Changing Furnace Filters: Why Bother?

When it comes to improving your home’s comfort, little things like changing your furnace filters matters. Apart from keeping off excessive dirt and debris from building up in the system, it can also prevent indoor air quality problems and premature failure of the component. Doing this regularly also keeps the system working efficiently, which then translates to lower electricity bills.

What do air filters do?

The main job of your furnace’s filters is to keep dust and dirt from accumulating inside the duct system and air handler. When air runs through a clean or new filter, it can reduce or remove dirt and allergens before warming your air and distributing it to the rooms. This can improve the system’s efficiency while keeping your house comfortable.

What’s the harm of not replacing them?

Without regular replacement, the air filter is likely to get clogged, which will then obstruct the airflow through the unit.

This can then increase your utility bill and put additional stress to the parts, resulting in premature wear or frequent repairs. This can also shorten the life of the unit.

Apart from obstructed airflow and increased utility bill, dirty filters can also create several problems and safety concerns. These include:

  • Clogging and compromised air quality
