Filters
AC Filter Services in the Denver Metro Area
Ensuring that your air conditioner is running properly and will continue to do so throughout the hot and humid summer months usually comes down to proper maintenance. Your AC system’s filter is one of many pieces of the air conditioner that plays an important part in keeping your system running smoothly and efficiently. When your ac filter is not properly serviced and maintained, it can cause problems with your AC System. Dirt and debris can clog the filter restricting airflow which could then allow dirt to get on the evaporator coil which will impair the way the coil absorbs heat. This can cause even the best AC System to function improperly and can even lead to failure of the compressor or fans.
It’s important to have the correct solution to your heating & air conditioning concerns. D&A Heating and Air offers custom installations and replacements. We offer emergency service on air conditioning and heating units, refrigeration and air filtration systems, as well as commercial roof top unit sin the Denver Metro Area.

Humidifiers
The Benefits Of A Humidifier
In addition to the obvious benefit of permanently preventing dry air inside your home, whole house humidifiers have several additional benefits, including:
- Sleeping in an environment with a healthy humidity level considerably helps prevent sinus issues and dry skin.
- Controlling a home’s relative humidity properly will help the indoor air feel warmer. You’ll be able to lower your thermostat and save money without feeling the heat difference.
- Proper humidity control substantially reduces static shock and the dangers accompanying it.
- Whole house humidifiers require much less maintenance than smaller humidifier units.
- A home humidifier will help keep you healthier, save money, and create a more comfortable living environment.

How Do Whole House Humidifiers Work?
Whole house humidifiers are installed directly into the ductwork next to your furnace. They use heated air coming from the furnace to evaporate water. Then, fans in your HVAC blow the drier air across the evaporated water and then distributes the newly humid air throughout your home. As long as the whole house humidifier operates, it will continue to add water to the air circulating through your home and prevent dryness.
The best whole house humidifier for Colorado homes will automatically adjust to a specially programmed moisture level appropriate for the Denver-Boulder area (or wherever you live). You have a wide variety of brands and sizes to choose from depending on your home’s needs. A technician who can install a whole house humidifier will help you select the right option for your home.

- Use your window shades and drapes to maximize heating benefits. Keep shades closed at night to conserve heat. During the day, open shades to let the sunlight in.
- Add humidity. Humid air feels warmer than dry air. Increasing the humidity of your home also helps you resist winter colds and moisturizes dry skin. Ask us about Trane Humidifiers!
- Much of the heat escaping homes is lost through the attic. Be sure to close off any attic vents or fans during the winter and check on how well the attic is insulated. Our technicians can help!
