC components to work extremely hard and leads to complete failure.

The HVAC professional might be able to find the source of the leak and replace the refrigerant. Replacing the refrigerant often makes an immediate, noticeable change.

4 Reasons to Get Your HVAC System Cleaned

HVAC System: Four Reasons to Hire a Professional

Having your HVAC system cleaned can be one of the most beneficial preventative maintenance functions you can do for your families’ health. Contaminants in the ventilation system can produce awful smells, high humidity, and stuffy air. Poor indoor air quality affects every breath and can lead to eye, nose, and throat irritation, headaches, allergies, and illness.

Many homeowners might consider cleaning the HVAC system a DIY project; after all, is it too difficult to clean your own home? Here are four important reasons to consider having an HVAC professional clean your ventilation system.

  1. The Right Person with the Right Tools

Cleaning the system would begin with locating all of the system parts: return vents, filter, blowers, heat exchanger/cooling coil, and supply ducts. Most homeowners would have difficulty identifying these parts, much less reaching them. An HVAC professional has the specialized equipment needed to properly clean the entire system. Having good tools is not the same as having the right tools!

  1. Dust is more than an annoyance

The average household produces 40 lbs. of dust annually, so it is more than what you see on the coffee table. Dust is produced by scratching dry skin, using a paper towel, or simply walking across the carpet. Pets, pollen, and outdoor pollutants also contribute to dust. Since the indoor air volume circulates at least 5 to 7 times daily, family members come into contact with household dust more often than you think. It can get worse. Dust might not be the worst of it: the ducts may also contain the mold in areas with high humidity or become a haven for pests.

  1. Improved system efficiency

We all know that changing air filter frequency will improve system efficiency, but heavy dust in the rest of the ventilation system will also reduce airflow. Dust builds up, clumps up, and clogs ducts, vents, and returns. Heating and cooling depend upon rapid airflow, but if dust prevents airflow the system cannot do its job effectively. This causes your system to work harder. It can also create hot and cold spots or areas of high humidity.

  1. Prolong the life of your system

Your HVAC system consists of both a heating and cooling system: dust is harmful to both. Clogged ducts and vents will add strain to the system and makes the system “feel” like it is not working properly. The prolonged strain will shorten the life of the system’s parts. In addition, if dust collects on moving parts, on electrical connections, and on bearing surfaces, it will lead to component failure.

HVAC Winter Preparation: 4 Tips to Get Ready for Winter

HVAC Winter Preparation

HVAC Winter Preparation Tips

To prepare your home’s HVAC for the Winter season, you will want to perform these preventative maintenance steps to be ready for falling temperatures.  This HVAC winter preparation checklist will help you keep your energy expenses down and make winter a whole lot more comfortable for you and your family.

HVAC Winter Preparation Checklist:

Replace HVAC System Filters

Regular replacement of the air filter is one of the most productive and easiest ways to keep your HVAC system running at its finest. Follow the manufacturer’s guidelines on which filter to use and replace it more frequently if you have chronic allergies, are a pet owner, have small children, or have a compromised immune system.

Clean Registers and Air Return Grills

Vacuum or wipe clean your registers or air return grills to keep any build-up of debris and dust from restricting airflow. Keep furniture or household decorations free from blocking these registers and to allow proper airflow.

Conduct a Heating System HVAC Winter Preparation Test

Allow your thermostat to cycle your heater on and calculate how long it takes your room to reach the set temperature. If your furnace does not come on, or it takes an extended length of time to reach the set temperature, it is time to contact us for a service call. You will want to avoid a complete system breakdown in the dead of winter.

Regularly Scheduled Maintenance Should Be part of Your HVAC Winter Preparation

Complete HVAC system inspection should be done twice a year. Once in the Spring to prepare for the summer heat, and once in the fall to prepare for the winter cold. As your system ages, it will be more important to continue regular maintenance to ensure that HVAC components stay efficient to prolong the lifespan of your HVAC system.

