Signs your unit needs attention
Don't ignore these warning signs — early intervention prevents costly breakdowns.
Not cooling or heating
If your unit runs but doesn't reach the set temperature, it may have a refrigerant leak, dirty coils, or a failing compressor.
Unusual noises
Rattling, grinding, or squealing sounds indicate loose components, a failing fan motor, or debris in the unit.
Water leaking indoors
Indoor water leaks are usually caused by a blocked condensate drain or a frozen evaporator coil.
Bad odours
Musty smells indicate mould or bacteria growth in the coils or drain pan. A chemical clean will resolve this.
High electricity bills
A sudden increase in electricity consumption often means the unit is working harder than it should due to dirty coils or low refrigerant.
Unit won't start
Electrical faults, PCB failures, or tripped circuit breakers can prevent the unit from starting. Do not attempt DIY electrical repairs.
