Searching for HVAC and air conditioning companies near me in San Francisco?

If this is an emergency, call rather than fill in a form. An AC that dies in a heat wave, or heat that dies in a freeze, is the case for calling instead of waiting for morning. Ask up front whether they are dispatching tonight and what the after-hours call-out fee is: 24/7 availability is not something a star rating can tell you.

After-hours availability is not part of a Google rating, so this directory cannot verify it for you in advance. An AC that dies in a heat wave, or heat that dies in a freeze, is the case for calling instead of waiting for morning.

A company that answers both plainly on the phone is usually the one that actually shows up.
