"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!"

"We purchased our home just a few days ago and the heat was not working, and we were in single digit temps in this area. Josh, our tech, came out and checked everything out and discovered it was a programming issue on the digital thermostat. He set it correctly and heat is now working. The level of service of Hartman is phenomenal! Vickie in the office deserves a big thank you as the house was at 45 when I called and she saw to it that we were worked into their busy service request schedule."
