What we did
This Danville homeowner called us in June because the air conditioning unit at the house was not working. With a Kentucky summer already underway, a dead AC is more than an inconvenience, so we went straight to finding out what the system was actually doing rather than guessing at parts.
Our readings showed the system was low on charge. Rather than just topping it off, we ran a pressure test first. Refrigerant is not supposed to get used up in normal operation, so a pressure test is a sensible step before charging a system back up. Once the test was complete, we added the refrigerant the system required and confirmed the air conditioner was operating as intended before we left.
A system running low on charge has to work harder to move heat out of the house, and it can struggle to keep up on the hottest, most humid days. Getting the charge right, and testing the system before doing it, gives the equipment a fair chance to cool the way it was designed to. If your AC quits or seems to be falling behind, a proper diagnosis is the place to start.
