The combination of Centennial’s dry climate, older construction, and HVAC systems that recirculate the same indoor air makes indoor air quality a real issue for many homeowners. Relative humidity in Centennial homes during winter can drop to uncomfortably low levels that dry out skin, damage wood floors and furniture, and increase susceptibility to respiratory illness. Dust, allergens, and airborne particles accumulate in homes with standard filters that are not designed to capture fine particulates. And homes with gas appliances and attached garages have potential combustion byproduct and VOC sources that standard HVAC filtration does not address.

For duct cleaning as part of an overall air quality improvement, our air duct cleaning service handles that scope. For HVAC maintenance that keeps the system clean and filtration effective, our HVAC maintenance service covers seasonal tune-ups. See all Centennial HVAC services we offer.

• Whole-home humidifiers integrated with the HVAC system to maintain comfortable humidity levels throughout Centennial homes during the dry winter heating season.
• High-efficiency air filtration systems that capture fine particulates, allergens, and airborne pollutants that standard one-inch filters miss.
• UV air purification systems installed in the air handler to reduce airborne bacteria, viruses, and mold spores circulating through the ductwork.
• Energy recovery ventilators for tightly constructed homes that need fresh air exchange without the energy loss of simply opening windows.
• Air quality assessment to identify the specific indoor air quality concerns in your Centennial home and recommend solutions that address the actual issues.

Here are the indoor air quality systems our Centennial technicians install most often.

How Dry Should Indoor Air Be in a Centennial Home?

The EPA recommends keeping indoor relative humidity between 30 and 50 percent for comfort and health. In Centennial during winter, outdoor air is very dry, and running a furnace that heats this dry outdoor air makes it even drier as relative humidity drops with rising temperature. Many Centennial homes see indoor humidity fall to 15 to 20 percent or lower during peak heating season without a humidifier, which is dry enough to cause nosebleeds, dry skin, static electricity buildup, and cracking in wood floors and trim.

A whole-home humidifier integrated with the HVAC system adds moisture to the air as it is heated and distributed, maintaining comfortable humidity levels automatically based on outdoor temperature. This is a more effective and less maintenance-intensive solution than portable humidifiers in individual rooms. WireNut installs bypass, fan-powered, and steam humidifiers depending on the home’s humidity needs and HVAC configuration.

What Is a UV Air Purification System and Does My Centennial Home Need One?

A UV air purification system uses ultraviolet light installed in the air handler or ductwork to reduce airborne and surface-level microorganisms including bacteria, viruses, and mold spores as air passes through the system. UV systems work by disrupting the DNA of microorganisms, rendering them unable to reproduce. They do not filter particles from the air the way a mechanical filter does, so they are most effective in combination with a good filtration system rather than as a standalone solution.

Centennial homeowners with family members who have respiratory sensitivities, frequent illness, or concerns about mold in the ductwork are the most common candidates for UV air purification. WireNut can assess your specific situation and recommend whether a UV system, a filtration upgrade, or a combination of both makes sense for your home.
