hvac service calls can be as simple as a tripped switch or blown fuse, or as complicated as diagnosing a damaged txv expansion valve in the air handler. you never know what you're going to get while on service. don't rush, give every air conditioning unit your full attention and get them running properly. happy troubleshooting!
