Furnace and AC Service in Littleton, CO

Littleton covers everything from 1950s downtown bungalows and Bow Mar ranches to 1990s two-stories in Ken Caryl, Roxborough and Columbine. Original furnaces in the west Littleton subdivisions are now at 25 to 30 years, and Ken Caryl and Columbine homes often need a return-air fix with a replacement. Downtown Littleton brings small closets, old venting and the occasional boiler.

QUESTION

Does altitude change which furnace I need in Littleton?

Yes. Gas furnaces lose about 4% of output per 1,000 feet, so at 5,400 ft a furnace delivers roughly 78% of its rated heat. We size and adjust for that; installers who skip it leave Littleton 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 Littleton homeowners get?

Littleton 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 Littleton?

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