Indoor air quality isn’t only important for your comfort, but also your health! According to the US Environmental Protection Agency, Americans spend about 90% of their time indoors whether at home, work, school, or other indoor location. Now, imagine spending almost all of your time at home while the air is too humid, dry, or dirty. You and your loved ones would be at risk for multiple damaging respiratory effects.

As a family-owned business, we make your family’s health our top priority. We have over 20 years of experience providing a wide range of air quality products and services to the Denver Metro Area. Find out more about the unique challenges that homes and buildings in Denver face when it comes to air quality, plus how our NATE-certified technicians can help.

Denver Home Air Quality Concerns

Dry Air in Denver

The Denver Metro Area is notorious for having dry air because of the high altitude, especially during winter when temperatures drop and heaters turn on. Cold air doesn’t retain moisture as well as warmer air. Plus, home heating causes what little moisture there is to dissipate further since it’s adding heat without adding any moisture.

The symptoms that someone would experience from dry air range from benign to more serious consequences:

  • Flaky or itchy skin
  • Bloody nose
  • Chapped lips
  • Headaches
  • Irritated eyes
  • Coughing
  • Bronchitis
  • Asthma

Dry air doesn’t just affect people either, your home and furniture can also feel the effects! Wallpaper, wood, furniture, and paper decorations can crack and break.

We offer whole-home humidifiers to effectively balance humidity and improve your air quality. In addition to a professional solution, there are DIY remedies that you can also implement to help combat dry air.

Humid Air

On the flip side, your Denver home may feel too humid during the warm summer months. When humidity levels remain at 60% or more, moisture in the air can make your home feel stuffy and cause mold growth. Mildew, mold spores, and bacteria cling to the air and cause sickness to those that breathe them in—especially those with respiratory illnesses like asthma.

If you see mold growing in areas of your home, contact us for more information about our whole-house dehumidifiers. Once one is installed, you can rest easy and breathe deeply.

Carbon Monoxide Poisoning

Easily one of the most concerning air quality threats to your Denver home is carbon monoxide (CO) poisoning. Colorado has a history of CO poisoning that has unfortunately resulted in several deaths. In 2020, data from Colorado's Department of Public Health and Environment showed that 48 people were hospitalized for carbon monoxide poisoning

Mild symptoms of CO poisoning include headaches, nausea, dizziness, difficulty breathing, and more. More serious symptoms of CO poisoning include loss of consciousness, heart attack, and death. Read our What You Need to Know About Carbon Monoxide In Your House blog for full information on the causes, symptoms, and Colorado history of CO poisoning incidents.

It’s not worth it to be at risk for such dire consequences. All it takes is a CO detector on each floor of your home to save you and your loved ones from CO poisoning. These CO detectors are available for $15-$30 at major retailers like Home Depot and Walmart, or UHC sells and installs them for you as well.


According to the Colorado Department of Public Health and Environment, roughly half of Colorado homes have higher levels of radon than recommended by the EPA. Radon is a radioactive gas that isn’t detectable by human senses and is the second leading cause of lung cancer in the US. It comes into your home from the soil when subterranean Uranium breaks down. 

The first step to fighting radon in your Denver home is to get a professional to test your levels or attain a home test kit. From there, radon reduction systems can be installed that draw inside air safely outside. If you think pipe venting is an eyesore and don’t want to make a hole in your foundation, we install air purifiers, which are equally efficient at lowering radon levels in addition to other contaminants.

If you see particulates floating in the air or smell out-of-place odors, a dirty HVAC system could be to blame. Several types of contaminants get trapped in ductwork and then circulated around the house, like:

  • Dead skin cells
  • Bacteria
  • Mold spores
  • Dust
  • Pollen
  • Dirt
  • Contagions

Other than regular duct cleaning through our HVAC Maintenance Program, we have many options for maintaining air quality in your home such as ventilators, UV lamps, air cleaners, and air purifiers. Contact us to see which is best for your home.
