Technology has vastly changed the nature of the HVAC Industry over the past decade. The equipment is more advanced than ever presenting constant challenges for companies in training their technicians. We have invested in a training center where our technicians can get hands on experience with the new technologies and keep their diagnostic skills honed. Our customers benefit by having technicians spend less time resolving their problems and by having it done correctly the first time.

Our commercial customers also have the advantage of MJ's maintenance services. Our agreements can be as flexible as providing technical assistance on an as-needed basis to a more comprehensive program of scheduled routine maintenance.

We specialize in HVAC equipment inspections and installation. MJ Mechanical's Commercial HVAC Service Department is qualified and experienced in troubleshooting and solving air conditioning service and repair.

If an HVAC equipment repair is cost prohibitive because of its age or poor efficiency, we offer equipment replacement and upgrades for packaged units, split systems, chillers, cooling towers, pumps, boilers, heat pumps and A/C control systems.

MJ is experienced in both small and large Heating, Ventilation, and Air Conditioning (HVAC) systems for our commercial and industrial clients including refrigeration equipment maintenance.

MJ's Commercial Service Department operates 24/7 to perform service and repair.
