My Reverse Cycle Doesn’t Heat

A reverse cycle air conditioner is a common home air conditioning appliance in Australia. The phrase “reverse cycle” denotes that the AC offers both cooling and heating functions. The refrigeration cycle in the AC is reversible. It’s basically a dual-system setup that’s usable throughout the year.

But what if the AC doesn’t produce heat after its heating mode is switched on? The following are the possible reasons why this could be the case and what you could do about them. 

Gas Could Be Lacking

Your air conditioner needs gas to release hot or cool air. If the gas is lacking, it may not work as advertised. To confirm lack of gas is truly the cause, inspect your AC’s external unit and check whether there is any freezing or frosting. When there’s enough gas, frosting or freezing won’t happen. At times, the unit may have necessary gas, but certain things could be hindering its flow. For instance, the external fan may not be working and that could be freezing the unit. 

Dirty Internal Unit Filters

Dirty filters could cause the AC to not release warm air optimally. Also, the air output would be reduced, which would further add to the AC’s inability to completely heat your room. This would also raise the external unit’s gas pressure. Your machine’s electric consumption would also go up, as a result. If it’s hard to access the filters of your AC, at least make sure enough hot air passes through. 

Dirty Fan or Heat Exchanger

Like the dirty filters, the internal unit’s fan or heat exchanger could be replete with dirt and the reason behind the reverse cycle air conditioner’s heating problem. If that’s the case, the unit will not function properly. The symptoms of this are almost identical to signs of a dirty filter. The unit would be throwing hot air; however, the air would be quite soft. 

Compressor Not Working

If your AC unit’s compressor isn’t working, hot air release could become a major challenge. This problem could be due to a fault in the compressor, electronics board, or condenser. In such cases, it’s better to contact the experts so that you could clearly ascertain the fault’s origin. 

Air conditioning systems are major electrical appliances in any house or office. Therefore, except for cleaning the dirty filters, you shouldn’t be taking matters in your own hands or repairing AC by yourself.
