Q: I think my AC is broken.

asked by on

I don't know if the compressor is what needs replacing. I was driving the other day with the AC on. I noticed the car was struggling to accelerate and the AC seemed like it was chugging. When I got home, it smelled like something was burning. I took it to get the AC diagnosed and was told that the AC system was on low charge at the time. But I was also told that recharging it wouldn't guarantee that it would be fixed. I was also told the vent temp was 60 degrees, low side pressure was 35psi, and high side pressure was 250psi. Ambient temperature was 85 degrees. I don't know what to do. The belt is fine, and I haven't had this issue before. I am debating whether or not to buy a new compressor, drier pad mount, and expansion valve, and just have it all replaced and recharged. Any suggestions?
