"I was very happy with my experience using this company. In the middle of a heat wave, right before the July 4th holiday, my AC stopped working. The man who installed it and had been servicing it was too busy to come for a week. I called MSD and was given an appointment for 8 AM the next morning. They were prompt and courteous, fixed my problem, and were reasonably priced. I will be calling them in the future."

He went through the whole install and reviewed with us on the operation of the system. We need more like him especially with the work ethic he displayed. .....accolades also go to his helper......truly an asset to his company....thank you"
