"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!!"

"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!"
