As the temperatures drop, a well-functioning furnace is essential to keeping your home warm and comfortable. However, like any mechanical system, furnaces can sometimes encounter problems. Before calling in a professional, there are several common issues you can troubleshoot on your own.
Here are 10 common furnace problems and furnace troubleshooting to help you get your heating system back up and running.
Problem: The most obvious sign of furnace trouble is when it simply won’t turn on.
Solution: First, check your thermostat to ensure it’s set to “heat” and that the temperature is higher than the current room temperature. If that’s correct, inspect the furnace’s circuit breaker or fuse box to see if it has tripped. Reset the breaker or replace the fuse if necessary. If the issue persists, check if the furnace’s pilot light is out or if the air filter is clogged.
Problem: If your furnace is running but blowing cold air, it may not be heating properly.
Solution: Start by checking your thermostat settings to ensure it’s set to the correct mode. If that’s not the issue, the pilot light might be out, or the gas supply may be disconnected. Additionally, a dirty or clogged air filter can restrict airflow and cause the furnace to overheat, shutting down the burner but leaving the fan running.
Problem: If your furnace keeps turning on and off, it’s likely “short cycling,” which can lead to higher energy bills and inefficient heating.
Solution: A common cause of short cycling is a clogged air filter. Replacing the air filter often resolves the issue. Another potential cause could be a malfunctioning thermostat, so double-check the settings and replace the batteries if needed. If neither of these solves the problem, it could indicate an issue with the furnace’s blower motor or heat exchanger, requiring professional attention.
Problem: When the furnace is running, but the airflow is weak, your home may not heat evenly.
Solution: Check your air filter first—if it’s dirty or clogged, replace it to restore proper airflow. Also, make sure all supply and return vents are fully open and not obstructed by furniture or other objects. If weak airflow persists, there could be an issue with the blower fan, ductwork, or even the furnace’s motor.
Problem: A pilot light that won’t stay lit is a common issue with older furnaces.
Solution: The first step is to inspect the pilot light and thermocouple. If the pilot flame is flickering or weak, it may need cleaning. If the thermocouple (the sensor that controls the gas valve) is faulty or misaligned, it may need to be replaced. This is a job best left to a professional if you’re unsure of how to handle gas appliances.
Problem: Unusual noises like banging, rattling, or squeaking from your furnace could signal a problem.
Solution: These noises can indicate various issues, such as loose components, a malfunctioning blower motor, or dirty burners. Tightening loose parts and cleaning the burners may resolve the issue. However, persistent loud noises should be inspected by a professional, as they may indicate more serious problems, such as a cracked heat exchanger.
Problem: If your furnace continues to run even after reaching the desired temperature, it’s wasting energy and overheating your home.
Solution: Check the thermostat settings to ensure it’s set to “auto” rather than “on.” The “on” setting will cause the fan to run continuously. If the furnace still doesn’t shut off, the thermostat may be malfunctioning, or there could be an issue with the furnace’s limit switch, which requires professional inspection.
Problem: A clogged air filter can cause various furnace issues, from poor airflow to short cycling and inefficient heating.
Solution: Replacing the air filter is an easy fix and should be done every 1 to 3 months, depending on usage and the type of filter. Regularly changing your air filter will improve your furnace’s efficiency and prevent many common problems.
Problem: If you notice water pooling around your furnace, you may have a condensation issue.
Solution: High-efficiency furnaces generate condensation, and if the drain line or condensate pump is clogged, it can lead to leaks. Check the drain line for clogs or kinks and clean it if necessary. If the problem persists, there could be a more serious issue, such as a cracked heat exchanger, which requires professional repair.
Problem: A sudden spike in your energy bills could indicate that your furnace is not running efficiently.
Solution: The first step is to check and replace the air filter if it’s dirty. Also, ensure your home is properly sealed and insulated to prevent heat from escaping. If these steps don’t resolve the issue, it’s possible that your furnace is aging and may need a tune-up or even replacement. Regular maintenance is key to keeping your furnace running efficiently and keeping your energy costs under control.
While many furnace issues can be resolved with basic troubleshooting, some problems require the expertise of a certified HVAC technician.
