What goes on during a full heating/AC repair — inspection, diagnostics, and typical fixes
Hey everyone, I’m trying to figure out what actually happens when you get a full heating and AC repair. Last week my furnace stopped blowing hot air, and I had no idea what the tech was doing. They seemed to be poking around a lot, checking wires and filters, and I was curious if that’s normal. Do they usually go through the whole system from top to bottom, or just fix the part that’s broken? I want to understand what I should expect before calling someone next time.

Yeah, that’s pretty normal. When I had my AC go out last summer, the tech came in and basically did a full inspection first—checking everything from the thermostat to the wiring and even the drain lines. They ran diagnostics to see what part was faulty, then suggested the typical fixes. Honestly, watching it was kind of eye-opening. If you’re looking for a good idea of what a full service looks like, I found this page on Car AC not blowing cold air https://www.vip-servicecenter.com/services/heating-and-air-conditioner-repair really helpful. It breaks down what they check and the common fixes they perform. I felt more prepared after reading it.
