It was a pleasure working with Mike from MGM to get mini-splits installed. He took the time to explain the options I had, costs, and rebates. He brought a diagram along to illustrate the size the units would be which helped greatly to visualize them in the space. He worked to hide the cabling needed in my closets so that I had a clean finished look. The two gentleman who installed the units were polite and efficient. They worked hard and you barely knew they were here unless they asked a question. They were also through and made sure I knew how to work the systems before they left.

Top-notch customer service and extremely knowledgeable! You won't go wrong by choosing MGM!

I have been using MGM for years for a home and a couple rental properties. Anytime an emergency comes up or maintenance in general they are always on top of it. Exceptional work!

MGM Mechanical installed a mini split system for me two years ago. They recently serviced the indoor head units. The employees are always very professional and friendly. They do a quality job and make sure they keep the job site as clean. I would recommend them to anyone looking for a new system or need service for an existing unit.

My outside A/C unit died on Monday evening and I texted MGM and received a prompt response about it. I explained the issue and Mike was fairly sure he knew what the issue was. He said he had a technician in my area Tuesday morning and they be there first thing in the morning. The technician arrived first thing Tuesday morning and quickly diagnosed the problem. He explained the problem to me and was able to fix the issue immediately. He went further and to make sure nothing else was wrong. Couldn’t be happier with the service, MGM mechanical is an excellent company with second to none employees. If you are looking for top tier service or installation of mechanical equipment you need not look any further.

Prompt and competent. A job well done!

Always responsive and techs are top notch!

Air has a burnt smell: A burning smell coming from your heater may indicate a dirty air filter, an electrical problem, or an overheating component. We’ll thoroughly inspect your system, find the source, and get your system fixed in no time at all.
