If you’re thinking about using this company, don’t. They have you sign an agreement service contract “to lock in the price” right after installation. The next year they don’t honor the service contract cause the prices went up. It’s one of the well known bait and switch schemes on earth. Besides when they install they omit a key option you request and they say oops, sorry. Find another company which honors their work, you’ll be happier.

By Angela E.November 24, 2020Repair heating system
In the last couple weeks there have been some chilly nights and cold mornings. I had no heat. I just happen to be looking on line to get help. I came across Cotti-Johnson HVAC. I did a quote request and received a return call back. I was scheduled an appointment and then the gentleman kindly explained the Protection MAINTENANCE PLAN which was an Awesome deal.
Today a technician arrived to my house to assess my heating situation. Not only did he fix the heating problem, the technician was able to give feedback to other concerns, 2 radiators not working and also informed me that my hot water tank is out dated and will need to be replaced at some point.
The technician provided Excellent service, was very detailed and professional!!
Thank you so much... -

I have mixed feelings about Cotti Johnson. You needed to stay on top of them. They scratched the hardwood floor upstairs and leaving that up to me to fine someone to refinish it. They said they would pay for it but of course can't fine anyone to look at it never mind repair it. They ended up doing the install down stairs twice. The duct work was so low, but the end result came out good.

I had a severe neutral line crash . The only way to describe it is to say that it push 250 bolts through out the electrical wire in my house. It was a Big Bang the wires in the house were likely fried. Cotti-Johnson son came immediately. They check every wire, outlet and switch. They diagnosed the problems and fix them that day. I had to call them back for one switch that was complex and difficult, but they came the next day and fixed it. There were s little pricey, but I am old and my ideas of reasonable lay back 40 years ago. Needless to say, I would recommend them. Professional and courteous and efficient.
