Why does my car AC cycle on and off?
Short cycling, when the compressor constantly shuts on and off, is one of the most common air conditioning problems. Several conditions cause short cycling, including a faulty or obstructed thermostat, leaking refrigerant, icy coils or an HVAC system that is too big for the building in which it is installed.
What’s the pressure on the air compressor in a Honda Civic?
This time, I revved the car up to about 1,500 to 2,000 RPM (since the Civic seems to idle at around 500 rpm). Sure enough, he said that the low pressure was being sucked down to about 20 PSI and the high-pressure was kicking way up again past 400 PSI.
Why is my car air conditioner cycling on and off?
I turned the A/C off and stopped putting R-134a into it becuase the compressor cycling was almost causing the car to die from the load it was putting on the engine. Onto Google I went. Everywhere I turned, people said that if the compressor was cycling on and off quickly, that meant the compressor was low on freon.
How much R-134a can a Honda Civic hold?
He agreed and thought that I may have overfilled it – but said he hasn’t ever noticed a car doing that before. The Honda Civics can hold up to 22 ounces of R-134a in them. A 12-ounce can would be just more than half of it’s capacity.
When to cycle the a / C compressor in Honda Pilot?
This switch cycles the compressor. If you watch the low-side pressure and see it dropping to less than 10 PSI or so and cycling with the compressor, the system detects low load or low charge and cycles the compressor clutch.

Why does my AC clutch cycle on and off?
This switch is designed to make sure that the pressure stays at a consistent level so that the AC can function correctly. As this switch continuously cycles on and off, the AC system operates its electrical contacts which subjects the switch to a high amount of wear.
