Expert Oil Furnace and Boiler Repairs - Ready to Help When You Need it Most Your oil furnace or boiler breaking down was likely the last thing you wanted to have happen. But look on the bright side – Parker Pearce Service Experts Heating & Air Conditioning technicians in Gaithersburg are just down the road, and we’re here for you all day, every day, all year round. Talk about convenience. Oil and boiler repairs slightly differ from electric or gas furnace repairs because their problems commonly are not mechanical. We’ll ask – and test – lots of questions before determining and diagnosing the problem. With oil furnace repairs, we first check to see whether the unit is firing. After that, we’ll 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. Parker Pearce Service Experts in Gaithersburg can fix all boiler and furnace repair needs. Plus, we’re available 24/7/365, so one of our professional technicians will be able to be on their way to your home soon after we process your call.
