When it comes to whole-house heating and cooling systems, ductwork is the most common way in which heated and/or cooled air distributed throughout homes. This is also a very effective means by which to do so. However, it is possible for ductwork to be damaged, to corrode, or to otherwise be compromised. When this happens, a number of problems can develop in your living space. You cannot see most of your ductwork, so recognizing that there is a problem can be somewhat problematic to begin with. Professional duct repair in Houston, TX can be immensely beneficial if you suspect that there is a problem with the ductwork in your home.

There are a lot of challenges that one must overcome in order to live comfortably throughout the year in the Houston, TX area. Our summers are long and intensely hot, and temperatures can drop to shockingly low levels during the heating season. However, it is important to remember that temperature is not the only consideration to keep in mind when it comes to your overall comfort.


Your air conditioner and heating system contains an air filter which helps to filter pollutants out of the air you breathe. Air is sucked into the AC system from your home before it is conditioned so that your air conditioner is not damaged and to make the air that comes out a little bit cleaner. But this filter cannot eliminate every contaminant from your air. An additional indoor air quality system is necessary when members of your family are affected by the dirty air, such as UV germicidal lights.


Indoor air quality products help to eliminate additional smaller particles that sometimes make their way into the ducts. Or in some cases, they eliminate only a certain type of contaminant. This is true of UV germicidal lights, which kill microorganisms which cause adverse health effects when inhaled. This includes bacteria and viruses which are known to aggravate the sinuses, cause illness, and irritate allergies or asthma.


UV germicidal lights differ from other indoor air quality products in that they specifically target biological contaminants. UV light kills small organic matter. While you may go unharmed laying out in the sun for 30 minutes, small organic matter like bacteria can be killed instantly. One portion of your home that could contain bacteria is the indoor air handler, since condensation collects on your indoor air handler during the cooling process. The UV germicidal lights are installed at the air handler to eliminate living organisms already present or those moving through the ducts.

The air in the average home is absolutely infested with millions of microscopic particulates. These particulates are not all harmful. You don’t even notice the vast majority of them. However, there are plenty of airborne particulates that can irritate your lungs and even cause sickness. Various strains of viruses and bacteria are common, as well as mold spores that often circulate from a source colony in the ducts of your home. All of these pollutants can have adverse effects on your health. So, what are you supposed to do about it? Let’s take a look at UV germicidal lights, and how they can help improve the air quality in your home.


A UV germicidal light is a type of air purifier that works by bathing the area around itself in ultraviolet radiation. This radiation is of a shorter wavelength than sunlight, and not harmful to humans. These lights can be used as portable systems, or installed in the ducts as a whole-house system. A whole-house germicidal light will treat all air being circulated through the ducts of the house, vastly increasing its reach compared to its portable variants.


Many microscopic organisms, including many viruses, bacteria, and mold, are extremely susceptible to certain kinds of radiation. When exposed to that radiation, like the kind that the UV light gives off, these organisms are either sterilized or killed outright. This is because the radiation interferes with their cellular processes, rendering them unable to reproduce or operate effectively.

A UV germicidal light improves the air quality in your home by killing many of the microscopic germs and other organisms that can make you sick. This makes it especially popular in the homes of people with compromised immune systems or other conditions that increase their likelihood of infection. You don’t have to have any of those conditions to benefit from a UV germicidal light, however. Anyone who uses one will benefit from its protection.

You cannot see ultraviolet light as it’s invisible to the human eye. However, scientists have still discovered multiple purposes for these invisible wavelengths, including using UV rays for cleaning and sanitization. Ultraviolet radiation has long been accepted as a source of sanitization, ever since it was discovered in 1903 that certain wavelengths can kill bacteria. UV radiation is sometimes used to sanitize water as well, and it’s first utilization for water disinfection dates back to 1910.

One of the most popular ways UV lights are utilized today is in sanitizing and disinfecting medical equipment and laboratory equipment. Imagine if you could bring this same technology used to treat important medical equipment into your home. UV germicidal lights can be installed in your ductwork to eliminate many of the contaminants that may thrive in this hidden area. As air blows through the ducts and into your home, you breathe in these air pollutants, which may lead to illnesses. UV germicidal lights can benefit your home and family by removing any of the following contaminants.

