Every homeowner with an air conditioner (AC) should know when an AC problem requires a technician's input. Here are some of the cases in which you should call a technician.
The AC Keeps Tripping the Breaker
If the AC keeps tripping the breaker, it means the AC has an electrical problem. Maybe there is a problem with the motor or the electrical connections to the AC. In any case, you should not reset the breaker every time the AC trips it. Once you have confirmed that the AC is the culprit, switch off the AC, leave the breaker in its tripped condition, and call an AC technician. Electrical problems are dangerous (there is a risk of damage and injury) and the electrical problem may cause further damage if you continue forcing the AC to run.
The AC Has an Electrical Problem
Electrical problems, even if you know what they are, usually call for the involvement of a professional technician. Potential electrical problems with the AC include damaged start capacitors (that powers the AC during startup), seized AC motors, and damaged circuit boards, among others. Unless you have some electrical experience, you risk causing more damage than solutions if you try DIY electrical repairs on your AC.
The AC Is Leaking Refrigerant
The refrigerant is responsible for absorbing heat inside your house and dumping it outside. Thus, inefficient cooling is the first thing that you will notice if the refrigerant is low due to a leak. This is because the inadequate refrigerant won't be able to absorb as much of the heat in the house. Apart from inefficient cooling, the risk of AC damage also rises if the refrigerant level falls too low. The AC will overwork if the refrigerant level falls, and an overworked AC is prone to breakdowns.
The refrigerant is also a poisonous chemical that you shouldn't breathe in. If the refrigerant is leaking, then it's likely polluting your indoor air and possibly making you sick. In addition, the refrigerant also pollutes the environment at large since it depletes the protective ozone layer that envelops the planet. Considering all these issues, you ought to call an AC technician the minute you suspect the AC's refrigerant is leaking.
You are Clueless about ACs
Lastly, you should call an AC technician any time you suspect an AC malfunction and you have no idea about AC operations. Maybe the AC can't start or isn't cooling even though it is connected to power, there is power, and you have set the correct temperature. If you are honest with your ignorance about AC operations, don't waste time and risk your AC—call a technician immediately.
