It may seem intimidating to perform your own system pressure tests, but it is actually quite straightforward to do so. Below is how to measure your central air conditioning system’s pressures to help know whether or not you should contact a technician for servicing:
- Locate your system’s gauge connection valves – central air conditioning systems contain two refrigerant lines connected to the outside units that house the condensers and compressors. The larger diameter line is the suction line that returns gaseous refrigerants to the condenser. The smaller diameter line is the high-pressure line, which is sometimes called the liquid line. At the point where the lines enter the outside unit, look closely and you will see valves that are most likely capped shut. These valves are for the purpose of monitoring refrigerant pressures, both suction and high-pressure.
