Gwen from the office then called to let us know what time frame Jeremiah would arrive. I was pleased to see service tech Jeremiah walking around the house even in the snow investigating what the problem could be. After coming inside, Jeremiah tested all of our thermostats, our boiler and checked all of the pipes and vents. He found the problem. He also did a few tweaks and gave us information we much appreciated to keep the boiler running smoothly. He made sure everything was fine, working properly and answered all the questions we had. I definitely will recommend Von Deylen and am glad we had them install our new boiler and air conditioning split system. Jeremiah is professional, informative and more than knowledgeable in his expertise. On an added note, I received a follow up call from Courtney in the office. This rare and extreme polar vertex we have experienced this past week was exceptional and it was nice to know Von Deylen is a company that cares about their customers.” – Penny Zeiter Shamy “We been with them for 4yrs now. 4yrs ago we got a new furnace it's been working great with no issues. We also got mini split heaters for the 2 bedrooms when the basebord heater went out and couldn't be fixed. I would definitely recommend them they are great and so much nicer than the last people we had” – Jody B. “They have great service and repair technicians.

Employees are always very helpful and courteous.” – Denise S. “We have received excellent service from Von Deylen's for over 16 years. When we have had problems they always responded in such a way as to make us want to tell others about our positive results. Chris was our tech who serviced our HVAC system yesterday and did an excellent job while answering several questions that we had. Thank you for providing quality service!” – Philip H. “Had my air conditioning unit go out on one of the hottest days of the summer so far so I gave these guys a call. They were out within an hour, took a look at it and explained to me that it was shot! Then these two guys went above and beyond for us in helping us find a solution so we could have a new unit put in! Would highly recommend these guys to anyone in a tough situation!” – Katelynn B. “I've been using them 10+ years. Their work is always done right the first time and they keep you involved through the whole process of whatever they are doing for you. If problems do pop up on work they have done, I have at least two examples of them doing the repair at no cost to me, one of which was a potentially expensive furnace issue. Highly recommended.” – Kieron D. “Very good job. Thank you.” – E. Dean Beck “Our needs were met. Randy went the extra mile for us.” – Harley H. “After spending an entire day of calling places on Tuesday because our furnace in our mobile home wouldn't work, I called Von Deylen on Wednesday and had an appointment that day for a technician to come out and take a look at the furnace. After about an hour or so, Chris had answers and solutions. We decided to get a new furnace as ours was 16 years old and we couldn't be sure what else if anything was or would go out on it. He placed the order and told us that Friday or Monday it would be installed depending on when I got the call saying it was in. Thursday afternoon I received a call from Von Deylen saying the new furnace was there and that they could be out Friday morning to install it. The technicians were very polite and did their job well! They cleaned up the mess that was made from taking the old furnace out, removed a broken central ac unit for no extra cost and double checked that everything was working properly before leaving. I would personally recommend their services!” – Kassandra S.
