Free in-home replacement quote on gas furnaces, electric furnaces, and high-efficiency condensing units (95–98% AFUE) across Northern Virginia, Maryland, and Washington DC. Same-week installation available for emergency winter failures. $0 down financing through Home Depot and Lowe's.
Furnace replacement in the DMV ranges $5,500 to $14,000 installed. Standard 80% AFUE gas furnaces start around $5,500. High-efficiency 95-98% AFUE condensing units run $8,000 to $13,000. Electric furnaces typically run $4,000 to $8,000. HVAC-DMV handles same-week installation for emergency winter failures across Northern Virginia, Maryland, and Washington DC.
The biggest decision in furnace replacement is the efficiency tier. An 80% AFUE furnace converts 80% of fuel energy to heat and loses 20% out the flue. A 95-98% AFUE condensing furnace recovers nearly all that lost heat by condensing exhaust gases — gaining 15-18% in efficiency. In the DMV climate, that's typically $300-600 per year in heating savings. Condensing furnaces pay back the upfront difference in 4-7 years and run more quietly with better temperature consistency.
This is a math question, not an opinion. If both systems are over 10 years old, replacing them together as a matched system delivers (1) better efficiency than mismatched components, (2) a single coordinated installation rather than two separate jobs, and (3) a unified warranty across all parts. If your AC is newer than 8 years and in good condition, replacing just the furnace makes sense. HVAC-DMV's free in-home quote prices both scenarios so you can compare.
Worth considering. State and utility rebate programs (Dominion Energy, Pepco, EmPOWER Maryland, BGE) provide significant savings on qualifying heat pumps — savings not typically available on gas furnaces. For homeowners where the AC is also aging, replacing both with a heat pump system is often the most efficient long-term move. If only the furnace has failed and the AC is newer, a dual-fuel setup (heat pump for primary heating and cooling, existing gas furnace as backup for the coldest days) captures most efficiency benefits at lower upfront cost. HVAC-DMV runs all three scenarios in every quote.

High-efficiency 95-98% AFUE condensing gas furnaces range $8,000 to $13,000. Electric furnaces run $4,000 to $8,000. Pricing depends on BTU sizing, venting requirements, and whether new gas lines or electrical work is needed.
Yes. HVAC-DMV handles emergency winter furnace failures with same-week installation across Northern Virginia, Maryland, and DC. If you have no heat, call (571) 704-7848 immediately — we keep common units in stock for emergency replacement.
Depends on your situation. Heat pumps qualify for state and utility rebate programs through Dominion Energy, Pepco, EmPOWER Maryland, and BGE, which can significantly offset the higher upfront cost. If your AC is also aging, replacing both with a heat pump system is usually the right financial call. If your AC is newer and only the furnace has failed, a dual-fuel heat pump + existing AC setup captures most benefits at lower cost. HVAC-DMV prices both paths.
AFUE measures how much of the fuel energy actually becomes heat in your home. An 80% AFUE furnace loses 20% of its energy through the flue. A 95-98% AFUE condensing furnace recovers most of that lost heat by condensing exhaust gases. In the DMV, condensing furnaces typically save $300-600 per year on heating bills, paying back the upfront difference in 4-7 years.
Most furnace replacements are completed in a single day. Complex installations (new venting, gas line modifications, complete system replacement with AC) may take 2 days.
Yes. HVAC-DMV installs natural gas furnaces, propane furnaces, electric furnaces, and dual-fuel systems (heat pump + gas backup) across Northern Virginia, Maryland, and Washington DC.
