"I called 5 star when my AC was blowing cold air. They were here on a Saturday night at 9PM within an hour. Once Billy got here, he took his time explaining stuff and was very patient, as I was a bit nervous it was going to be very expensive. I am a new home owner, so I really appreciative the time Billy took to explain what was wrong and my different options. He also took the time to show me how to change my filters in the future. I did not feel pushed and did not feel like I was trying to be upsold. Thanks 5 star and Billy High!!"
After the control of air flow and temperature was standardized, the use of electromechanical relays in ladder logic to switch dampers became standardized. Eventually, the relays became electronic switches, as transistors eventually could handle greater current loads. By 1985, pneumatic controls could no longer compete with this new technology although pneumatic control systems (sometimes decades old) are still common in many older buildings.[4]

A contactor is a $25 mechanical relay that uses low-voltage power from the thermostat to switch 220-volt high-amperage current to the compressor and condenser fan. AC contactors can wear out and are at the top of the list of common air conditioning service failures. Even if your contactor is working, it pays to replace it every five years or so. Unscrew the old contactor before removing the wires. Then move the wires to the new unit (photo 6).
