Why is my Vaillant VAM 6-050 W2N Air Conditioner not cooling or heating enough?
- JJackson OliverJul 31, 2025
Insufficient cooling or heating in your Vaillant Air Conditioner can occur due to several reasons. Check if doors or windows are open and close them. Remove any nearby heat sources. Ensure the thermostat is set correctly for cooling or heating mode. Clear any obstacles blocking the air inlet or outlet. Wait to see if the ambient temperature reaches the set level. Clean the air filter, which should be done every 15 days. If direct sunlight is entering through the window during cooling, use a curtain.
