Why is my Haier ADH200H1ERG Air Conditioner cooling or heating not sufficient?
- JJorge McdowellAug 9, 2025If your Haier Air Conditioner isn't cooling or heating sufficiently, try these steps: * Adjust the thermostat to your desired setting. * Check and clean the air filter if it's dirty. * Make sure all doors and windows are closed. * Remove any obstructions blocking the air inlet or outlet. * If in heating mode, ensure the swing louver is horizontal.
