When Did You Last Check Your Air Filter?
On a more technical side, your furnace may stop working because of internal buildup. When was the last time you changed your air filter?
When the filter is full, clean air cannot pass through it. This means there is less air to distribute, making it harder for your furnace to distribute heat.
Homeowners can check for themselves whether or not the air filter is old and full.
Dirty air filters negatively impact the central air system in many ways. If you haven’t, you should make a habit of regularly replacing the air filter. This keeps indoor air clean, reduces energy spending and preserves the entire central air system.
