#1 They actually calculate the size of unit you need, not just guess (I needed a 2 ton). I had 4 quotes done in total, and these guys were the only ones that took the time to measure all the windows. One competitor even said I needed a 3 ton unit. I knew he was full of sh** then and there. Calculating the old school way of 600 sq./ft. per ton.
#2 One other competitor was about the same price, the other 2 were around $900-$1100 more.
#3 They didnt leave a mess or have poor workmanship. They did it right, and didnt screw me around.
Give them a shout. Hard to find decent help these days. These guys fit the bill.
