What Goes Wrong When Your Homes Air Filter is Clogged?

So what is the importance of your air filter?

Does it really matter? Yes! Preventative maintenance can extend the life and efficiency of your HVAC unit.

When you have a clogged air filter, the air handler has to work a lot harder because the air flow has been blocked. This means that you are using more energy in your home and increasing your electric bill.

Along with making your home’s utility bill more expensive, this reduction in air flow through your home’s cooling and heating system can overheat and shut off too fast. This results in your home not cooling down.

Five Reasons to Clean Your Air Filter

Below are some of the things that can happen when you don’t regularly change your air filter and some symptoms to look for.

1. Dirty Filters Increase Energy Consumption

Since your system will rely on air constantly recirculating, the way that your system’s blower wheel is performing can greatly impact the amount of energy your home uses. When the fan is working hard to draw the air through your home, you are going to have higher energy bills.

When your air filter’s clogged, it can cause an increase in whole house energy consumption. This will increase the longer your filter is clogged and not serviced.

2. A Clog Can Cause Evaporator Coils to Freeze

When you have a clogged air filter during the summer, when you are keeping your house cool, it can cause your cooling or evaporator coil to become frozen. This happens because there isn’t enough air moving around your coil to get rid of the condensation that often is produced during cooling the air moving through the unit.

Not having adequate airflow will cause freezing of the condensation, which means your unit can’t cool down your home. It also will likely make it break down eventually. And create sheets of ice inside your air handler.

3. A Clog can Cause Inadequate Heating and Cooling

The blower fans will push air through your filter. If the filter is excessively clogged with debris, dander, and dust, the blower wheel is working harder to get air through that clogged filter. When this happens, you can experience spots in your home that are cold and hot. It’s also hard to get to the temperature you want in your home.

With reduced air flow through your system, because of the cloged filter, your system’s going to run longer so that your home is heated or cooled and raise your energy use.

4. Dirty Filters Can Lead to Air That’s Unhealthy

When your air filter is clogged, it can let the debris and dust that needs filtering to be sent back into the house. This often leads to chronic allergies and can be especially dangerous for people who have respiratory conditions like asthma.

If you have a lot of chemicals in your house or you have pets, your home’s air quality is going to be much worse if your filter is clogged. You may not notice an occasional sniffle, but as time passes the bad air quality is going to very negatively impact your health.

5. A Clog can Cause Your A/C to Fail

If your air filter’s clogged, can it make your heater stop working? It surely can, and
it’s probably the costliest part of letting your air filter go without changing it. In fact, it could make it break down eventually and mean that you have to replace the system or even just repair it, which can cause a lot of money, too.

Conclusion

These are some of the things that can happen when you don’t replace your air filter in your cooling and heating system. Considering replacing the air filter doesn’t take a lot of time and is affordable, taking the time to do it makes sense rather than having a costly repair or other problems.
