HVAC Services in Denver
Trusted HVAC services for Denver homeowners. Same-day repair, expert installation, and 24/7 emergency response across the Mile High City.
Trusted HVAC Service in Denver
Denver’s high altitude, dry climate, and dramatic temperature swings put unique demands on home HVAC systems. From January cold snaps that drop below zero to July heat waves pushing 95°F+, your furnace and AC need to handle it all.
MrFixer Heating & Cooling has served Denver for over a decade. Our certified technicians live and work here — we know exactly how altitude, humidity, and seasonal extremes affect HVAC performance. Whether you live in a Victorian in Capitol Hill, a modern condo in LoDo, or a single-family home in Park Hill, we deliver fast, honest, professional service.
Local Climate Note
Mile High elevation (5,280 ft) means HVAC equipment derates and combustion needs altitude tuning. Dry winter air drops indoor RH below 15% — humidifiers strongly recommended.

Learn moreFAQs about HVAC in Denver
Common questions from Denver homeowners.
Do you serve all of Denver?
Yes — we cover every Denver ZIP code from Stapleton to Sloan's Lake, Capitol Hill to Park Hill, and everywhere in between. Same-day service is typical across the city.
How does Denver's altitude affect HVAC?
At 5,280 ft, gas furnaces lose ~4% efficiency per 1,000 ft above sea level. Equipment must be sized larger and combustion adjusted for thinner air. We always commission per Colorado altitude specs.
Do you handle older Denver homes?
Absolutely — we specialize in Victorian-era and mid-century Denver homes. We've worked on homes in Curtis Park, Five Points, and Capitol Hill that are 100+ years old.
Can I get a quote for AC installation in Denver?
Yes — we offer free in-home estimates with no surprise costs. Pricing depends on home size, SEER rating, and ductwork condition, so we always assess on-site.
Are you licensed in Denver?
Yes — fully licensed by the City and County of Denver, EPA Section 608 certified, fully insured and bonded. We pull all required permits for installations.
