“We have been using Hatfield Brothers Mechanical for years! Great service and pricing. Bob and Matt are honest, reliable, hardworking guys! I highly recommend them for any of your plumbing or heating needs. They installed a complete system in our home and have done other repairs and service.”

– Salem, NH


This company is awesome. I had them put in a furnace for me. Very dependable, reasonably priced and very professional. I was impressed with their workmanship and how clean my cellar was left. Matt was extremely knowledgeable and answered all my questions. I referred their company to others and I was told they were happy with the referral and would use them again.

Hatfield Brothers Mechanical has maintained my home furnace for many years. They have extensive experience in the Heating and Air Conditioning field. They have performed many maintenance repairs on my furnace and I have never been disappointed with their quality work. They have most repair and maintenance parts readily available on their service vehicles, so there isn’t a wait for parts. This is good when my furnace stops in mid- Winter. In an emergency they are ready to help. Thank you Hatfield Brothers for being there for me.... :)

Had Matt come out when we first moved in our house to replace our furnace. He showed up when he said he was going to and got right to work. Him and his team were polite, knowledgeable, professional. We recently called him again to move our ac unit, again they came right out and quickly got it done. I would highly recommend Hatfield brothers.

Matt and his crew installed our new furnace after ours failed. They were great! Timely, clean, and professional. After the install Matt kept in touch to make sure everything was working well and if we had any questions. Fantastic job! Couldn’t be happier.
