About This Area
Heating and Cooling in Centennial Homes
Centennial is the youngest city in the metro on paper and one of the older ones in practice. It incorporated in 2001, the largest incorporation of its kind in the country at the time, but most of its housing went up through the 1970s, 1980s and 1990s while the area was still unincorporated Arapahoe County. At 5,722 feet it sits more than 400 feet above Denver.

Altitude is the part that catches people out. At 5,722 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 Centennial home is worked out against that rather than against a chart.

Why Altitude Matters Here
Sizing a Furnace or AC for Centennial at 5,722 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 5,722 feet that is about 14.9% off the plate in Centennial.
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 Centennial 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.
