Why is my A/C blowing hot air?

Dirt A/C Unit

Now that it’s summertime and the weather’s hot, the last thing you want is warm air blowing from your A/C unit. But what exactly is causing this inconvenience?

There are many different variables that may result in warm air blowing out of your A/C unit, but have no fear. We will discuss the most common causes, including easy ways to troubleshoot on your own before calling a professional.

Easy Troubleshooting

Check that thermostat

Make sure your thermostat is set to “COOL” and your fan is set to “AUTO,” rather than “ON.” It is recommended that your temperature setting be at least five degrees below what the room temperature reads on your thermostat.

Clean filter, cool air

Is your air filter dirty? A clean air filter is very important in protecting the inside of your A/C unit from dirt and dust that can block proper airflow. Check your air filter and change it accordingly. We recommend checking your air filter for debris once a month. 

Remove any debris

Your A/C unit is made up of two main parts, an outdoor unit and an indoor unit. Have you checked your outside unit lately? Identify and remove any blockage such as dirt, grass or leaves. Any debris such as these can interfere with your system’s working parts.

More Complex Issues

If you have completed this initial troubleshooting and your air conditioning is still blowing hot air, there may be a more complex issue at hand.

Pesky leaks

A leaky air duct may be messing with the cooling process. Are your ducts tucked away in your walls, attic or basement? Contact a professional for help.

Low refrigerant

Refrigerant is the substance in your unit responsible for absorbing heat from the outside and turning it into cool air for your house inside.

Your system may be losing its cool as a result of low refrigerant levels. You will need a professional to identify if this is the problem.

Tripped breaker or blown fuse

If hot air is blowing out of your vents, the fuse may have blown on the electrical circuit that provides electricity to your outdoor unit or the circuit breaker may have been tripped.

Check your fuse panel or circuit breaker to make sure the circuit is supplying electricity to the outside air conditioning unit.

If the circuit breaker was tripped or a fuse was blown, call a professional as there may be a major problem.
