There are a few things you can do to prevent reverse cycling in your home: nn-Make sure your furnace is the proper size for your home. If it is too small, it will have to work harder to heat your home, which can cause it to cycle more frequently. n-Have your furnace serviced regularly to ensure it is operating efficiently. n-Install a humidifier to help maintain the proper level of humidity in your home. n-Make sure all doors and windows are sealed properly to keep the warm air in and the cold air out. n-Use a programmable thermostat to help regulate the temperature in your home.
