Cotti-Johnson HVAC, Inc.

Had an old ceiling fan replaced! Dan came and did a wonderful job including the electrical work! Brought ceiling fan up to code and replaced switch! The new fan looks amazing! I am very happy!

Excellent service! They came out the same day I called. David was knowledgeable, professional, and very thorough in his examination of the boiler. He gave me multiple quotes and options and even made some money-saving suggestions. I will definitely use Cotti-Johnson for any future needs!

Tim was our salesman and walked me through the first time start up. Very thorough and professional. Matt and Eric did an outstanding job installing our new Generac generator. They were professional and very willing to work with me to ensure the equipment was installed in just the right location. The placement of the generator, transfer switch and the wiring in between were meticulously installed. They cleaned up all areas before they left. They did a great job and I would highly recommend them!

My elderly dad is a proud portuguese man. At age 78 he tries to do home repairs on his own but he now knows he just needs help. Aaron is a family friend and I knew be would help my dad and be patient and get the job done and he did just that.

What a great experience. My dad was happy I stepped in and got this help. Thanks Aaron and Capreace.

The gentleman that came was very pleasant. He was through in going over all our electrical wiring. Fixed our light switches that haven't worked in years. Calmed our fears of an electrical fire. Would definitely recommend and use this company again. 5 stars

Daniel replaced a light fixture and broken light switches in my home. Really appreciate the great job he did as well as his friendliness and professionalism. He was also very knowledgeable and patiently answered my questions well about old wiring in the house. Also appreciated how responsive the company was and how quickly they were able to send an electrician. Would highly recommend Daniel and Cotti-Johnson.

Tim came out to do an estimate for service and was absolutely great to work with! Top notch service, friendly, and really tried to help us figure out exactly what we wanted and needed for the work to be done. Highly recommend!

Have used Cotti-Johnson a number of times now from fixture installation to entire house rewiring. No matter the size of the job, Sam/Matt/Eric and everyone else has been great to work with. Very punctual and communicative across the board. This most recent visit was to re-install ceiling fixtures after some plaster work and in the process Eric noticed a no longer used fixture wire in a side hallway out of view and offered to remove it and patch the spot. That kind of attention to detail is much appreciated and is not always found with other companies out there. Always a pleasure whenever we need to use their services.

First time using Cotti-Johnson and couldn't be happier. Had an outdoor spigot repaired by Joshua. He was extremely pleasant & explained everything so I could understand. Very professional. Very reasonable rates. Will definitely be using again!

Updating on 5/18/23 - they came out and did a thorough cleaning and maintenance on my 3 yr old heating system. Very professional, polite and explained everything clearly. Can't recommend them enough!

Exceptional service from the electrical team! Project included new breaker panel , meter, exterior power line, outdoor disconnects and dryer outlet. Meticulous professionals at a reasonable price. A big thank you to Tim Sokolowski and the crew. He went above and beyond to take down a metal star on the peak of the garage that has been an eyesore to me. An A+ experience from start to finish!
