Imagine driving from work in hot, sweltering day and all you want to do is to reach home and relax under the pleasant air-conditioned environment. But what happens when you arrive at home and find that the AC itself is blowing hot air. Therefore, one shouldn’t wait for summer to arrive to find their AC working opposite to how its supposed to and understand the reasons behind the malfunction.
When an AC blows hot air instead of pleasant cool air, there are several reasons that contribute to it;
Error in Thermostat Settings
Not every time your AC begins to blow hot air means there’s something serious and you need to get it checked it by a professional. Sometimes, a slight, common and obvious blunder such as the thermostat being set at heat mode can cause this issue and a simple reversal to the cool mode and setting the fan from on to auto can fix the issue instantly for you.
Inadequate Cleaning Conditions
Sometimes, the issue may be slightly less obvious than incorrect thermostat setting and the air condition may blow hot air due to dirty conditions. Sometimes, the dirty air filter can cause the evaporator coil to be spoiled that causes the hot air. Perhaps, dirt and dust can also accumulate and block the flow of cold air. You can change the filter by yourself and may even require a professional to change it for you.
Another culprit that leads to the AC blowing hot air can be a leaky refrigerant. However, this is one issue that cannot be fixed by oneself and needs a professional air conditioning repair.
At few instances, breakdown of power to the outside unit and checking the circuit breaker can be beneficial. However, if this electrical issue persists and you need to perpetually check the circuit, it is important to get immediate professional help.
