Oil and boiler repairs are a little different from electric or gas furnace repairs because their problems aren’t usually mechanical. We’ll ask – and test – many questions before determining and fixing the problem. With oil furnace repairs, we first check to see whether the unit is firing. Next, we move on to checking the fuel supply. Because boilers heat using water, we’ll see if the problem is water-based or machine-based and proceed from there. Golden Seal Service Experts in Saint Charles can fix all boiler and furnace repair needs. Plus, we’re on call 24/7/365, so one of our experts will be able to come out to help you ASAP after we process your call.
