Like all the heating and cooling components in your Cleveland home, your furnace needs regular maintenance and annual checkups performed by certified HVAC technicians. Here are some things that a professional heating maintenance technician can do to make sure your furnace is functioning safely.
One of the main concerns with any type of furnace is the potential for carbon monoxide gas leaks, which can be fatal if not detected. The heat exchanger is designed to prevent dangerous flue products from leaking into the home; therefore, it is important to inspect the heat exchanger for any cracks or excessive corrosion.
There are a few methods for introspecting a furnace heat exchanger for leaks and potential repairs (again, best performed by a professional HVAC technician):
- Visual Inspection of the Furnace Heat Exchanger. Use a strong flashlight to visually check the heat exchanger thoroughly for cracks or open seams, particularly in areas that are susceptible heat or mechanical stress. Some seams may have been joined improperly during manufacturing, so be sure to check all joints. Also check for rust or corrosion in areas exposed to any type of moisture. Make sure you can gain access to all the parts of the heat exchanger. If you see any cracks, holes, or severe deterioration, your heat exchanger needs a professional repair. Ultimately, you may not be able to see all the parts of your heat exchanger, so further testing is recommended in addition to a visual inspection.
- Flame Test. You can also observe the flame after the furnace is first turned on to detect potential damage to the heat exchanger. Turn off the furnace for at least five minutes, and sit close enough to the furnace to observe the burner flame. Have someone turn up the thermostat, and watch the flame for any changes in color or irregular patterns in the flame. If the flame makes any sudden changes, this could mean that the heat exchanger is damaged. Keep in mind that like the visual test, the flame test cannot determine damage to your heat exchanger alone.
In addition to increasing efficiency and lowering your heating bills, inspecting your furnace will ensure that your heating system operates safely throughout the winter. Along with having your heat exchanger inspected, we recommend that you test all the carbon monoxide detectors in your Cleveland home on a regular basis, as well as changing the filter every month and cleaning out the ventilation system.
If you need further assistance, or suspect any leaks in your furnace, you will need to schedule an appointment with a Cleveland HVAC technician. Keep your home warm and safe this winter.
