Suddenly my A/C has low cooling output at below 1000 RPM
Pressures are 250 to 275 on High and 50 on low at idle going to 35 at 2500 RPM Outlet Temps hover at 60 degrees after a while.
No bubbles in sight glass. Need advice. Have had one suggestion that a clogged or blocked expansion valve could be the problem. Would like to hear what a replaced expansion valve should run. Would like to hear of ways to "clean out" a 10 year old system that work and are not harmful.
