It’s not something most people think about too excessively. But at [A&E Heating and Air](https://www.aeheatingandcooling.com/), we’re obsessed with it! We want to share with you some things that you may not have known about your air conditioner (AC). We’ve made this list to help you become an informed consumer and get the best out of your purchase. ## Here are four things you might not know about your air conditioner ### **It doesn’t actually produce cold air.** Believe it or not, your air conditioner doesn’t actually add any coldness to the air. Instead, it extracts heat. It does this with a chemical solution known as refrigerant. The heat that is removed is then transferred outside. This leaves cold air, which is circulated through the [ducts](https://www.aeheatingandcooling.com/residential/air-ducts/). ### **It balances the humidity.** Lower humidity means you’re less likely to feel hot. The dehumidifying process helps you breathe [higher quality air](https://www.aeheatingandcooling.com/residential/indoor-air-quality/) and lowers the chance of mold growth. This is one of the reasons that a well-maintained central air conditioning system is the perfect ally for those with allergies. ### **Air filters should be cleaned or replaced regularly.** It’s important to replace your filter routinely. The filter can only hold so much dust and particles before the system becomes clogged. Clogs can cause all sorts of mechanical errors, as well as decrease your air quality while increasing your electric bill. Check the manufacturer’s recommendations to see when you should clean or swap out your filter. ### **Maintenance is a requirement.** You should schedule a [maintenance tune-up](https://www.aeheatingandcooling.com/residential/maintenance/) for your air conditioner at least once a year. Serious problems can go undetected, sometimes till they’re too late to fix. During a service visit, you’ll get an expert pair of eyes to see if there are any problems. Also, your air conditioner will be cleaned to restore the machine’s components and to make sure it runs like new. We at [A&E Heating and Air](https://www.aeheatingandcooling.com/) hope you’ve learned something new from our list. Call us today at 541-645-8188 if you have any questions or would like to [schedule maintenance](https://www.aeheatingandcooling.com/request-service/) for your air conditioner.
