I called Cotrolling Systems and I was assisted immediately. I talked to `Dave Bell and made an appointment for a house inspection and estimate. Dave came over , checked our house made some measurements, We discussed our options and he took the time to explain the differences . He left us with some brochures and a proposal to consider, he also recommened that I checkout the Carrier Web site. I read and learned. We made a deal over the phone and the system was installed by a extremely nice,clean, professional crew.
