How Much Does Furnace Replacement Cost in Fort Worth?

A furnace-only replacement from Family First Comfort in Fort Worth typically costs $3,000 – $6,000 installed, depending mostly on the furnace's size. That range is a starting point for your budget, not a quote for your home. The final price depends on the fuel type, the capacity your home actually needs, the efficiency you choose, how easy the equipment is to reach, and whether the job is really furnace-only.

We start every furnace project the same way: look at the home, check the existing setup, and tell you plainly if a repair makes more sense than a replacement.

Furnace-only versus a full system

Make sure you're comparing the same kind of job. A furnace-only quote is different from a full heating and cooling replacement, which can include a new air conditioner, indoor coil, and refrigerant work. A full system from us typically runs $8,500 – $15,000+ installed.

What changes the installed price

The equipment and your home's existing setup matter more than any citywide average. Sizing should come from your home's actual heating load, not from whatever size the old unit was. A furnace that's too big wastes money and short-cycles, and one that's too small struggles on the coldest nights.

• Fuel type: a gas furnace may need gas line and venting work, while an electric furnace may need electrical circuit work and usually costs less up front.
• Capacity: square footage is only part of sizing. Insulation, windows, layout, ceiling height, and duct condition all affect how much heat your home needs.
• Access: a tight attic install takes more labor than a furnace in an open utility closet.
• Ductwork and connections: duct changes, loose connections, failed supports, venting changes, electrical upgrades, or moving the equipment add materials and labor.

Efficiency and incentives

AFUE, or Annual Fuel Utilization Efficiency, tells you how much of the fuel a furnace burns turns into heat for your home. A higher AFUE wastes less gas, but higher-efficiency furnaces usually cost more up front. The right choice depends on your budget, how much you heat your home, and what fits the space.

Be careful with older articles about tax credits. The federal 25C credit doesn't apply to equipment placed in service after December 31, 2025, so it won't lower the cost of a 2026 installation. Atmos Energy Mid-Tex customers may qualify for a rebate on a high-efficiency gas furnace, though.

When replacement makes more sense than repair

A furnace problem doesn't automatically mean you need a new furnace. We look at the unit's condition, the repair it needs, how reliable it's been, and how long you plan to stay in the home.

With good maintenance, furnaces often last 15 to 20 years. Once a unit is in that range, repeated repairs can cost more than they're worth, especially if breakdowns keep coming back or some rooms never get warm. Tell us about past repairs, uneven rooms, odd noises or behavior, and any duct concerns. Those details help separate a fixable problem from a furnace near the end of its life.

Fort Worth permits

The City of Fort Worth requires a mechanical permit when heating and cooling equipment or ductwork is replaced, moved, or repaired, and the work has to be done by a properly licensed contractor. When we install your furnace, we pull the permit and handle the inspection, so it's part of the job instead of a task on your list.

What a good quote should include

A written estimate should turn a broad price range into a clear project. Look for the fuel type, furnace capacity, efficiency rating, exactly what's included, any duct, venting, or electrical work, who handles the permit, and what's excluded.

Our process includes an assessment, a ductwork review, a walkthrough of the installation, and a full system test before we finish. Every installation includes a 1-year labor warranty you can extend to 10 years, which covers our own work on things like air leaks, loose duct connections, ducts that pull away from the plenum, and failed support straps. We also offer financing, including a 0% option for 12 months on qualifying projects.

How to get a more useful estimate

Before you call, note your furnace's fuel type, rough age, recent repairs, and any comfort problems. Let us know if it's in the attic, if it's hard to reach, and if you've noticed duct issues. Every detail helps us define the job before installation day. We offer free estimates with no pressure. Call (817) 935-8540 to talk about a new furnace for your Fort Worth home.
