"A technician came out to perform an annual service call on air conditioning/heat pump. He also made a minor adjustment to thermostat programming . He was prompt and efficient and discussed future maintenance regular service options."

"Our technician arrived as scheduled, was courteous at the door and asked if it was OK to come into the house, after which he put his booties over his work shoes. He (I wish I knew his name) seemed to complete his tasks efficiently, cleaned up his workspace and gave a thorough rendition of the condition of our AC unit. I appreciated his work and glad that we had the service contract. Great Job!"

"Josh was very knowledgeable! He was able to find the problem with our furnace and fix it. He was not pushy and didn't try to sell us anything we didn't need! We will definitely do business with Hartman's again when needed!"

"Josh at Hartman Brothers did a good job. He quickly figured out the problem and got it fixed for 1/3 the cost I was expecting! He did not "find" problems or try to get us to upgrade, just did exactly what we needed him to do. I would strongly recommend calling Hartman Brothers for installing or repairing your AC/Heating!"