HVAC System Maintenance: 5 Reasons Why Your Heating Costs Are Through the Roof

HVAC System Maintenance

5 Reasons Why Your Heating Costs Are Through the Roof

Heating costs are sure to rise as the outdoor temperatures fall during winter. If you notice your heating costs increasing each year, it is safe to say that your HVAC System may be showing signs of aging or needs repair. The most common sign is that your heating system is losing efficiency.

The more your HVAC System loses its ability to heat your home, the more it will cost you to achieve the same level of comfort. Here are some of the most common causes for your heating system to lose its efficiency.

How do furnaces lose efficiency?

  1. Dirty HVAC Air Filters

Your HVAC filter being dirty is the leading cause of heating system inefficiency. Replacing your air filter regularly will keep efficient airflow through your HVAC system. Clogged air filters reduce the airflow causing multiple components to drop in performance. Continue neglect of replacing your air filter regularly can even result in system failure.

Most air filters are scheduled to be replaced every 60 to 90 days. Pet owners, tobacco users, and those with elderly or small children in the home may consider replacing their air filter more frequently.

  1. Dust and Debris Buildup

The air filter will only remove a certain amount of dust and debris from settling on your components. This build-up will reduce their efficiency. Your HVAC System coil is one component that is expensive to replace and whose lifespan can be increased with proper cleaning. Your HVAC system has two coils, an evaporator coil, and a condenser coil.

Dust buildup on your evaporator coil reduces the ability to reduce humidity in your home’s air. Debris buildup on the condenser coil limits the condenser coil’s ability to release that heat outside.

The best way to prevent dust buildup is to have your heating system undergo preventative maintenance twice a year. Once in the spring and once in the fall. Our experienced technicians will clean and shore up your system and report any potentially problematic areas to address.

  1. Failing Ductwork

Your ductwork is the delivery system for cooling and heat to your home. When this delivery system is compromised, that system is less efficient and your HVAC system must work harder to achieve the same level of comfort. During a preventative maintenance appointment, our technicians thoroughly inspect your ductwork to identify any wear and tear or potential areas that may cause improper air flow.

  1. Blocked or Close Air Vents

Many times we forget to keep air vents free of furniture or rugs, and sometimes we close air vent to attempt to redirect airflow. Without a zoning thermostat, your heater will continue to heat that room regardless.

  1. Aging Heating Systems

The average lifespan of your HVAC system is about 15-20 years. Proper maintenance can increase lifespan considerably. As your system ages, it will decrease its efficiency. As technology increases, systems become more efficient, work less, and last longer.

3 Reasons Why Winter HVAC Repairs Should Be Addressed Immediately

3 Reasons Why Winter HVAC Repair Should Be Addressed Immediately

Repairs to your HVAC system are not something that you want to delay. The longer you delay these repairs, the more costly they can become. Scheduling your HVAC repair early in the fall can provide you with the best appointment times. As we get further into winter, there will be fewer available appointment times.

Avoid Costly HVAC Repairs

If your HVAC system has shown any signs of wear and tear, you will want to address that repair as soon as possible. Minor problems with your HVAC system can lead to major repairs if left unaddressed. Neglected repairs can even lead to the replacement of an entire HVAC system if the component damage becomes too extensive. Waiting for your HVAC system to fail can cause your repair to be delayed if the repair technician’s appointments are already booked, or multiple components become impacted.

Reduce Your Exposure and Risk to Emergency Repairs

Emergency repairs can be very costly. Many HVAC repair companies increase appointment fees for after-hours or weekend appointments. You will want to avoid these unnecessary charges by scheduling your repair at the first sign of a problem. Don’t put your self at the mercy of a total system failure, when the timing is beyond your control.

Increase Your HVAC System’s Lifespan

3 Reasons Why Winter HVAC Repair Should Be Addressed Immediately

Neglecting regular maintenance or timely HVAC repairs can shorten the lifespan of your HVAC equipment. Regular maintenance will keep components operating at their highest level and will identify potential problems before they become more serious. Without these services, your air conditioning equipment might need to be replaced sooner than you expected.

