I've been in the HVAC industry for 20 years here in Tucson. As a service technician, I know what the big companies charge for service and repairs. It is too much! Let me look at your system. I'll save you a lot of money because I don't have the overhead like the big companies. I do this on the side. My diagnostic fee is only $40. I'll quote you the price for the repair.
If you accept my bid, I'll drop the diagnostic fee! I also do annual maintenance to keep your system running its best. I'm a cash-only guy. There are no checks or credit cards. So, quit making the fat-cat companies rich. I'm a one-man show, so save your money and call me.
