"Ked was my "usual" service tech for many years. He was always friendly & kind...and didn't mind letting my big dog say hi. He was always professional and efficient. I liked having the piece of mind in knowing my HVAC needs are met & running well. I have used their maintenance plan for many years now, and haven't been disappointed. Well, Caleb didn't disappoint either. He loved my "big boy" and had a great sense of humor. He was very thorough in servicing my air conditioner. I feel I get my money's worth from my maintenance plan each year. I love when they say, "Everything looks good, no problems. See you in the Fall.""

"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."
