What Our Clients Say

Testimonials

Really great service and professionalism.
Jeff Rohwer
Todd was a great help. I will request him again next time we need service
Suzanne Hogan
Cole. T was very pleasant, detailed and thorough. Highly recommend.
Jovia Bowes
Paul P. did electrical tune-up and comprehensive bringing everything up to date and functional. He was incredibly customer service oriented. Went over everything in detail, answered questions, pros/cons of options, and then took care of things with great attention to detail. I could not be more satisfied

Update (June 2026): Worked with HVAC to have a heavy duty dehumidifier installed; the technician (Eli) was informative, detail shared all the options with pros/cons to help me with various decisions, and professional with install and instructions. Also had Electrical do the annual whole home electrical system checkup. The technician (Klivan) was prompt, polite, and went above and beyond to answer questions. The checkup was pretty much straight As, which supports the quality of electrical work performed by NH Ross last year.

Anthony J Novellino Jr.
Brian explained everything about the HVAC mini-splits checks and cleanings he was doing; he vacuumed my system clear of accumulated debris; tested each one for efficiency and pronounced my FUJITSU HVAC system in perfect shape. Brian was hardworking, friendly, and answered all my questions & concerns. NH Ross is fortunate to count Brian as one of their employees- a great representative for the company!
Peggy Drowns
Tech was great! Knew what he was doing. Left house clean. Highly recommend!
Michelle Petzolt
Both gentlemen did a great job! They were very professional and well spoken. Everything was explained to me during and after the process.
