How a Dirty Filter Affects AC Efficiency

//

At the very least, you should change the air filter in your HVAC system about once every three months. You should check it monthly for signs of visible buildup and replace it if you see dirt accumulating, though. If you neglect this task, the filter in your HVAC system will become clogged with dirt and dust. As a result, it’ll decrease AC efficiency in your Paradise, Nevada, home.

Forces Your System to Work Harder

When the air filter clogs, it’s more difficult for your AC system to pull air through it. The entire air conditioner will have to work harder to suck air through the accumulated dust, dirt, dander and other irritants. This, in turn, causes your electricity usage to rise. As a result, you’ll pay more for the same level of comfort that you could get with less energy if the filter was clean.

Freezes Your Evaporator Coils

The evaporator coils in your air conditioner absorb heat from the house as air blows over them. If your air filter clogs, it could decrease airflow, which might leave the refrigerant in your evaporator coils much colder. As a result, the coils will freeze and your system will shut down. It’s extremely inefficient for your system to cycle on and off as the coils freeze and thaw. Avoid this issue with a fresh air filter.

Causes the System to Run More Often

The diminished airflow that a clogged filter could cause isn’t always enough to keep your house cool. As a result, you may have hot and cold spots throughout your living space. This typically causes your air conditioner to cycle on and off more than it should. This cycling uses more energy than running at a low capacity for a longer period of time. Your AC system will run inefficiently when you force it to do this.
