Why This Exists

Most people don't need a truck roll — they need to know what's wrong

A huge share of HVAC service calls turn out to be a dirty filter, a tripped breaker, a full condensate pan, or a thermostat setting. Everything AC DIY exists to get you to that answer immediately, in your own words, without waiting on hold or guessing from a forum thread written for a different system.

When it really is something that needs a licensed technician — a failed capacitor, a refrigerant leak, a cracked heat exchanger — the tool says so plainly, and tells you exactly what to describe to whoever you call, so the visit is faster and cheaper.

How It Works

Built on a real diagnostic tree

The assistant is built around the same symptom-to-cause logic a technician uses on a first visit: rule out the simple, common causes first, narrow using a few targeted questions, and only recommend a professional when the likely cause requires one — refrigerant, gas, or live electrical work.

It draws on the same repair library published on this site, so the reasoning behind every answer is something you can also read for yourself.
