QUESTION

Does altitude change which furnace I need in Lafayette?

Yes. Gas furnaces lose about 4% of output per 1,000 feet, so at 5,240 ft a furnace delivers roughly 79% of its rated heat. We size and adjust for that; installers who skip it leave Lafayette 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 Lafayette homeowners get?

Lafayette 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 Lafayette?

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