Customer Reviews

“Excellent experience. I have been doing business with CPS for more than 20 years and, as always, they were prompt, friendly, explained everything in terms I could understand, and left things clean. Curtis was great.”

Ron J, Newton, MA

“I have worked with CPS for many many years. It is the only company I use and the only company I recommend. Very professional and I never worry about the quality of the work.”

Paul M, Cambridge, MA

“…We could not be happier with our new system and with your company. It is not often that you find a product that works and a company which is wonderful to work with, and for this we say thank you.”

Elizabeth, Bellingham, MA

When a company provides courteous, professional service, it deserves to be recognized, and so do the people who provided that service. I’d be happy to recommend you to anyone who needs HVAC service.

Melinda, Ashland, MA

Alexis and Hope visited our home for our HVAC service today and I cannot thank you and your team enough for having such professional, courteous, and capable technicians… If technician requests were possible I would request their service every time! I just cannot say it enough, it was such a pleasure working with both of them today… We are exceedingly grateful, looking forward to continuing our work with you and your team.
