Why is my AC not cooling?Updated 23 days ago

There are several factors that impact window AC cooling functionality. Here are some common reasons and how to fix them.

1) Thermostat setting: Make sure your AC is set to "cool" mode and the temperature is several degrees lower than the room temperature.

2) Dirty Air Filter: A clogged filter (the reusable mesh filter) restricts airflow, reducing cooling efficiency. Remove and clean the filter according to instructions.

3) Dirty Coils: Behind the mesh filter, the coils can prevent cool air transfer if there is dust or grime. Gently vacuum or use compressed air to clean them. 

4) Improper Size BTUs: An oversized AC can short cycle (cool too fast without dehumidifying), while an undersized one will struggle to cool the room. Both of these issues can eventually cause the AC to become ineffective and will void the warranty. It's crucial to pick the correct BTUs for maximum cooling efficiency. 

5) Installation: Make sure your unit is installed according to our installation guide. Make sure nothing is blocking or impacting airflow (such as curtains) and all gaps around the AC are sealed.

6) Outside Temperature: In most cases, a window AC will not cool beyond 15-20 degrees of the outside temperature. During extreme heat, use a fan to help circulate the cool air better and keep your shades drawn and windows closed to help keep the cool air in.

7) Outside Humidity: If you are in a location that is experiencing high humidity, that will reduct cooling efficiency. Ensure all gaps are sealed and try to keep doors closed.

If there is cold air coming out of the vents, your AC is functioning. If you continue to experience issues beyond this, please reach out to [email protected] for help
