A/C or HVAC systems have become increasingly more complicated over the years. They are made up of a series of high voltage (220 VAC) low voltage (24VAC) and high pressure liquid and gas refrigerant circuits. While we recommend that you do some basic diagnostics please leave the more aggressive troubleshooting to trained technicians. We have listed some items below you can check to verify operation. We offer repair and service on all brands of air conditioning and heating systems.
