How Often Should You Change Your HVAC Filter in Summer?

Your air conditioner works hard during August in Midland, NC. As the system moves more air through your home, its filter can collect dust and debris faster. Checking your HVAC filter each month can help protect airflow and keep your home comfortable.

Check Your HVAC Filter Every Month

During summer, inspect your filter about once a month. Many disposable filters need replacement every one to three months, but your home may need a different schedule based on system use and filter type.

Hold the filter near a light source. If light cannot pass through it or the surface looks covered in dust, replace it. You can also ask a technician about filter care during a visit for professional HVAC services.

Some Homes Need More Frequent Changes

Several conditions can make a filter get dirty sooner. You may need to replace it more often if you have pets, several people in the home or nearby construction that creates extra dust.

Long cooling cycles also move more air through the filter. Since August weather can keep your AC system running for much of the day, a filter that lasted three months in spring may need attention sooner in summer.

A Dirty Filter Can Restrict Airflow

A clogged filter makes it harder for air to move through your HVAC system. This can lead to weak airflow, uneven room temperatures and longer cooling cycles.

Restricted airflow may also place added strain on system components. Replacing a dirty filter will not fix every cooling problem, but it removes one common cause of poor airflow and weak performance.

Choose the Correct Filter

Do not assume that the thickest or highest-rated filter is best for your system. A filter that is too restrictive may reduce airflow if the blower was not designed for it.

Check the size printed on the old filter and follow the system manufacturer’s guidance. Ask an HVAC professional for help when you are unsure which filter type fits your system.

Keep Your System Ready for Late Summer

Continue checking your filter each month while your cooling system is in heavy use. If weak airflow, unusual sounds or uneven cooling continue after a filter change, contact Dulin Mechanical Services, Inc. for HVAC services in Midland, NC.
