About This Area

Heating and Cooling in Commerce City Homes

Commerce City is the lowest of the areas we cover, at 5,191 feet. It incorporated as a town in 1952 and the housing splits in two: an older core around the original town, and much newer development to the north. Which half a house sits in usually decides what we find when the cabinet comes off.

  • 5,191 feet above sea level
  • North Metro
  • Emergency line answered around the clock
  • Free estimates on new systems, in writing

Altitude is the part that catches people out. At 5,191 feet a gas furnace or boiler cannot run at the rating printed on its plate, and an air conditioner loses capacity to the thin air as well. Equipment that would be correctly sized in a lower city is not correctly sized here, so anything we quote for a Commerce City home is worked out against that rather than against a chart.

Why Altitude Matters Here

Sizing a Furnace or AC for Commerce City at 5,191 Feet

A gas furnace or boiler cannot be installed at its sea level rating anywhere in the Denver metro. Above 2,000 feet there is less oxygen to burn with, so input has to be derated by roughly 4% for every 1,000 feet, and at 5,191 feet that is about 12.8% off the plate in Commerce City.

  • Incomplete Combustion

    A gas furnace set to its sea level input burns more fuel than the thin air here can support, so it never fully burns.

  • More Carbon Monoxide

    Burning rich is what produces carbon monoxide, which makes the derate a safety step on every gas furnace and boiler.

  • Reduced Heating Output

    The plate rating was measured at sea level, so an appliance left uncorrected delivers less heat than the label claims.

Sizing for altitude is not an upsell, it is the arithmetic behind the quote. A furnace worked out from a sea level chart falls short on the coldest week of a Commerce City winter, and an air conditioner sized the same way works harder for less. Estimates on a new system are free and given in writing, so the numbers behind a recommendation are yours to check.
