Where do most HVAC installations go wrong? Most often before the first wrench turns, when someone matches the new tonnage to the old nameplate and skips the math. At San Francisco HVAC, the math comes first. We build a load calculation for your San Francisco, CA home from its square footage, insulation levels, windows, orientation, and air leakage, because a system sized by habit rather than by measurement is wrong from day one. From there the job becomes three connected pieces of work: equipment matched to the load, ductwork able to deliver what that equipment produces, and a commissioning process that proves the result on the meter instead of on paper.
Our two most requested repairs are AC Repair and Furnace Repair. If something has stopped working, start there.
Signs You Need HVAC Installation in San Francisco
Spotting the early warning signs lets you act before the problem gets expensive. Keep an eye out for the following clues:
- Major components failing on both sides: compressor one year, exchanger the next
- Rattling, humming, or roaring loud enough to interrupt conversation
- Utility bills rising each season as comfort slips
- Rooms that never reach temperature no matter how the vents are adjusted
- An older system charged with phased-out R-22
- Your furnace and AC have both passed twelve to fifteen years of service
- New square footage that the old equipment simply cannot keep up with
- Air that feels cool but damp in summer, a classic oversizing symptom
Act Before It Gets Worse
A failing capacitor, clogged condensate drain, or dirty flame sensor rarely fixes itself and usually gets more expensive to address the longer it runs. Call (415) 234-5360 at the first sign of trouble.
