Calculated sizing, altitude-correct setup and a spotless install. Free estimates and financing for Castle Pines homeowners.
Castle Pines sits on high ground between Lone Tree and Castle Rock, above most of the metro, with some of the area's largest custom homes. Custom luxury homes in the gated Village at Castle Pines, 1990s and 2000s homes in the city's established neighborhoods, and newer construction in The Canyons. For many Castle Pines homeowners that means a furnace replacement is coming, either by plan or by surprise. Besties HVAC Solutions installs high-efficiency furnaces that are sized to the home, set up for altitude and installed with the care a fine home deserves.
Large custom homes here may combine forced air with radiant floors or boilers, so we diagnose the whole heating plant, not one box.
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.
Castle Pines sits at about 6,200 to 6,400 feet. Gas furnaces lose capacity with elevation, and many manufacturers specify derating or high-altitude kits. We follow those instructions and verify them on startup, which protects efficiency, the heat exchanger and your warranty.
