Furnace and AC Service in Denver, CO

Denver proper is the widest range of homes we work in anywhere. Capitol Hill and Wash Park bring 1890s to 1920s brick with boilers and radiators, Park Hill and Harvey Park are 1950s ranches with original ducts, Stapleton and Green Valley Ranch are 2000s builds on first replacements, and infill in Berkeley and Sloan’s Lake wants mini-splits. Boiler replacement, ductless retrofits and high-efficiency furnace swaps are the common jobs, and every one needs a Denver mechanical permit, which we pull.

QUICK FACTS

HVAC in Denver at a glance.

At 5,280 ft a gas furnace delivers roughly 79% of its rated output, so every system we install in Denver is sized and adjusted for altitude. Front Range furnaces run six to seven months a year, which is why most Denver homeowners choose 96% two-stage equipment or a cold-climate heat pump. Denver requires a mechanical permit and inspection on every furnace and AC replacement; we pull it and schedule it. Denver is served from our Denver office at 1900 S Quince St Unit B with same-day appointments and no trip charges.

QUESTION

Does altitude change which furnace I need in Denver?

Yes. Gas furnaces lose about 4% of output per 1,000 feet, so at 5,280 ft a furnace delivers roughly 79% of its rated heat. We size and adjust for that; installers who skip it leave Denver homes short on heat.

Lower elevation also means higher summer cooling loads, so AC sizing matters as much as furnace sizing.

QUESTION

Which rebates can Denver homeowners get?

Denver is on Xcel Energy for gas and electric, so Xcel furnace, AC and heat pump rebates apply. EMS files the Xcel paperwork for you.

QUESTION

Do you offer same-day furnace repair in Denver?

Yes. Denver is on our daily routes from the Denver office, same-day appointments are available, and no-heat calls get a technician on site within 4 hours. No trip charges.

Trucks are stocked with ignitors, flame sensors, capacitors and blower motors for the brands common in Denver homes, so 91% of repairs are finished on the first visit.
