Why is my Proline PAC1500 not cooling well?
- BBeverly RobertsAug 7, 2025
If your Proline Air Conditioner isn't cooling well, several factors could be at play. First, ensure the air filter is clean; if it's blocked with dust, turn off the unit and clean the filter. Check that the exhaust hose is correctly connected and free from blockages. Also, verify that the temperature setting isn't too high by decreasing the set temperature. Make sure all windows and doors are closed to prevent warm air from entering. The unit's cooling area should be appropriate for the room size, and any heat sources should be removed if possible. If the unit is low on refrigerant, call a service technician to inspect the unit and top off refrigerant.
