When it’s cold out and the furnace quits working, there’s little comfort in knowing that most failures are preventable. As temperatures drop, it is wise to hire a Heating Company in Palatine to give the furnace a pre-season inspection. While furnaces are composed of multiple systems and parts, the five most common failure reasons are listed below.
Clogged or Dirty Air Filters
The filter inside the furnace is intended to keep particulates such as dust and pollen from being blown throughout the home. However, many do not realize that air filters are also made to ensure the furnace’s efficient operation. Furnaces can become unusable when the filter gets dirty enough to block airflow. To prevent such problems, customers should regularly check the filter and replace it when necessary.
A Malfunctioning Thermostat
While technically not a reason for furnace failure, the unit may not work if the thermostat doesn’t function properly. A heating company like Five Star Heating & Air Inc will test the thermostat before evaluating the furnace for signs of damage.
Pilot Lights
A furnace may have an electronic ignition or pilot light, depending on its age. If the system fails, a gas-fueled furnace won’t light the burners and heat won’t be made. A yearly or biyearly inspection can reduce or eliminate the chances of ignition system failure.
Blower Motor Failure
If the fan or blower motor has stopped working on a furnace, no air will move throughout the home. The furnace may activate and engage, but a non-working blower motor means that air will not be circulated. The fan motor is a part of the furnace’s circulatory system, and an HVAC tech will inspect the belts, motor, and bearings before replacing worn components.
Fuel Supply Issues
Furnaces are fueled by natural gas or electricity, and any problems with the power source can prevent the furnace’s proper operation. However, due to the dangers associated with gas and electricity, homeowners should hire a Heating Company in Palatine to do the repairs.
Proper and frequent maintenance, as well as prompt attention to the issues listed here, can reduce the number of failures a furnace experiences over its lifespan. Additionally, regular maintenance can ensure the unit’s continued efficient operation.
