This is an issue on my son’s 20 month old heat pump. So what do you all think before I go off and spend big bucks.
2.5 ton Lennox. R-410A
During winter, the compressor would shut down after 2 minutes. First it was a high limit issue, then it was a low limit issue. No leaks. Levels fine. After trying a couple more times, the compressor starts making a strange growling noise after 30 seconds and shuts down.
Installing company tech says compressor is shot. Have to replace. Compressor is covered by warranty but labor (their quote $1500) is not.
Decided to wait until now to have it worked on. So just for S hits and Giggles I reset it one more time since it is 88 degrees out. Unit turns on and runs great. No noises at all. Has kept the house at 71 degrees for 4 days now in 95+ heat and is running smooth.
So before I jump and pay the money to change the compressor, any other ideas out there? Reversing valve? TXV? Anything that might be done without evacuating the system which is where the cost is?
