Heating & cooling
AC & HVAC repair in Oakland.
Furnace, heat pump, and ductless work from Montclair and Rockridge down to the Grand Lake flats.
Oakland is a heating town. The flats around Temescal, Grand Lake, and Adams Point rarely see a punishing summer afternoon, and the hills sit above the fog just enough to warm up without ever needing Tri-Valley-grade cooling. So the system that matters here is the furnace, and Oakland furnaces are old, because Oakland houses are old.
Rockridge and Crocker Highlands are largely 1910s and 1920s construction, Montclair runs 1920s through the 60s on steep lots, and what lives in those basements ranges from decent 90s equipment to gravity-furnace conversions that have outlasted every appliance in the house. A good number of homes, especially in the hills, have no ductwork at all, which rules out the standard answers and makes ductless the working tool of this city.
We cover our regular ZIPs, 94602, 94609, 94610, 94611, 94612, 94618, and 94619, out of San Ramon, seven days a week. The diagnostic is $75 and comes off the bill when you book the repair, with a written, itemized quote first. EPA Section 608 Universal certified, CSLB #1136642.
Old houses, old heat
A pre-war Oakland basement can hold anything: a modern condensing furnace, a 1980s unit on its third blower motor, or a converted gravity furnace with octopus ducting from another era. We repair what is safely repairable, and on the oldest equipment we are direct about the line. A cracked heat exchanger or ducting we should not be disturbing ends the repair conversation, and we put that in writing rather than patching around it. See furnace repair for the day-to-day faults: igniters, flame sensors, inducers, and limit switches.
Hillside houses in Montclair add access work: equipment in tight crawlspaces, condensate runs across finished spaces, and outdoor units that need a real mounting plan on a slope. We scope that before quoting, not after.
No ducts is not a dead end
For the houses that never had ductwork, ductless heat pumps are the answer that respects the building. Wall heads in the main rooms, an outdoor unit placed where the slope and the neighbors allow, and no chases cut through 100-year-old plaster. We install Mitsubishi and Daikin, with Daikin factory training and completed Mitsubishi Electric factory courses, which matters when a head throws a communication fault years later and the fix is in the branch box.
Fire season changed the math on cooling here. A heat pump is not only for the few genuinely hot days; it lets you keep the windows shut and the air filtered during smoke weeks, which is when Oakland actually suffers. Owners who never wanted AC ask for exactly this now.
Heat pumps and the rebate picture
Oakland is in Ava Community Energy territory, and heat pump projects can stack programs from Ava, BayREN, and PG&E plus manufacturer instant rebates. The amounts shift by funding cycle, so we confirm what is actually paying when we write the estimate. On older homes the honest first check is the electrical panel, because a 60 or 100 amp service constrains what we can add, and we would rather tell you that at the estimate than on install day.
For replacements and conversions, see HVAC installation. Installs carry a 10 year parts and labor warranty, in writing.
Common questions, Oakland.
- My Oakland house has no ducts. What are my heating and cooling options?
Ductless heat pumps are the standard answer for pre-war Oakland homes. Wall-mounted heads heat and cool the main rooms without cutting chases through old plaster, and the outdoor unit goes where the lot allows. We install Mitsubishi and Daikin and service both at the component level.
- Can you repair a very old furnace, or will you just push a replacement?
We repair what is safely repairable, and plenty of older Oakland furnaces still qualify. The hard line is safety: a cracked heat exchanger or ducting that should not be disturbed ends the repair path, and we tell you that in writing with options priced side by side. No scare tactics, just the finding.
- Is a heat pump worth it in Oakland's mild climate?
Yes, and the mild climate is exactly why. A heat pump runs efficiently in our winters, covers the few hot days, and lets you keep windows closed with filtered air during smoke season. Oakland is in Ava territory, so rebate programs through Ava, BayREN, and PG&E can apply. We confirm current amounts at the estimate.
