In a really cold snap last winter, Dieter gave priority service to those with no heat at all. That meant a new, energy efficient furnace was installed 10 days sooner than it would have been with other companies I called. Even more important, it meant a total bill that that was well below half of quotes I received from other companies. I could not be more pleased with Dieter's pricing, responsiveness, transparency, quality, and caring attitude. read more

We have used Dieter for all our boiler repairs and replacements for the past 15 years. Having 10 separate systems one in each of our 6 plex condo buildings. The prices are the best we could find. The service is great with them always responding on site within 24-48 hours. Bob has been out when then them is below zero at 4 in the morning to repair the heat when it went down. This is a family owned business and they know what they are doing. When there is a problem they work to get to the source and have you up and running ASAP.. We have never been over charged, even when they came out Christmas Morning and fixed a broken water line that wasn't even to the boiler, it was broken behind a wall and a panicked person called at 4 AM. We trust them to enter the buildings on their own and do what needs done. Our Condo Board trust no one but Dieter's to keep our 60 units heated. read more

Back in 2017 we had an entire new heat pump, inside and outside installed. Bob and his employee Michael installed everything. We came home one day to light switches reversed in the house and one of our cats locked in a room that the door always remained closed to. So we had a bad feeling about what was going on while we had to be away at work. We have one camera in our basement which caught footage of Michael trying to pick the lock to a heavy metal door we have in the basement. Violated is a very appropriate word to describe how we felt after knowing our entire house was rummaged through. But not only violated, scared because we didn't know if he'd come back to our house after the job was done. We found this footage the day after it had happened and called Bob to inform him of this. While Bob did go out of his way to finish the job on the weekend and alone, we made it very clear Michael was not to be on our property again. When doing a small remodel in the house after the fact, we found above the indoor unit, a lock pit set along with a number of our personal items he stashed there, that we can only assume he intended to steal. Which made us go looking above air ducts in the basement. We found multiple piles of copper piping from the brand new line set that was being stashed. Every year since the brand new unit was installed we have had nothing but problems. We continued to call Bob because of the warranty on the unit. Comments like "well you don't want my employee on your property" and "you don't like my employee" we're made- as if we didn't have a solid reasoning behind it. Bandaid after bandaid with Bob. There is no way we should need serviced every spring and winter. I just simply don't believe it. Yet here we are again needing to be serviced this spring. We absolutely will not be calling Bob. The reason we waited so long to make this publicly known was because we didn't want to dirty Bobs name or reputation over what we thought was just an employee problem, who Bob still employs. Along with also being scared of what the repercussions could be by making this public. But after continuous rude remarks and constant attitude after every time we call seasonally with problems, we feel that it's time to make this publicly known because who knows who else has had similar issues. If you do a little background check on his employee Michael, you won't want him at your house either! Anyone who wants to see this footage or pictures of proof- please feel free to message me! read more
