Small failures become expensive ones fast. Here's what we rush to, and what to do before we arrive.
Furnace won't ignite, blows cold air, or keeps shutting off — we prioritize homes with kids, seniors, and medical needs.
When it's 100° out, a dead AC is a safety issue, not a comfort issue. Same-day priority dispatch.
A leaking tank can fail suddenly and flood. Shut off the water supply and call — no-hot-water calls get same-day service, 7 days a week.
Leave the house first, call PG&E at 1-800-743-5000, then call us to inspect and repair the system safely.
Blank thermostat, tripping breakers, burning smells — stop running the system and have it diagnosed before damage spreads.
Ice on the lines means shut it down. Running a frozen system destroys the compressor — the most expensive part.
Same urgency, different system — here's exactly what we fix, with same-day priority.

Most emergencies start as small problems. A yearly tune-up catches worn parts before they fail on a cold night or in a heat wave — see our HVAC maintenance service and the $99 tune-up special.
Real, verified reviews from homeowners across San Jose and the Bay Area.
I'm very satisfied with the experience with Promax. Their technicians were always on time for the appointments and on the work day. The heat pump was installed professionally and within the time window they promised. They are professional and very easy to work with. Responses have been very timely and courteous. Strongly recommend.
Heat Pump InstallationI had an airconditioning malfunction. The Promax Pro happened to be in my area when I reached out. He was at my house within an hour, diagnosed and quoted on the spot, and was able to do the repair immediately. Super friendly, professional, fast, and reasonably priced - what a great experience. Thank you!
AC RepairThere was a significant noise when the AC is turned on. They fixed it very nicely within one day by moving air intake away from the motor. They went under the house and did all the connections. They work professionally and clean after reasonably well. Great service…
