It can be absolutely frustrating to find yourself in the middle of a hot summer day with no cooling at all because your ductless unit has stopped working. And even worse is that, at this time, it is almost impossible for you to find a reliable service which could respond instantly. As a result, the only alternative is to spend a few days in discomfort or use other cooling means; fans, although you know well when it gets extremely hot, fans are not the answer. But why keep waiting for an HVAC saviour and why not do what you can do to fix the problem? It is true that many HVAC professionals strictly abstain homeowners from trying DIY solutions with their HVAC appliances but it is also true that sometimes the issues are so petty that they do not need a technician's help in the first place. For example, if your Split Air Conditioner doesn't turn on and the reason is that the switch is not properly plugged in, do you need a technician to do that for you? Of course, not!
So today, we are going to discuss the AC issues which you can easily troubleshoot on your own. Just some confidence!

The power issue. "My AC doesn't turn on!" 

So you pressed the power button on the remote control and the unit did not turn on? Don't panic! Here's are the possible reasons for that;

• Faulty Remote Controller Batteries

- If you are trying to turn the system on using a remote control, the most probable thing is that the batteries on the remote need to be replaced and that it is the remote which needs fixing. Please note to always keep extra batteries at home in order to save yourself from panicking in such situations. Replace the batteries and try again. Turned on? Great! Did not turn on? Move to the next part.

• Improperly plugged power switch

- You know that a ductless system is directly plugged into a power supply. The switch may have been loosened from the plug and thus may not allow the needed power supply. Or, the circuit breaker may have been tripped.
i. Check the power supply. Unplug it and then replug properly. 
ii. Check the circuit breaker. If it is found tripped, do the following;
a. Always turn it off
b. Turn it back on
Please note to never directly turn on the circuit breaker if is it tripped 

• Faulty Thermostat

If you had begun with trying to turn on the system using a Thermostat, try doing it otherwise; use a remote controller. If the unit is turned on using remote but does not turn on through the Thermostat, you know where the problem exists; it is with the thermostat. Once again, consider checking Thermostat batteries if it is a Smart Thermostat. But since this is a problem that does not affect the supply of cool air directly, you can choose to call a professional technician to help you resolve the Thermostat issue later.
