What affects the price

HVAC repair costs change based on a few main things. The age and brand of your unit play a big role, as older systems sometimes need parts that are harder to source. The nature of the problem is the biggest factor—a simple capacitor swap is much cheaper than addressing a refrigerant leak or a failed compressor motor. Labor time also depends on how easily a technician can access your equipment in a tight attic or crawlspace. We provide exact pricing confirmed free on the call.

Frequently asked in San Francisco

Why is my AC running but not cooling?

Several things could cause this in San Francisco's climate. Low refrigerant, a dirty air filter, or a malfunctioning compressor are common culprits. The outdoor unit might also have debris blocking airflow. A licensed pro can quickly pinpoint the exact reason your system isn't delivering cool air.

What does a typical AC repair cost?

What is the 3 minute rule for AC?

The 3-minute rule for AC systems advises against cycling the unit on and off rapidly. This is because the compressor needs time to stabilize its pressure after shutting down. Constantly restarting the AC can put undue stress on the compressor, leading to premature wear and tear in any climate.

How much does an average HVAC job cost?

The 'AC rule of thumb' suggests that if a major AC repair costs more than half the price of a new system, it's often more cost-effective to replace it. This guideline helps you weigh repair costs against the long-term investment in a new, more efficient unit for your San Francisco home. It’s a good way to think about significant repair expenses.
