  • Natural gas typically costs significantly less to heat a home than heating oil. Many Connecticut homeowners save 25% or more on their annual heating bills after converting.
  • Natural gas is delivered continuously through underground pipelines. No running out mid-winter, no scheduling emergency oil deliveries — your heat simply works.
  • Natural gas produces fewer emissions than heating oil. It is a practical, lower-impact choice for Fairfield homeowners who want efficient heat and a smaller environmental footprint.

Our Process: What to Expect During Your Oil-to-Gas Conversion in Fairfield, CT

Today’s high-efficiency gas furnaces operate at 96% AFUE or higher, meaning nearly every unit of fuel you pay for becomes usable heat. Modern gas boilers offer similar performance gains.

Our conversion process includes:

  • In-home assessment to evaluate your current system and fuel access
  • Coordination with your utility provider if a new gas line is needed
  • Professional removal of your existing oil heating equipment
  • Installation of your new system, whether a gas furnace, boiler, or dual-fuel system
  • Full system testing, calibration, and inspection before we leave

Our certified technicians treat every oil-to-gas conversion as a major investment in your home.

Contact us today to get started. We take a thorough approach, work cleanly, and leave your new system ready to perform.
