In short, great work! I had received a few other proposals to fix, improve, or replace an inadequate air conditioning system in a split-level midcentury home. All the other proposals would have cost astronomically more and/or didn't seem likely to work. After essentially throwing up my hands, I was referred to Mike/MGM by a real estate professional. The initial visit was great for explaining the options as well as ruling out a variety of bad ideas. And the ultimate recommendation seemed very reasonable and to really address the problem. Scheduling and work went very smoothly and according to plan. The air flow and temperature have been wonderful (from testing it out for several days of unseasonably warm weather). In sum, I recommend Mike/MGM strongly and without hesitation.

I contacted MGM Mechanical for an estimate to install heating in our basement. Mike came to my house the same week and gave me different options along with the estimate for what I selected. He also was able to begin the work when I needed to have it done. He was very knowledgeable and competent and kept me in the loop on what was happening. The day before he was to arrive, I noticed our hot water heater was leaking. I called inquiring if he would be able to install a new tank while he was here. A new water heater was delivered the next morning and installed along with the new heating system. His men were very kind and courteous. They also were very clean and wore covers over their shoes. After the work was completed, they thoroughly explained how to operate the new system. MGM's estimate was lower than I received from the company that I have been dealing with for the last 30 years. I will certainly recommend MGM Mechanical to my friends and neighbors. Also, I was able to receive a $700 rebate and they completed and sent in all the paperwork for me. It was a very easy project and I am very happy.

Mike and his team are great! Mike worked with me to find an affordable heating and AC system to replace my 18 year old system. Mike was very patient with my all my questions and extremely knowledgeable about everything HVAC related. The install was also a great experience as well. Meade and his crew made sure I was happy along the way and they didn't rush through, they definitely took their time making sure things were right. I would highly recommend MGM Mechanical to anyone looking for quality work at a reasonable price.

My wife and I were in need of a good dependable furnace man that would provide repairs and servicing. When we heard about Mike and his company (MGM Mechanical) we made contact and we were very glad we did. When we make a call to request services, Mike is very reliable to return our call to schedule. We had our furnace go down this past year on New Year's Eve Day and Mike came out and made the repair. We highly recommend this company to anyone!

Our Fire Company was in need of several different services with our furnaces as well as purchasing several mini-split systems for heating and air conditioning. MGM not only was able to fill our needs by installing a double head mini-split, but also was able to bring our older model steam oil boiler up to State codes. They not only completed these measures, but they also were able to come out and do immediate repairs when our station had no heat. We will be using MGM for the years to come and highly recommend them to everyone!

I am pleased to write the following letter of recommendation for Mike and his company, MGM Mechanical. I have been a client of Mike's for over five years. I initially hired him to help manage the heating and cooling needs in my business and I now use him for my home. He has provided me with regular maintenance service and emergency visits when an old heating system in a rental property stopped working. He recently installed new systems into my rental property and repaired a faulty installation of my own air conditioning system.

In all my contacts, Mike and his men have been timely, thorough, and efficient. His cost estimates have been very reasonable. He has been responsive, reliable and honest in his dealings with me.

I do not hesitate to highly recommend MGM Mechanical due to the quality of their work and the reasonableness of their cost.

We are very grateful to Mike and his team at MGM Mechanical. Over the past year we have worked with MGM to convert the heating systems in several houses/buildings on our farm to more efficient and convenient systems. From the beginning Mike was very down to earth, knowledgeable and willing to listen to our needs and work with us to come up with cost effective solutions. The entire MGM team was very courteous and responsive. We are very pleased with their work.

We built our home in the summer of 2016 and decided to call Mike Messimer (MGM Mechanical) for our heating/cooling system. He installed a Bryant heat pump and we are so pleased with it. The Bryant heat pump is very cost efficient. Mike was very honest on the quote and his installation work was like no other. Mike is professional and it is very nice that he cleans up his mess after his work is completed. We know that Mike is only a phone call or text away if we need maintenance or filters. We have recommended Mike to many friends and family because of his honesty and excellent quality of work.

It is with much enthusiasm that we are recommending Mike Messimer of MGM Mechanical for all your heating and cooling needs. MGM Mechanical has been taking care of the heating system at Messiah Lutheran Church for over three years and we have been completely satisfied with the quality of the work. We have an old system whose parts are sometimes no longer available and so the heating system requires a lot of ingenuity and creativity to keep heat in our large multi-zoned church.

MGM is competitively-priced and always follows up with very prompt phone calls, texts or emails. The invoices spell out specifically what work was done and how much the labor and parts cost which is important with our limited budget. We are happy to recommend the services of MGM. Check out their website which is also excellent and spells out specifically the company's range of skills.

Mike Messimer is an outstanding service technician and I have always been amazed by his dedication, quality of work, and attention to detail with his customers. I have personally used Mike for various heating, cooling and plumbing projects over the past five years and recommend his professional ability as "Second to None".

My husband and I would highly recommend Mike Messimer for the work that was done for us. We recently had 2 Mitsubishi mini splits installed in our home for heating and cooling. No more noisy window air conditioners! The heating element can be used alone, but for us it is used as a backup for our wood stove and the air conditioning makes our air cool and clean.

We absolutely love these units and it was one of the best investments we've ever made. Mike's work is professional and is neat and tidy. He is honest and will not try to sell you something you don't need. His reputation carries him from job to job. My children call on him to do their HVAC work as well. Thanks Mike for a super job!

Mike Messimer installed a five-unit HVAC system at Landis House, the Perry County Council of the Arts' historic 5,000-square-foot mansion in Newport, in 2014. We were previously unable to run programs in our "Creative Commons" in the summertime because temperatures frequently hit the 90s inside. Because of the HVAC and new insulation, Landis House is now a four-season facility, and we heat or cool the house all year long for less money than we spent for heat alone before our reconstruction project.

Mike hit his quote numbers. He responds promptly when I phone him. If stuff needs to be attended to he gets to it right away. I am a fan.

Trust is a big word ...

Mike Messimer has earned our trust recommending, sizing and installing high-efficiency HVAC wall units, repairing and servicing our Geothermal System and installing a beautiful and mighty propane fireplace we ordered from Vermont Castings. The fireplace arrived with many design flaws which Mike tirelessly persisted in solving. He's a professional that is there when you need him, stands by his work and follows fair business practices. In our experience, Mike is one of the best!
