Indoor Air Quality

To maintain a constant and regulated temperature, HVAC systems recirculate air through the system rather than pulling in new air from outside. Because air is not being replenished, you are protected from exterior variables like pollution and pollen. However you are still vulnerable to indoor air pollution. Without a proper filtration system setup, the air in your home can spread mold, dust, smoke, pet dandruff, and other airborne pollutants throughout your home or building.

Penguin Air offers effective indoor air quality improvement solutions which will maintain healthy and pollutant free air inside your home. If you are suffering from irritations including itchy eyes, coughing, sore throat, wheezing, headaches, or lightheadedness, you may be exposed to indoor air pollutants.

Indoor Air Quality Testing

If you suspect there is an issue with the air in your home or building, we offer comprehensive and thorough indoor air quality testing services. An indoor air quality test will not only check for levels of pollutants in your home but will also pinpoint the sources. Some issues affecting your indoor air quality may be due to water damage which will need more intensive repair services.

Duct Cleaning

Because air circulated through your HVAC system, over time pollutants can build up on the inside of your air ducts. The main cause of pollutants in your air ducts is improper air filtration, but moisture and air duct leaks can cause pollutants to build up. Here in Texas we commonly find mold and mildew in air ducts during the winter and spring months where condensation can build up from the temperature difference between the outside and indoor air.

  • Vacuum furnace and air conditioner unit’s housing, coils, blowers and vents.
  • remove wall and ceiling vents and clean with safe chemicals to remove dust and particle build up
  • Use duct cleaning equipment to remove particles and spray cleaners to kill odors and prevent mold build up.

UV Lights

Ultraviolet radiation occurs naturally outdoors and kills bacteria, germs, and other fungal growth. UV lights can be added to your HVAC system to purify any airborne bacteria circulating through your home. UV lighting systems are used in extreme situations to offer the maximum amount of protection from airborne pollutants.


It is common here in Texas for the air inside a building to dry out over the summer and winter months when an HVAC system is constantly running. When air is heated in a furnace, the water will evaporate and condense, and when air is cooled down in an air conditioner, moisture will condense and collect on the refrigerant pipes. The main use of an HVAC unit isn’t to dehumidify the air, but it can cause your air to become dry over an extended amount of time. Humidifiers will add much-needed moisture to your home and will help alleviate some of the effects of dry air including irritation to your skin, dry mouth and eyes, bloody noses, sore throats and allergies.


In the hot and humid Texas summers, the humidity can build up indoors and cause issues with mold and mildew. Dehumidifiers can be incorporated into your HVAC system or can be placed from room to room depending on where moisture levels are the highest. B Bathrooms, kitchens, and laundry rooms will have excess amounts of moisture from the use of steam.
