Frequently asked questions
What should I do if my cassette AC unit stops cooling?
If your cassette AC unit is not cooling, first check your thermostat settings to ensure it is set to the correct mode and temperature. If the problem persists, it could indicate issues such as a refrigerant leak, compressor failure, or a faulty fan. It is best to contact an F-Gas certified engineer for a professional diagnosis and repair, as attempting to fix it yourself could void warranties or be unsafe.

Is regular maintenance necessary for cassette AC units?
Yes, regular maintenance is highly recommended for cassette AC units. It helps prevent common faults, improves energy efficiency, extends the lifespan of the unit, and ensures optimal performance. Maintenance typically involves cleaning coils, checking refrigerant levels, inspecting electrical components, and testing overall system functionality. This proactive approach can significantly reduce the likelihood of unexpected breakdowns and costly repairs.
What causes water to leak from my cassette AC unit?
Water leaks from a cassette AC unit are often caused by a blocked or overflowing condensate drain line. This can be due to a build-up of algae, dirt, or debris. Other potential causes include a frozen evaporator coil (often due to low refrigerant or restricted airflow), a cracked drain pan, or incorrect installation. Our engineers can quickly identify the source of the leak and carry out the necessary repairs to prevent further water damage.
