The San Francisco94109 calls we answer most often
If your system is doing any of the following, it is worth a diagnostic before the fault gets more expensive.
Musty or burnt smell the first time the system runs
Furnace lights then shuts down after a few seconds
Thermostat reading several degrees off from reality
Short cycling — on and off every few minutes
No cool air, or air that is barely cooler than the room
Skyrocketing utility bills with no change in usage
Heating and air conditioning service built around San Francisco
We keep licensed, background-checked technicians on the road in San Francisco and the surrounding 94109 service area, so a no-cool or no-heat call usually gets a same-visit fix rather than a return trip.
In the 94109 area we see a lot of attic-mounted air handlers. Attic heat soak in summer and cold-soak in winter both shorten component life and make insulation checks part of a proper diagnosis.
If your system is over ten years old and you have had two repairs in the last two seasons, a replacement comparison is usually worth running even if the current unit still runs.

San Francisco94109 HVAC questions, answered
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.
Do you handle ductless mini-split systems?
Yes. Ductless installations have grown quickly in California, particularly in older homes without existing ductwork. We service indoor heads, clean filters and drain lines, check line-set insulation and diagnose communication faults between heads and the outdoor unit.
What causes water to leak from the indoor unit?
Almost always a blocked condensate drain line, a failed drain pan float switch, or a frozen coil melting faster than the pan can handle. In San Francisco we see algae and dust clogging drain lines constantly during May through October. It is a fast fix but ignoring it ends in ceiling damage.
What brands do you service in San Francisco?
All of them. Our 94109 technicians are trained on Trane, Carrier, Daikin, Mitsubishi Electric and essentially every other residential brand sold in California, including discontinued lines. We keep a broad parts catalogue on the trucks for exactly that reason.
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 often should I change my filter in 94109?
Monthly inspection and replacement every 60 to 90 days is the baseline. Homes in San Francisco with pets, ongoing construction nearby, or a high-MERV filter in an undersized return should move to monthly changes. A loaded filter is the single most common cause of frozen coils and failed blower motors.
