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.

Indoor Air Quality: How Spring Affects Our Air Quality

Indoor Air Quality: How Spring Affects Our Air Quality

Spring has sprung! Pollen, mold, mildew, and dust are circulating in our air making for extremely poor indoor quality. If not maintained, these Springtime pollutants can have a big negative effect on you and your family’s health.

Indoor Air Quality Adverse Effects

  • – Itchy Eyes
  • – Congestion
  • – Body Aches
  • – Runny Nose
  • – Coughing
  • – Sneezing
  • – Fatigue
  • – Headache
  • – Dry Skin

Indoor Air Quality: How Spring Affects Our Air QualityAllergens such as pollen are in abundance in Spring and the leading cause of congestion and allergy flare ups. One of the reasons this contaminants flourishes during Spring is our tendency to “air out” our homes by opening the windows. This allows the pollen allergens to have full access to our sinuses.

Spring showers leaves dampness and moisture where mold and mildew find easy conditions to grow rapidly.

Throughout the entire year, your HVAC system pulls dust and debris into your ductwork settling to be recirculated as your air conditioning system works. This cycle of circling the dust in and out of the house will continue until the ducts are thoroughly cleaned. During Spring, outdoor pollutants and allergies have your sinuses and breathing labored, additional dust and debris from your ductwork can send your health spiraling downward.

What is the Roll of Your HVAC Systems for Healthy Indoor Air Quality?

Your heating and air conditioning systems filters and cleans your indoor air, maintains humidity levels, and provides comfortable temperatures. If properly maintained, HVAC systems will help filter that springtime pollen out of your home and will minimize the risk of mold growth by monitoring humidity levels.

Your HVAC Air Filter is a Crucial Component to Indoor Air Quality

A common problem for many homeowners is your AC unit “freezing up.” This is when your HVAC system is overworked. Its effectiveness becomes compromised and electricity usage can increase drastically.

Leading Causes of A/C Freeze Ups

Your HVAC evaporator coil drops too low, your system will begin to ice up. Hot airflow has become obstructed. Rather than moving hotter air from your home, the evaporator’s coils begin the transference of ice-cold air.  Such an occurrence is an example of poor system airflow.

Here are the leading causes of poor airflow:

  • – Clogged or dirty air filters
  • – Lack of refrigerant level
  • – Curtain/drapery/furniture obstructions for air returns
  • – Dirty or clogged coils
  • – Poorly functioning or malfunctioning system fans

Repair It Now or It Will Cost You

If you notice that your HVAC system is performing poorly, running excessively, your utility bill skyrockets, noises or smells are coming from your air conditioning unit, call for service immediately. Fixing an air conditioning system quickly as issues are noticed, will reduce expensive repair down the road.


How Indoor Air Quality Can Affect Your Health

Did you know that most people spend about 90% of the lives indoors? Did you also know that indoor pollutants are as high as 100x’s of the level outside. The EPA (Environmental Protection Agency says that indoor air pollutions is one of the top environmental hazards in the United States.

With viral pandemics in the news on a daily basis taking precautions to reduce exposure have never been more important. Bacteria, viruses, mold and other diseases can spread through your HVAC system. One of the best ways to protect you and your family from these contaminants is by investing in an indoor air quality system.

Common Methods of Virus Transmission

Airborne Transmission

How Indoor Air Quality Can Affect Your HealthMany viruses are spread through respiratory droplets. These droplets originate when an infected person coughs or sneezes and the resulting droplets become airborne. These contaminants can spread through your air conditioning system, mixing with your home’s air supply, and be spread throughout your home. The HVAC system and ductwork can contribute to spreading unwanted pathogens in the air, not because your system is contaminated as a factory defect, but because the air in your home is contaminated.

There is the possibility to have airborne water droplets small enough that they stay airborne for an extended period. It is also possible that these particles could be sucked into a HVAC system return grille, travel through ductwork, and infect someone else in a different area.

Intermediate Surface Transmission

Here is an example of intermediate surface transmission. An infected person coughs or sneezes and “catches it” in their hands. They can then lave infected droplets on surfaces that they touch like: doorknobs, counters, shopping carts, gas pumps handles, or other frequently shared surfaces. A person not infected then touches those surfaces and rubs their eye, touches their mouth, or scratches their nose. The virus has now been transmitted from one person to another.

An Ounce of Prevention

Recent studies in airborne disease has identified three preventative methods that can control airborne infections. They particulate filtration and ultraviolet light.

HVAC Allergen Control Filters

Air filters can reduce the transmission of infectious airborne viruses. The issue remains unclear is how efficient does the filter have to be to significantly remove infected particles present. There are allergen resistant filters on the market. The more dense the filter material, the more likely it is to remove smaller contaminants.

There are HEPA (high-efficiency particulate air) filters that are 99.7% effective in trapping even the smallest of viral particles.

Ultra+-Violet Light

Ultraviolet disinfection systems for HVAC units are a great addition to conventional filtration. UV disinfection systems can remove microorganisms that are typically small enough to pass through filters. We know that HVAC system filters are designed to capture larger particles. How Indoor Air Quality Can Affect Your HealthSurface ultraviolet and airstream ultraviolet disinfection systems deactivate pathogens. UV disinfection systems are shown to reduce microbial load and pathogens commonly found in HVAC systems and drain pans.

Surface-cleaning UV-C systems provide 24/7 irradiation of HVAC components to destroy bacteria, viruses, and mold that settle and proliferate on coils, air filters, ducts, and drain pans, preventing the growth of pathogens that can eventually become airborne and get circulated by HVAC systems.

Better Indoor Air Quality Means Everybody Benefits

Implementing an indoor air quality system will greatly benefit those in your family who may be susceptible to airborne contaminants. Children, elderly, immune-compromised, and those with asthma are vulnerable to airborne contaminants. Improving your indoor air quality will greatly improve the life of those in your home.
