603 Oil Burner Service Heating & Cooling

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 gone with a large company (e.g., the company that supplies my heating oil), I would not have received as much value for my investment.

These guys did a great job servicing my propane boiler. It was headed for a breakdown and now we are ready for winter. Professional work at a fair price.

Spoke with owner about propane conversion for our dryer. He was super responsive. Sent technician to do the conversion. Kyle was very respectful, knowledgeable and friendly. I’ll definitely be using 603 OBS again!
