Why is my Tectro TP 3020 not cooling well?
- MMelissa WrightAug 6, 2025
If your Tectro Air Conditioner isn't cooling effectively, several factors could be the cause. First, ensure that the air filter isn't blocked with dust or animal hair; if it is, turn off the unit and clean the filter according to instructions. Check that the exhaust hose is correctly connected and free from blockages. Also, the temperature setting might be too high, so try decreasing it. Confirm that all windows and doors in the room are closed, and that the room size is appropriate for the unit's cooling capacity. Finally, consider removing any heat sources from the room. If none of these steps help, the unit might be low on refrigerant, requiring a service technician to inspect and replenish it.
