Inspection of plumbing and flush-out of water heater. Todd E. gave a very thorough inspection and made recommendations for future upgrades. I was very satisfied with the service and was confident of the report and recommendations made. Polite and expert service, would highly recommend.

Daniel was the first member of NH Ross to come repair my HVAC system after the AC stopped working over the summer and was flooding the utility closet with water. He did not rush, walked me through each problem and educated me, was professional and polite - great experience! I’ve had such horror stories with contractors on the past and I now feel comfortable knowing I have NH Ross to rely on each month.

Beyond that, I then had Eli and James come for my annual free time up of my heater. Having moved in only a few months ago, I was totally unaware of the lack of upkeep from the previous owners. Eli and James diagnosed everything, explained the problems thoroughly in layman’s terms, went above and beyond to fix ancillary defects, and provided a full repair within under one hour!

This company is fantastic, I highly recommend them to anyone. Communication and scheduling with the office is a breeze. I’ve had the worst experiences with techs and NH Ross has been a rock star!

Since I am unable to leave more than one review, I’ve edited this one to reflect my recent experience with their plumbing technicians.

I had an emergency and Todd was able to fix everything quickly, efficiently, and explained everything to me in terms that were easy to understand. The price was very affordable and he was great to work with. He also gave me great advice on how to avoid future problems.

Mohammed just completed my annual plumbing tune up and went above and beyond! He took his time and walked me through everything. Pleasant demeanor, professional, and worked so hard! Every experience so far has been terrific! Thank you!

Once again this company has done a phenomenal job! This is the second time Rich has come to fix plumbing issues in my home and like everyone else he was quick, efficient, friendly, and very professional. I appreciate him taking the time to check extra things and explain everything to me. Thanks again!

John came to flush the RINNAI water heater for its yearly flush but my main concern was I smelled gas in the house from time to time. I had other plumbers come and check it before and they never found a leak. John went in the crawl space sprayed the pipes but didn’t smell gas in the crawl space but only in the stove area he kept looking for where the gas smell was coming from and he found it! A bubble formed from the bottom of a pipe. He put in a new one pipe triple checked it to make sure no gas was coming out of it. John really was like a bloodhound to find where that gas leak was coming from.

RH Ross heating converted my oil burner to gas. They did a beautiful job. Recently I've had them do annual maintenance on the unit by their service man John R. He was personable, thorough, and provided details on everything he did. It was a pleasure having him take care of my system and I look forward to the next time seeing him.
