QUICK FACTS

HVAC in Golden at a glance.

At 5,675 ft a gas furnace delivers roughly 77% of its rated output, so every system we install in Golden is sized and adjusted for altitude. Front Range furnaces run six to seven months a year, which is why most Golden homeowners choose 96% two-stage equipment or a cold-climate heat pump. Foothills homes above 7,000 ft need equipment derated and often a backup heat source. Golden 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 Golden?

Yes. Gas furnaces lose about 4% of output per 1,000 feet, so at 5,675 ft a furnace delivers roughly 77% of its rated heat. We size and adjust for that; installers who skip it leave Golden 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 Golden homeowners get?

Golden 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 Golden?

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