Service within an hour on a Saturday. No extra charge. Told me what I needed, not what he thought he could sell me.
Steve told me what no other AC guy would, that units don't need annual service and as log as you keep the coils clean and filters cleaned, you are good to go. And you should never lose freon unless you have a real problem.
Wife had my checkbook and they had no problem leaving me an invoice to mail a check later.
This is how you run a service company readers. I have my AC company.
