Heating and air conditioning service built around San Francisco
Whether the complaint is weak airflow upstairs, a furnace that will not stay lit, or an outdoor unit that hums but never starts, the process is the same — a proper diagnostic, a written price, then the repair.
Homes in City and County of San Francisco County tend to be a mix of older builds with original ductwork and newer infill construction, which means airflow problems show up very differently from one street to the next.
The busiest week of our year in San Francisco is the first stretch of sustained may weather. Systems that idled all season fail in clusters.

San Francisco94123 HVAC questions, answered
Do you service commercial and light commercial properties?
Yes. Around San Francisco we handle rooftop packaged units, split systems, VRF/VRV installations and building automation faults for offices, retail, restaurants and multi-tenant buildings, including after-hours scheduling so you are not disrupting trade.
Do you charge extra for nights, weekends or holidays?
No. Our pricing in California is the same at 2am on a holiday as it is at 2pm on a Tuesday. Emergency calls are dispatched the same way as scheduled calls and carry no overtime premium.
Is my carbon monoxide risk something I should worry about?
With any combustion appliance, yes. A cracked heat exchanger can spill carbon monoxide into the living space, and it is odourless. We perform combustion analysis and a CO test on every furnace and boiler call in San Francisco, and we recommend a working CO alarm on every level of the home regardless of who services your equipment.
How quickly can a technician get to San Francisco?
For the 94123 service area our target response time is 60-90 minutes from the moment dispatch confirms your address. Real-world timing depends on the day — the first sustained heat or cold snap of the season is always our busiest period — but we hold technicians locally specifically so that window is achievable rather than aspirational.
Should I repair my system or replace it?
The usual rule of thumb: if the repair costs more than half the price of a replacement and the equipment is over ten years old, replacement generally wins. We will run that comparison with you on site and show you the maths — and if the honest answer is a $180 capacitor rather than a $9,000 system, that is the answer you get.
Can you give me a price over the phone?
We can give you realistic ranges — and this page lists the ones homeowners in San Francisco see most often — but a firm price needs eyes on the equipment. Any company that quotes a final number without seeing the unit is usually quoting low to get through the door.
