So, I had a tech come out today. The breaker appeared to be functioning correctly when I was there. He says there is power to the unit but he says that the compressor is "locked up tighter than a drum" due to it being completely void of coolant. He said that there is a leak in the system that caused his 100 PSI of test nitrogen to leak out at a rate of 1 lb./minute. Says that, at a minimum, compressor needs to be replaced and leak needs to be fixed.
He advised that the previous tech who serviced the system a few years ago erroneously injected liquid dye into the system to attempt to find a leak, and that the dye kills the compressor eventually. To use his words, he said that "whoever did that didn't know what they were doing and shouldn't have done that." I told him that it was someone from his company. He completely ignored that statement.
He quoted me a price of $1,200-1,500 for just the compressor replacement and to refill the system but recommended against this option due to the age of the system. Said replacing the compressor was pretty much going to be a short-term fix until the same problems recurred due to the leak. This price did not include leak repair.
Instead, he recommended an entirely new HVAC for $4,200-5,000 due to the age of the system to ensure no future problems. New copper tubing, new units, new everything.
I don't have a good feeling about this, given that this guy is at least partially blaming his own company when it comes to the dye issue. I'm feeling like I'm getting taken on this deal with either option.
It cost me $75 to have him come take a look. Should I get a second opinion or is this legit? This is a rural home and it can be a little difficult to make arrangements to have it looked at since I live 100+ miles away from the place (this is lake property). I'm willing to spend another $75 to get another opinion.
Also, I'm a pretty competent DIY'er. Is replacing the copper lines/attempting to fix the leak myself and/or replacing the compressor myself and then having someone come test and charge the system even an option here? Or is this something I shouldn't even touch?
