Professional Oil Furnace  Maintenance & Repair

Oil furnaces are known for their durability, powerful heat output, and ability to perform well in colder climates like those in Western North Carolina. While these systems can last for many years, they require more frequent attention than gas units due to the nature of heating oil combustion. Without regular maintenance, oil furnaces can become inefficient, dirty, and potentially hazardous.


At Legacy Heating & Air, we specialize in comprehensive oil furnace service and furnace repairs to keep your system running safely and efficiently. Our team is trained to maintain and repair all components of your oil heating system, ensuring dependable heat throughout the winter months.

  • Adjusting flame settings for efficiency

    Calibrating the flame to burn cleanly and efficiently, which helps reduce fuel waste and emissions.

  • Checking and replacing blower motors

    Inspecting moving parts that circulate warm air, ensuring they’re in good working condition or replacing them if needed.

FAQs – Gas & Oil Furnace Services in Western NC

  • Q: How often should I service my gas or oil furnace?

    A: We recommend scheduling a tune-up once per year, ideally in the fall before heavy use begins. Annual maintenance keeps your system efficient, reduces the risk of breakdowns, and ensures safe operation.

  • Q: What’s the difference between gas and oil furnaces?

    A: Gas furnaces typically use natural gas or propane and tend to burn cleaner and more efficiently. Oil furnaces use heating oil and often provide stronger heat output but require more frequent cleaning and filter changes. We service both systems and can help you understand what works best for your home.

  • Q: Can you convert an oil furnace to gas?

    A: Yes, in some cases. Converting from oil to gas depends on fuel availability in your area, ductwork, venting needs, and system compatibility. We’ll assess your home and help you explore your options if you’re considering a conversion.

  • Q: What should I do if I smell gas or oil near my furnace?

    A: Turn off the system, ventilate the area if possible, and contact us immediately. Fuel smells may indicate a leak or malfunction, and it’s important to have a professional technician inspect the system for safety.