Energy Efficient HVAC Tips for Summer

Summer Energy Efficient HVAC Tips

Summer Energy Efficient HVAC Tips

Being cool is the number one priority for most of us during the intense summer heat. HVAC systems work overtime to remove the heat and make our homes comfortable and safe.

Cool summertime temperatures come with a cost. Homeowners see spikes in utility bills and must question their choices and consider energy-efficient alternatives. Here are some solutions to reduce your energy consumption during the summer.

Important Facts About Energy Efficient HVAC

Do you know what percentage of your utility bills come from your HVAC system? Let us take a quick look at some facts to help you better understand your HVAC system efficiency.

In the Texas Gulf Coast, over 95% of homes use some type of cooling system. In the U.S., 12% of the total energy consumption is from air conditioning systems. In Southeast Texas, that number is over 30%. Reducing the amount you use your air conditioning system is the easiest way to reduce your energy usage, but the cost is not worth it. Yes, your bill is lower, but often your comfort level is also below what is acceptable.

Energy Efficient HVAC System Upgrades

Older HVAC units are not as energy-efficient as newer and more modern options. Newer air conditioners are required by the Department of Energy to meet certain energy efficiency standards. Over time your HVAC system will lose efficiency. The older your unit is, the harder it has to work to reach the same comfort levels that you are used to.

Redesign Your Energy Efficient HVAC System in Your Home

Air conditioning systems work to cool your home. Rarely does each area of your home stays the same temperature or have the same cooling requirements. Zoning HVAC systems create comfort levels designed exactly like what you need and want. Zoning thermostats can redirect airflow to specific areas of your home as needed. This keeps the temperature consistent, between floors and rooms to provide the cooling and heating level you desire.

A zoned Energy Efficient HVAC system provides comfort and precision, and it helps you use less energy. Zoned HVAC systems can reduce airflow to unused rooms so energy is not wasted cooling/heating areas where nobody will be using it. When you pair your zoned HVAC system with a zoning thermostat, you can see additional savings that can further reduce your utility bills.

How To Unclog Your AC Drain Line?

How To Unclog Your AC Drain Line

AC Drain Line Maintenance

Clogged condensate drain lines can cause expensive repair that can be avoided. There are ways to prevent water leaks from a clogged AC drain line. Here are the steps to thoroughly clean your AC drain lines.

Step 1: Turn Your AC System Off

Some air conditioning systems will shut off if the condensate line becomes clogged. However, if you notice that the drain line is clogged, turn off your system. If your HVAC system continues to work, it will continue to drain water which can cause your drain pan to overflow causing water damage.

Step 2: Locate Your AC Condensate Drain Line and Runoff

Every HVAC system has a condensate drain line that runs from the indoor air handler to a location outside your home. This drain line removes the water from your AC system as it dehumidifies your home.

In order to unclog your AC drain line, you will need to locate your condensate drain line runoff and have access to it in order to clear them.

You will need to know the location of both your condensate drain line runoff and access to clear the clog.

Step #3: Removing the AC Drain Line Clog

At your drain runoff, attach a wet/dry vac hose to the end of the drain line. You can use a towel or duct tape to make the connection to the drain line more airtight. Run the vacuum a few minutes to blow out any debris or build-up.

You may need to blow air out the drain line, or you may need to use the vacuum as a vacuum to remove the clog. You may need to repeat these steps a few times to completely remove the clog.

For difficult clogs, you may try a mix of bleach/distilled vinegar and hot water to remove build-up. This will help break down the clog and make it easier to remove.

How To Unclog Your AC Drain Line

How to Prevent Future AC Drain Line Clogs?

We recommend that you take preventative measures to reduce AC drain line clogs. Pouring a cup of bleach down your condensate line will kill mildew and algae and prevent future growth inside the drain line.

Have a clogged AC drain line?

If you suspect your AC drain line is clogged, avoid costly repairs and call us at 281-238-9292 or contact us via email. The longer you ignore or put off making the call, the most costly the repair can be.

