Furnace Repair in Denver

Expert Furnace Repair and Heating Services in Denver

When winter fronts roll off the Rockies, a reliable furnace isn’t just optional; it’s necessary for comfort and safety. Denver’s high elevation and dry air place unique demands on heating systems, from proper gas derating and combustion tuning to humidification that protects wood floors and sinuses. Done’s licensed technicians repair all major furnace brands across the city—from historic brick homes in Park Hill and the Highlands to newer builds in Green Valley Ranch—arriving in well-stocked trucks and providing clear, upfront pricing before work begins.

Strange smells, frequent cycling, or rising gas bills are early warning signs that your furnace needs service. We start with a full diagnostic, including static pressure and airflow tests, flame signal and ignition checks, and heat exchanger inspections to catch cracks before they become carbon monoxide hazards. For high-efficiency units, we clear blocked condensate traps, thaw and protect exterior drains, and verify venting sized for altitude. If rooms heat unevenly, we balance ducts, add returns where needed, and tune blower speeds so comfort reaches every level, including finished basements.

Dry winters can make a working furnace feel less comfortable. We service and calibrate whole-home humidifiers, clean burners and sensors, and replace worn igniters and inducer motors to restore dependable, quiet heat. If your furnace is near the end of its life, we’ll stabilize it with honest repairs and present right-sized replacement options locally tailored to your home, such as cold-climate heat pumps, so you can decide with confidence.

With Done, you get one coordinated partner for heating, cooling, plumbing, and electrical. Explore some of our other service offerings in Denver:
