If your furnace and AC are both aging out at the same time — which is common, since they're often installed together — replacing them as a matched system is usually the smartest long-term move. Below is honest, local 2026 pricing so you can budget before you ever pick up the phone.
2026 HVAC replacement price ranges in Fresno
| What you're replacing | Typical installed price |
|---|---|
| Gas furnace only | $4,500 – $9,000 |
| Central AC only | $6,000 – $14,000 |
| Full furnace + AC system (standard efficiency) | $9,000 – $13,000 |
| Full furnace + AC system (high-efficiency) | $13,000 – $18,000 |
| Premium / variable-speed full system | $18,000 – $20,000+ |
| Heat pump system (heating + cooling in one) | $10,000 – $18,000 (before rebates) |
These are realistic Central Valley ranges for a complete, professionally installed system including equipment, labor, removal of the old units, and standard permits. The only way to know your exact number is a free in-home estimate — we measure your home, inspect your ductwork, and hand you a written, all-in price with no surprises on installation day.
What drives the price of a new furnace and AC
No two Fresno homes are identical, so an honest quote always starts with an in-home assessment. The biggest factors that move your price up or down are:
- System size (tonnage & BTUs): A 2-ton system for a small home costs far less than a 5-ton system for a large two-story. Correct sizing comes from a load calculation — not a guess off the old unit's label.
- Efficiency ratings (SEER2 & AFUE): Higher-efficiency equipment costs more up front but cuts your year-round PG&E bills. In Fresno's long cooling season, the payback on a higher-SEER2 AC can be significant.
- Ductwork condition: Old, leaky, or undersized ducts may need sealing, repair, or resizing to deliver the performance you're paying for. Ductwork work is one of the most common add-ons.
- The R-454B refrigerant transition: New AC systems use next-generation refrigerant, which has affected equipment pricing industry-wide. Here's what that change means for Fresno homeowners.
- Brand and features: Single-stage systems are the most affordable; two-stage and variable-speed systems cost more but run quieter and hold a more even temperature.
- Removal & site work: Hauling away the old equipment, new pads, line sets, thermostats, and code-required safety upgrades are all part of a complete job.
Why replacing both at once usually saves money
When one system fails and the other is close behind, replacing both together almost always costs less than two separate jobs:
- One crew, one trip: You pay for labor and setup once instead of twice.
- A properly matched system: A furnace and AC engineered to work together run more efficiently and protect each other's warranty — mismatched components can actually void coverage.
- Bigger incentives: Full-system installs often unlock larger manufacturer rebates and financing offers than a single piece of equipment.
Tip: Be cautious of any company that gives you a firm price over the phone. Without seeing your home, ductwork, and electrical, that number is a guess — and guesses tend to grow on installation day. A real quote is in writing, after an in-home visit.
Rebates and financing can lower the cost
A new high-efficiency system — especially a heat pump — may qualify for federal tax credits and California rebates worth thousands of dollars. We also offer flexible HVAC financing with low monthly payments and $0 down for qualified buyers, so you can install now and pay over time. See our 2026 California HVAC rebates & tax credits guide for what you may qualify for.
Should you repair or replace?
If your equipment is under about 10 years old and the repair is minor, fixing it is usually the smart move. If your furnace or AC is 12+ years old, uses phased-out R-22 refrigerant, or needs an expensive repair like a heat exchanger or compressor, replacement often makes more financial sense — and bundling both is where the savings are.
