Turning on Your Heater in the Winter

During this time of year, a few things are inevitable: leaves changing color, shorter days and colder temperatures. As the mercury drops on the thermometer, people are switching off the air conditioner and cranking up the heater. Here are a few things your business should keep in mind when turning on its heater this season:

  • Do not wait until it is freezing out to rev up your heater. Many companies discover that their heater is out of commission after the cold weather has already arrived.
  • Check your filter before starting your heater. Clean filters help your heater operate at its peak efficiency.
  • Once turned on, does your heater:
    • Emit a burning smell?
    • Sound like it is struggling?
    • Vibrate at the ducts and walls?
    • Show a carbon monoxide reading above 30?
    All of these are signs of a potentially hazardous condition. Turn the system off immediately and have it checked by a North American Technician Excellence (NATE) certified heating technician.
  • If your heater is 15 years or older, consider replacing it. An old system, even in good condition, may use only 60 percent of its available heat to warm the building.
  • Have your system professionally inspected and tuned up annually. A properly maintained heater works more efficiently and reduces your energy usage.
Prevent expensive repairs and downtime by taking care of your heating system, so your business is not left out in the cold.
