Aircon Repair
Aircon repair, for some essential components of the air conditioning unit, can be synonymous to parts replacement because certain AC parts, once damaged, are more cost-effective to simply replace with a working one than to repair. Examples of the latter include a malfunctioning compressor and PCBs–which are normally replaced with a complete circuit box containing an entire set of PCBs.
An air conditioning unit comes with its own self-diagnostic and troubleshooting procedures. These are called error codes, which are specific to an AC brand and model. They correspond to defects identified by the system, and each error code will have its corresponding troubleshooting procedure. Error codes are normally shown as alphanumeric codes on the AC timer display or as blinks on an indicator light. Meanwhile, here’s a generalized and simplified rundown of common aircon problems as well as their corresponding repair methods and strategies:
Aircon Repair: Thermistor
Thermistors (or temperature sensors) are present in both the indoor and outdoor units of a split-type air conditioner. Common thermistor issues involve corroded sensor heads and wiring damage, both of which entail replacement with a functional one.
Aircon Repair: PCB
Like thermistors, circuit boards–which regulate, control, and transmit signals to different motors and interrelated AC parts–are present in both indoor and outdoor units of a centralized air conditioning system. Dirt accumulation, burnt terminals, electrical circuit problems, and loose or damaged wiring are the most common causes of PCB-related faults. Repairing them, depending on the cause of the problem, normally requires a service technician to do a series of elimination test runs to identify which circuit has a defect.
Aircon Repair: Fan Motor
The aircon fan motor, and because it is a motor, is subject to mechanical wear and tear. An overworked fan motor can be caused by a dirty, ill-maintained air conditioning unit. It can also be a result of a power supply problem. In either case, an HVAC technician will determine whether or not repairing a damaged fan motor or replacing it with a new one is merited.
Aircon Repair: Refrigerant Circuit
The refrigerant circuit of the aircon can suffer from two common issues: a leak in the chiller pipes (which you can instantly detect from the ether-like odor of the coolant gas) or a need for a refrigerant gas top-up service. In both cases, seek professional help since aircon refrigerant-related problems are not issues that come readily with DIY fixes.
Aircon Repair: Condensate Drainage Line
Drainage line maintenance tasks, including cleaning of air filters, can be DIY-ed. If you have time, it is recommended that you clean the air filters, empty the drain pan, and run a pressurized air nozzle through the PVC drainage hose to remove moldy gunks and blockages. Otherwise, you can always call in a service professional to devote time to a productive aircon overhaul that will do more than just service the condensate drainage line.
Aircon Repair: Compressor
If there are weird noises coming out of the outdoor sub-unit of your air conditioning system, the AC is struggling to cool the room, the compressor has difficulties with restarting, or a frequent on-off cycling keeps happening, then you might want to check promptly if you have a developing problem with the compressor–the most expensive component of the air conditioner. If the AC is nearing its typical ten to fifteen-year lifespan and the compressor is already showing defects, a service professional is most likely to suggest investing on a new AC unit instead of spending fruitlessly to repair the compressor.
Frequently Asked Questions (FAQs) – Aircon Repair
If you notice any of the following issues, it’s time to call for professional aircon repair services:
- Weak or no airflow from the unit.
- Unusual noises (e.g., grinding, squealing, or rattling).
- Strange odors coming from the aircon.
- Water leakage or excessive condensation.
- The aircon is not cooling effectively.
- Frequent on-and-off cycling.
- A sudden increase in electricity bills.
It’s recommended to service your aircon at least every 3 to 6 months to ensure optimal performance and prevent costly repairs. Regular maintenance can also extend the lifespan of your unit. If you notice any issues, don’t wait—schedule a repair immediately.

While some minor maintenance tasks (like cleaning filters) can be done by homeowners, most aircon repairs require professional expertise. Attempting DIY repairs can lead to further damage, void your warranty, or even pose safety risks. It’s always best to rely on certified technicians.
Water leakage is a common issue caused by clogged drain pipes, dirty filters, or low refrigerant levels. Turn off the unit immediately to prevent further damage and contact our team for a thorough inspection and repair.
Poor cooling performance can be due to dirty or clogged filters, low refrigerant levels, faulty compressors or fans, thermostat issues, and blocked airflow. Our technicians will diagnose the root cause and restore your aircon’s cooling efficiency.
Yes, we offer a warranty on all our repair services and replacement parts. The warranty period may vary depending on the type of repair and parts used. We’ll provide full details of the warranty after completing the repair.
To avoid frequent repairs:
- Schedule regular maintenance every 3-6 months.
- Clean or replace filters monthly.
- Ensure proper airflow around the unit.
- Avoid overworking the aircon by setting a reasonable temperature.
- Address minor issues promptly before they escalate.
Yes, our technicians are experienced in repairing aircons from all major brands, including Daikin, Midea, Mitsubishi, Panasonic, LG, Toshiba, Europace, and more. No matter the brand, we have the expertise to fix it.
Unusual noises often indicate a mechanical issue, such as a loose part, worn-out fan motor, or debris in the unit. Turn off the aircon and contact us immediately to prevent further damage.
If your aircon is more than 10 years old and requires frequent repairs, it may be more cost-effective to replace it with a newer, energy-efficient model. FixFirst technicians can assess your unit and provide recommendations based on its condition and repair costs.
