Why is my Fujitsu Air Conditioner not cooling or heating properly?
- TTodd LawrenceAug 3, 2025
Several factors can lead to poor cooling or heating performance in your Fujitsu Air Conditioner. First, check if the air filter is dirty. Ensure that the intake grill or outlet port of the indoor unit isn't blocked. Verify the room temperature is appropriately adjusted. Also, check for open windows or doors, strong sunlight, other operating heating devices or computers, or too many people in the room. Make sure the fan speed isn't set to 'QUIET', as this mode prioritizes noise reduction over performance. Check if the OUTDOOR UNIT LOW NOISE mode is enabled, and if you have a Demand Response arrangement with your electric company.
