Ac blowing hot and pressure read 135psi , how do I fix .
My ac blows hot , I checked pressure and it's in red (135).
How do I fix this problem
Sounds like you have air in the system. This is caused by a leak in the low (suction) side of the refrigeration system. The system will have to be pulled down into a vacuum and checked for leaks. Once the leak is found and repaired it can be recharged. Normal low side pressure is about 35 PSI with R134a refrigerant. Hope that helps! Jim
