"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!"

"Love these people! We bought a brand new furnace and ac a year ago. For some crazy reason something happened to the ac Sunday when it was 91 degrees . I had a service guy here Sunday and Monday... Vicky was fabulous through it all and the guys were wonderful. They ended up working after hours and got it all fixed... Thank you from the bottom of my heart and my puppies. We're cool again!!"

"Always a tremendous experience with Hartman Brothers. I have used them for more than 25 years and gotten to know their people more like friends/family than vendors... because that's exactly how they treat their customers! Always a pleasure to deal with and their work is exceptional as a bonus. Would give them 6 Stars if it was an option."
