This Baking Soda Tip Will Keep Your AC In Top Shape During Hot Days

Summer heat waves have brought scorching temperatures throughout the United States, especially in Western and Eastern regions. Coupled with the high humidity, it hasn't been uncommon to see temperatures of 100 degrees Fahrenheit or higher. In the wake of rising temperatures, the National Energy Assistance Directors Association (NEADA) and the Center for Energy Poverty and Climate (CEPC) report that Americans will spend an average of $578 for summer cooling costs. 

With such high energy estimates, running air conditioners efficiently is likely at the top of many consumers' minds. One of the best ways to keep your AC running in top shape is to ensure it has a clean air filter, and a baking soda solution — one of this product's many clever uses – is an excellent way to remove dust and debris.

Air conditioners vary in filter types. Some units, particularly mini-split air conditioners, may have a washable filter, while others use disposable filters, which require changing every 90 days.  You should look at the packaging, owner's manual, or the filter housing to tell whether yours is washable or disposable. If your AC features a washable filter, then you can treat it with baking soda to remove any dust and dander. Once you know the type, you can follow some simple steps to clean the filter.

Washing the filter is one of the most crucial care tips for cleaning an in-house air conditioning unit, and here's how to do it. First, turn off and unplug your air conditioner, then remove the filter from its housing. Check your manufacturer's directions for guidance on where to find the filter — it's often behind a cover or grille.

Next, vacuum your washable AC filter to remove as much buildup as possible. After vacuuming, Hitachi recommends that homeowners mix 1 cup of vinegar with ½ a cup of baking soda, then combine that with a gallon of water. The manufacturer also cautions that the water should be no hotter than 104 degrees Fahrenheit, or the filter may shrink. 

Using a baking soda solution to wash your air filter combines the gentle abrasive nature of baking soda with the power to remove any stale odors. The vinegar helps break down any grease or other sticky debris from the filter.  Use the solution to lightly scrub the air filter with a soft brush, taking care you don't press too hard on the filter's fibers. Alternatively, you can let the filter soak in the solution for up to an hour, then let it air dry completely in a shaded area. Never put a wet air filter back in your air conditioner, as this may damage the unit and lead to mold buildup. 

You can tell it's time to wash your AC filter if you have higher than normal utility bills or you feel your AC takes longer to cool. You should also give it a scrub if you see dust particles in the air, your allergies worsen, or there's visible dust on the air vents. Poor maintenance on your air conditioner can lead to overheating problems and uneven temperatures because your AC works harder for consistent temperature maintenance.

It's best to clean or change your filter every 90 days, though this timeline can vary based on your AC unit, location, usage, presence of smokers, and whether you have pets in the home. Mini split AC manufacturers often recommend consumers clean their AC filter at least every two weeks for the best performance. But if you have a washable filter, then the baking soda solution is an excellent option to keep it in top working condition.
