Are you sitting at your home, trying to be comfortable and suddenly realize that your AC unit is blowing hot air instead of cooling your home? Yes, that could happen and it might be really uncomfortable, especially during the hot summer days.
But don’t worry. We have couple of common reasons why your AC unit might be blowing hot air and we will help you find out what is the case.
Thermostat Settings
Yes, it might sound funny, but sometimes having your thermostat on a wrong fan setting might be the cause of your AC blowing hot air. Check to make sure it is not set to “heat” mode, or if it is set to “on”, then it means that the fan will stay on even when the air conditioner is not cooling your home. In this case, just change it to “auto” to have it automatically turn on and off to keep your home cool.
Dirty Coils or Dirty Air Filters
Having a dirty air filter will result in dirty evaporator coils. This will result keeping your air conditioner from normally cooling your home. Make sure you always clean and replace your air filters regularly to prevent these types of issues. If it is too late and the coils are filled with dirt, have a HVAC professional to take the necessary actions to clean the coils and replace the air filters for your HVAC system to start working efficiently.
Issues with Outside Unit
Go outside and make sure your outdoor unit is not clogged with dirt, leaves or any other objects. Outdoor unit of your HVAC system has condenser coils, which need clean and unrestricted airflow to be able to work properly and remove heat from your home. Take the necessary actions to always have a well maintained HVAC system to not come across with issues like this.
As long as your outside, also make sure the outdoor unit has not lost power. Sometimes, the outdoor unit loses a power, while the indoor unit keeps operating. This might happen because of a tripped breaker of the outdoor unit. Reset the breaker and if it keeps happening, then make sure to contact a professional to find out what is happening with the system.
Low Refrigerant
Sometimes the reason for your AC unit blowing hot air might be because your unit is low on refrigerant. Refrigerant is responsible for absorbing the heat from the air. It is a heat transfer liquid. Because of having refrigerant leaks, your AC unit could start operating not properly. In this case you will need a HVAC professional to determine whether that’s the case and take the necessary actions like finding the leak, repairing if possible and adding refrigerant.
