"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!"

"Justin was recommended to me by my neighbor. He was polite on time, extremely knowledgeable, and did a great job servicing my washer/dryer, refrigerator and oven. Now I know why my dryer (Bosch) has to work so hard (stupid NYC restrictions on amperage) and why my oven doesn't cook the way it should (again European appliance in NYC). I would recommend Justin to anyone. In fact, I posted my review on my building's electronic bulletin board and my neighbors are calling him and raving about his service!!!"

"Worked with Joe from Sales to determine what type of A/C I needed, he was very helpful throughout the entire process and was patient with all the questions I had. Installation went smoothly, I was already doing house renovations so half my walls were already open so everyone knew what they were getting into. I like the fact there was a customer service rep who contacted me afterwards and said she would be my point of contact for any issues. I already asked her some clarification questions and she is responsive."
