When air conditioner filters are not cleaned properly or changed, they become a party place for fungi and bacteria. These organisms tend to cause respiratory problems in humans like pneumonia or Legionnaires disease. You’ll notice mould building up inside the air conditioner’s vent so take the filter out and inspect it properly. You might also notice your running nose, cough and so on going away once you get out of your home. Hairfall, flakey skin, extreme dryness in skin and scalp and so on are some signs too. This is a big reason to search and call air conditioning contractors near me in Reston for a cleanup or repairs for better health.
