Furnace replacement & installation in San Diego County
A lot of inland San Diego tract homes are still running their original or second furnace. When yours is done, we swap it in a day — properly sized, properly vented, permitted, and HERS-tested.
Signs it's time to replace
- The furnace is 15–20+ years old and repairs keep coming
- A cracked heat exchanger — that's not a repair, that's a replacement
- Rooms heat unevenly and the blower sounds like a jet
- Winter gas bills keep climbing
- Parts for the model are obsolete or weeks out
What we do
We size the new furnace to the house — not to whatever was there before — match it to your coil and ducts, and install with new venting where code requires. If your evaporator coil or ducts are near end-of-life, we'll tell you now, when combining work is cheap, not next year when it isn't. Permit and HERS test are part of the job, always.
What things actually cost
| Job | San Diego market range |
|---|---|
| Furnace replacement, installed (San Diego market) | $4,500 – $9,000 |
These are the ranges San Diego homeowners actually pay across the market — not a quote. We price your exact job before any work starts, and the number doesn't move after.
Worth five minutes: the heat-pump option
If your AC is also aging, a heat pump replaces both systems with one — it heats and cools, runs on electricity, and we've converted furnace-plus-AC setups to heat pump and air handler in a single day. Ask for both quotes; sometimes the math surprises people.
