Was looking for a company to clean and check my furnace for the upcoming winter. I read a review and decided to give MG Mechanical a try. I've never been happier with the service they provided. From the friendly Melanie who set up my appointment to the friendly and professional technician Omar who was very punctual and knowledgeable. The job was completed in an hour and Omar assured me that I had many years left from this furnace. I would highly recommend this company to anyone looking for a fairly priced and professional job well done.

Just moved into our new home and after 7 days, our AC quit working. After my husband had called a few HVAC companies in the Woodstock area and seeing his frustration level rising, I decided to try. I reviewed MG Mechanical ratings and like what I saw. I called and Melanie (the person who takes the service calls and handles scheduling) was super amazing and very professional!

Unlike everyone else who told us that we would have to wait hours or days, Melanie had someone at my home within one hour. The tech that came out was equally amazing, professional and efficient. He had our AC fixed in mins and ensured that the system would continue to run well. The cost was very reasonable, as well. I would definitely recommend the company to anyone needing HVAC services.

Our business has gone to MG Mechanical for numerous contracting projects over the years and they have never disappointed or failed to meet a deadline. Great company to do work with.

They exhibited nothing by the highest level of professionalism from start to finish. The technicians showed up right as scheduled, and got the work done quickly. The whole process was really efficient and convenient.

They took care of the problem with our heat and noticed leaks in our pipes. They got one of their plumbers to come and take care of it. Both guys were polite and got the job done right
