Many thanks to Jason and his MJK team for their great service! MJK came highly recommended from a trusted contractor, and we couldn't be happier with their service. After an emergency call, Jason was on site within 24 hours and had our air conditioning back up and running in no time after an electrical issue. Jason was incredibly knowledgeable, despite never working on our units, and we appreciated his patience in explaining with great detail exactly what went wrong and his plan to fix it. Professional, honest, and left the job site in pristine condition after getting our units fired back up. Sincerely looking forward to working with Jason and the MJK team in the future as our trusted HVAC contractor.

Had some issues with my AC condenser recently and called a few contractors. By far the most responsive was MJK Mechanical. Even better, when they arrived they were professional, courteous and quick! AC was up and humming in no time for a very fair price as well. Great people to work with and would recommend them to anyone.
