Most homeowners can expect to pay $3,000 to $12,000 to replace a heater in 2026. A basic gas furnace runs $3,000 to $6,000 installed. A heat pump runs $4,500 to $8,000. High-efficiency systems that need new ductwork or electrical work reach $8,000 to $12,000 or more.
These are general market price ranges, not Thomson quotes. Your price depends on your home, and we give you a free written estimate before any work starts.
What Thomson Typically Charges for a Furnace Replacement
These are real numbers from furnace-only replacements we completed and invoiced for Huntington Beach and nearby Orange County and Long Beach homes between October 2025 and July 2026 (15 jobs).
What moves the price:
- Furnace size and efficiency (a standard 80% furnace vs. a higher-efficiency model)
- Venting or flue pipe that needs to be replaced to meet code
- The equipment brand you choose
- Where the furnace sits (closet, garage or attic) and how easy it is to reach
Every replacement includes the permit, which we pull for you, and a 5-year labor warranty in writing. Financing is available through Goodleap for qualified homeowners.
Prices are before tax and are for replacing the furnace only. Adding air conditioning or switching to a heat pump is a bigger job and is quoted separately. Your price comes from a free on-site estimate.
Equipment Costs: What the Heater Itself Runs
A furnace (gas heater) costs between $2,000 and $5,500 for the unit alone. Heat pumps run $2,500 to $6,000. Premium models with high AFUE ratings cost more.
AFUE stands for Annual Fuel Utilization Efficiency. According to the U.S. Department of Energy, a higher AFUE rating means more heat from the same fuel. A 95% AFUE furnace costs more than an 80% model, but it saves money over 15 to 20 years.
In Southern California, heat pumps are increasingly popular. They provide heating and cooling in one system. Upfront cost is higher, but one system does double duty.
Brand matters too. Lennox, Carrier, and Trane systems cost more than budget brands but hold value and reliability. See our furnace replacement options for current equipment.
New Heater Installation Cost in 2026
Installation cost for home heating is the part most homeowners underestimate. The unit price is only half the picture.
A standard furnace installation in Southern California runs $3,000 to $6,000 all in. That covers the equipment, labor, removal of the old unit, and basic testing.
A new gas heater installation with a high-efficiency furnace runs $5,000 to $8,500. The jump comes from the better equipment and the venting it requires.
Your final installation cost depends on three things: the equipment you pick, your existing ductwork, and any electrical or gas line work the job needs.
HVAC Installation and Labor: The Hidden Cost
When it comes to HVAC installation cost, the labor runs $800 to $2,500 depending on complexity. Simple swaps cost less. Major ductwork changes or relocations cost more.
If your home needs new ductwork, add $1,000 to $5,000. Electrical upgrades or gas line work push costs higher again.
Pro contractors charge for inspection, equipment removal, disposal, and testing. Read every line item before you sign.
Emergency or rush service on nights, weekends, and holidays adds 50% or more to labor. Plan ahead when you can.

Repair or Replace: Which Makes Sense?
Not every heater needs replacing. The right call comes down to age, repair cost, and reliability.
Ready to book? Call us or text us at (562) 201-3014 for a Free Estimate. Next steps: furnace replacement or furnace repair.
Repair makes sense when your unit is under 10 years old and the fix costs less than $500. Most heater repairs land between $150 and $800.
Replace when the repair tops half the cost of a new system, or when the unit is 15 years or older. A cracked heat exchanger alone can run $1,000 or more.
Repeated breakdowns are the clearest signal. Two or more service calls in a season usually means a replacement saves money long term.
Ways to Lower Your Replacement Cost
Rebates and incentives. The federal heat pump tax credit (25C) ended for equipment placed in service after December 31, 2025. California utility rebates may still apply, and programs change, so ask us which ones fit your system. You can also check current programs from the U.S. Department of Energy.
Timing. Replace during spring or fall, not winter. Contractors have more availability and lower service-call premiums.
Keep existing ductwork. If your current ducts are in good shape, reusing them cuts costs significantly.
Compare quotes. Get three estimates from licensed contractors. Pricing varies with equipment choice and installation scope.
Financing. Many homeowners use financing such as Goodleap when they qualify. Ask Thomson AC what options are available on your quote.
Getting an Accurate Quote for Your Home
The only way to know your exact cost is a professional inspection and quote. An experienced contractor evaluates your current system, ductwork, electrical setup, and heating service needs.
They recommend equipment that matches your budget and comfort goals. They itemize labor and materials so you see where the money goes.
Thomson Air Conditioning provides transparent quotes with no surprises. We discuss equipment options, explain the ROI of higher-efficiency models, and outline what installation includes.
