In this guide, we break down the most common aircon problems, including Common Aircon Problems, and what you can do to fix them—or know when to call an expert.
One crucial point to consider is whether the air conditioning unit is appropriately sized for your space. An undersized unit may struggle to cool effectively, while an oversized unit may cycle too frequently, leading to inefficiencies. If you find your aircon is consistently unable to cool your space, it may be worthwhile to consult with a professional regarding the appropriate unit size for your needs.
1. Aircon Not Cooling Properly
This is a common issue faced by many air conditioner users. Understanding how your air conditioning system works can help you troubleshoot effectively.
Regular maintenance helps avoid common aircon problems, ensuring your unit runs efficiently.
Possible Causes:
- Dirty air filter
- Low refrigerant gas
- Blocked condenser unit
- Incorrect thermostat settings
Troubleshooting Tips:
Additionally, factors such as insulation and the number of windows in a room can influence how effectively a unit cools the space. For example, rooms with poor insulation may allow cool air to escape, making it harder for your air conditioning system to maintain a comfortable temperature.
- Check and clean the air filter
- Ensure windows and doors are closed
- Set the thermostat to the correct mode (cool)
- If the issue persists, call a technician to check the refrigerant levels
2. Aircon Won’t Turn On
If your unit doesn’t start at all, it could be an electrical issue.
Possible Causes:
- Tripped circuit breaker or plug
- Loose wiring
- Faulty remote
It’s important to regularly check for any obstructions around your air conditioning unit. Items like furniture, curtains, or even dirt can block airflow, reducing the cooling efficiency. Regularly inspecting the external unit can also help keep it free from debris such as leaves or dirt.
Troubleshooting Tips:
- Check the circuit breaker & plug and reset if necessary
- Replace the batteries in the remote
- Ensure the thermostat is set to “cool” and a lower temperature
If there’s still no response, it’s best to call a qualified aircon technician to inspect the system.
3. Water Leaking from the Indoor Unit
Water leaks from the indoor unit can lead to significant water damage and health risks due to mold growth. Understanding the causes can help prevent this issue.
Leaks inside your home can lead to water damage and mold growth.
Possible Causes:
- Clogged drain pipe
- Dirty air filter
- Broken condensate pump
Troubleshooting Tips:
Addressing common aircon problems quickly can prevent further damage and costly repairs.
Many homeowners encounter common aircon problems, such as leaks or unusual noises.
Understanding how common aircon problems develop can help in effective troubleshooting.
- Clean the filter
- Check the drain line for blockages (pouring a cup of vinegar down the pipe can help)
- If leaking continues, contact a professional to clean the drainage system
Regular inspections can help identify common aircon problems before they escalate.
It’s also worth considering the age of your unit. Older models may have more frequent issues with starting and may benefit from replacement with a newer, more efficient model. A professional can help assess whether repairs or replacement are more cost-effective in the long run.
Regularly inspecting the drainage system of your air conditioning unit can help prevent clogs that lead to leaks. Keeping the area around the drain line clear and ensuring that it is functioning properly can mitigate many of these issues.
4. Unusual Noises from the Aircon
Hearing unusual noises can be alarming. While air conditioning units do produce sounds, loud bangs or persistent rattling can indicate significant issues.
All aircons make some noise, but loud bangs, rattles, or buzzing could mean something’s wrong.
When troubleshooting aircon problems, it’s beneficial to keep a record of what has been checked or repaired. This can help identify patterns that may warrant further inspection by a professional.
Possible Causes:
- Loose components
- Debris in the fan
- Failing motor or compressor
Troubleshooting Tips:
Do not attempt internal repairs—call a certified technician
Turn off the unit immediately
5. Bad Smells from the Unit
Foul or musty odours from your aircon can be unpleasant and unhealthy.
Possible Causes:
- Mold or bacteria buildup
- Dirty filters
- Clogged drain line
Troubleshooting Tips:
- Clean or replace air filters
- Run the unit in “fan” mode for a few hours
- Schedule a deep cleaning with an aircon professional
6. High Electricity Bills
High electricity bills can be concerning, especially if you feel you’re using your air conditioning system properly. Identifying the causes can help mitigate this issue.
If your energy bill has gone up significantly, your aircon could be the cause.
Possible Causes:
- Poor efficiency from dirty components
- Old or underperforming unit
- Thermostat set too low for extended periods
Troubleshooting Tips:
- Clean filters and coils
- Use a programmable thermostat
- Consider upgrading to an energy-efficient inverter model
