Indoor Air Quality

Indoor air qualityIf you want to improve your home or office’s indoor air quality, we offer several solutions. Adding equipment to your existing heating and cooling system can help with regulating humidity as well as reducing allergens, pet dander, dust, mold, bacteria and static electricity.


A whole-house humidifier can increase your comfort, reduce allergens, alleviate static shocks and even help lower your heating bills. People feel most comfortable when the indoor humidity level is between 30% and 50%. Running the heater during Iowa’s cold winter months can lower the relative humidity inside your home to 15% or even lower. The average relative humidity in the Sahara Desert is 25%, so that means the air in your home can get drier than the desert.

Dry air also causes discomforts like itchy skin, irritated nasal passages and static electricity. Even your home’s furnishings can be affected, such as wood furniture or hardwood floors that can dry up and separate at the seams.

Properly humidified indoor air will raise the humidity level to about 35-55%. Air with more humidity feels warmer, so you’ll feel more comfortable at a lower temperature. This will allow your furnace to run less and use less energy.

HVAC Ultraviolet Lights

Ultraviolet (UV) light has been used to sanitize equipment for more than 100 years. UV light has been shown to kill viruses, mold and even antibiotic-resistant bacteria. Germicidal UV light is used for sterilization in restaurants, hospitals and even grocery stores.

In HVAC systems, UV lights may be referred to as germicidal, purifying, sterilization or sanitizing lights. They are located either near the indoor coil or inside the return air ducts. UV germicidal lights kill bacteria, mold, fungus, germs and other microbes that can aggravate allergies and asthma, cause musty odors in the home and even clog the HVAC system. The lamps can be plugged into an outlet or wired into the system. 

Coil UV lights shine on the surface of the coil, which condenses moisture and removes it from the air when the AC runs. The coil’s surface is wet, so it collects pet dander, dirt and other pollutants as air passes over it. This is a perfect breeding ground for mold or bacteria to grow and then disperse throughout your home in the air. High-quality UV germicidal lights, like those from Carrier, kill germs, bacteria and mold, as well as keeping the coil free of pollutants.

Air UV lights are installed inside the central air system’s return air ductwork. They kill mold and germs in the air that passes through the ducts. Lamps are typically either a U-shaped or stick design. Depending on the model, air HVAC germicidal lights can be hardwired into the system, so the UV light only turns on when the blower is running.

I had my air conditioning go out during a VERY hot day in June, 2017. I called three places (all recommended). Aspen Aire called me back right away (much appreciated) and had a technician out within 2 or 3 hours. I was amazed as it was an extremely hot day and assumed they would be really busy (and they were).

(Oh - the other two places? One never called me back and the other called me a week later with apologizes - heh!)

After installing a new fan in my condenser unit, it was determined that was not the problem. Given that the unit was 20 years old I opted to replace it as well as the 20-year old furnace. They did not try to talk me into doing that but gave me options - I decided to go with a new AC and furnace unit combination. They did tell me my AC and furnace were probably on borrowed time but, again, they did not push me to replace them.

Long story short, within a few days they had replaced the air conditioning unit and furnace with two really nice units that have long, transferable warranties.

The men were very professional, extremely clean, most polite and a pleasure to have in and around my house.

If you are need of heating and cooling services, you will never find a better company than Aspen Aire. I do not say things just to be nice. In fact I am a rather hard customer to please (truth be told!). But my experience with Aspen Aire was beyond my highest expectations.

On one hand it was unfortunate when my air went out on a 90 plus degree day. On the other hand it turned out to be a good thing since my experience with this company was so good.
