DNR Services

Courteous, clean & professional, and their pricing was competitive as well. They hauled out my ancient gas boiler and hot water heater, and installed a new high efficiency combi-boiler for me. Denis was very patient and informative in answering all of my questions, and talked me through the new system & recommended upkeep once they were finished.

100%! Great price. Replaced our Geo ground loop heat pump and well pump in short order. Left everything clean and working as it should. From first visit to job completion, delightful experience all the way around. Highly recommend.

We have used DNR a few times for HVAC related repairs and each time they were great! Very friendly and knowledgeable technicians. Would highly recommend

The DNR team were excellent to work with. We had a large and complex job to replace our entire HVAC system. Their pricing was very reasonable. Maks and his team completed the job in a timely manner, clean, tidy and efficient. Highly recommend DNR for any job…big or small. Great team of professionals.

Late in the afternoon on a frigid Wednesday my tenant called to tell me that their heat wasn’t working and only blowing cold air. The tenants have a baby and the temperature was dropping to 12 degrees that night. I contacted a handyman friend but he was unable to fix the problem. Luckily he suggested Denis ar DNR services. I placed a call and within minutes Denis returned my call. By 7:30 that evening Denis arrived and diagnosed and fixed the problem. I was so relieved and impressed by his prompt and courteous service. Although it was after hours his service was prompt and courteous and extremely reasonable. I highly recommend his service.
