When you have a furnace in your home, you expect it to work well and keep you warm all winter long. However, even the best of furnaces can have problems from time to time.
If you are worried that your furnace may be having some issues, look at this list of common furnace problems to see if any of them sound familiar.
The Furnace Is Making Strange Noises
If you hear strange sounds coming from your furnace, it could be a sign that something is wrong with the motor or that some other part of the furnace is wearing out. If your furnace is making unusual noises, it may be time to call in an expert to handle any furnace repair.
The Furnace Is Not Heating the House Properly
If your furnace is not heating your house correctly, it may be time for repair. Some things could be causing this problem, including a dirty filter or a broken part.
The Furnace Keeps Shutting Off
If your furnace is constantly shutting off, it may be a sign that there is something wrong with the thermostat or that the furnace is overworked. If your furnace keeps shutting off, you should call in an expert from Air Makers to find out what is wrong and fix it.
The Furnace Is Smoking
If your furnace starts smoking, it could be a sign of trouble. You should call in an expert immediately to avoid any serious furnace problems.
How to troubleshoot a furnace problem?
There are different furnace problems, as illustrated above. Below are some of the ways to troubleshoot your furnace:
Furnace problem: Blown fuse or tripped breaker
If your furnace is not working and the appliance is plugged into a receptacle, make sure there isn’t a blown a fuse or tripped circuit breaker in the house panel box. The tripped circuit breaker could be located in another section of your home other than where it’s installed.
If your furnace is not working and it’s unplugged, check the main electrical panel in the home to ensure that no circuit breakers in any section of your home have been tripped off. If a circuit breaker in another housing area is tripped, switch it back on and start with an alternate part of the circuit breaker box.
If you have checked both the fuse and circuit breaker box, they are fine, and then there may be a problem with your furnace.
Furnace problem: The pilot light is out
If your furnace has a pilot light, it’s essential to make sure it is lit. If the pilot light is out, you’ll need to relight it.
If your home doesn’t have a pilot light, then you’ll need to locate the furnace’s manual reset button and press it in to reset the switch. If no one has done this recently, there may be an issue with your furnace.
Furnace problem: The system is not working
If your furnace is not working, it’s essential to determine whether the system is blowing cold air or no air at all. If the system is blowing cold air, you may have a problem with the thermostat setting or the filter.
If the system is not blowing any air, you may have a problem with the blower, the motor, or the limit switch.
Furnace problem: Rattling noise
If your furnace is making a rattling noise, it’s crucial to determine where the noise is coming from. The rattling could be caused by a loose panel, a dirty filter, or a broken belt.
Furnace problem: The furnace is cycling on and off too frequently
If your furnace is cycling on and off too frequently, it’s crucial to determine the underlying cause. The problem could be a dirty filter, a blocked airflow, or a problem with the thermostat.
Furnace problem: The furnace is not heating properly
If the heating system is not working correctly, first check to make sure there’s a power supply running to it. If your furnace has a pilot light, make sure it’s lit.
If you have checked both the fuse and circuit breaker box, and they are fine, then you may have an issue with your furnace.
Furnace problem: The furnace is working but is not producing enough heat
If your heater is working correctly, but it’s not producing enough heat, you probably have a heat exchanger or single-speed blower problem. You may have to call a professional to fix this issue.
Furnace problem: The furnace is running too loudly
If your furnace appears to be running too loudly, you can first try to resolve the issue by checking for dirt around its blower and cycling system. If this doesn’t work, check the capacitor and limit switch.
How to take care of a furnace
Keep the furnace area clear
It is vital to keep the area around your furnace clear to have plenty of airflow. If the area around the furnace is cluttered, it can cause the furnace to work harder than necessary and may lead to problems down the road.
Change the filter regularly
One of the best ways to keep your furnace running smoothly is to change the filter regularly. A dirty filter can cause the furnace to work harder than necessary and lead to many problems.
Inspect the furnace every year
It is crucial to inspect your furnace every year to ensure no problems with it. If you find any issues, you should call an expert to fix them.
Get annual maintenance done
It is also a good idea to get yearly maintenance done on your furnace to help keep it running smoothly. It will help to catch any problems before they become too serious.
Make sure it is the right size for your house
It is also a good idea to make sure that your furnace is the right size for your house. You don’t want to get a furnace that isn’t big enough to heat your home, but you also don’t want a too big furnace for your house because it will work harder than it should to keep your home warm.
In a nutshell, if you are experiencing any of these common furnace problems, be sure to call in an expert to handle the repair. It is essential to fix any furnace problems as soon as possible to work well for years to come.
