Modern air conditioners are designed to last for years, often running every day for months at a time. As long as the air conditioner receives regular seasonal maintenance and is in good working order when it's turned off, you should have no problem turning it back on. However, some precautions still need to be taken when you are about to turn off an air conditioner for a long time or are preparing to turn it back on. It's important to clean any dirt or debris around the unit and check for cracks or other damage each spring before turning the system back on for summer use.
Belt drives help operate many parts of the electric coils and compressors in central air conditioning systems; belt drives also operate the fans in window units. After several years without using it, a capacitor can lose its ability to produce the voltage needed to turn on the air conditioner. If you notice any signs of trouble when you turn the air conditioner back on, don't hesitate to call a professional. It's better to be safe with proactive air conditioner maintenance than to risk costly major repairs a few months later.
In conclusion, modern air conditioners are designed to last for decades and should be able to withstand long periods of downtime without problems, as long as they receive regular maintenance. Cleaning any dirt or debris around the unit and checking for cracks or other damage each spring before turning the system back on is essential for keeping your AC unit in good working order. If you spot any signs of trouble when you turn the air conditioner back on, don't hesitate to call a professional. Taking these steps will help ensure that your AC unit is in good working order and will last for many years.
