HVAC reviews in Hopkinton, New Hampshire

I was extremely pleased with my decision to hire Reassurance Plumbing, Heating & Cooling. Their service is not only prompt but also friendly and top-notch. I highly recommend them for anyone in need of reliable plumbing, heating, or cooling services!

nick is a top notch plumber, hvac ,oil and gas professional we've been working together for years . more to come

Great company to do business with!! Nick is a solid dude! Professional and great attitude!! Will definitely do business with again!!

Highly Recommend, look no further for your plumbing, heating or cooling needs! Reasonable, fair, communication is great and the work is amazingly done. Can't stress enough the quality of work you will get with Reasurance!

We had a minisplit installed by another plumbing contractor who clearly didnt know what they were doing we called nick , he scheduled us right away reinstalled the unit and had it up a running great service , very professional

Reassurance Plumbing and Heating has helped us with plumbing in a new addition, annual furnace cleaning and several emergencies that have come up unexpectedly. Most recent we found a leak in our basement. Nick Labbe was able to squeeze us in on a busy schedule the next day. He was able to repair in a timely fashion and be on his way. We could not be more pleased and he is our first call with all our plumbing and heating needs. Thank you Nick!!!

I can't say enough good things about Reassurance Plumbing. I have an old home with an awkward heating system. Nick and his crew were able to bring heat to multiple crawl spaces and for the first time since 1850 the house has full heat coverage. I no longer have to worry about freezing pipes even with the recent sub zero temps. Their prices are fair and the work is excellent. I highly recommend them to anyone with heating and plumbing needs. I'll be using them in the future for a master bed/bath remodel. Thanks so much guys!

Nick was great to work with! Nick was very communicative and showed up right on time for our scheduled repair. We’ve been having problems with our furnace since we moved into our house, and we’re so relieved to have those issues resolved thanks to Nick and his crew!

If you have any need for HVAC services call 603 Oil Burner Services. Peter and Kyle are top notch! When our water heater stopped working (Brrrrrr! 🥶) I knew who to call right away. Our call was returned, a site visit to evaluate the problem was made, and a new water heater was installed…all within 24 hours! We couldn’t believe it! They took the time to show us what happened and educated us on which product would be best for our home. Support a local and dedicated small business and call them FIRST!

Absolutely phenomenal work and customer service from Pete and Kyle!! I now won't even consider another company for my furnace and heating system needs. They came out on short notice (same day) to address some issues I was having with my oil burning furnace. They were highly knowledgeable and very professional throughout the service appointment. What put the experience over the top was Pete and Kyle's willingness to explain the process as they went and educate me on everything they were doing. Can't recommend 603 Oil Burner Service enough!!

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.

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.

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 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.

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 correctly. We are working on having them come out for something on more of an important customer education situation with the new system to keep it at its best, and are working to get an app't soon all the while in between this extremely cold Winter! But they have been responsive and really care to keep the customer connection! Something you don't always see these days. Thanks 603.

Kyle and Pete are absolutely fantastic! They are family run and operated and are top notch.
They installed a new boiler for us years ago and are now our “go to” people. They are fair priced, trustworthy and incredibly professional.
If I could give them 100 stars I would!
