Quite frankly don't understand how they are still in business!! So rude and disrespectful! Installers made mistakes wiring my new installation, reversed the wiring, drilled holes in walls and never used, ran bare wires across ceiling. The unit turned on when it should have been off and other way around. Ended up calling another company to fix it. Now I call for replacement user controller and he quotes an outrageous price. I question it and he yells at me and hangs up! RUN from this place"
