Cotti-Johnson HVAC, Inc.

My service man David was informative and courteous. He repaired and replaced the Posi-Temp control in my shower. He was fast and very clean when the job was completed. I will choose Cotti-Johnson for any future plumbing repairs. 5/18/23 Somerset, MA

The plumbing division at Cotti-Johnson is fairly new, but you would never know if from the absolutely first-rate job that they did. It helps that the people they've hired bring a wealth of experience to the job. Aaron, Aaron, Josh and Dave installed a reverse osmosis water filter for us, removed an old concrete sink from the basement, and swapped out cast iron pipes for PVC. Aaron Silva oversaw the job. His online reviews (from before he joined Cotti-Johnson) made him sound stellar, and he is. His estimate was fair and his professionalism lasted from start to finish. Josh, who worked under him, was willing to let me learn a little from watching the steps and was very friendly explaining stuff. All in all, a great experience.

Tim was great! I had some electrical repair work and ceiling fans installed. He listened to what my concerns were, he was knowledgeable and happy to answer my questions. After checking everything out he gave me several options to choose from and encouraged me to choose the option that I felt was best for me. After the work was completed he walked me through everything. He explained he membership program and I signed up immediately. It was well worth it! I've also used Cotti-Johnson for hvac and other electrical work and I've been happy with all of the work they've performed!

They rewired our old house, bringing it up to the standards and codes of the 21st century.
The electricians were professional, friendly, knowledgeable, clean, and prompt. We would DEFINITELY use Cotti-Johnson again!

I my tub was clogged for a few days and Josh came extra early to see the situation. It took him about 30 minutes to explain to me what was happening and snake the tub. He did a great job. I would for sure recommend this company to my neighbors.

Daniel and Jayron where very professional and polite their work is awesome so happy my light finally is up thanks guys

Courteous, Friendly, Caring, Informative, Professional, Skilled, Knowledgeable, Respected my home and myself, Went about solving my issue within minutes and did so with a smile. Can not say enough good things about the Cotti-Johnson electrician and Cotti-Johnson as a company.

Tim Prouix from Cotti-Johnson was terrific. I was incredibly impressed by not only his professionalism, but his creative thinking about solutions for my generator replacement couldn’t of been any nicer or smarter.

He’s a great asset to the company and I’ll definitely use his company for other upcoming projects

A really terrific customer experience

Matt and his colleague dis the installation today, and they were equally terrific, personable, and couldn’t be any nicer

Outstanding service and very professional. Technician David, corrected the slight leak in our garage from our master shower. Would highly recommend this business. From the office staff to the technician..Outstanding service. Thank you!

Tech came out at midnight and evaluated our electricity issue quickly. And had to deliver bad news, but did it in a comforting way!! Very professional and knowledgeable.
