As temperatures rise and the summer heat becomes relentless, the last thing you want is for your air conditioning unit to blow hot air. When faced with this frustrating situation, understanding the potential causes can help you troubleshoot effectively and restore comfort to your home.


The experts at Harrington Air Conditioning share here five common reasons why your unit might be blowing hot air and dive into the critical role that regular maintenance plays in preventing these issues.


Low Refrigerant Levels

One of the primary reasons your AC may be blowing hot air could be low refrigerant levels. But what exactly is refrigerant? Well, it is the substance responsible for absorbing heat from the air in your home and cooling it down. So, as you can imagine, when your refrigerant levels are low, the air cannot be effectively cooled. Regular maintenance checks can detect and address refrigerant leaks before they escalate, ensuring your system remains adequately charged for optimal cooling.


Dirty or Clogged Filters

Clogged or dirty air filters don’t just have a negative impact on your indoor air quality, but they can also restrict airflow to your AC system. When airflow is restricted, the air passing through the system may not have had enough contact with the cold evaporator coils to be adequately cooled. Regularly replacing your filters as part of routine maintenance can help prevent this issue and keep your AC running smoothly.


Blocked Condenser Unit

The condenser unit, located outside your home, plays a crucial role in releasing heat from the refrigerant. If the unit is blocked by debris, it cannot release the heat effectively, causing your AC to blow hot air instead of cold air. Clearing any debris from around the condenser and ensuring proper airflow can help resolve this issue.


Malfunctioning Thermostat

Your thermostat could be the culprit for unpleasant temperatures in your home. Issues such as a misreading temperature sensor or faulty wiring can lead to incorrect temperature settings and improper operation of your AC unit. An expert technician can identify these issues during a maintenance check and either repair your thermostat or replace it.



Faulty Compressor

The compressor is commonly referred to as the heart of your AC system and is responsible for compressing and circulating refrigerant to facilitate the cooling process. If the compressor is malfunctioning or failing, it may struggle to cool the air effectively, resulting in hot air blowing from your vents. Be aware that this is not a project you should take on yourself. Repairing or replacing a faulty compressor is a job best left to an experienced HVAC professional.
