"Holtzople installed a new HVAC for us in Nov 2025. The furnace worked like a champ all winter. As the weather warmed up today, we turned on the AC. Not working. Called Holtzople for service and the intake was a smooth process. Got a call from Tim, who was in the area on another call. He came by a little later and did the systematic troubleshooting. Isolated the issue to a defective sensor. After 2 hours of persistent effort, we are up and running. Great company. Highly recommend them. Been a customer since 2002 and only good experences."

"My system stopped working and I have a newborn so I was panicked and called Dean’s. I live an hour away but Mike came to my house and had me up and running in no time. Highly recommend Dean’s to anyone!!"

"They contacted me right away, set up an appointment, came and did a wonderful presentation that was on a Tuesday. I had other contractors in between. They already sent me their estimates. I waited till that Saturday. And I emailed him, that I wanted to get his estimate. Never received anything. The following Monday, I called his number. He never got back with me. I told him what I wanted. He never got back to me. On Tuesday, which would have been a week after he was here. I called H L Bowman, and spoke with somebody there. She said she would check into it, and she would have an estimate to me within a day or two. And they never got back with me. I never got an estimate. And we checked our email address. Make sure everything was good. Never received anything. And here it is like, over two weeks later and havent heard a word from them. "

"I have had my system for over 2 years and my main biggest hearing unit has never worked correctly. Prime installed this unit and has tried to bandaid this for 2 years. A couple months ago I was told where prime installed the unit at was causing the problem and I could pay extra money to have it moved due to there installation error. I want happy about that and voiced that through a message. 2 months later and prime has yet to fix our even reach out about this issue. This is poor customer service and for a problem that has existed since install. I also pay for the monthly service and extended warranty, still no fix. "

"Good guys. Fast service. Worked with me to schedule the job at my convenience. If you are in need of a new heat pump, definitely get a quote from Comfort Zone."

"Will Stahl from Stahl Mechanical called me the same day that I submitted my request for a pro. He came to my home for an estimate a few days later. He was knowledgeable about AC and electric, educating my husband and I regarding the different systems available, cost and efficiency. He and his 2 guys arrived the following week on time and finished the job in less time than estimated. Will was skillful, clean, respectful and friendly. He was genuinely concerned with the quality of his work and assisted us in setting the smart thermostat and returned upon request at no extra charge to adjust the vents to balance the air flow in all the upstairs bedrooms. I would highly recommend him to others and have given his card out to friends and family already."

"Good professional work!"

"Derrick From 717 Home Comfort arrived within the time he said he would. He got right to work on my furnace and within 20 to 30 mins fixed and had my system running, I had tried two different Companies in the past who charged me but could not solve the issue. 717 Home Comfort has earned both my trust as well as my Business.
