Distance is worth checking yourself: the nearest HVAC company is not automatically the best one, so this page ranks on rating and review volume first and leaves proximity to 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.
