We had contracted with this company in 2016 to look at solving an in-floor heating problem. J&S completely revamped our the copper and undersized boiler and it has worked well since. Fast forward to the summer of 2022 and we called J & S Mecanical again to look at our 17 year old A/C & heating systems. Both furnaces and A/C units were replaced at a fair price and they're nice to deal with. We highly recommend them.

Eric & Jason were phenomenal to work with. They went above and beyond to figure out and replace our complex system with an energy efficient system that works perfectly for our needs. Their knowledge and expertise were unmatched in this industry. They were available with questions and didn’t hesitate to spend time making sure we understood the new system. Men with incredible hvac knowledge and integrity, a winning combination. I would HIGHLY recommend them.

Our AC stopped working during record heat in early June. Since we have Home Service Plus, I tried to get an appointment but the first available was several weeks out. My neighbor gave me Jerry's number and by the end of the day, our AC was working. That is service! The amount they charged was very reasonable, when they could have charged a premium due to the high demand. I highly recommend them and will definitely be calling them when we are ready to replace our AC and furnace.

J & S Mechanical Inc. Our AC stopped working on one of the hottest days of the year. Service Plus was booked 2 weeks out. My neighbor recommended J&S so I called them and the AC was repaired that same day! Great service for a fair price. They will definitely be our first call for any HVAC needs.
