"Very good. Well spoken, professional, went up and beyond to make sure we were satisfied and the ac unit was working properly. Thank you for your amazing work"

"Kevin responded to my call right away about fixing my central AC. He came that same day and was able to secure and install a new component of the AC and now it s working beautifully! Would definitely recommend."

"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."

"Joe and his team were outstanding! From the moment I met Joe he was friendly, knowledgeable and made sure to answer all of my questions. He sized up the project and explained in simple terms how the process would work: The price was excellent for a new whole house Ductless Mini Split AC System . When they showed up for the install they walked through how it would be done and explained it in simple terms. They were all neat and clean as the did the job and wore their masks the entire time over the two day job. I highly recommend Joe and his team and will absolutely use them again for all of my HVAC needs."

"The assigned technician, John, was on-time, knowledgeable, provided suggestions, and thorough. Oftentimes, people don’t realize how important this service is. If I were you, I would book AC Air Duct cleaning!"

"Eric is very responsive when you call... Eric and his crew came on time and replaced our Central Air Conditioning System. We had one issue and they came back immediately and took care of it. Eric has great customer service and did a professional job. We would recommend him highly."

"Chris was very professional and did a great job with the split unit"

"Excellent.
Very professional and honest business.
Howard cleaned 2 separate air conditioning zones and also the dryer vent.
He returned about a month later when we had an unrelated air conditioning issue and helped us out at no charge.
Would very highly recommend.

"Jonathan Moya is the owner of the company. My wife and i decided to finish our basement as an extended living space. We asked for three estimates for ac and heating, and mini split systems were recommended. Jonathan Moya and comfort duct systems, was the only company that explained the deficiencies in such a system as compared to central ac and heating. He explained the pros and cons of each system- In fact, the mini split would have cost us more money! My overall experience has been nothing but positive. I found Jonathan to be honest, knowledgeable, and extremely proficient and reasonable. I was confident from the moment that I met him, and after he completed the installation of my central AC unit for a 2000 square foot basement, it confirmed my initial instincts- Jonathan is simply the best at what he does. Please believe me, because I have worked with countless HVAC so called professionals over the years, and not one of them has impressed me the way Jonathan and his company has- I will never hire another HVAC company again- these are the guys you want in your home. I give Jonathan Moya and his crew my highest recommendation. You will not be disappointed! Sam M. From Oyster Bay , NY"

"Vinny and his son are top notch. Punctual, honest, dependable, and most importantly they do a good job. They stand behind the product and their work and supports you for the long term. They have never not answered a phone call or text. Vinny has installed multiple mini splits at our house, comes yearly for the service, and has fixed our boiler. I would highly recommend them to anyone."