Avoid Costly AC Repair with this Simple Suggestion

AC Repair: Best Practices to Avoid AC Repair

AC Repair Money Saving Tips

When was the last time you changed your air conditioning filter? If you don’t recall, it has definitely been too long. During the intense heat of a Texas summer, your AC system takes a beating. Contaminants, dust, and debris fill your home’s air. Expectations of your air conditioner filter to miraculously perform when you attempt to extend its life is dangerous and costly.

A leading cause of AC repair and air conditioning repair is the failure to replace your filter timely.

Top Excuses We Hear To Why The AC System Filter is Not Changed Regularly

– I didn’t remember to change it

– It is not “that dirty” it doesn’t need to be changed

– I am unable to change them myself

– I don’t know which filter to buy

This simple act can save you costly AC repair and prevent air conditioning repair that can eventually force you to replace the entire HVAC system.

Setting a calendar reminder on your computer or smartphone to remind you to change your filter is an easy solution to forgetting to change the filter. If your filter is not dirty after six months, chances are it was not properly installed from the beginning. Improper filter installation can cause serious damage to your system components. If you need assistance in installing your HVAC filter or knowing which filter to install, All Cool AC offers AC repair and maintenance.

How To Tell You Need AC repair or Air Conditioning Repair/Maintenance

New homeowners or renters may find it difficult to tell if they need to schedule an AC repair appointment with a professional HVAC technician. Being unfamiliar with the baseline of efficiency of your HVAC system allows you to judge when something is amiss more easily. Remember that addressing any issues quickly will prevent more serious system failures in the future. Here are the most common signs that you need air conditioning repair.

Reduced Airflow of Cool Air

This is something you will notice quite quickly and easily. If you start the system and your AC does not turn on it is a good sign that your system needs repair. If your system does engage but you find there isn’t enough airflow, or the air is not cool, it can indicate that the ductwork is clogged or the ductwork has disconnected. A reduction in airflow is one of the clearest indications that your AC is in need of repair.

Moisture and Condensation Buildup

When warm air and cool air mix, the result is condensation. When your air conditioning unit is working efficiently, the unit handles the condensation with no problems. If moisture and leakage begin to build up and become visible around the unit, it can mean that you have a refrigerant leak. Refrigerant leaks cause significant damage to your unit, and if neglected, it can lead to health threats to you and your family. If it is condensation, rust and mold can result, which can lead to a costly repair that extends beyond your HVAC system.

Vibrations or Mechanical Sounds

If you begin to hear noise coming from your air conditioning system or ductwork, it may be a sign that you need to schedule an AC repair appointment. Squeaking, grinding, excessive vibrations, and mechanical noises are also a sign that your air conditioning unit is aging and may need to be replaced. This is one of the most noticeable indicators that you need AC repair.

Need AC repair or Air Conditioning Repair?

If you are experiencing a noticeable decrease in the functioning and efficiency of your HVAC system, you need to call us at 281-238-9292 or contact us via email. The longer you ignore or put off making the call, the most costly the repair can be.

UV Light Sanitizers for Your HVAC System

UV Light Components for Your HVAC System

What an Air Purification System Can and Can’t Do

Reduce Indoor Air Pollutants with an Air Purification System

During this current pandemic, we see countless numbers of ads about the different sanitizing products on the market. Some are effective, while others are not. The most proven method of removing indoor air pollutants is using UV light sanitizers within your HVAC system. Although a UV light system inside your HVAC system cannot prevent contaminants from entering your home on your person or through open doors or windows, it can kill mold, bacteria, and some airborne viruses. This can be a great addition to regulate your indoor air quality within your HVAC system. This is especially critical for those with compromised immune systems, sensitivity to allergens, asthma sufferers, or children.

In 2012, Duke University conducted research providing evidence that UV light sanitizers can significantly reduce mold, bacteria, and virus transmission when combined with standard cleaning solutions. Although commercial based cleaners are not used in most homes, UV light sanitizers can be added to many existing HVAC systems.

