The filter for your HVAC system plays an important role in protecting your equipment, promoting healthy indoor air quality, and ensuring system efficiency. That’s why routine filter changes are a critical part of regular HVAC maintenance.
In this article, the HVAC experts at Clay’s Climate Control cover how to locate your HVAC filter, along with tips for identifying filter size and an overview of the importance of frequent changes.
Common Air Filter Locations
The location of the air filter in your South Jersey home will vary depending on what type of HVAC system you have. Follow this guide:
- Central AC: The filter for your central air is usually in the return duct in the wall or ceiling’s return vent.
- Furnace: To find your furnace filter, look in the blower compartment or in a filter slot located where the return duct meets your furnace.
- Ductless mini-split: Filters for these systems are located inside the indoor air units that are mounted to your walls. They can be accessed through the front panel and may be a washable mesh screen instead of a disposable filter.
Tips for Identifying Your Filter Size
When changing your filter, it’s important to purchase a replacement that is the proper size. There are a few ways you can determine this:
- Check the existing filter. It will often have the size printed on the frame.
- Measure the length, width, and thickness of your current filter and round up to the nearest whole inch.
- Check the HVAC manual or manufacturer label for recommended filter sizes.
Why Changing Filters Matters
HVAC experts tend to recommend filter changes at least every three months and up to every month for those who have allergies, asthma, or several pets. This is an important part of heating and cooling maintenance, as dirty filters can lead to a wide range of issues, including:
- System malfunctions: Dirty air filters will restrict airflow to your system and can cause it to overheat, freeze up, or cycle improperly.
- Shorter lifespans: Dust and debris buildup will cause your system to work harder than it has to, causing extra wear and tear and shortening its lifespan.
- Reduced comfort: An HVAC system without proper airflow will create hot and cold spots throughout your home that negatively impact your comfort.
- Increased energy bills: Dirty filters can cause energy bills to skyrocket as your system works longer or harder to keep your home at the ideal temperature.
- Health issues: Continuing to use dirty air filters allows your HVAC system to recirculate dust and allergens that can cause respiratory issues.
