Why is my SPT WA-8070E not cool enough?
- JJason MeyersJul 30, 2025
If your SPT Air Conditioner isn't cooling sufficiently, several factors could be at play. First, ensure all windows and doors in the room are closed to prevent warm air from entering. Next, identify and remove any heat sources that might be affecting the unit's performance. Verify that the exhaust air duct is properly connected and free from obstructions or sharp bends. Check the temperature setting and lower it if it's set too high. Finally, a blocked air filter can also reduce cooling efficiency, so clean the air filter.
