Why is my BMW air conditioning not cold enough?
One of the most common reasons your BMW’s air conditioner isn’t working is because of an A/C leak. The fluid that is used to cool your car, freon, could be leaking out of your car, or there might be a bigger leak in the A/C system. A professional mechanic can identify A/C leaks with the proper equipment.
Do you add to the high side of the low side on air conditioning system?
Every auto air conditioning system has two service ports: one on the high pressure and one on the low pressure side. When recharging with AC Avalanche refrigerant, for safety, you will charge through the low side service port. Never charge through the high side port.
What type of freon does BMW use?
R134a
A/C BMW refrigerant filling quantities R134a an 1234yf.
What should my AC low side pressure be?
When the engine is on and the AC is on high, low pressure readings should be around 30 psi and the high pressure side should be about 250 psi depending on your car. The correct reading will display once the clutch engages and the gauge stops cycling.
Why is my air conditioner not cooling my house below 80?
So if there are leaks along the ductwork that allow cold air to escape into the attic or basement, your home won’t get as much cool air as it needs to reach your set temperature. Air ducts with leaks allow conditioned air to escape into unconditioned areas (i.e. the attic).
Is the air conditioner low or high on the high side?
The compressor will turn on and cycle at 45+ psi, but doesn’t stay on. It’s rated and charged at 60psi (low side), which is normal. The high side pressure is low, at around 120 psi when it should be much higher in the 400 275-300 range. The pressures do equalize when the engine is off.
How can I check the low side of my AC?
If you want to easily check the pressure readings of your AC system, a simple way to do it is by using a pressure gauge, which you can buy for a cheap price at your local shop or from online stores like Amazon. Just follow the user instructions of the pressure gauge to read your AC’s high side and low side pressure.
