Six Signs! It’s Time For Furnace Repair or Replacement


For effective heating to take place, the furnace must be maintained in proper working condition, which often includes basic, simple upkeep provided by the homeowner. While furnaces may be repaired when they malfunction, there are times when replacing the furnace is a more suitable option, especially if you have had it for many years.

The following are six furnace warning signs to let you know when it’s time to have your furnace assessed by a home heating expert.

 Abnormally High Heating and Gas Bills

Furnaces that are not well maintained often become inefficient, leading to increased energy consumption. Heating and gas bills will increase due to rising gas prices. Instead of paying abnormally high energy bills every month, consider if you have been taking the routine steps to keep it in top condition. Filters being changed several times during the winter is one thing that must be done, as well as checking for gas leaks.

Irregular Heating In the House

If the temperature in a room does not reflect the setting on the thermostat, or you need to adjust the device frequently, this may be an indication that the furnace is not working properly. Make sure the uneven heating isn’t due to unaddressed drafts coming from cracks and spaces in flooring, doors, or windows.

3. Strange Noises From the Furnace

Furnaces usually make strange noises as they approach the end of their life. If you hear squealing, rattling, popping or banging noises, this may be a warning sign. If the blower blows cold air at times, or it turns on and off frequently, you may need to call a professional to see if parts need to be replaced, or if the entire unit is on it’s last legs.

 Excessive Dust and Dryness in the House

An aging furnace with an attached humidifier may not be able to effectively moisturize air or get rid of dust from the circulation system. If you notice drooping plants, static shocks or frequent accumulation of dust in the house, you should take it as a warning sign. Airborne particles such as dust, pollen, dander and mold may cause allergies and respiratory infections, and if the furnace filters have been changed regularly, then it may be that the humidifier is not working.

 Yellow Flame in the Burner

The burner in an efficient furnace normally produces a blue flame. As the device nears the end of its life, it may start producing a yellow flame and soot. Also watch out for moisture on walls and windows as well as excessive rusting around pipe connections, appliance jacks or flue pipes.

 Frequent Repairs

Furnaces, like other machines, can be repaired when they break down. During repairs, faulty components may be replaced. However, when these breakdowns and repairs become too frequent, it’s a good sign that the furnace itself may need to be replaced. The frequency of furnace breakdowns normally increases in the last two years of their life.
