Nothing can be more petrifying than an air conditioning failure during summers and particularly in La Habra where the sun shines with all its fury. Whether it’s your commercial AC system or household cooling, there are some common reasons of air conditioner failure. Having prior knowledge of the matter at hand can help you in preventing those faults for the comfortable summer season.

Failure of Fuse

In summers when the electrical system is overburdened by a load of different appliances, it is very likely that the high-pressure limit switch of the circuit breaker gets tripped. If the circuit breaker is not reverting back to its normal operations with simple flips, it is advised not to try to adjust it on your own and call a professional electrician or an AC technician.

Leakage of Refrigerant

Failure of air conditioning in case of refrigerant leakage occurs in a gradual manner. Your air conditioning will take a longer time to get to the desired temperature. If you notice a continuing decrease in the cooling capacity of your air conditioning unit, it’s time to call professional inspection for refrigerant leakage. With inadequate levels of refrigerant, you will have to pay extra in utility bills. Furthermore, leakage of refrigerant is also not good for the environment.

So, it is important to take care of this air conditioning issue as soon as possible.

Frozen Evaporating Coils

Air conditioning failure can also occur due to the frozen coil of the evaporator unit. It happens due to the backflow of cool air into the unit due to dirty, clogged air filters or ducts. Frozen coils can’t efficiently carry out the refrigeration cycle, which means the air conditioning unit can’t perform its usual work and it ultimately leads to its complete failure.

If you are replacing the air filters on time and taking care of the sanitation of the ductwork, you won’t encounter the problem of frozen evaporating coils.

Damaged Condenser Unit

Condenser unit is as essential as the evaporator unit for regular running of an air conditioning system. Therefore, any fault in it can also lead to the failure of air conditioner. For instance, damaged fan blades, a buildup of debris inside the unit (since it is placed outside) can result in the failure of the entire air conditioning system.

Condensation is one of the key steps of the refrigeration cycle. If the unit fails to condense the refrigerant back to its liquid form, the refrigeration cycle can’t be completed, resulting in the breakdown of the air conditioner.

Out of Order Thermostat

If your air conditioning is not working according to the set temperature, there is another thing that you might look into i.e. thermostat. A faulty thermostat can greatly affect the cooling ability of your air conditioning. If you are using a worn out mechanical thermostat, we advise you to replace it with a programmable thermostat to have efficient cooling throughout the summer.
