Excellent service. Honest company. We had Garland Heating and A/C come out on a Friday after work to give us a 2nd opinion on our upstairs unit. The 1st quote we had was from a big name A/C company that had also done the original install. This big name company came out in June and filled the system with refrigerant then claimed we needed a new evaporator coil to the tune of $ 1,100. The technician from Garland Heating and A/C put whatever amount of refrigerant he had left after being on calls all day in our system. He said we needed more and he would run back to his office and be back. As it was Friday night, and we needed to get our son fed, we asked if he could come back out tomorrow. No problem! The technician showed up Saturday morning, correctly diagnosed the problem as a hole in the refrigerant line, soldered the hole and filled up our system. Total cost = $ 400!!! We will be using this company for our future heating and A/C needs.
