Reasons Why Your Air Conditioner Is Blowing Hot Air

There is nothing worse than realising your air conditioner is blowing warm air in the middle of the night during hot summer months. So, why is your air conditioner blowing hot air? Well, there are several reasons. In this article, we have shared some of the most common causes as suggested by HVAC technicians who are specialised in air conditioning repairs in Sydney:-

The Thermostat Is Set Incorrectly

It may sound silly. But, it happens. Check your thermostat and ensure it is set at the right temperature to cool your room. Maybe your kids have set it to heat. Besides, the fan will blow when the air conditioner is not actually cooling if you have set your thermostat to ‘auto’ or ‘on’. This makes your cooling unit to blow warm air through the vents when the outdoor unit is not running.

Dirty Evaporator Coil

When was the last time you have cleaned the filters in your cooling unit? If your thermostat is set to cool and you are still getting warm air, the dirty evaporator coil of the filter might be the reason. Yes, dirty air filter and evaporator coil can prevent your AC from properly cooling your room. Filters should be cleaned regularly, and you can do it on your own. You can even change the filter, but you need a professional. This is why it is essential to schedule air conditioning service Sydney at least every six months.

Poorly Maintained Outdoor Unit

Have you ever walked out and looked at the condition of your outdoor unit? Many homeowners don’t care about their air conditioner’s outdoor unit. If the outdoor unit is with dirt and debris or the condenser coil airflow is blocked, the indoor unit won’t function properly. It significantly impacts the air conditioner’s cooling ability. Cleaning the condenser coils is essential and should be made regularly.

The Outdoor Unit Is Not Getting Electricity

Although the indoor unit blows air inside your room, it can cool the room only if the outdoor unit is functioning properly. If the unit is not getting electricity, air will be blowing out of your vents, but it will not be cold. Maybe the fuse has been blown on the circuit or breaker has tripped. Check your circuit breaker and ensure it is supplying electricity to the outdoor unit.
