Why Is My AC Blowing Out Warm Air?

When the temperature rises – and air conditioners are pushed to their limits – they are more likely to break down and require maintenance. An AC that is spewing warm air is one AC repair issue several homes encounter.

AC Blowing Warm Air: What’s Wrong?

Some of the most common reasons ACs blow warm air are:

  • Thermostat settings errors

  • Outside Unit Has Lost Power

  • Refrigerant leak

Thermostat settings errors

Sometimes, the problem could be something as minor as having the thermostat set wrong. Always be sure to double check that the system is set to cool and that the fan is set on auto as opposed to on. If you’re lucky, this little change could potentially be the answer to your problem.

Outside Unit Has Lost Power

If the outside unit loses power while the indoor unit does not, your A/C system may blast heated air. A tripped circuit breaker or blown fuse could have caused the unit to lose power.The circuit breaker and fuse panel will need to be checked.

Refrigerant Leak

One of the main causes of a malfunctioning air conditioner is low refrigerant. If you have a worn service valve, loose joints, or poor assembly, you could have undercharged or overcharged refrigerant.

Refrigerant (aka coolant) is highly dangerous. Unless you are a qualified technician, you should never try fixing refrigerant problems yourself. The best way to prevent refrigerant leaks in the first place is to schedule annual air conditioning tune-ups before the cooling season begins.
