Where most jobs landed
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.
Goodleap financing is available, including 100% financing, no-interest options and terms up to 15 years.
On-site estimate
What we inspect at your home
A few furnace replacement factors we will inspect on-site:
- Accessibility. Furnaces in an easy-to-reach garage or closet cost less than attic units. We offer a discount for easily accessible locations.
- Gas and electrical connections. We check your existing gas and electrical connections, and worn parts may need replacing for safety.
- Exhaust and venting. If your exhaust is older Asbestos Transite pipe, we may need to remove it and install new double-wall venting through the roof with a new cap, collar, and flashing.
- High-efficiency upgrade. Condensing furnaces need a condensate drain and watertight venting as part of an upgrade.
As part of any Thomson AC visit, you will get a full written report and an on-site estimate before any work begins, so there are no surprises.

Repair or replace
Repair or replace your furnace?
Not every furnace that acts up needs to be replaced. We’ll tell you honestly which way makes sense for your home.
Repair usually makes sense when
- The furnace is fairly young and has been reliable.
- The problem is a single part, like an igniter, flame sensor, or blower motor.
- The rest of the system checks out safely.
Replacement usually makes sense when
- The furnace is 15 to 20 years old or more, since most furnaces last about that long.
- Repairs are getting frequent or expensive. When a repair costs more than about a third of a new unit, replacement usually wins.
- Some rooms never get warm, the furnace short-cycles, or energy bills keep rising despite normal use.
- The burner flame is yellow instead of blue, or there’s a cracked heat exchanger or carbon monoxide concern. This is a safety issue: if you smell gas, leave the house and contact your gas provider.
Our tech shows you what we found and lays out both options before you decide. No pressure either way.
Not every heater needs replacing. The right call comes down to age, repair cost, and reliability. Repeated breakdowns are the clearest signal. Two or more service calls in a season usually means a replacement saves money long term.
Time to replace?
Signs it is time for a new furnace
- The furnace is 15 to 20 years old or more
- Repairs are getting frequent, two or more service calls in a season
- Some rooms never get warm, or the furnace short-cycles
- Energy bills keep rising despite normal use
- A yellow burner flame, a cracked heat exchanger or a carbon monoxide concern
Efficiency
High-efficiency furnaces: more comfort, lower bills
AFUE (Annual Fuel Utilization Efficiency) is the gas-mileage rating for a furnace. It is the percentage of fuel converted directly to heat. An 80% AFUE furnace turns 8 of every 10 units of fuel into heat and the rest is waste. The higher the AFUE, the lower your gas bill, and today’s best furnaces reach 95 to 96% or more.
The trade-off with high-efficiency condensing furnaces is moisture, a byproduct of complete combustion. Most homes need a condensate drain added and the flue venting upgraded to be watertight. In a standard upgrade, Thomson will include new venting and a condensation removal system: a pump, a drain pan for attic units, and a condensate line to an approved location.
Thinking about a heat pump instead? In our mild coastal weather, one system can heat in winter and cool in summer. See replacing a gas furnace with a heat pump.
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.
Install day
What is included in our furnace replacement service
Changing out a home furnace is detailed work. Here is what a standard Thomson furnace change-out includes:
- Pull the city permit and schedule the inspection
- Remove, haul away, and recycle the existing furnace
- Install the new furnace in the existing location
- Mount a new thermostat in the existing or an approved location
- Run new low-voltage control wiring as needed
- Install a filter base for easy filter changes, plus two filters
- Wire the electrical pigtail to your existing high-voltage outlet
- Connect a flexible gas line with a ball valve for easy shutoff
- Install a sediment trap with drip-leg and clean-out on the gas supply
- Run and securely connect exhaust vent piping
- Seal and insulate all sheet-metal and equipment connections
- Test all equipment for proper heat and fan operation
We pull permits on furnace replacements, so the work is inspected and on record with the city.
Warranty
Our warranty: 10 to 12 year parts, 5 year labor
Most furnaces include a 10-year parts warranty, and if you choose a Daikin it is a 12-year parts warranty. With documented maintenance, meaning you keep up your filter changes, the manufacturer replaces failed parts free, though you would normally still pay labor. That is why Thomson adds a 5-year labor warranty on every central furnace we install, and we give it to you in writing.

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.
Keep existing ductwork. If your current ducts are in good shape, reusing them cuts costs significantly.
Financing. Many homeowners use financing such as Goodleap when they qualify. Ask Thomson AC what options are available on your quote.

Furnace replacement and cost questions
Furnace replacement FAQs
How long does it take to replace a furnace?
Most furnace replacements take 4 to 8 hours. A standard change-out in an accessible location is often done in a single day. High-efficiency upgrades or venting changes can add time.
Should I repair or replace my furnace?
If your furnace is fairly young and the problem is one part, repair usually makes sense. If it's 15 to 20 years old, needs repeated repairs, or a repair would cost more than about a third of a new unit, replacement is usually the better spend. We'll show you both options before you decide.
Should I replace a 20-year-old furnace?
Usually, yes. Most furnaces last 15 to 20 years, and by 20 a furnace is less efficient and more failure-prone. If a repair costs more than about a third of a new unit, replacement is the smarter spend.
Do you pull permits for furnace replacement in Huntington Beach?
Yes. We pull permits on furnace replacements, so the installation is inspected and on record with the city.
Can I finance a new furnace?
Yes. We offer financing through Goodleap, including 100% financing, no-interest options, and terms up to 15 years. We can go over it with you during your free estimate.
Does homeowners insurance cover furnace replacement?
Typically only when the failure results from a covered peril, like a fire, not from normal age or wear. Check your policy, since routine end-of-life replacement is generally not covered.
Can a heat pump replace my furnace?
Often, yes. In Southern California's mild climate, a heat pump can handle both heating and cooling efficiently. We can compare a high-efficiency furnace against a heat pump for your home during the estimate.
How often does a furnace need to be replaced?
About every 15 to 20 years with regular maintenance. Annual tune-ups and routine filter changes extend a furnace's life and keep efficiency up.
When should I replace my heating system?
Consider heating replacement when your system is near the end of its service life, needs repeated repairs, has uneven heat, or no longer meets your comfort needs. Thomson AC can inspect it and explain repair versus replacement clearly.
What is the difference between heating replacement and furnace replacement?
Furnace replacement means replacing a gas furnace. Heating replacement is broader and can include a furnace, heat pump, or another heating system. We compare options based on your home's needs and existing equipment as part of our heating services in Huntington Beach .
How much does a furnace replacement cost in Huntington Beach?
On our recent furnace-only replacements for Huntington Beach and nearby Orange County and Long Beach homes, most jobs landed between $4,500 and $5,700, and the typical job came in at about $5,100. Your price comes from a free in-home estimate.
What moves the price of a new furnace?
Furnace size and efficiency, venting or flue pipe that needs to be replaced to meet code, the equipment brand you choose, and where the furnace sits (closet, garage or attic) and how easy it is to reach.
Is the estimate free?
Yes. Estimates on furnace and system replacements are free. We come out, look at what you have, and give you a written estimate before any work starts. Repairs start with a paid diagnostic visit.
Will my new furnace work differently than my old one?
Often a little. A newer, higher-efficiency furnace can run quieter and longer at a lower output. We walk you through the new thermostat and filter changes on install day.
