AC problems we fix

AC Not Cooling / Low Cooling

AC Not Cooling / Low Cooling

The unit runs but the room barely cools — often low gas, a choked filter or a weak compressor.

AC Slow Cooling

AC Slow Cooling

Cooling is noticeably slower than usual and the AC struggles to hold the set temperature.

AC Not Turning On

AC Not Turning On

The AC is completely dead — no response from the remote or the indoor unit.

AC Not Working

AC Not Working

The AC powers up but does not cool or behaves erratically during operation.

AC Not Functional

AC Not Functional

The system trips, restarts or shuts off on its own and will not run a full cycle.

AC Failed Compressor

AC Failed Compressor

The compressor hums, trips or stays silent — the heart of the AC needs diagnosis or replacement.

AC Gas Leakage

AC Gas Leakage

Refrigerant leaks starve the coil, so cooling drops off and the unit runs non-stop.

AC Water Leakage

AC Water Leakage

Water drips from the indoor unit — usually a blocked drain, iced coil or tilt problem.

AC Ice Formation

AC Ice Formation

Ice builds up on the coil or pipes, choking airflow and cooling.

AC Coil Problem

AC Coil Problem

A dirty, corroded or damaged evaporator/condenser coil kills efficiency and cooling.

AC Blockage

AC Blockage

Blocked filters, drains or airflow paths cut cooling and can cause leaks.

AC Strange Noises

AC Strange Noises

Rattling, grinding or buzzing points to a loose part, failing fan or bearing.

AC Outside / Outdoor Fan Problem

AC Outside / Outdoor Fan Problem

The outdoor fan does not spin or runs slow, so the unit overheats and cuts cooling.

AC External Unit Problem

AC External Unit Problem

The outdoor condenser unit fails, trips or overheats and needs on-site repair.

AC Thermostat Issues

AC Thermostat Issues

A faulty thermostat misreads temperature, so the AC over- or under-cools.

AC Sensor Problem

AC Sensor Problem

A defective temperature/room sensor makes the AC cycle wrongly or ignore the remote.

AC Remote Not Working

AC Remote Not Working

The remote or the unit's receiver fails, so settings cannot be changed.

AC Faulty Wiring

AC Faulty Wiring

Damaged or loose wiring causes tripping, no-power or intermittent operation.

AC Circuit / PCB Breakage

AC Circuit / PCB Breakage

A burnt or faulty control PCB stops the AC responding correctly.

AC Broken / Physical Damage

AC Broken / Physical Damage

Cracked panels, broken blades or physical damage need part repair or replacement.
