AC Repair FAQ for San Francisco Homeowners

How often should San Francisco homeowners get ac repair?
Given San Francisco's karl the fog: persistent summer fog from the pacific keeps temperatures at 55–65°f on the west side, most homeowners benefit from ac repair at least once a year. Year-round fog moisture causing wood rot and paint peeling on west-facing Victorians often makes spring or fall the optimal time to schedule service.
What home types in San Francisco most need ac repair?
Victorian Painted Ladies and Edwardian flats (most common exterior) and Spanish colonial and stucco in the Sunset and Richmond districts are the most common home types in San Francisco and typically see the most wear. Our local pros are familiar with the exterior materials found across the metro.
Why is my AC running but not cooling?
Common causes include low refrigerant (leak), dirty evaporator coil, failed compressor, clogged air filter, or iced-over coil from restricted airflow. A technician diagnostic identifies the specific issue.
Should I repair or replace my AC?
The 5,000 rule: multiply the repair cost by the unit's age. If the result exceeds $5,000, replacement is often more economical. Also consider: is it over 10–12 years old? Does it use R-22 refrigerant?
How long does AC repair take?
Most repairs are completed in 2–4 hours. Parts availability is the main variable — common parts are often stocked on the truck; unusual components may require ordering.
What's included in an AC tune-up?
A tune-up covers cleaning coils, checking refrigerant levels, testing capacitors and contactors, clearing the condensate drain, lubricating moving parts, and measuring system performance.
