"We did the absolute right thing by going with WaterFurnace and TEC. It costs much less than heating and cooling with gas or oil. And it's the most environmentally friendly system there is, which is a big concern to us. We don't like burning fossil fuels so it was the only sensible choice. When we were building our home, we knew it would be our retirement home, so we wanted the most economical and environmentally responsible system available. I had read an article about geothermal and started doing more research on it. WaterFurnace has the most reputable brand on the market. The air is always warm, and the air conditioning feels naturally cool. It's definitely worth the investment. I especially love the fact that the system doesn't require upkeep, just clean your filters. No expensive servicing of the furnace every year and no worry about harmful fumes or emissions. We're the poster children for geothermal technology. We love it!"
