What Our Clients Say

Testimonials

Had a great experience with this company. They came out to diagnose and fix our AC unit this month. Daniel G did the diagnostics last week and Kevin F came today to fix it and replace our pump. Both were extremely professional and knowledgeable.

Also, Mo and Niel came for a plumbing issue a few months later and did a great job diagnosing the issue. Very friendly and professional.

As usual, Paul did an excellent job. The new electrical wiring is great and with the clean-up, you would never know he was here.

I had my heating system checkup today. The technician was courteous and professional. I really like the way this company operates.

10-20-25 I called to find out why my a:/c fan was coming on when my heat came on. The technician came out and discovered my thermostat was set up for electric heat vs gas. He set the thermostat for gas and the fan no longer comes on for heat. He was very courteous and knowledgeable.. I asked why my a/c filters seemed to not fit. He showed me that most filters for a 24x30x1 opening are sized at 23.5x 29.5x3/4. I have searched for 24x30x1 filters and can’t find any..

7/31/26 I had N H Ross technicians come to my house to install new light over garage door. They also hard wired the light switches that are no longer needed. Very courteous and professional as all of Ross technicians have been. I am so happy that I found this business.

Kit Covington

I would like to give a review on Mike Decastro. Mike has been with NH Ross for a short time but an electrician for 12 years. He is excellent in his job and extremely neat. The job he performed was a bit difficult having to go in a small attic to do the job correctly. NH Ross is lucky to have this electrician working for them.

Nancy Cavallo

Cole was great. He installed a whole house surge protector and GFCI switch in laundry room. Cole explained everything clearly and did a great job. Would definitely recommend this company.
