Done works on the full range of residential ventilation systems that serve Denver and Front Range homes — from the supply-and-return ductwork tied to your central HVAC system to standalone ventilation equipment like energy recovery ventilators, bathroom exhaust fans, whole-house fans, kitchen range hood venting, and attic ventilation. Proper ventilation is critical in Colorado, where homes are tightly sealed for much of the year and indoor air quality depends heavily on how well stale air is exchanged with fresh outdoor air.

Central HVAC Ductwork and Air Distribution

The duct system connected to your furnace and air conditioner is the primary ventilation network in most Colorado homes. Done repairs and replaces residential ductwork — sealing leaks that waste conditioned air and energy, replacing sections that have deteriorated, collapsed, or been damaged, and correcting duct layouts that were poorly designed and contribute to uneven temperatures or pressure imbalances throughout the house. Duct leakage is a common source of both energy loss and comfort complaints in older Front Range homes, where original ductwork may have decades of wear and improper modifications.

Duct cleaning is a separate service Done provides for removing accumulated dust, debris, allergens, and biological material from inside the duct system — particularly relevant after construction or remodeling work, extended vacancy, or when residents have allergy or asthma concerns.

Energy Recovery Ventilators (ERVs) and Heat Recovery Ventilators (HRVs)

Colorado’s dry, low-humidity climate and cold winters mean homes are sealed tightly for comfort and energy efficiency — but that tightness comes at a cost. Without intentional mechanical ventilation, indoor air pollutants (VOCs from building materials, CO2, cooking byproducts, pet dander, wildfire smoke particles) accumulate to levels well above what naturally ventilated homes experience. Energy recovery ventilators solve this by bringing in fresh outdoor air while recovering most of the energy from the outgoing stale air, so you’re not heating or cooling air you’re about to exhaust. Done installs and services ERV and HRV systems for homeowners who want controlled, efficient fresh-air ventilation.

Bathroom Exhaust Fans and Kitchen Ventilation

Bathroom exhaust fans are a basic but often neglected part of home ventilation. In Colorado’s dry climate, moisture management in bathrooms is still important — steam from showers can cause mold in poorly ventilated spaces, and that mold becomes an air quality problem throughout the home. Done installs and replaces bathroom exhaust fans, ensures they’re properly ducted to the exterior (not just into the attic, which is a common improper installation), and can add humidity-sensing fans that run automatically when moisture is detected.

Kitchen range hood ventilation — ducted to the exterior rather than recirculating — is another area Done handles, including running duct to the outside in kitchens that currently have only recirculating hoods.

Whole-House and Attic Ventilation

Whole-house fans pull air through open windows and exhaust it through the attic, cooling the home rapidly during Colorado’s pleasant evenings and mornings without running the air conditioner. They’re well-suited to the Front Range’s climate, where summer nights cool down significantly after hot afternoons — a much wider day-night temperature swing than in more humid climates. Done installs and services whole-house fans as part of a broader approach to home comfort and energy efficiency.

Why Ventilation and Indoor Air Quality Go Hand in Hand

Ventilation is one pillar of indoor air quality, but it works best in combination with proper filtration and, where appropriate, air purification. Done takes a whole-home approach to air quality — we can assess how your home currently exchanges air, where pollutants are coming from, and what combination of ventilation, filtration, and purification will make the most meaningful difference for your household. For wildfire smoke season, allergy sufferers, or homes with tight construction, this kind of assessment is worth doing.
