If your MrCool Air Handler won't turn on, the first thing to check is whether it's properly connected to a power supply; make sure it is securely connected. Also, verify that the circuit voltage is within the rated scope to rule out low voltage issues. Lastly, inspect the fuse and circuit breaker; replace the fuse or reconnect the breaker if necessary.
Why is my MrCool Air Handler not cooling or heating properly?
If your MrCool Air Handler isn't providing adequate cooling or heating, several factors could be at play. Start by ensuring that the air inlet and outlet aren't blocked by any obstructions; clear them to ensure proper airflow. Next, check your thermostat settings to make sure they're appropriately adjusted for your desired temperature. Also, make sure that doors and windows are closed, and draw any curtains or louvers to block direct sunlight. Reduce any excessive heat sources within the room. Finally, a dirty filter screen can restrict airflow, so be sure to clean the filter.
