Englewood’s older neighborhoods are full of character. The city’s median home was built in 1964, and about two thirds of its homes predate 1980, so many furnaces here are working with ductwork and venting that are decades older than the equipment.

At about 5,371 feet a gas furnace loses roughly 13.5% of its rated output, about 4% for every 1,000 feet above 2,000. That is why the residential building code requires a new furnace to be sized from a load calculation of the house, not copied from the old nameplate, and why the burner has to be set up for the altitude.

A furnace replacement in Englewood is permitted through the City of Englewood’s Building Division, not Arapahoe County. We handle the permit and the inspection, and our furnace inspections include a carbon monoxide test and a gas leak test. MoJo Home Services is family-owned and has served Englewood since 2009.
