Why is my Haier ESAQ406 Air Conditioner not cooling as it should?
- PPaul HarrisAug 15, 2025
Your Haier Air Conditioner might not be cooling properly due to several reasons. Check if anything is blocking the front of the unit, such as curtains, blinds, or furniture. Ensure the temperature control is set correctly by turning it to a higher number. Clean the air filter, doing this at least every 30 days. Remember that when first turned on, the unit needs time to cool the room. Also, check for open furnace registers or cold air returns, and refer to the 'Air conditioner freezing up' section if the cooling coils are iced up.
