This isn’t new information—pretty much any HVAC professional you talk to is going to say it’s necessary that you replace your Nederland, TX air conditioning system’s air filter every 1-3 months during periods of use, depending on the level of contaminants in your home and the type of air filter you have. If you have a reusable filter in your AC—which is pretty common in small, portable systems, then you’ll want to clean it and let it fully dry before putting it back in.
But, why? If you don’t have indoor air quality problems, is it really that important that you change out or clean your air filter on a regular basis? Well, yes—because the air filter is not necessarily there for your health, but rather the health of your air conditioner.
