How Much Cooler For Your Air Conditioner
The real question about Air Conditioning is, “How much cooler should an air conditioner keep your house?” Funny thing, in reality, an air conditioner can only keep the temperature in your home approximately 20° cooler than the temperature is outside. Imagine back to the 50’s when air conditioners were becoming popular and think of the difference from previous generations. If it was 90° outside and a family could have the possibility of keeping the temperature in their house at 75°! Game changer in our hot, humid Louisiana weather!! As times have progressed, we can now expect our air conditioners to keep the air in our home at approximately 20° cooler than outside. But wait, what about the temperature and the heat index here in south Louisiana? So, if it is 95° outside, I can expect my home to be set at 75° and nothing is wrong with my air conditioner? Are you sure? Why only approximately 20° cooler? Let me explain how your air conditioner works.
As the air blows over the air conditioners cooling coils, the air’s temperature will drop about 20°. It may only drop the temperature 20°, but it drops the relative humidity and dew point which is more important concerning comfort than the actual temperature. On an extremely hot day, one of the worst things you can do is to set your thermostat temperature even lower than usual in an attempt to make your home cooler. This will make your air conditioner work non-stop and will increase the likelihood of something going wrong.
With this being said, taking measures like insulating your home helps as well. This will allow your air conditioner to not work as hard and usually allow the temperature in your home to decrease more that 20°. How much cooler should your air conditioner keep your home? Your air conditioner should keep the temperature at approximately 20° cooler than the temperature outside. Now go and be cool knowing that central air conditioners were invented!
