Go GreenEnergy efficient systems save you money

If your HVAC system is more than 7 years old it’s time for a change! Over the past 7 years, HVAC equipment has doubled in efficiency. The utility savings alone will pay for a new unit in a short time. Replacing components of a less efficient HVAC system typically cuts energy costs by about 20 percent (EPA). “Going Green” doesn’t mandate that you become an environmentalist, it simply means that you use common sense by utilizing more efficient technology.
