Is the Furnace Filter the Same as the Air Conditioning Filter?

November 30, 2018

The heating and cooling system in your Fayetteville home is very complex, and it’s likely that you have a lot of questions about how your system works and its most important parts. For instance, if you’re trying to understand your system, you may want to know if your furnace filter and AC filter are the same. Find out if there is a difference between your AC and furnace filter and learn why filters are so important to your HVAC system.

One Filter for Your Whole Home

While many people refer to air conditioning and furnace filters as if they’re different, this is not the case. Your furnace and your air conditioning system use the exact same filter, so there’s no need to worry about purchasing separate filters for each piece of equipment.

Where Does the Filter Go?

Now that you know that the AC filter and furnace filter are one and the same, you may have questions about where to install the filter in your home. Your filter’s installation point will largely depend on how your system is set up. In a traditional HVAC system, your air filter is usually installed between your HVAC unit and your return duct. This can change, however, depending on where your unit is installed.

If your HVAC unit is installed in your attic, for example, then your filter may be installed in an air vent instead of a return duct. Ask your HVAC professional how your system is set up, so you can know where your filter is installed.

Replacing Your Filter

The air filter in your HVAC system works to remove particles from the air in your home and to keep your air conditioner and furnace running smoothly. Eventually, your filter will accumulate a lot of dirt and debris and will need replacing. Generally, you should replace your filter at least once a year.

If you need to install a new filter in your HVAC system or need help with maintenance, call Cape Fear Air Conditioning, Heating, & Electrical Company, Inc. today at (910) 216-9394.
