For the peak operation of the furnace, keeping a clean furnace is essential.
- The filter is designed to prevent dust, pollen, lint and other debris and contaminants from getting inside the unit.
If the filter becomes clogged, it will no longer be effective. Pollutants will infiltrate the inner workings and obstruct airflow. The buildup will compromise the operation of the motor and all moving parts. The furnace will be forced to run longer and more often, experiencing greater wear and tear and increasing the risk of malfunction. Comfort, efficiency and indoor air quality suffers. The furnace will cost more every month and probably not last as long. While annual maintenance by a licensed and certified HVAC contractor is important to optimize the heating capacity and reliability of the heating equipment, filter replacement is just as vital. The furnace filter needs to be changed at least every ninety days. It’s a good idea to check the air filter every thirty days. There are situations where replacement needs to be more frequent. Whenever the air in the home is especially dusty, such as during home renovations, the filter will clog more swiftly. If there are pets that shed fur and dander, that debris will end up in the filter. If anyone in the household suffers from asthma or allergies, clean air is especially important. Changing the furnace filter helps to improve indoor air quality. When the weather is extremely hot or cold, requiring the heating or cooling system to run constantly, there will be more dust circulating and compromising the filter.
