When your old furnace finally gives out—or you're tired of rising bills and uneven heat—a new system is one of the most impactful upgrades you can make to a DC home. We install high-AFUE gas and electric furnaces sized correctly for your space, so you get steady, reliable warmth from the rowhouses of Capitol Hill to the detached homes of Chevy Chase. Every installation is handled by our team and pulled under a permit by a master-licensed contractor, so the work is done right and to DC code.
Furnace replacement isn't just about swapping a box in the basement. We take time to evaluate your existing ductwork, venting, and combustion-air supply, because a system that's oversized or improperly vented wastes energy and can create safety problems. That's especially true in the District's older, tightly sealed brick homes, where venting and fresh-air requirements need careful attention. Our goal is a system that runs efficiently, quietly, and safely for the long haul.
We also believe in giving you honest options rather than pushing the most expensive equipment. If you're heating with aging oil or gas equipment, we'll walk you through whether a high-efficiency furnace or a heat-pump conversion makes more sense for your home and budget—including the federal and local rebates and tax credits that can meaningfully lower your out-of-pocket cost.
