Answer:
When a Fujitsu mini-split isn’t blowing cold air, we’ve found that it’s often caused by simple issues like dirty air filters, incorrect thermostat settings, or refrigerant problems. In our experience, many customers don’t realise that a clogged filter can restrict airflow, preventing the unit from cooling effectively. Additionally, ensure the thermostat is set to “cool” mode with a temperature lower than the current room temperature. If these basics don’t resolve the problem, it might be due to low refrigerant levels or a refrigerant leak, which would require professional attention.
More On: Why Is My Fujitsu Mini-Split Not Blowing Cold Air?
One of the most common reasons for cooling issues is improper maintenance. Fujitsu mini-splits are efficient and reliable, but they require regular cleaning and servicing to perform at their best. Dirty coils, blocked airflow, or even debris around the outdoor unit can severely impact cooling performance. We always suggest checking the outdoor unit to ensure it’s clear of dirt, leaves, or obstructions.
Another factor to consider is whether your mini-split is operating in conditions that exceed its cooling capacity. For example, if your room has large windows that let in a lot of sunlight, it could place extra strain on the system. If the system appears to be running but not cooling, there may also be an issue with the compressor or sensors. In such cases, it’s best to call a certified HVAC technician to inspect the unit and make necessary repairs.
