Oil to Gas Conversion Specialists
There has never been a better time to convert your heating and hot water system from oil to gas. North American production of natural gas is increasing and has provided a stable and regulated pricing structure. Today’s gas equipment is unmatched in safety, efficiency, reliability and design. Southern Connecticut Plumbing & Heating has the experience, expertise and ability to make the conversion of your heating system a timely and trouble free home improvement.
WHEN SHOULD I REPLACE MY OIL OR GAS EQUIPMENT ?
Systems installed as few as ten years ago were often designed and built with little advancement or change from the systems our grandparents owned. Today is another story! Efficiency and operational improvements are in demand and manufacturers have answered abundantly. Lower heating and hot water cost are readily available with modernized equipment.
Call Will at 203-876-7875 for your no cost heating and hot water system evaluation.
