Air Conditioning Troubleshooting Guide

1. Why is my system not heating or cooling?

Firstly, check the operation MODE on your controller. Regardless of the temperature you set it at, it needs to be set to HEAT mode to warm your home, and COOL for it to cool it down. Read your user manual or ask your technician to demonstrate the di erent modes and functions on the control as every mode button can look different.

2. Why is my system sometimes louder than normal?

2. Why is my system sometimes louder than normal?

If you have an inverter system, you will find the outdoor unit will sometimes be louder than other
times. This is normal. When the outside air temperature is very cold or very hot, the system needs to work harder to absorb or reject the heat from its surroundings. This means the compressor and the fan motors must run faster, which increases the overall sound levels coming from the outdoor unit.

3. My system is leaking water/steam from the outdoor unit. What should I do? Is this normal?

During normal operation in heating mode, the outdoor unit produces condensation. If you don’t have a drain installed on your outdoor unit, condensation may leak from the bottom of the unit, which is the water you may see.

4. Why is my system not heating/cooling as well as it used to?

4. Why is my system not heating/cooling as well as it used to?

Throughout the working life of your system, it moves a lot of air around. This air carries dust and other airborne contaminants. Over time, these particles accumulate in your system, affecting the efficiency of the system and its heating and cooling capabilities. When was the last time you had your A/C system maintained? Your filters are probably in need of cleaning or replacing.

5. Why does my system stop blowing hot air in heating?

When your system is in heating mode, it needs to periodically defrost the outdoor unit,
particularly when it is very cold. When this happens, the indoor unit stops blowing hot air. This usually only takes a few minutes, in which the system then returns to normal
operation.

6. My system is showing an ERROR code on the controller. What should I do?

6. My system is showing an ERROR code on the controller. What should I do?

If you see an error code, this indicates there is a problem. Some errors can be due to power fluctuation and can be cleared by resetting the A/C. You can reset it by turning OFF the power supply (isolator switch located next to the condenser) for five minutes. Then switch is back ON. If the fault reoccurs, make a note of the code, and call your Alliance Care team.

7. Why is my system filter/service indicator showing when I only recently cleaned the filter?

The filter indicator is not a direct measure of how blocked the filter is. It is a timed indicator, activated after a pre-set number of running hours. You can easily reset it, simply check in your user manual, or speak to your Alliance service technician.

8. I have changed internet provider and now I can’t control my system from phone. How do I fix this?

If you have recently changed your Wi-Fi router or network provider, you may need to re-connect your system to your Wi-Fi network. Using the app on your phone, start the re-pairing procedure. The app will take you through the process step-by-step.
