HVAC system maintenance is important both for functionality and for home comfort. Changing your furnace filter is one way to keep things running smoothly and efficiently.
Why is it so important to change your furnace filter?
1. It saves money.
When your air filter is functioning properly, your HVAC system runs more efficiently. This conserves energy, lowering your utility bill. It also prevents the need for future repairs, which makes the upfront cost of replacement filters much more appealing.
2. It increases your furnace’s lifespan.
A clogged filter can result in an overworked system, reducing your furnace’s lifespan and turning “replacement time” into a necessity rather than an option.
3. It improves indoor air quality.
An old furnace filter loses its ability to trap pollutants and allergens. Dirty air is circulated, causing health concerns. A new filter captures these allergens, making the air being circulated safe to breathe.
4. It reduces the need for repairs.
Regularly changing your furnace filter keeps other problems at bay. A clean filter means fewer repairs.
5. It increases energy efficiency.
As already mentioned, an efficient system produces efficient energy use. A clean filter helps prevent energy waste.
6. It keeps the furnace and your home clean.
Do you enjoy breathing fresh air? That is the air filter’s job. A clean filter results in clean air, which results in happy skin, eyes, and lungs.
How often should you change your furnace’s air filter?
There are several principles you should consider when deciding whether or not you should change your furnace filter.
- High-efficiency filters do not need to be changed as often as filters with low MERV ratings.
- Your furnace filter will likely need to be changed in peak seasons of use, such as winter (heating) and summer (air conditioning). During these periods of frequent system use, you should check your filter monthly and replace it as needed.
- Households containing pets or smokers typically require regular filter changes. More contaminants in the air (pet hair, dander, smoking byproducts, etc.) result in clogged filters.
Look for a manufacturer recommendation on your air filter’s packaging that lists the filer’s standard lifespan.
How else can you protect your HVAC system?
On top of changing your furnace filter regularly, you should schedule routine HVAC tune-ups by a licensed professional. Preventative maintenance is the best way to avoid problems and save money on future repairs.
