QUESTION

Does altitude change which furnace I need in Westminster?

Yes. Gas furnaces lose about 4% of output per 1,000 feet, so at 5,380 ft a furnace delivers roughly 78% of its rated heat. We size and adjust for that; installers who skip it leave Westminster 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 Westminster homeowners get?

Westminster 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 Westminster?

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