QUESTION

Does altitude change which furnace I need in Windsor?

Yes. Gas furnaces lose about 4% of output per 1,000 feet, so at 4,800 ft a furnace delivers roughly 81% of its rated heat. We size and adjust for that; installers who skip it leave Windsor 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 Windsor homeowners get?

In Windsor, furnace rebates come from the gas utility (Xcel Energy) and AC and heat pump rebates from the electric utility (Xcel or Poudre Valley REA). We confirm your providers and current amounts on your estimate and file the paperwork.

QUESTION

Do you offer same-day furnace repair in Windsor?

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