The question of whether or not turning off your air conditioner in winter will save you money is a tricky one. It all depends on the outside temperature and the efficiency of your AC unit. In some cases, it may be beneficial to turn off the air conditioner during the day, while in other cases it may be more expensive. It all depends on how efficiently your unit operates and the climate in your home.
Air conditioners work best to cool and dehumidify when they're running at full speed, so running the system around the clock requires more energy overall. When deciding whether or not to turn off your AC in winter, it is important to consider the climate in your home and how efficiently your unit operates. Ultimately, it is up to you to decide whether or not turning off your air conditioner in winter will save you money.
