Greg R.
Google Review, AC Installation
MJM was very responsive for our heating/AC commercial unit that had failed after 22 years. John was out the next day and supplied a quote that evening for all the work and cost of the unit. The install went quickly and a follow-up phone call to ensure everything was completed as promised. Steve and crew did a great job finishing up the install with thermostat.

Google Review, Furnace Repair
I have used MJM Mechanical multiple times. I usually don’t leave a review but I have to say this company goes above and beyond every time! I called them the last time because my furnace wasn’t working and their technician was amazing! He was thorough and very detail oriented and walked me through all of my options. I’ve never had a company go so far to make sure I was completely satisfied. It’s nice to have a company that puts a customer first in our town! I highly recommend them to everyone!!!

Facebook Review, AC Repair
John was a lifesaver!!! We bought a house and the day we closed the AC wasn’t working. I got in contact with him and he came over tonight and had us up and running in a couple hours. Reasonably priced, reliable and kind. We will be using their services for regular maintenance. I highly recommend them. We were very lucky he was able to come and help on such short notice. Five stars.

Google Review, AC and Furnace Replacement
I got multiple estimates for a new Furnace and A/C for my home, before being recommended MJM by a friend. Their estimate came in lower than all the others (significantly lower than some companies), and they had still had the top of the line equipment I was expecting. The service technicians were prompt, friendly, and answered all my questions. I would HIGHLY recommend MJM Mechanical to anyone shopping for a new HVAC system.

Google Review, Boiler Repair
Brandon was excellent! He came out to our home for boiler work and diagnosed our problem better than ANYONE from other local businesses! He took the time to show me and explain how to keep up on maintenance for our system and actually cared. Will definitely use again!
