Why is my AC cutting on and off?
Your air conditioner may be short cycling because it is repeatedly starting up then overheating (and shutting down) due to a bad compressor, dirty filters, dirty coils, low refrigerant, or frozen coils. An overcharged system will cause liquid Freon to get into your compressor and cause it to malfunction.
What causes AC compressor to turn on and off?
When your refrigerant is low, the needed compressor-pressure levels are affected. This triggers your compressor’s low pressure control, shutting off your compressor. When the pressure rises and triggers your AC to restart, this causes the short cycling. Low refrigerant can also cause frozen coils.
Why does my AC compressor keep shutting off?
The compressor on your A/C unit is the engine of the refrigerant cycle. It generates the pressurized conditions through which the refrigerant absorbs and dissipates thermal energy, cooling your home. If the compressor is overheating or is worn out, this will often result in the system shutting off frequently.
Why does my car AC randomly shut off?
If the compressor turns on then instantly stops it could be either you are lacking freon or there is too much in the line. If you over charge most compressors will turn off if it notices the pressure is above a certain limit. When it gets hot outside it also causes the pressure to rise which can cause this issue.
Why does my car air conditioner work sometimes and not others?
Intermittent cooling is often caused by the components of your vehicle’s AC system freezing up. Typically an iced over evaporator is the culprit. There may be numerous issues causing the icing—from a dirty cabin air filter to a blocked evaporator drain or an overcharged system.
Why does my AC turn on and off every few seconds?
Got a central air conditioner that turns on and off every few seconds or minutes? This is called “short cycling” (because normally the AC has a regular on and off “cycle” that varies with the outside temperature.) Short cycling wears out the outside unit’s compressor.
Why does my Subaru Legacy Run low on AC?
The 2000 to 2004 Legacy and Outback suffer from leaks at the 2 Ac hoses one from the compressor to the condenser and one form the compressor to the Evap core. This causes the system to run low or empty.

What’s the problem with intermittent air conditioning in Subaru?
Hey everyone! Enter your ride HERE to be a part of this month’s Outback of the Month Challenge! Just thought I’d share my problem/solution in case it helps anyone else with intermittent air conditioning. I was having a problem with my a/c system either working or blowing hot air.
What to do about intermittent a / C in Subaru Outback?
To solve the problem, I used a screwdriver to push the clutch in and out (the travel is about a 1 mm to 1.5 mm). I repeated this to all sides of the clutch to ensure that it moved as freely as possible. I then used compressed air to blow out dust from the inside of the clutch and sprayed a little oil in there to keep things lubed up.
