Furnace and AC Service in Commerce City, CO

Reunion and Buffalo Run brought thousands of 2000s homes to Commerce City, and their original furnaces and ACs are reaching end of life now, typically an 80,000 BTU furnace and a 3-ton AC. Older homes near Derby and the historic core need venting and duct corrections with a replacement, and Turnberry and The Villages at Buffalo Run are mostly in warranty-period service.

QUESTION

Does altitude change which furnace I need in Commerce City?

Yes. Gas furnaces lose about 4% of output per 1,000 feet, so at 5,160 ft a furnace delivers roughly 79% of its rated heat. We size and adjust for that; installers who skip it leave Commerce City 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 Commerce City homeowners get?

Commerce City 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 Commerce City?

Yes. Commerce City 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 Commerce City homes, so 91% of repairs are finished on the first visit.
