"Great job done. very professional. Took the unit out and fully serviced it. when they brought it back it ran like new."

"Ivan and his assistant were very well-versed in the business of installing a heavy air-conditioner in a double-hung window. Their physical strength amazed me, as they carefully carried, placed and successfully manipulated the unit into the window opening. Then, they stabilized and secured it. Finally, the “moment of truth”, Ivan turned on the unit and a flow of cool, dry air burst into my large den and I was comfortable at last! I would recommend them wholeheartedly!"

"I hired Matt when I needed a few things like installing an ac, building a few cabinets, and later on to hang some heavy items . Matt was always friendly, on time, and willing to go the extra step to make sure I was happy with how everything looked! I’ll reach out to him again next time I need help, and recommend him to others who need work done!"

"Mark and his wife were both wonderful to work with. They had great communication, arrived on time and got the job done within an hour. I am very happy with my new units and the quality of their work. Will hire again for other repairs and installations!"

"shield over basement window stop water coming in"

"Came after 4pm, which was within time frame wanted, since heat wave in effect. Worked fast, machine up and running in about 15 minutes. They took my old machine away also. After they left noticed 2 small screws omitted from sides up front. Couldn't put them in myself, but left it alone since it didn't affect anything. Used silicone sealant around machine as final seal. Wish they gave more info on caring for machine down the road, otherwise service was good, and kept work area clean. Although expensive, will use them again if needed.. Purchased new machine with delivery and install."
