When was the last time you changed your HVAC air filter? Staying on top of this routine task is crucial for both your health and the performance of your HVAC system.

Air filters serve a dual purpose in your home’s heating and cooling system. By capturing dust and other particulates, they help ensure the air you breathe is clean. Simultaneously, they protect your air conditioner, heat pump, or furnace from damage. Experienced HVAC technicians often cite dirty filters as one of the most common reasons for service calls.

So, why do filters get dirty? Homeowners often forget to change them, and when they remember, they might not recall the filter size. If SS&B Heating & Cooling has serviced your residence, we have your filter size on record. Just give us a call!

Four Reasons to Keep Your Air Filters Clean

Studies by the US Environmental Protection Agency reveal that indoor air can be two to five times more polluted than outdoor air. Regularly changing your air filters is essential for your health and your HVAC system’s well-being.

Decreased Energy Consumption

Dirty or clogged filters obstruct airflow, forcing your system to work harder. This can lead to dirty air bypassing the filter and accumulating on the evaporator coil, reducing its heat-absorbing capacity. According to the US Department of Energy, replacing a dirty filter can lower your air conditioner’s energy consumption by 5-15%.

Better Indoor Comfort

A dirty air filter restricts proper airflow through your home, leading to rooms that don’t get enough warm or cool air to keep you comfortable. Keeping your filters clean can also reduce the noise from your supply grilles, adding to your comfort.

Improved Air Quality

Small particulates in indoor air can cause health issues, from eye, nose, and throat irritation to more severe respiratory problems. Filters with a Minimum Efficiency Reporting Value (MERV) rating of 13 or above can effectively remove small particles. Additionally, filters that carry the CERTIFIED asthma & allergy friendly® mark meet specific standards for allergen reduction. Beyond HVAC filters, high-efficiency options like certified whole-home air cleaners can also be beneficial.

Reduced Risk of Mechanical Issues

Dirt and debris bypassing the filter can accumulate on system components, leading to problems such as overheating blower motors, iced-up evaporator coils, short-cycling units, and dust buildup in ductwork. These issues can cause system downtime and expensive repairs, making regular filter replacement a cost-effective maintenance task.

How to Change Your Air Filters

Even if you purchase filters rated for more than 30 days, it’s a good idea to check them monthly during heavy usage periods like summer or winter. Replacing a dirty filter is simple:
Turn off the system using the thermostat, circuit breaker, or switch.
Locate your filter(s). They may be on the side, top, or bottom of your air handler or mounted in the ceiling or wall behind a hinged cover as part of your duct system.
Open the access cover and remove the old filter. Note the arrow on the filter indicating the correct orientation for airflow.
Insert the new filter(2) with the airflow arrow pointing in the right direction and close the access cover. Filters are designed to fit snugly, so be careful not to bend or tear them. If you use a reusable filter, clean it thoroughly with a gentle brush and mild detergent before replacing it.
