As the chilly winter months approach, homeowners often wonder if they can leave their window air conditioners in place during the off-season. Leaving a window AC unit during winter can have both advantages and disadvantages, so it’s important to weigh the pros and cons before making a decision.

Advantages of Leaving a Window AC Unit

• Prevents Drafts: A window air conditioner can help block cold drafts from entering your home through the window opening.
• Protects the Window Frame: Leaving the AC unit in place can help protect the window frame from moisture and cold damage.
• Convenience: It’s more convenient to leave the AC unit in place than to remove and store it, especially if you live in a cold climate where winter weather can make it difficult to access the window.

Disadvantages of Leaving a Window AC Unit

• Condensation: The cold winter air can cause condensation to form on the AC unit, which can lead to mold growth and water damage.
• Frozen Components: If the temperature drops below freezing, the AC unit’s components can freeze and become damaged.
• Increased Energy Consumption: Even when turned off, a window AC unit can still draw a small amount of power, increasing your energy consumption.

• Disconnect the Power: Turn off the circuit breaker or unplug the AC unit to prevent it from drawing power.
