Hello, I have a Heil 3 ton central ac unit. It was installed when my house was built (2006). The compressor took a crap. I had a guy come look at my system and said the compressor needs replaced. Anyway, before determining it was the compressor,he installed a hard start kit. He can install a new compressor,and fill Freon. He says its about $30 a pound. Everything for $1200.00 total. Does this sound right? Am I getting a good deal? Thanks for your opinion.
