I'd had several companies come to my home needing to convert my heating/air system but was not comfortable with either the representative or the estimates being provided. This was a big project for me and I did not understand it all even with doing my own research.
Once Ed visited my home and went over the services I felt an ease. He was easy to talk, very polite and spent the time, without a sense of rush, to answer all my questions and concerns.
Even after the work was complete I had additional questions about my loan. I call the office, speaking with Kait a few times and she provided all I

Ed and the folks at Conn are great. They came to repair my air conditioner the same day I called and ordered my new one the next day and installed it the day after that. I couldn't have asked for better service. Ed provided with me three options to choose from good, better, best and as well as a few different payment plan options. They went above and beyond to assist me and communicate via email and text. The technicians Eddie and Kenny were great. They were super quiet and polite in my house. They showed me everything and Ed stopped by the next day to check on the job and show me some of the controls

Conn Mechanical Services continuously provides excellent service. They installed my GEOTHERMAL System and provide routine maintenance along with emergency service (when rarely needed). They are always prompt when scheduling an appointment and on time when arriving for a repair. Nick is the repair technician that I have dealt with in the last year. He is very knowledgeable, professional and courteous. His knowledge insures that he detects the problem in minimal time while his professionalism results in the fast repair of the problem. Everyone in the company, from Ed Conn the owner, the office staff
