"Decided to give MSD a call as I had another company over the house today to fix my AC and they were not able to repair it as they needed to order parts. Mehmet answered the phone and couldn't have been more professional/helpful. He spent 10 or so mins on the phone with me trying to understand the problem and give me advice. He unfortunately couldn't send some one out as he was super jammed with the current heat wave. I will not hesitate to call Mehmet again as he is a true professional and very knowledgeable."

"We had a phone call and he actually helped me figure out that I might need a plumber instead of HVAC repair. Mark was very courteous and so helpful! If we do end up needing to go back to him I will definitely call for them to make a visit."

"This Company is top notch! They quickly responded to my urgent message in regard to no heat in the house and had the service guy arrive to the door right after completing another job. They were very professional and did the repair in no time and price quoted over the phone was exactly what was charged for the service. We will definitely call this Company again for any boiler repairs. Thank you!"

"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!"

"Kahlil is very professional, takes his time to answer questions, arrived at appointed time even during a rain storm. During the course of the install, it was found wiring for the air conditioning needed to be changed from 110 to 220. Khalif found someone to take care of it immediately. The men working with him -Andy and Jose, were courteous, left the work site in a neat and clean order- they placed protective coverings down to protect my wood floors. We are now enjoying a comfortable evening in our home . I highly recommend Khalifa and his company"

"Installed a free standing Viking 5 series. (Not in options) Justin was great!. Efficient, knowledgeable, prepared (had "maybe" parts at the ready) and best of all a warm personality. He made adjustments to the stove and pointed out manufacturing/shipping problems that I would not have seen, and gave me advice on getting them sorted. I would recommend him to anyone who needs this type of service."
