I had used a company that shall remain nameless to install my last set of ductless mini-splits, but working with ProTech was a far better experience. Steve and the technicians were on time for every appointment, from the estimate to the actual work, which was carried out neatly and efficiently. I had been somewhat hesitant to go with the Carrier line, but the system turns out to be much better than the Daikins that the last company had installed. ProTech, I'm your fan!
