"My husband and I were very pleased with the quality of service we received today from Caleb. He worked very hard to figure out why our furnace wasn't working. He also cleaned the coils which provided us with better air quality. We are now enjoying a cozy warm home again. Thank you Caleb for a job well done."

"The service was great as always. The 2 men who came to install my new furnace were very professional and took the time to explain what they were doing and showed me what the problem was with my old furnace. Thanks Mr Hartman for coming up North and for having a great crew."

"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."

"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."

"As always, Hartman Bros does service RIGHT! They are prompt, courteous, professional, clean and fairly priced for all services we've ever had completed. We were introduced to them in 1998 when we first used their services and have been faithfully returning for every Heating and Air need, including the building of 2 new homes. They are stellar performers providing excellence at a time when mediocrity has been touted as the norm in our society. They go well above and beyond in all they do."
