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.
