Residential Indoor Air Quality Testing Services in Houston, TX

Indoor air quality (IAQ) has become a serious health issue that is found most often in energy-efficient homes. Sealed building envelopes trap pollutants in the living area, which can negatively impact those with asthma, allergies and other respiratory conditions

Indoor Air Quality Testing

Armstrong Air dealers in and around Houston, TX, provide complete indoor air quality testing services for homes and businesses. Many IAQ issues are intermittent and hard to pinpoint. In most cases, the problem only becomes apparent when someone who is in the building regularly experiences eye irritation, skin rashes, allergies or breathing difficulties. Depending on your symptoms, our contractors use state-of-the-art equipment to test the air in your home to identify the source of the contamination.

While there are many types of environmental pollutants, testing protocols typically focus on the organisms and substances that cause the majority of IAQ issues. These include mold, fungi, bacteria, combustion-related byproducts, VOCs, carbon monoxide, and more.

When your home is tested, it may seem like the process revolves around meters, sensors and data recorders. However, the skill of the service technician is vital in properly interpreting the data and making the correct diagnosis. All of our contractors are skilled and experienced in pressure testing, sampling and remediation.

Indoor Air Quality Products

Commercial buildings and homes with substandard air quality often have multiple sources of contamination, so qualified contractors blend a variety of different elements into a comprehensive IAQ strategy.

  • Air Purification Systems: Air filters play an important role in cleaning the air as well as protecting your HVAC equipment. Modern filters are engineered to trap particles as small as .3 microns, including pollen, spores and even some gasses. Most HVAC contractors recommend installing a filter with a MERV 7 rating, but you should check with your contractor to verify if your system has enough static pressure to accommodate a high-efficiency filter.
  • Humidifiers: The humidity in your home should always range between 30-50 percent. When the air is too dry, airborne contaminants linger and ride the air currents until they are inadvertently inhaled. If the air is too moist, mold, fungi and other biological organisms grow. Central humidification and a correctly sized air conditioner will help keep the air inside your home properly humidified in all seasons.
  • Ventilation: Homes that are too tight have little or no air exchange, and contaminants quickly build up inside the living area. A mechanical ventilator will introduce a steady stream of fresh air from outdoors while simultaneously exhausting the stale air from inside. Advanced models include an energy recovery feature, which helps reduce HVAC operating costs.
  • UV Light Systems: Third Coast Air and Heat can install a UV Light System in your home or office. This unique UV Light System is for killing bacteria, germs, odors, molds and mildew.

  • We have found the owner, Ray Mehrens, to be of the highest moral integrity. In addition he is very dependable and trustworthy. We have recommended this company to our family and friends.

    Ron H.

  • Thank you for being honest and hardworking. We had received a quote from a competitor - they recommended a full unit replacement at $15,000. Not only did Ray tell us we didn’t need a new unit, he said ours was still under warranty (something the other company failed to tell us). Ray recommended that we insulate the house better. Ray put insulation into our attic and did some outside ventilation work. Now that we are in the heat of summer, not only is our house cooler than it was in the past, but our electric bills are lower! We have told all our friends about Third Coast Air! They are now our go-to company. We appreciate you and the work you did. It used to take out house until well after 10 pm for the ac to stop running. Not the case any longer!

  • Thank you so much for working on my a/c. It was like you weren’t ever there! Which is a good thing. You didn't leave ANY lights on, no insulation all over the bathroom floor, a/c wasn't cranked down to 60– nothing! I am not used to someone being so conscientious about their work. Thank you Thank you Thank you!!
