Why is my Costway Air Conditioner not cooling properly?
- EElizabeth ShermanAug 3, 2025
If your Costway Air Conditioner isn't cooling well, several factors could be the cause. Direct sunlight can impact cooling, so close the window curtains. Open doors and windows, a crowded room, or other heat sources can also affect performance; try closing doors and windows and removing extra heat sources. A dirty filter can restrict airflow, so clean or replace the filter. Finally, check for any blockages at the air inlet or outlet and remove any obstructions.
