As the backbone of your home’s heating system, your furnace works endlessly to keep you warm during the colder months. However, like any mechanical system, it can be prone to issues, one of which is overheating. An overheating furnace not only compromises the comfort of your home but can also pose serious safety risks. Today, Hal Mechanical would like to cover some of the common causes of furnace overheating and how to prevent them.
Restricted Airflow
One of the primary causes of furnace overheating is restricted airflow. When the hot air generated by the furnace can’t circulate properly, it can cause the system to overheat. To improve your furnace’s airflow you should:
• Change Dirty or Clogged Filters: Regularly replacing or cleaning furnace filters is crucial. Clogged filters block the flow of air, causing the furnace to work harder and potentially overheat.
• Blocked Air Vents: Furniture or other objects blocking the air vents in your home can also contribute to overheating. Ensure all vents are clear and open.
Mechanical Furnace Failures
There are a number of mechanical issues within the furnace that can lead to overheating. A licensed HVAC technician will often check:
• Blower Motor Problems: If the blower motor is faulty or fails, it can’t circulate air through the furnace, leading to overheating.
• Wear and Tear on Components: Over time, regular wear and tear can affect the furnace’s ability to operate efficiently, potentially causing it to overheat.
Issues with the Thermostat
Sometimes the problem isn’t with the furnace itself but with the thermostat. Before calling a HVAC service you should check:
• Incorrect Thermostat Settings: If the thermostat is malfunctioning or set incorrectly, it can cause the furnace to run longer than necessary, increasing the risk of overheating.
• Thermostat Calibration: An improperly calibrated thermostat can misread the actual temperature, leading to continuous furnace operation.
Poor Furnace Maintenance
Regular maintenance is vital for the efficient and safe operation of your furnace. To Ensure your furnace stays healthy the following is recommended:
• Annual Servicing: Skipping annual maintenance can lead to a buildup of dust and dirt, as well as wear on components, all of which can contribute to overheating. You will want to have your furnace tuned-up once a year. The best time is before the major heating season.
Faulty Furnace Installation
Improper installation of the furnace or ductwork can cause operational problems, including overheating. One of the most common problem is:
• Incorrect Size: A furnace that’s too large for your home can cycle on and off too frequently, while one that’s too small may overwork to heat your space, both leading to overheating. It is essential to have the proper size furnace for your home.
