Air conditioners are meant to be used as needed to maintain a comfortable indoor temperature. When it’s hot outside, and you need to cool your home, you can use your AC as much as you like. If you want to save money on your energy bills, though, there are some strategies you can use to minimize how much you run your air conditioner without making your home too hot or humid. This includes using ceiling fans, investing in a programmable thermostat, and getting your AC serviced regularly.
