Everything about our dealings with Cool Power has been terrific. (We investigated three companies thoroughly before signing on.) The initial installation was done professionally and we were happy with the results - a new, efficient system, at a reasonable cost. When we had difficulty with LIPA (we were due a rebate, which somehow fell through the cracks at LIPA, but this was paperwork after Hurricane Sandy, so no surprise, really…), Cool Power stepped in and helped us expedite it. We have signed up for the annual maintenance contract for the past two years, feeling we wanted to protect our investment, and the service has been prompt, professional, and thorough both years. We recommend Cool Power to anyone who is looking for the services they provide.
