It's the time of year when your furnace is working overtime to keep your home warm. You want to make sure that it is running as efficiently as possible, so you should check your air filter routinely and replace it when it gets dirty. A dirty air filter can cause several common furnace problems, including health and safety hazards. In this article, we will discuss the four common furnace issues caused by dirty air filters.
1. Furnace Overheating
If your furnace is overheating, it could be caused by a dirty air filter. The first thing you should do when this happens is to check your home's temperature. If the temperature has dropped below 65 degrees Fahrenheit, there may be an issue with the thermostat or heating element that needs immediate attention since both are safety hazards.
If the temperature is normal, but your furnace continues to overheat, then a professional for the HVAC unit in Atlanta should check to see if it needs to be replaced. A dirty air filter will impede airflow, causing the furnace to work harder than necessary and overheat.
2. Damaged Blower Motor
A dirty air filter can also damage the blower motor. The blower motor is responsible for moving heated and cooled air throughout your home, so if it becomes damaged, you will not be able to heat or cool your home properly. The best way to prevent this from happening is by replacing your air filter when it gets dirty.
3. Poor Air Quality
If you notice that your home does not feel as warm or cool as it normally does, or if you are experiencing allergies or other respiratory problems, it may be because of the air quality. By trapping dirt, dust, and other particles inside the furnace, a dirty air filter can lead to poor air quality.
Along with air filters, it is also important to know what happens when you don’t change the AC filter since both use the same principles.
4. Cracked Heat Exchanger
A dirty air filter can also result in your heat exchanger cracking. The heat exchanger is responsible for heating the air that passes through it and then sending this hot air into your home. If there are cracks in the heat exchanger, carbon monoxide can start leaking out of them into the room where you have your furnace installed.
These were just a few of the common furnace problems that can be caused by a dirty air filter. It's also always best to get it checked and serviced by a professional technician as they will also be able to tell you if any other issues need to be addressed.
