Why Petaluma Homes Are Different
Petaluma’s HVAC work is shaped by the same thing that shapes the town itself: a mix of hundred-year-old Victorian stock near downtown, 1960s and 1970s ranch homes on the east side, and newer builds along the western hills. Older Petaluma homes often have ductwork that was sized for a time before central air was standard, so when we run an AC repair or heat pump install, we’re frequently correcting airflow problems a previous owner never addressed. The Petaluma climate compounds it. Summer mornings sit under the coastal marine layer, but by mid-afternoon the inland valley can run fifteen degrees hotter than the bay, and systems that work fine at the coast get pushed hard in the east Petaluma microclimate. We plan for that swing on every job.
Permits matter here. Petaluma’s building department enforces Title 24 energy standards on equipment replacement, and certain historic districts add review layers for anything visible from the street. We pull the paperwork and handle that side, but it means a Petaluma heat pump installation is rarely a drop-in swap. The home’s age, the district, and the existing duct design all drive the scope. It also means the written price we hand you accounts for all of it before we start, not after.
Our Main Petaluma Services
These are the three jobs Petaluma homeowners call us for most. Each has its own page with full pricing, timelines, and what the visit looks like.
AC Repair in Petaluma
When a Petaluma AC quits on a summer afternoon, the humidity hasn’t burned off and the house won’t cool down at night. Most repairs in Petaluma are straightforward: failed capacitors, contactors, refrigerant leaks, clogged condensate lines. We diagnose the fault, put the price in writing, and fix it the same visit when parts are on the truck. In east Petaluma, we regularly see systems that ran hard through the afternoon heat spike and the capacitor gave out first, which is an inexpensive repair when caught early. Full details on AC Repair in Petaluma.
Heat Pump Installation in Petaluma
Heat pumps are the right fit for Petaluma’s mild winters and often-summer-fog pattern, and more homes here are replacing gas furnaces with them every year. A proper install means sizing the unit to the home’s load, not just matching the old unit’s tonnage, and many Petaluma homes need a ductwork correction or an electrical panel upgrade before the new system goes in. We give a written fixed price for the entire job, including any permits Petaluma requires, and a set install date. See the full breakdown on Heat Pump Installation in Petaluma.
Furnace Repair in Petaluma
Petaluma’s winter nights drop into the 30s, and older furnaces in the city’s ranch homes and Victorians take that cold-weather load year after year. Common failures here: cracked heat exchangers (a safety shutdown, every time), failed ignitors, bad gas valves, and limit switches tripping. We service all nine major residential brands, and our vans carry the common parts so many Petaluma furnace repairs are completed in one visit. The repair is guaranteed in writing for a full year.

Pricing for HVAC Company in Petaluma, CA
These are the line-item ranges we see across Petaluma, based on the work itself. You’ll get a written price before any work starts, on every job, without exception.
| Service | Typical range in Petaluma |
|---|---|
| AC repair (minor electrical, capacitor, contactor) | $150 – $650 |
| Furnace repair (ignitor, gas valve, limit switch) | $150 – $700 |
| AC installation (full system, depends on size and ductwork) | $3,500 – $7,500 |
| Seasonal tune-up | $80 – $200 |
Older Petaluma homes with original ductwork tend to push AC installation toward the higher end of the range, because the job includes correcting airflow before the new equipment goes in. What doesn’t change is the guarantee: every repair carries a full-year written guarantee, and if the work doesn’t hold, we return at no charge.
