Calculated sizing, altitude-correct setup and a spotless install. Free estimates and financing for Golden homeowners.
Planning a new furnace in Golden? Start with what is already in the house. Historic homes downtown, mid-century homes near the Mines campus, and foothill properties at noticeably higher elevation. Golden sits at the base of the foothills, so a home downtown and a home on the hillside a few miles away can face very different conditions. Our free estimates include a room-by-room load calculation, a duct review and clear options from standard to premium.
Higher foothill homes run longer heating seasons, and furnace setup and venting matter more where wind gusts are strong.
Every installation starts with a Manual J load calculation and a look at your ductwork, because the wrong size furnace is the most common reason a new system disappoints. We then present written options, from efficient single-stage to modulating premium equipment. Installation includes permits where required, haul-away, new venting and drain work, commissioning and a walk-through.
At about 5,700 feet in town, higher in the foothills, altitude setup is not optional. A new furnace that is not configured for elevation can run hot and wear early. We set and verify every Golden install against the manufacturer's altitude guidance before we leave.
