You should know the basics on troubleshooting your air conditioner/heat pump even if you regularly maintain your unit. Knowledge of troubleshooting saves time, money and further inconvenience. Follow these tips for the proper ways of troubleshooting your air conditioner/heat pump combo.
Reading the Manual
First you need to familiarize yourself with the manual that came with your unit. Read through the maintenance and troubleshooting portion aside from the installation section, so that you know what proper things to do when you encounter problems. The maintenance section will give you ideas on how to take care of your air conditioner/heat pump. The troubleshooting portion will guide you through the step-by-step actions you need to perform when you encounter problems.
Be alert to the noise your unit emits. You can hear a “shuh” sound after turning on your unit. You can hear a “pshh pshh” sound when your air conditioner/heat pump is still in operation or immediately after it shuts down. A clicking sound is caused by plastic parts expanding or shrinking due to temperature change. Meanwhile, when you hear a noise like running water, keep in mind that this is caused by refrigerant liquid that is circulating in your air conditioner/heat pump.
Addressing Cooling and Heating Problems
If the temperature distribution is not working properly, the most common reason is that you started the air conditioning while it was very hot outside or the heat when it was very cold outside. When your unit experiences cooling or heating problems, program the right temperature once your unit is adjusted to the room temperature.
Evaluating Bad Smells
If your room smells different after you turn on the heat or the air conditioning, check on your exhaust pipes and connection. The smell is most likely coming from old pipes or dirty exhaust. Check that the smell is not the result of humidity in the wall, carpets, furniture or other fabrics in the room.
Observing Excess Water
Remember that it is normal to see water running out of your air conditioner/heat pump combo. When the unit cools air in the room, it produces water. Excess water is not normal for units that are only heating pumps.
Addressing Operation Failure
If your air conditioner/heat pump fails to run, make sure to check if you plugged the switch into the socket. Check that the fuse has not blown or the main breaker has not tripped. If your unit still refuses to switch on, make sure that you use the correct programming function, meaning that you did not accidentally switch the remote off while trying to adjust the temperature.
Calling about Service and Warranty
You should contact your unit’s salesman and inquire about service options and warranty coverage if your problem still persists.
