AC problems we fix
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
Cooling is noticeably slower than usual and the AC struggles to hold the set temperature.
AC Not Functional
The system trips, restarts or shuts off on its own and will not run a full cycle.
AC Failed Compressor
The compressor hums, trips or stays silent — the heart of the AC needs diagnosis or replacement.
AC Gas Leakage
Refrigerant leaks starve the coil, so cooling drops off and the unit runs non-stop.
AC Water Leakage
Water drips from the indoor unit — usually a blocked drain, iced coil or tilt problem.
AC Ice Formation
Ice builds up on the coil or pipes, choking airflow and cooling.
AC Coil Problem
A dirty, corroded or damaged evaporator/condenser coil kills efficiency and cooling.
AC Blockage
Blocked filters, drains or airflow paths cut cooling and can cause leaks.
AC Strange Noises
Rattling, grinding or buzzing points to a loose part, failing fan or bearing.
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
The outdoor condenser unit fails, trips or overheats and needs on-site repair.
AC Thermostat Issues
A faulty thermostat misreads temperature, so the AC over- or under-cools.
AC Sensor Problem
A defective temperature/room sensor makes the AC cycle wrongly or ignore the remote.
AC Faulty Wiring
Damaged or loose wiring causes tripping, no-power or intermittent operation.
AC Circuit / PCB Breakage
A burnt or faulty control PCB stops the AC responding correctly.
AC Broken / Physical Damage
Cracked panels, broken blades or physical damage need part repair or replacement.
