We may recommend a larger main line or a meter upgrade from your gas utility. A properly sized line lets the heater reach its rated output and heat the water efficiently.

Yes, we can install the gas line needed to switch from an electric appliance, such as a water heater or clothes dryer, to a gas-powered one. This usually involves extending an existing gas line or installing a new one, along with proper venting if needed. We ensure all connections are safe and meet appliance specifications.
We use trusted, industry-standard brands for gas line materials and fittings for durability and safety. This includes manufacturers like Gastite and OmegaFlex for CSST, and high-quality black iron pipe and fittings from reputable suppliers. All materials are selected to meet or exceed local plumbing codes.
