"Our AC went out and they sent someone out within a few hours and the problem was fixed quickly. With our service membership we also got a discount so the repair price was reasonable. I was very impressed with how quickly and professionally they fixed the problem especially in the middle of summer when they must get a lot of AC calls. Will definitely continue to use Hartman Bros."

"Every thing went well, even though he had bad news that the unit needed to be replaced due to the fact that the unit was 18 years old and the refrigerant used in the day was R22 that it cant be purchased because of government regulations, now we will see what the estimate will be. The technician seems to be knowledgeable and was very professional about his work."
