Just about any electrical appliance has the potential to overheat, and furnaces are no exception. As a Leander homeowner, you need to take precautions to lower the risk of an overheated unit. You should also be wary of the associated symptoms so you know when to take action.
Remember, if your system gets too hot, you should keep a cool head and get your furnace taken care of right away.
We want to keep our customers in the know about overheating furnaces. Our team here at MLD Services compiled the following information for you.
The main way to keep your furnace from overheating is ensuring correct airflow. Hindered airflow causes the system’s components to work abnormally hard, causing them to overheat.
Here’s how to keep your appliance in check:
Not every filter is created equal. Some filters create a resistance your system isn’t designed to handle. Be sure to read the manufacturer’s recommendations on correct filters, and consult a heating, ventilation, and air conditioning (HVAC) expert if you’re still not sure.
If you let the dust settle for too long, your filter can become clogged. This clog significantly compromises airflow, which causes the machine’s parts to overwork and eventually fail. Check the manufacturer’s manual to see how frequently you need to change your filter. We, as well as ENERGY STAR®, recommend inspecting your filter every month.
• Be sure your vents/ducts aren’t blocked.
Blockages in your vents are hard on your furnace, causing the equipment to run too long. Be sure to clear away any obstructions near and/or on them, including carpets, furniture, and curtains. Additionally, keep your ducts clean and free of any leaks or constrictions.
• Have a technician perform routine maintenance.
How Do I Prevent My Furnace From Overheating?
Regular maintenance, annually or semiannually, is a necessary step in protecting the condition of your system. One of our MLD Services technicians will clean any dirty coils, fasten loose components, and be sure the system is performing optimally in your Leander home. This will significantly lower the risk of a malfunction.

This is the most common sign of overheating. It actually shuts down to protect you. When your heat exchanger gets to an unsafe temperature, the high-limit switch detects this and automatically turns the furnace off.