  • Bacteria and Viruses: UV germicidal lights can sterilize microorganisms like bacteria and viruses, which could otherwise cause illness, so that they are no longer a concern for your home. This is because UV rays have the ability to harm organic matter. Although it doesn’t hurt humans to step out into the sun for a short time without sunscreen, a small amount can kill a microorganism like bacteria.
  • Mold Spores: The ducts are an ideal place for mold to grow as the indoor coil collects moisture during the evaporation process. The mold spores then blow through the ducts and into your air, aggravating any respiratory problems like asthma and allergies. UV radiation can take care of this threat as well.
  • Foul Odors: While it may not necessarily be a safety hazard, foul odors make your home an unpleasant place to be. UV germicidal lights may be effective at diminishing odors left behind from pets and cooking.

Do you like to sneeze every time the air conditioning cycle starts, or smell a musty odor? How about developing a consistent headache every time you are indoors? These are just some of the symptoms you can suffer from due to poor indoor air quality in Houston.

According to the EPA, indoor air pollution can be 2 to 5 times higher than that of outside air. Additionally, people spend an average of 85% of their time indoors, allowing for a high rate of exposure to any existing indoor air pollutants. But why does this matter? Our Expert Air technicians are familiar with the reasons why indoor air quality is important; here’s a quick look at 3 common types of contaminants that may possibly be in your indoor air:

Common Indoor Air Pollutants

There are a number of common indoor contaminants that can exist in your indoor air; here are 3 of the most common:

  • Volatile Organic Compounds (VOCs) – VOCs are gases emitted from solids or liquids. Common sources of VOCs are hairspray, cleaning products, pesticides, glues, adhesives, sealants, paints, stains, varnishes, stored fuels and automotive products. Some VOCs are more harmful than others, and the effects of VOCs on personal health can range from irritation of eyes and mucous membranes to skin reactions to headaches, nausea, fatigue and dizziness.
  • Respirable Particulates (RSPs) – RSPs can irritate the lungs, causing coughing and wheezing, and they can be especially problematic for those suffering from chronic respiratory illnesses such as asthma or COPD. RSPs can be particulates from a fireplace or woodstove, unvented gas heater, tobacco products and unvented kerosene heaters.
  • Biological contaminants – biological contaminants consist of a wide range of particle types: bacteria, viruses, mold, mildew, algae, fungi – it’s a long list. These types of biological pollutants love to live and thrive in cold, damp and dark locations, which can be numerous in an air conditioning system. Because the air in your AC system is delivered directly into your home, it may be delivering biological pollutants with it.

Consider an Air Cleaner

Your air conditioning and forced-air heating systems come equipped with air filters. These filters catch particles that enter the return air vents and prevent them from infiltrating the cabinet where they can damage important mechanical components. These filters will stop some of these particles from getting blown out the vents along with the conditioned air and into your living spaces.

However, these filters are not specifically designed to clean the air, just to protect the HVAC system. For practical indoor air quality purposes, the standard filters on air conditioners and heaters are ineffective. If you want increased air cleaning for your home, you need to consider installing mechanical or electronic air filters.

Knowing which of the various types of air filters in Houston, TX will work best for your home requires that you seek the help of indoor air quality specialists. Contact Expert Air Co and we can help you find the best solution to improving your indoor air quality with the assistance of professional installation of air filters.

Reasons to install air filters

  • Better health: The ventilation systems in homes gather large amounts of dust, dirt, carpet and furniture fibers, dander, and other contamination as they circulate air. Because modern homes have heavy heat sealing to enhance energy efficiency, very little fresh air gets inside to clean out this accumulation. The right filter will go a long way toward catching most contamination that flows through the ductwork. Mechanical filters can trap particles down to 0.3 microns, while electronic air filters can affect particles down to 0.1 microns and also stop gases and odor molecules.
  • HVAC system efficiency: A constant influx of dust and dirt into the ventilation system will place resistance against the airflow from an air conditioner or forced-air heater. This will make the AC or heater work harder and lead to an increase in your utility bills. Keeping the air cleaned with a filter will make your home comfort system’s job easier. (Just make certain you have the filters maintained regularly and cleaned to remove excess particles.)
  • A cleaner home: The average 6-room house will have 40 lbs. of dust circulate through it in a year… that’s a tremendous amount of dusting you’ll need to take care of to keep your home looking clean. If you have continual problems from dirt and dust in your home that no amount of cleaning seems to remedy, then you should consider an air filter. (You don’t want to be breathing these pollutants, either!)
