Air conditioning can contribute to better air quality in your home by filtering and dehumidifying the air.
High humidity levels contribute to the growth of mold and mildew, which can cause serious respiratory illness. A properly functioning air conditioner will maintain a healthy humidity level in a range from 20 to 50 percent.
If your air conditioner is cooling the house but leaving you cold and clammy, it's because it is cycling through the cooling function and turning off before it has removed the moisture from the air. The most common cause of this is an oversized unit, which actually increases the health risk because mold can build up in the unit itself, then circulate the pollutants and bacteria throughout the house.
Additionally, air conditioners can cause a loss in indoor air quality if they're not properly maintained. An improperly maintained air conditioner will simply recirculate pollutants, contaminants, dust, pollen, allergens and bacteria over and over throughout your house. It is important that you follow manufacturer instructions regarding the proper maintenance of your air conditioner or contact an HVAC professional to perform regular routine maintenance on your system.
If you are experiencing ongoing problems with your indoor air quality, regardless of whether or not your air conditioner is a contributing factor, one solution you should consider is getting an air purifier. These units use powerful technologies to attract, trap and eliminate tiny particles of all types from the air in your home. Air filters will filter out dust, pollen and other air pollutants, and should be cleaned before first use at the beginning of the season and monthly in areas and times of high pollen release. To maintain the optimal function of your system, make sure to remove the filter and clean it according to manufacturer directions on a regular basis. It doesn't take that long for an air purifier's filter to become clogged with trapped particles, so be sure to check it often and clean it whenever it starts to fill up.
Some air conditioning units are featured with additional dehumidifying and air cleaning functions that may or may not be necessary. A well-designed and properly functioning air conditioner should perform these functions if they are properly sized and maintained.
