What does low side gauge on air conditioner mean?
Then the low side gauge will climb back up to 45 psi as the high and low side equalize. At this point, he compressor will kick back on and the cycle will repeat itself. This is called short cycling. This rapid cycling of the compressor is a good indication that the system is low of refrigerant.
What’s the temperature on an AC pressure gauge?
Normal high and low AC ambient temperature pressure chart Ambient Temperature in °F Low side Pressure Gauge reading and High side Pressure Gauge reading 65°F Ambient temperature: Low side pressure 25-35 psi High side pressure 135-155 psi
What to do if your AC pressure gauge is not working?
The system is overcharged, there’s a lack of airflow across the condenser (clogged fins, radiator/condenser fans not working or not working at the proper speed), or you have air and moisture in the system. 1. Check the front of the AC condenser (it’s in front of the radiator) to make sure the fins aren’t clogged.
What does the Red side of the a / C gauge mean?
The red, high side gauge is used to measure the high pressure side of the a/c system. This gauge has no markings that indicate vacuum. It reads positive pressure only.

What does a large puddle on the AC gauge mean?
A large puddle is an indication of evaporator ice that has melted and drained onto the ground. OR, continue driving the vehicle with the blower on HIGH while monitoring airflow from the vents. Once the evaporator ices over, you should notice a dramatic reduction in airflow from the vents.
What does it mean when your AC is low on refrigerant?
Refrigerant is the liquid/gas responsible for absorbing heat from your home’s air. If your AC system is low on refrigerant, it won’t cool your home as well as it normally would. Here’s the thing:Refrigerant runs in a closed loopthrough your system. So, if your system is low on refrigerant, it means you have a leak.
