Do you feel like you have to change your air filter more often than normal? It could be something as simple as usage or the type of filter you choose. Or there might be a problem that requires air conditioning repair in San Jose, CA. Here we will explain what is “normal” when it comes to changing the air filter and what might be causing it to get dirty so fast.
How Often Should I Change My HVAC Filter?
Remember, these timelines are just recommendations, But on average, you should check your filter every month, and replace it every three months when it gets dirty. You will probably change your filter more often during summer and winter because those are the times your HVAC system runs most often.
How often you change your filter also depends on the Minimum Efficiency Reporting Value (MERV). This tells you how efficiently the filter removes particles. Higher ratings mean the filter catches more pollutants and you will need to replace it more often. The MERV rating should be printed on the packaging as well as on the side of each individual filter.
Another factor is the type of filter you have. The most affordable are flat-panel fiberglass filters. They are usually about one inch thick with filters made of spun fiberglass. You will probably need to replace these once a month. Reusable electrostatic filters trap pollutants with negatively and positively charged fibers. You will want to vacuum or wash these filters about once a month. Pleated filters, made from paper or polyester, should be changed every two or three months.
Reasons Your Filters Get Dirty So Fast
Here are just a few of the reasons you might be changing your filter more often:
You Have Extra Foot Traffic
Think about it. With more people and pets comes more dirt, dander, hair, fur, and dust. So it makes sense that if you have visitors staying with you for a prolonged period of time it will equate to more debris getting stuck in your filters. But better that than having it constantly floating around your home.
The Fan is Set to “ON”
Before calling for air conditioning repair it is important to check the thermostat. We get so many service calls for problems only to arrive and find out it is just set to the wrong settings. If you constantly run the fan that means the air is always cycling and the filter is pulling particles 24/7. You want to set the fan to “AUTO” so it only runs when the system is signaled to cool your home.
You Have Leaky Ducts
Leaks in the ductwork can pull extra dirt from the attic, crawlspace, or basement into the home. But a dirty filter will probably be the least of your problems if the leak is not repaired. You should call an HVAC professional to have your ducts sealed.
If you are replacing your filters more and more often it might be time to call for air conditioning repair in San Jose, CA.
