Portable AC not cooling at all

It's frustrating when your portable AC unit doesn't seem to be cooling your room effectively.

There are several steps you can take to improve its cooling performance:

Proper Installation: Ensure that the portable AC unit is installed correctly and that the exhaust hose is securely connected to the window or an appropriate exhaust port.

If the hose is leaking hot air back into the room, it will reduce the unit's effectiveness.

Seal Any Air Leaks: Check around the windows and doors for any gaps or leaks where hot air from outside can enter and cool air can escape.

Seal these gaps with weatherstripping or caulk to maintain a better seal.

Use a Fan: You mentioned you have a ceiling fan.

Running a fan alongside the AC can help distribute cool air more evenly throughout the room, making it feel cooler.

Make sure the ceiling fan is rotating counterclockwise during the summer months to create a cooling breeze.

Close Curtains or Blinds: Even though you have blackout curtains, consider closing them during the hottest parts of the day to block out as much sunlight as possible.

This can help reduce the heat entering the room.

Limit Heat Sources: Turn off any unnecessary heat sources such as lights, electronics, and appliances when the AC is running.

These can contribute to the overall heat load in the room.

Maintain the AC Unit: Regularly clean or replace the air filter in your portable AC unit to ensure proper airflow.

A dirty filter can reduce cooling efficiency.

Also, make sure the unit's vents and coils are clean and free from dust and debris.

Size of the AC Unit: Ensure that the BTU (British Thermal Units) rating of your portable AC unit is appropriate for your room size.

In your case, it seems like the unit should be sufficient for a 550 sq ft room, but it's worth double-checking the specifications.

Thermostat Setting: Setting your AC to 61 degrees is quite low, and this can strain the unit.

Try setting it to a more moderate temperature, such as 72-75 degrees, and see if the room cools down effectively at that level.

Extremely low settings can lead to the unit running constantly without achieving the desired temperature.

Give It Time: It can take some time for a portable AC unit to bring the temperature down, especially if the room is very hot to begin with.

Give it a few hours to see if it starts to make a difference.

If you've tried all these steps and are still not getting the desired cooling, it's possible that the unit may have a malfunction, or it may not be adequately sized for the room.

In that case, you may want to contact the manufacturer's customer support or return the unit to the store if it's still under warranty.
