We had J&M install a Bosch mini-split system and have been very happy with it. It runs a lot quieter than I thought it would. After the install they did a great job cleaning up the site and did a great job answering any questions we had.

They did an absolutely amazing job on my HVAC system. I recieved a new furnace that's located in my attic and a new ac unit that's located on my metal roof. They took their time. The contractors that came out were very knowledgeable. The other contractor that came out to build a new attic staircase did an amazing job also. One of the contractors even went out of his way to seal a spot on top of my roof that he seen rain water entering in. They were the nicest contractors that I've ever met and they were FOCUSED. I couldn't thank them enough. Thank God for an overall great company, from the performance, to the knowledge, to the respectfulness of the contractors. You just dont find reliable companies like this anymore. Thank you J&M.

My husband was home when Mitch arrived. Apparently determined the problem quickly, because Mitch knows what he's doing. Replaced the selenoid. Humidifier working. Grateful. Cats no longer getting electrocuted, which is a plus. Thanks, Mitch, very much!

The furnace was not working and it was only 5 degrees outside. They made me the first appointment and and got it running by lunch.

Called about furnace issues and they were able to get me in on the same day. They’re definitely awesome and plan on using them for any more issues we might have in the future.

Mitch was a great help and got the heat switched back on ASAP. Would highly recommend J&M for your residential needs.

Mitch came to fix my home furnace which had been out of service for several days after a power outage. I had called six other businesses and they either did not service "modular homes" or weren't available till a much later time.
Mitch was prompt, he was courteous, and thorough! He not only fixed the damaged piece on the furnace, but he changed the furnace filters, and replaced the old thermostat with a more up to date one which was wonderful.
I was expecting a much higher bill. But because he knew what he was doing, he was in and out quickly and efficiently.
I've already shared his name with some friends and family for "just in case"!
Thank you J & M Mechanical, for your help today!

These guys are lifesavers and installed a furnace for me right before a snow storm. They have done great work, and are very competitive with their pricing.

We have gotten service from J&M on multiple occasions including a recent AC replacement. They are very good in terms of communicating and their turnaround time from call to visits and estimates have been great. Highly recommend.

J &M Mechanical returned my phone call within the hour of e leaving my message. They were at my home in just a few hours to get my furnace up and running. Great customer service and quick to get the job done! I highly recommend them for any job you need done!

Our air conditioner stopped working mid-summer heatwave. J&M Mechanical came out quickly, gave me a FAR more efficient unit than another local company offered AND they’re super friendly! Installation was quick and efficient; show up when they say they will and complete the job as promised.
We support excellent family owned, local businesses as much as possible and these guys are awesome.

After a very bad experience with two different local HVAC guys a couple years ago, I realized I really had to replace my house's dinosaur heater. I found J and M Mechanical well rated and well reviewed. They lived up to the excellent evaluation for me, and within 10 days of inquiry had the job done and done well despite this old house's many furnace and duct work oddities. They are punctual, honest, and keep you informed. The actual installation took perhaps a total of only 8 hours. They also clean up after themselves and are hood guys. I give them my highest evaluation.

Our experience with J&M was fabulous. Mitch was very professional, quick with his work, and very thorough in explaining what was going on with our A.C.

Of course one of the hottest days our AC went out after hours
They set us up with a service the next morning (we were going to suffer the 80* night) and he came earlier then expected (of course calling ahead of time) and got us up and running again

Our air conditioner had gone out & Mitch was able to schedule us in for the same day. He was on time & very professional. I was very impressed when he texted me to let me know he was on his way. He found the problem & fixed it in a short amount of time. Very impressed with whole experience. Would highly recommend J&M

Mitch came in and got an exhaust leak repaired immediately after I was not able to get the person who initially installed it to do the repair work. During his inspection he found our gas line wasn't to code and took care of that issue along with repairing and replacing the pvc piping that was not done correctly by the previous company. He was very explanatory about all the ins and outs of our new equipment and got us taken care In a timely and professional manner. Thanks to him our furnace is fully operational and we have no more leaks and none of us are sick anymore. I would 100% recommend him in the future and we plan on keeping him on call for any of our needs that he can address. Thank-you for getting us taken care of!

Our heater stopped working properly during the coldest spells this winter, JM mechanical came over with in a day to service and was able to diagnose that our heater was in need of replacement. Within 2 weeks they were about to order and install our new heater and we decided to add onto it the AC unit as well. They always left their shoes at the door and cleaned up after themselves. Both were knowledgeable, polite and professional. I would recommend them.

J&M is professional, knowledgeable, responsive and quick. They installed a new furnace in our older home earlier this year and recently installed a new central air unit and thermostat. We’ve had no issue with our furnace and our air works wonderfully. Highly recommend.

They were on time and friendly!! They took the time to look at my A/C unit and all the checkpoints along the way. Also, spent time explaining what they looked at, and provided options on how to make the upstairs of the house cooler as it turns out my A/C is working as it should. They also hooked up the natural gas line to my Blackstone!! Prices were as expected. Would recommend. and will use again!!

Prompt service at a great price. Nothing like the other contractors in town, they actually do care about their customers.

I would like to say a huge job well done to the owner of this amazing company Mitch Pias for installing a new AC unit super fast, efficiently and at an amazing price, our summer will be much much more enjoyable! I would like to add that our house had central air but no one and I mean no one in this area was able to get it repaired or up and running properly in 18 years- yes, I said 18 years, and 100s of dollars and J & M has me up and running in 1 day. Just Amazing, great job Mitch!!!!
