Steps for Changing a Furnace Filter
An air filter is a crucial component of your furnace that does the critical role of filtering out any particulate contaminants to maintain good air quality. It is also one of the parts that need regular maintenance. Thanks to the easy steps involved in replacing an air filter, you can do it yourself. Here are some important steps involved in changing a furnace filter.
Switching the Furnace Off
When working on any electrical appliances, including your HVAC unit, safety is very important. Switching the furnace off protects you from the potential risk of an electric shock. It also protects the system from accidentally turning on and sucking unfiltered air into the ducts.
Locating the Filtering Unit
The next step involves finding the filtering unit, which is located in different positions depending on your HVAC system’s brand and design. Should you have some trouble finding the unit, you may have to refer to the service manual. You may then locate the access door and carefully open it.
Determining the Right Filter
You should always replace your old filter with an exact match in terms of size and shape to ensure the proper functioning of your HVAC system. One way to ensure that the new unit matches the old one is to check the air filter size, which is usually indicated in the dimensions of length, width and thickness. Before replacing the old filter, if your filtering unit allows directional airflow, you should note its orientation.
Removing and Installing the New Unit
After removing the old air filter, you should check the filter box for debris, dust, cobwebs and other particulate material that may obstruct airflow. After that, slide the new air filter in place and lock the access panel for a tight fit. You can then switch on the furnace and observe to ensure that there is smooth airflow.
