How Do You Change a Furnace Filter?
Have you changed your furnace filter yet this fall?
As the weather continues to grow colder in Vancouver, your furnace will likely be running continuously for the next few months. It is important to ensure you’re using a clean furnace filter. Energy Star recommends that you change your filter every month, especially during the winter months when your furnace gets the most use. At the very minimum, you should change the filter every 3 months.
Changing your furnace filter is important. Here’s why:
- It maintains healthy air quality in your home
- Extends the life of the furnace
- Maximizes the efficiency of the unit and keeps heating costs down
Change your Furnace Filter
Step 1: What kind of furnace filter do you have?
Start by turning off your furnace and locating the furnace filter compartment. Next, remove the existing filter. Before you remove it completely, look for an arrow on the filter indicating the airflow direction. Use a permanent marker to draw the airflow direction on the outside of the furnace. Then, take note of the furnace filter size. This will be printed on the cardboard frame.
If the filter has a plastic or metal frame, then it is a reusable filter. That means it can be cleaned and reused. We recommend cleaning it with a vacuum and water, ideally outside. Let the filter dry completely before reinserting.
Step 2: Get the Right Replacement Filter
You can purchase replacement filters at hardware stores and online. Make sure to purchase the exact same size and also ensure the airflow arrows on the side are pointing the right way. The size will be printed on the edge of the filter.
Step 3: Install the New Filter
When installing the new furnace filter, look for marking that will tell you which side should face the furnace. Next, slide the filter back into the compartment and replace the cover. We recommend keeping a record of the date you replaced the filter so you will know when it’s due to be changed again in the future.
In addition to regularly changing your filter, it’s important to perform furnace maintenance prior to the start of the winter season.
