Question
Is there actually less wear and tear on your AC unit if you leave the fan running all the time, due to less stopping and starting?
My husband and I argue about the unit wearing out.
Answer
The experts say yes. Frequent stopping and starting is called short-cycling and adds quite a strain to your system.
More importantly, you want your "air conditioning" to run and condition the air (lower the humidity) so that you will feel cooler at a warmer temperature. Thus you get the full efficency from your unit and save money.
