7 Signs to Look Out For Before Winter Gets Here for Your Furnace


As the leaves begin to fall and the air turns crisp, the arrival of winter is just around the corner. To ensure a cozy and comfortable home during the colder months, it’s essential to prepare your furnace for the increased workload. Neglecting your furnace’s maintenance can lead to inefficient heating, higher energy bills, and even unexpected breakdowns. In this blog, we’ll discuss seven crucial signs to look out for before winter sets in, helping you ensure that your furnace is ready to keep you warm and toasty.

  1. Odd Noises: Unusual sounds coming from your furnace can be a clear indicator of underlying issues. If you hear banging, screeching, rattling, or whining noises, it’s time to have your furnace inspected. These sounds can be caused by loose or damaged components, and addressing them early can prevent more significant problems during the winter months.
  2. Reduced Heating Performance: If you’ve noticed that your home isn’t as warm as it used to be or it takes longer to reach your desired temperature, your furnace might be losing efficiency. This could be due to clogged filters, malfunctioning thermostats, or even a worn-out blower motor. Regular maintenance and cleaning can help restore your furnace’s heating performance.
  3. Increased Energy Bills: A sudden spike in your energy bills, especially during the winter, can be a sign of a struggling furnace. As your furnace becomes less efficient, it works harder to maintain the desired temperature, leading to increased energy consumption. A professional inspection can identify and rectify the root cause of this problem, potentially saving you money in the long run.
  4. Frequent Cycling: If your furnace is turning on and off frequently, it may be short-cycling, a problem that can put unnecessary strain on the system. Short-cycling can be caused by various issues, including a malfunctioning thermostat or a clogged air filter. Addressing this issue promptly can extend your furnace’s lifespan and improve its overall performance.
  5. Uneven Heating: Is one room significantly colder than the rest of the house, even when the furnace is running? This could be due to blocked vents or ductwork issues. It’s essential to ensure that warm air is evenly distributed throughout your home to maintain a comfortable living environment during winter.
  6. Strange Odors: Unpleasant odors emanating from your furnace can be a cause for concern. Musty or burning smells may indicate a problem with the furnace, such as a clogged air filter, a malfunctioning motor, or even a gas leak. If you notice any unusual odors, it’s crucial to turn off your furnace and contact a professional technician immediately.
  7. Yellow or Flickering Pilot Light: For gas furnaces, the pilot light should be a steady blue flame. If it’s yellow or flickering, it could be a sign of incomplete combustion, which can release harmful carbon monoxide into your home. The presence of carbon monoxide is extremely dangerous. If you suspect this issue, evacuate your home and call for professional assistance right away.


Your furnace is your ally in keeping your home warm and cozy during the winter months. By paying attention to these seven signs before winter arrives, you can catch potential problems early, prevent costly breakdowns, and ensure that your furnace operates at its best efficiency. Regular maintenance and professional inspections are key to a trouble-free and warm winter season, making it possible for you and your family to enjoy the season without worrying about heating issues. Stay warm and safe!
