Cotti Johnson HVAC, Inc.

BEWARE OF THIS COMPANY I purchased a brand-new heating system for $15,000 in September 2025. The system came with a one-year company warranty in addition to the manufacturer?s warranty. Despite being new, the system malfunctioned four times within less than six months ? on December 4, December 6, December 17, 2025, and again on February 14, 2026. Why would a brand-new $15,000 heating system fail four times in less than six months? Each time I called the company, the response was slow. I later learned they do not provide evening, weekend, or emergency service. This was during the heart of winter, and I was completely at their mercy to service a system that was still under warranty. When I requested to speak with a manager, I was consistently blocked. The secretary or office staff always had an excuse as to why no manager was available. There was never an opportunity to address my concerns directly with leadership. The company presents as polished and professional when selling the

On time and knew his stuff. Thank god for him.

professional; price a little hgh

August 2025 - we’ve had the unit serviced many times since ‘22. All professional, o formative & knowledgeable. Zach is our tech today: again, super! Thanks Cotti Johnson and your employees who keep us cool in summer! Thanks to Melissa, Paige & Nancy in the office too! Update 4/13/22: Troy Butler & his partner came to service/check unit before summer use. Professional, on time, again 5 stars! Ordered a Mitsubishi mini split AC. Install delay was on us as we needed to upgrade electrical. Company’s electrician worked with us the following month. Installers on time, efficient, great communication throughout install and they gave a good demonstration as well as going through the manual. Highly recommend: all communications were prompt & professional from Mel in the office to electrician and installer. Highly recommend. J Forgeron returned 12/17, earlier than expected 👍 to take care of a small item identified by the local electrical inspector.

I bought a new electrical service and generator from Cotti-Johnson. They explained everything in detail and arranged a loan for me. During a major storm this December 2023, when I needed to check my oil, their tech called me multiple times. He walked me through the procedure. I was able to open and make sure the generator would function after a 24 hr of operation.

Replaced Ring camera, installed towel warmer. Offered home electrical eval. Prompt, friendly & professional. In 4/2025, Josh did a thorough plumbing checkup. In 5/2025, Jim did a fine job maintaining our HVAC system. 8/2025, JT replaced my EV charger; excellent service

Very experienced -very thorough -very professional and very knowledgeable. Jim Cyr is Highly recommended

Called them to give me an estimate on electrical work in my house. They attempted to do work I didn't ask them to when they couldn't get my breaker to flip (which I flipped many times without issue) they procceded to put pliers on It AND SNAP IT. Broke my stuff and still charged $59 for their consultation. Unprofessional. Told them over the phone, and they don't care. Don't hire them, hire anyone else.

They did a great job. The electrician was able to identify the problem and came up with a solution that was reasonable and resolved the problem. I would hire them again.

On time. Patient got the job done well
