"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!"

"I hired Triple R and they did a great job installing the multi zone mini split AC units. I would highly recommend them, very affordable and great service"

"I had a great experience with my recent AC installation experience. He took his time ensuring the unit was completely secure and sturdy in place. Before packing up his tools, he made sure the AC was working well and that I was satisfied with everything. I cannot recommend him enough."

"Excellent work. Have a wonderful door Paul installed it terrifically I would definitely use them again."

"They came when they said they would, evaluated my existing/dying AC unit accurately - not worth repairing - and helped me take it out of the window. Their bill was modest and their personnel very pleasant."
