The brand on the cabinet matters far less than most people think. What decides whether a new AC delivers its rated efficiency for fifteen years is the installation, and a sloppy one gives away a big share of that efficiency on day one. Size it too large and it short-cycles, pulls out little moisture, and leaves your San Francisco home cool but clammy. Size it too small and it runs nonstop without ever catching up on the hottest afternoons. San Francisco HVAC avoids both by running a proper load calculation based on your square footage, insulation, window exposure, and ductwork, rather than simply copying the old unit's tonnage.
Most of our service calls are for AC Repair. Start there if your system isn't running right.
Warning Signs for AC Installation
Spotting the early warning signs lets you act before the problem gets expensive. Watch for these telltale signs:
- Repair calls that keep coming, with bigger bills every time
- An air conditioner that is twelve to fifteen years old or older
- The house cools unevenly, with hot rooms the system never conquers
- A system that runs nonstop on hot afternoons without hitting the setpoint
- The system still uses phased-out R-22 refrigerant
- Higher cooling costs each year with less comfort to show for it
- An older unit facing a compressor failure or a leaking coil
- The house feels cold but sticky, a classic sign of oversizing
