603 Oil Burner Service Heating & Cooling

We are not people who usually write reviews, but the service that Pete and Kyle offered to us was above and beyond what one would expect. Right from the start they showed up on time!! Phone calls were returned in a timely manner! They made the experience of having to replace our heating system as seamlessly as possible and with total pride taken in their work. Absolutely awesome. So happy we had their service. We will have them out for other work we may need here in the future. Thank you so much Pete and Kyle!! Update: February 2026 These guys continue to show care and concern towards their customers! On a personal note, they checked in on us during a recent difficult time after a couple of losses! They stopped in and made some time to check in and see if the new system's up and running

Peter and Kyle provided timely and compassionate service, and were very informative. They took the time to answer my questions and provide additional information I was curious about. They clearly care about and prioritize their customers. Great local business!

603 Oil Burner Services installed my new heating system in Hanover, NH in December 2023. I selected this business after much careful research. I am impressed beyond belief with Peter’s and Kyle’s (the business owners) high standards of professionalism, honesty, workmanship, expertise, and total commitment to making my experience the very best possible. Peter and Kyle never promised the least expensive oil burner system and installation. They did promise to provide me complete information the make reasonable decisions in terms of brand of boiler to purchase, etc., and high quality work and service. Peter and Kyle repaired major problems with my radiators that far exceeded expectations at the time my contract was signed, and did not charge me for the extra work. I am convinced that had I gon

On what was going to be a weekend of severe cold, our primary radiant heating circulator died. Called 603 OBS and they arrived within a few hours with a replacement circulator. Heat was flowing within the hour. Can't say enough good things about them.

Kyle and Peter are the best of the best. I called them after being unable to get anyone out to service our furnace. They were very easy to communicate with, prompt, and were able to fit us into a busy Fall schedule. They both took the time to educate and involve me in their process. It's clear that they care about the work that they do and their customers. They are a real, kind father and son team. Cannot say enough about these guys.
