"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."

"I was very happy with my service call today! The repairman, Scott, was knowledgeable and pleasant and wore a mask and gloves throughout., so I felt safe, despite the pandemic. He serviced both of my central air systems and diagnosed the problem with the malfunctioning one and fixed it. By the time he left my house was already a much more pleasant place to be!"

"Fast responsive to my inquiry. Came to see job. Quote came quick and was one of the best out of 5. I immediately admired the professionialism of everyone in the company who I spoke with. I agreed to go ahead. The two workers were very prompt and polite at all times. This job took an entire day. They rang my doorbell to let me know they were going for a replacement part so that I didn't think they weren't going to finish. They returned and finished the job. Very likeable, professional young many dealt with me and the payment. He could not have been nicer or more businesslike. Having been a small business owner for forty-five years, I know a great employee when I meet one. This company was very well represented by this young man. They did a fantastic job leaving my tennis court bright and clean and the brick patio spotless. I would highly recommend them for any kind of cleaning job that they offer. A+ business, a true pleasure! L. Curtis, Remsenburg"

Joe was on top of everything from contacting me when he couldnt make the original installation date, to following up and waiting on me to have the electrical upgrade, was on time and punctual both days its took to do the work and made sure he explained everything and I had a clear understanding of everything. I would definately recommend and hire again for any Hvac needs"

"Repairman, Andrew, came and located the problem. The ignitor had burned out, so the burners would not light. Andrew did not have the part in his truck but was able to fit in a used part from another furnace to give me heat until he got the other part. I got a call the next day and scheduled a time to put in the exact part. Again, repairman was within the stated time window. Heat working well."

"A crew of two spent a long day completely gutting my old system and installing a new state of the art system. The plumbing is extremely neat and professionally done. When the job was completed, the owner, Dennis, arrived to personally inspect the job, start the system, and make any final adjustments. The crew was professional, neat, and knowledgeable. I would recommend North Shore to anyone looking to have their heating system replaced."
