Kevin, who has worked in this business for many years and is extremely knowledgeable about energy-efficiency and environmental improvements, shares his expertise with his son, and it’s a pleasure to see them work side by side. We were referred to Kevin and Sal by our nephew, who had found them on Angi’s list when he needed a new boiler.

Joe was on top of everything from contacting me when he couldnt make the original installation date, to following up and waiting on me to have the electrical upgrade, was on time and punctual both days its took to do the work and made sure he explained everything and I had a clear understanding of everything. I would definately recommend and hire again for any Hvac needs"

"I am very happy with Mikes Air Conditioning. Here it is JULY and I while in the middle of doing some renovations to my home, I noticed the AC wasn't working the way it should be. I contacted Mike's (fearing the worst) and they sent out a service technician who was able to repair the system for a reasonable cost and buy me some more time before I have to replace the entire system. I had some minor work completed and the freon topped off and now I'm cool and comfy!  Considering all of the expenses with renovating I was very happy to not have a high repair bill. Mikes was efficient, conscientious and professional and they completed the job on time and for a reasonable cost. I recommend them for AC repair as well as installation of new units. When I'm able to replace my system, I'll be calling Mikes Air Conditioning to do the job. Building relationships and getting repeat business should be the goal of any business. I'm glad to see that Mike's takes customer service seriously.
