Why is my Kaysun Amazon Unitario DN4 having a low cooling effect?
- SSusan BrownAug 17, 2025
If your Kaysun Air Conditioner isn't cooling effectively, it could be due to several reasons. The outdoor and indoor unit heat exchangers or the air filter might be dirty, or the inlet/outlet of the units could be blocked. Other potential causes include open doors and windows, direct sunlight, excessive heat sources, high outdoor temperatures, or refrigerant leakage. To address this, clean the heat exchanger and air filter, clear any blockages, close doors and windows, use curtains to block sunlight, reduce heat sources, and check for and repair any refrigerant leaks.
