Will a new furnace lower my bill?
Usually somewhat, since a new furnace wastes less fuel than a 20 year old one. Fresno's heating season is short, so the savings are modest. The larger reason to replace is reliability and safety.
Furnace Replacement and Installation in Fresno, CA
A new gas furnace in Fresno typically costs about $4,200 to $6,000 installed for common 60,000 to 100,000 BTU sizes, depending on efficiency, venting and ductwork. We size the furnace for your home, handle the permit, and install it safely.
Because Fresno has a short, mild heating season, we also walk you through the heat pump option so you can choose with all the facts. Emergency service is available 24/7.
Quick answer: what does a new furnace cost in Fresno?
Average installed prices in Fresno from our pricing guide are about $4,200 for a 60,000 BTU furnace, $5,000 for 80,000 BTU and $6,000 for 100,000 BTU. Higher efficiency models cost more, and extras like new venting, gas line work or ductwork repair add to the total.

Examples of our work
Is it time to replace your furnace?
Replacement is worth pricing when several of these are true:
- The furnace is 15 or more years old.
- It needs repeated repairs.
- A heat exchanger crack was found. A furnace with a cracked heat exchanger should not be used.
- Heating bills are rising, or some rooms stay cold.
- Your air conditioner is also old, and you would rather replace both at once.
Gas safety and your installer
A gas furnace has to be vented correctly and connected to the gas line safely. Ask any contractor who bids on a furnace job to explain the venting plan, whether the gas line needs changes, and whether the permit is included.
Keep a working carbon monoxide detector on every floor and near bedrooms. If your detector sounds, or you smell gas, leave the house and call 911 or PG&E from outside.
How a furnace replacement works
- We look at your home. The existing furnace, venting, gas line, ducts, thermostat and where the furnace sits.
- We size the furnace. Capacity from your home's heating needs, not the old furnace's size. An oversized furnace short cycles and heats unevenly.
- You get the options and prices. Efficiency levels, whether a heat pump suits your home, and what each costs, before any work begins.
- We handle the permit. Replacements need a permit, and California's energy standards can add duct testing and sealing steps.
- We install and remove the old furnace. Venting, gas connections, electrical and thermostat included.
- We test it and walk you through it. We confirm it heats safely, check the venting and combustion, and show you the filter and thermostat.
Choosing an efficiency level
Furnace efficiency is rated in AFUE, the share of fuel that becomes heat. Higher ratings cost more up front and use less gas. Typical price steps from our guide:
| AFUE rating | Tier | Added to base price |
|---|---|---|
| 80 percent | Standard efficiency | Base price |
| 90 to 92 percent | Mid efficiency condensing | Add $400 to $900 |
| 95 to 96 percent | High efficiency | Add $900 to $1,800 |
| 97 to 98 percent or more | Premium modulating | Add $2,200 to $4,000 |
Fresno's heating season is short and mild, so the highest efficiency furnaces take longer to pay for themselves than they would in a colder place. Ask us to compare the operating cost for your home.
Furnace or heat pump in Fresno?
Fresno cools much more than it heats, and its winters are mild. That makes a heat pump a strong option, because one system covers both seasons, and it can replace both your furnace and your air conditioner when both are old.
A new gas furnace is still a sound choice, especially if your gas heat is working well and your AC is fairly new.
A heat pump needs enough electrical capacity and ducts in decent condition, so we check those before recommending it. See heat pump installation in Fresno.
On the rules: a California statewide standard for zero emission furnaces has been proposed but, as of mid 2026, had not been adopted, and the Bay Area's rule does not cover Fresno. You are free to install a gas furnace today.
Questions Fresno homeowners ask before replacing a furnace
What about my air conditioner?
The furnace and AC share the blower and the ducts, and the indoor coil often sits on top of the furnace. If you replace the furnace, we check whether the coil and outdoor unit still match.
If the AC is also near the end of its life, that is the time to price both.
Are my ducts good enough?
After 20 years, ducts may leak or have been sized for the old equipment. A new furnace connected to bad ducts will not heat evenly. We check during the estimate.
How loud will it be?
Variable speed and two stage furnaces run more quietly than single stage ones, and they hold temperature more evenly. They also cost more. We explain the options with prices.
Rebates and incentives
Heat pump rebates do not apply to a gas furnace, and the main California one (HEEHRA) is closed to new single family reservations anyway. The rebates and rules guide has the full picture.

Common questions
How much does a new furnace cost in Fresno?
Average installed prices in our guide are about $4,200 for 60,000 BTU, $5,000 for 80,000 BTU and $6,000 for 100,000 BTU. Efficiency, venting and ductwork change the total.
Do I have to switch to a heat pump?
No. A statewide standard has been proposed, but as of mid 2026 it was not adopted, and the Bay Area's rule does not apply in Fresno.
How long does furnace replacement take?
Often about a day, depending on the venting and the permit. We give you an expected schedule with the quote.
Do I need a permit?
In most cases yes. We handle it.
What size furnace do I need?
It depends on your home's heating needs, not only its square footage. We size it for your home.
How long will a new furnace last?
Often 15 to 20 years for a standard furnace with proper sizing and yearly maintenance. See the furnace installation pricing guide.
Is a heat pump better than a furnace in Fresno?
For many homes yes, because winters are mild and a heat pump also cools. It depends on your panel, ducts and energy costs. We compare both with prices.
