How much does furnace repair cost in Virginia?

Virginia has no set price for furnace repair. Licensed HVAC businesses set their own rates, and the bill depends mostly on which part failed. A thermostat setting or a clogged filter costs little beyond the visit; a failed control board, blower motor or gas valve is a part plus the labour to fit it. The way to pay a fair price is to know what makes up the bill, get the diagnosis and the price in writing before work starts, and compare like with like.

What makes up a furnace repair bill

The service call. Most businesses charge to come out and diagnose the problem. Ask what it covers, whether it changes on nights and weekends, and whether it comes off the repair if you go ahead.

The cause. Some causes are cheap because they are simple. Bryant's first checks are the thermostat, the air filter, the furnace's power switch and circuit breaker, and whether supply registers and return grilles are open,^[2] and Carrier says the most common cause of a furnace blowing cold air is a thermostat fan set to "On" instead of "Auto".^[1] If that is all it turns out to be, the bill should be the service call. For why a furnace stops heating, see why a furnace blows cold air.

The part. When a component has failed, the price follows the part. The ones Carrier and Bryant name most often when a furnace will not heat are flame sensors, limit switches, pilot assemblies and thermocouples, gas valves, blower motors and the furnace control board.^[1][2] Ask for the part and the labour as separate lines, and whether the part is still under the manufacturer's warranty.

Labour and access. A furnace in an open basement is quicker to work on than one in a crawl space or a tight attic, and a part that has to be ordered can mean a second trip. Ask whether a return visit is charged.

Fuel and equipment. A gas or oil furnace has combustion work that an electric one does not. ENERGY STAR's heating check covers checking all gas (or oil) connections, gas pressure, burner combustion and the heat exchanger.^[4]

Age. Parts for an older furnace can be harder to find, and a large repair on an old unit raises the replace-or-repair question. Lennox's rule of thumb is that it is best to replace a furnace if a repair costs more than half the cost of a new one, and it says the "average lifespan of furnaces is 15-20 years."^[3] Read should I repair or replace my furnace before approving a big repair on an old one.

Getting a price you can compare

ENERGY STAR's advice is to get written, itemized estimates and compare cost, energy efficiency and warranties.^[5] For a repair, ask each business for:

• the diagnosis in plain words, and what they tested to reach it;
• the part, the labour and any trip or after-hours charge, listed separately;
• whether the service call fee comes off the repair;
• the warranty on the part and on their work;
• whether the furnace is safe to run until the repair is done.

Licence. Under Virginia law no person may engage in, or offer to engage in, contracting work in Virginia without a licence,^[7] and under the Code's definitions, Class C contractors are those whose single contract or project is over $1,000 but less than $30,000, or whose total work in any 12-month period is less than $250,000.^[6] For HVAC, the Board must require a master tradesman licence as a condition of licensing an HVAC contractor,^[6] and the person doing the work must hold a tradesman licence unless working under the supervision of a tradesman licensed in that specialty.^[8] See does an HVAC technician need a licence in Virginia.

Contract. Virginia's Board for Contractors requires a legible written contract for residential contracting, signed by both sides before work starts or payment is accepted, but excludes those who do routine maintenance or service contracts.^[9] The rule defines residential contracting as "construction, removal, repair, or improvements to single-family or multiple-family residential buildings," so the rule covers repair work, not only replacements.^[9] The contract must include a statement of the total cost, the contractor's licence number and class, and a statement that any change to the cost, materials, work or completion date must be in writing and signed by all parties.^[9]

Help paying for heating repairs in Virginia

When we checked on 26 October 2026, the Virginia Department of Social Services' Crisis Assistance listed heating equipment repair or replacement for households with a heating emergency, which it describes as no heat, a cut-off notice or unsafe equipment.^[10] Households must have a heating or cooling expense and gross monthly income at or below 150% of the federal poverty level,^[10] and the application window for equipment help runs from November 1 to March 15.^[10] Applications go through CommonHelp, a paper form, or by phone at 855-635-4370.^[10]

DHCD's Weatherization Assistance Program works through local nonprofit providers, and its common measures include repairing and replacing inefficient or unsafe heating and cooling systems.^[12] Contact the provider for the area where the home is.

ENERGY STAR's advice is to maintain your equipment to prevent future problems and unwanted costs, with a contractor check-up of the heating system each fall.^[4] See how much an HVAC tune-up costs in Virginia and how to keep a heating system from failing in winter.

When to call a licensed pro

Two signs are emergencies, not a reason to shop for a price. If you smell gas, Columbia Gas of Virginia's instruction is to "go outside and call 911 and then call us at 1-800-544-5606 (24/7)."^[11] If another company supplies your gas, use its emergency number. If a carbon monoxide alarm sounds or anyone has symptoms of carbon monoxide poisoning, Columbia Gas says to "leave the area to get to fresh air and immediately call 911."^[11]

Call for a diagnosis rather than waiting for a better price when:

• You see soot around the furnace. Carrier's advice for soot around the furnace is to turn off the system immediately and contact a professional.^[1] A gas smell is different: leave the house first and call from outside, as above.
• The breaker trips each time the furnace runs.
• There is no heat after the thermostat, filter and power switch are checked, and the weather is cold enough for pipes to freeze.
