 Both of these systems and the others they have, many of them come with rebates and federal tax credits up to $10,000. And keep in mind, some of them cool and they heat and they're very efficient, start to pay for themselves right away. But you call them. You call them at 401-461-8100, make an appointment, get a free in-home estimate, and they'll come out and tell you exactly what you need. And right now with the sale going on, plus the rebates, do it.
