"We chose a WaterFurnace system because it's a top-of-the-line system. We're very happy with it. The air is always clean and fresh. And the best thing is it's worry free. I can set the thermostat on 70 and no matter if it's 20 degrees outside or 110 in the shade, I don't have to mess with this system at all. And it doesn't cost us an arm and a leg to heat and cool."
