It’s an easy thing to forget about, but the filter in your HVAC system has a big job. Changing the filter regularly is a critical task to help prolong the life of your system and keep the air in your home or office clean.
What happens if you leave a dirty filter in your system for too long? Is it really that big of a deal? Before you try and “save money” by skipping filter replacements, here’s how dirty filters impact your HVAC system.
Why Clean Filters Matter
The air filter helps keep dirt and debris from entering your air conditioning and heating system. As the system pulls air in and circulated it throughout your home, the HVAC filter helps push clean air through the vents and into every room.
However, when the filter becomes dirty and clogged, the air quality in your home suffers. Larger dust, dirt, and allergen particles can find their way past the filter into your air ducts, then disperse through the vents into the air you breathe.
Air filters also help protect your system. When larger particles enter your AC and furnace unit, they can clog the components and create hazards or malfunctions. One of the simplest ways to avoid major (and expensive) repairs is to stick to a routine of changing your filter several times throughout the year.
How Do I Know If I Have a Dirty HVAC Filter?
Can you remember the last time you changed the filter? If you’re wondering, “is my HVAC filter dirty,” it’s probably time to change it!
We recommend setting up a reminder to change your filter two to four times a year, depending on the type of filter you use. As your filter begins to clog, you might notice signs like:
- An increase in sneezing or coughing due to reaction to more allergens in the air
- Your HVAC system runs longer without cooling or heating
- The system won’t run at all
- Your energy bills seem higher
- You notice more dust collecting around vents or on furniture
As soon as you notice any of these issues, replace the air filter right away. However, to prolong the life of your HVAC system and reduce allergy or asthma attacks, don’t let the air filter become clogged. Proactively change the filter to maintain the air quality in your home and protect your system.
Choose the Right Filters
What’s the best HVAC for your system? Check your unit to find the right size for replacement air filters.
Depending on your needs, select the MERV rating to help your circulate cleaner air. A higher MERV rating removes smaller particles than lower MERV rated filters.
