Should I Leave the AC On When Not Home?
Leaving the air conditioner running while you are away can protect pets, electronics, and humidity-sensitive belongings in hot or humid climates, but it also increases energy use and wear on the system. The right choice depends on how long you will be gone, local weather, your home’s efficiency, and whether anyone or anything heat-sensitive stays behind. This guide helps you weigh the trade-offs and choose the most practical approach.
