Stay away. Technician...I use that term loosely, shows up and after being outside for 5 minutes asks to borrow some of my tools! Comes back inside and explains that my unit is ok, however it is old and out of date and I need a new one. RIPS out a laminated folder with new units starting at, wait for it, wait for it, 21,000.00. Yes, 21 grand to replace my "old piece of crap which is working fine" THEN, I was asked how I heard about them, I explained and he shook his head in amazement using explatives to describe why he couldn't understand why his family would hire such x$$##xxx###. Save yourself a LOT of frustration and hire a real HVAC contractor. Funny part about is I told him I was in the business from the get go and he still tried to smoke me. Unreal. Go elsewhere at all costs.
