Hottest day of the year and my air conditioner goes out! Isaac pinpointed the electrical problem within minutes and fixed it immediately. I mentioned a possible problem with my ductwork, he went under the house, and sure enough, found a hole where all of my air was leaking! He patched the hole and we discussed a more permanent solution in the future. This is the coolest my house has been in 2 years!! Thanks Isaac!!!

Came out to call. Customer stated that the upstairs system was freezing up and wasnâ€™t cooling properly last week. They changed the filters Thursday to see if that would change it, and it started freezing up again on Friday. I cycled upstairs unit and checked operations.
