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 Peters and Kyles (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.

I called my local oil company after waking up to find my furnace was not running, and I had already tried most of the resets and basic homeowner stuff with no success. They could not help me, and the service people they suggested wanted almost a mortgage payment to stop by my house just to see what the issue was. After a quick search, I located 603, and they were close by. I called them and got a real person who said he would be happy to help. He came right over and arrived when he said he would. Super personable and beyond qualified. In no time, he had figured out the issue, cleaned and repaired my entire system, and fixed a long-running hot water issue. And in the end, he charged me a fair price and offered follow up service if needed. I cant say enough about this company. If you are in the Hillsboro area and are looking for a quality HVAC service company, I can highly recommend 603! They have truly earned my business, and I already have them on my calendar for next years service. Other companies should take a page out of their customer service approach. Truly a blessing this Holiday Season. Andrew W. Henniker, NH
