Your HVAC system is tasked with the demanding job of keeping your residence comfortable. But when air filters are dirty, everything is affected (your air, your comfort, and your energy bill). Ignoring the signs could lead to bigger problems and costs. Let’s discuss the five effects of a dirty air filter on your HVAC system and why it’s a non-negotiable preventative measure.
1. Poor Indoor Air Quality
The immediate impact on your HVAC system due to a dirty air filter is inadequate air quality. When the air quality is poor, dust, allergens, pet dander, and pollutants can all become trapped inside your house rather than filtered out. If anyone in your household has allergy or asthma concerns, this becomes a bigger concern.
Some of the dirty AC filter symptoms include coughing, sneezing, and more general indoor allergy-triggered attacks. A clean AC filter is another big step to avoid indoor pollution and to keep the air fresh to breathe.
2. Reduced System Efficiency
A clogged air filter doesn’t allow air to flow freely. Your HVAC system is forced to work harder to push air through, which affects efficiency and increases energy costs. This results in common symptoms of a dirty HVAC filter, like less even cooling or heating.
If you’ve noticed that energy bills are increasing and you are less comfortable, often the filter is the biggest potential issue. Cleaning your AC and replacing filters on a regular basis will help keep your HVAC system efficiency at its maximum.
3. Overheating and Short Cycling
A clogged filter can lead to excessive heat in your HVAC system. If airflow is restricted, particular components, like the blower fan and the heat exchanger, need to work much harder than they should. This may result in short cycling or operation on/off at a more frequent cycle than required.
Will a dirty filter make the furnace shut off? Yes, many modern systems have a safety feature that will cause the furnace to shut down if there is too much restriction in airflow. It will only prevent damage to the system but does leave you with no heat when you need it.
4. Higher Repair Costs
As time passes and the air filter is neglected, it causes stress on the major components of the HVAC system. The blowers, coils, and compressors begin to wear more quickly. A simple maintenance issue can turn into an expensive repair.
Replacing the filters and regularly changing them is one of the cheapest ways to prevent expensive service calls. If you see that the system encounters issues frequently, check the air filter before calling a technician.
5. Shorter HVAC Lifespan
Running your system with a dirty filter reduces the service life of the heater and air-conditioner. If the unit is always working hard for the same comfort level, the mechanical components wear quicker than when it runs feed and sleep, consequently shortening the service life. You may replace your HVAC unit years earlier than you planned, all because of a 10-dollar filter.