The common method of adding these components is done in two ways:

Coil Sanitization

UV Light Components for Your HVAC SystemYour HVAC’s indoor coil can be fitted with UV C components to remove mold and other contaminants. Your coil removes liquid from the air to dehumidify your home. As air flows over the moist indoor coil, dust, debris, pet dander, and other pathogens stick to the coil. The coil can have mold and fungus grow if it is not cleaned regularly. If neglected those same allergens can enter your indoor air.

Coil sterilization light can remove irritants from your coil. The UV light sanitizers will direct its focus on the coil itself to kill everything before it gets into your indoor air quality. With a professionally installed UV light sanitizer, pollutants are removed 24/7 since the light remains on at all times. When a UV light is paired with a quality HVAC air filter, you will be provided some of the best indoor air quality possible.

Air Sanitization

Air sanitization products are a step beyond HVAC system coil sanitization. The air sanitization components use activated carbon to remove odors and chemicals from indoor air. Hazardous fumes from carpet, furniture, household cleaners, and industrial solvent concerns make your HVAC system an excellent candidate for this technology advancement.

In this world of pandemic crisis, we are all looking for the best solution to indoor air quality. We want to protect our family, our home, and our pets from pollutants, contaminants, and pathogens. Although HVAC UV light sanitizing components are not foolproof, they will take your indoor air quality protection to the next level. They are a great solution to remove bacteria, viruses, chemical irritants, pet dander, dust, and debris. These are all common irritants for those with chronic respiratory issues, sensitivity to chemicals, and asthma.

UV Light Sanitizer Questions

If you have questions about UV light sanitizers for your HVAC system, call All Cool A/C today at 281-238-9292. We look forward to working for you in the near future.

Perhaps the most important acronym for new systems, SEER stands for Seasonal Energy Efficiency Ratio and measures the overall efficiency of air conditioning equipment during operation. As of January 1, 2015, the minimum allowable SEER rating for new air conditioning systems throughout the United States is 13; SEER ratings of 14 are required for systems in our area. Choosing a unit with a higher SEER rating can significantly reduce your cooling bills and can provide you with added comfort during hot Texas summers.

Modulated Air Conditioning Systems

Also known as variable-speed systems, modulated equipment offers more than simple on-off functionality for homeowners. By varying the amount of power devoted to keeping your home cool, these systems offer improved energy efficiency and more accurate climate control for your family. If you are in the market for a new HVAC system, consulting with your Katy air conditioning service professional can provide added guidance in finding the right solutions for your cooling needs.

Load Calculations

When replacing your current system, your Katy installation experts will typically perform a load analysis to determine the right size and capacity for your home’s size and cooling needs. These load calculations are essential to ensure that you enjoy the greatest possible indoor comfort and the most efficient operation of your new heating and cooling equipment.


An acronym for Minimum Efficiency Reporting Value, MERV ratings indicate the ability of air filters to remove particulate matter from the air. Filters with lower ratings provide less protection against small particles. MERV 16 filters are suitable for use in hospitals and clean rooms. Consulting with your air conditioning technician can help you choose the right filter for your system and your indoor air quality needs.


In the HVAC industry, zoning refers to the use of separate thermostats to manage climate control in various areas of your home. For instance, a large family room might require its own thermostat while all bedrooms on a single floor might share a zone and a common thermostat. Zoned systems offer greater flexibility and can be especially useful in families with widely different preferred temperatures in their personal living spaces. By implementing heating and cooling zones, you can ensure individualized comfort in every area of your Texas home.

British Thermal Units

British thermal units, also known as BTUs, are a way to measure the cooling power of a particular air conditioning system. One BTU is defined as the amount of energy required to increase or decrease the temperature of one pound of water by one Fahrenheit degree. BTUs are used to describe the size of cooling systems and to allow proper sizing of equipment for homes and buildings of all sizes. Working with an experienced HVAC company can ensure that your new system has enough power to keep your home cool all summer.
