I think I just threw away $96. I have central air with a gas furnace and AC. Neither of them has been looked at by a service tech for several years so I had a local company come out for an off-season furnace service; not because there was anything wrong, just to make sure everything's okay and head off any problems before heating season comes around again. I think they advertised it as a "tune-up" but I lost their flyer so I'm not sure about that.
The guy checked the air filter (I stay on top of that myself) and the condensate pump (which is an AC component, not furnace), took a measurement of some kind with a meter I'm not familiar with and said the reading was good. Then he fired up the furnace, and said, "Okay, everything works." Whole thing took about 15 minutes.
I already knew everything was working; I expected him to do something to try and make sure it keeps working. Is this typical? Should a maintenance check involve more than this? I was planning on getting the AC checked also but now I'm not so sure.
