Brian Kraman

Super quick to set an appt and came over on a Saturday. 2 minutes to diagnose and 3 minutes to fix! Incredible. Craig even answered multiple questions for pricing on a replacement. AAA+++!!

Jeremy Scott

Cotes was very efficient and transparent. I wasn’t sure what to replace my heat pump with and lacked the knowledge of the options. They have videos that help with that and are very patient with explaining things. I also mentioned that I’d be doing more research and getting other quotes just like people should. They took no offense to that and were very respectful when hearing it. They worked with me on the pricing and terms, plus they are 24/7 with no night or weekend markups. Find another company that offers that. The installers were nice, friendly, and efficient. Great guys and service.

Business Response:

Jeremy- Thank you so much for the 5-star review!! We can’t thank you enough! –Cote’s Mechanical
