In Union, NJ, I completed an oil to gas conversion for a residential heating system. I removed the old oil-fired boiler and installed a high-efficiency gas furnace, ensuring proper venting and gas line connections. I tested the new gas burner for optimal combustion and calibrated the thermostat for accurate temperature control. The conversion improves energy efficiency and lowers heating costs, providing the homeowner with a reliable and cleaner heating solution. The new gas system is now fully operational and ready for the colder months.
