Dedicated to Quality Equipment & Workmanship

We provide affordable and quality HVAC repair and installation services to customers throughout the Chicago suburbs.

I would recommend MJ Mechanical they were very helpful for giving me advice on what to do to fix my problem and not pushy to sell anything at all.

We had MJ Mechanical install a new air conditioning system including furnace and complete duct work in our home. My husband Bob worked in the trades before retiring. He and I were very pleased with the service and workmanship that we experienced. Adam and Andrew were first rate. We would be happy to refer anyone to this company. Thank you for a job well done.

I want to recommend MJ Mechanical LLC Heating & Cooling for their services. Contacted them on Sunday night due to an air conditioning repair situation. Adam showed up on time, troubleshoot and identified the problem in a short period of time. He gave me an explanation of costs up front and only replaced the parts that were necessary. He was awesome and highly recommend him and MJ Mechanical. Kudos to them from a very satisfied customer!

Excellent work. Done in a day and a half. They did the paper work to get $1K in rebates.

Absolutely awesome service! I was having so many problems with my previous heating and cooling service provider, and MJ Mechanical solved all my problems. The technicians are knowledgeable, efficient, and friendly. Drew was able to tell me what was wrong with the unit in addition to showing me as well. It’s great when you can see the problem and not just have to trust what someone is saying. They also took the time and effort to educate me on my unit’s warranty. Great service great price!

I can’t say enough good things about MJ Mechanical. They are professional, efficient, hard working and extremely reliable. We’ve had them out for service calls on our furnace as well as our central AC and they had us back up and running in no time (without emptying our wallet). When it came time to replace our furnace and AC at the same time (ouch), I knew I could count on them for a fair price and a painless installation. They even fit us into their schedule with lightning speed.

The staff at MJM also went above and beyond, to make sure we had all of the information needed for the rebates that were available (we’d never have known the rebates were out there, if not for them)- and it saved us $900.

We are so happy with our new furnace and air conditioning system. We have peace of mind knowing we got the best system for our home, at a fair price, with expert installation. I would recommend MJ Mechanical to anyone.
