ComfortSystems cares about our community and our environment

That's why we're dedicated to educating and informing our customers about simple ways to become more energy efficient! How can we help you? Aside from informing you about fuels and energy saving ideas, we offer some programs that help you better understand your fuel usage.

Carbon Dioxide (CO2) emissions and other heat trapping gasses are changing the composition of the earth's atmosphere. We call these emissions "greenhouse gasses," and the amount generated by your household depends on your home's type of energy use and demand.


The Fuels you use to power your home make a difference.

Fuel sources ranked from cleanest to dirtiest in terms of air emissions:

  • Renewable fuels such as wind and solar
  • Natural Gas
  • Oil
  • Coal

Natural Gas is the cleanest fossil fuel, emitting 40% less C02 per unit than oil. It also emits less Sulfur Dioxide and Nitrogen Oxides than oil or coal.
