The best way to prevent costly HVAC repairs is to prioritize proper HVAC maintenance. One of the most important AC maintenance tasks is replacing your HVAC filter. Many homeowners don’t replace the filter frequently enough, and others forget to replace it at all. This can lead to high energy bills and expensive repair jobs.
Your HVAC system looks after you all year long, so it’s only fair that you do the same. Read on to learn when and why you need to replace your AC filter.
Why Do I Need to Change My AC Filter?
Your AC filter collects dirt, dust, allergens, pet hair, and more. The longer it’s in place, the more debris it accumulates. As the debris builds up, it decreases the effectiveness of the filter, which eventually lets dirt and allergens flow into your HVAC system and back into your home.
Not changing your AC filter can result in:
- Damage to your HVAC system
- Decreased indoor air quality
- Higher energy bills because the system can’t function optimally
- Decreased HVAC system lifespan
When to Change Your AC Filter
The general recommendation is to change your AC filter once every 30 days. But this recommendation doesn’t take into account the size or type of your filter. Some high-end pleated filters can last for nearly 6 months, making monthly replacements a huge waste of money. Identifying which of the types of HVAC filters your system uses ensures you only replace them when necessary.
Older HVAC systems typically use fiberglass filters, which need to be replaced every 30 days. Most new HVAC systems use pleated filters, which need to be replaced every 90 days, or every 45 days if you have allergies or asthma. Media filters are a high-end type of pleated filter that can last between 6 and 8 months.
How to Choose the Right AC Filter
If you’re worried you won’t be able to find the right filter for your AC unit, take your old filter with you to your local hardware store. Taking your old filter with you ensures you get the right type and size of filter for your AC unit. Even if the hardware store doesn’t stock the right kind, their floor assistants can order the filter or tell you what to look for online.
