AC not cooling repair in South San Francisco: what we fix

The most common reasons an air conditioner stops cooling are low refrigerant from a leak, a failed run capacitor that keeps the compressor or fan from starting, a frozen evaporator coil from restricted airflow, a dirty condenser coil that cannot reject heat, or a tripped float switch in the condensate drain. Each has a different fix, and each is one we handle every day.

South San Francisco customers on our AC not cooling repair

Straightforward pricing, no upsell, and the technician clearly knew heat pumps inside and out. Our system is finally heating properly.

Had them out for an AC tune-up before summer. Thorough inspection, cleaned the coils, and they found a weak capacitor that would have failed in July. Smart move.

AC Not Cooling in South San Francisco: frequently asked questions

Why is my AC running but not cooling?

Most often low refrigerant, a frozen coil, a bad capacitor or a dirty condenser coil. A technician can pinpoint which in about 20 minutes.

Can I just add refrigerant myself?

No. Refrigerant is a regulated substance, and low charge means there is a leak that will drain a new charge just as fast. We find and repair the leak first.

How quickly can you come out?

Same-day service is available across South San Francisco in most cases, and 24/7 emergency dispatch is always on.
