Why does my DeLonghi Air Conditioner work but not cool sufficiently?
- MMark MorrisAug 1, 2025
Several factors can cause inadequate cooling. First, check if any windows are open and close them. Remove any heat sources like heaters or lamps from the room, and ensure the room isn't overcrowded. Make sure the exhaust hose is properly connected and that the thermostat isn't set too high—lower the thermostat setting. Also, a clogged air filter can reduce cooling efficiency, so clean the filter. Finally, consider whether the air conditioner's capacity is suitable for the room size.
