Air conditioning makes each Amarillo summer more bearable, but what happens when your A/C is blowing hot air instead of cold? Routine maintenance can prevent most issues before they arise, but address any that do right away. Here is a list of some common reasons your system may be malfunctioning and what to do to keep your cool.
Possible Reasons Your A/C Is Blowing Hot Air
- A/C settings: Rule out human error first. The selector switch may be on “heat” rather than “cool”. If so, the A/C will blow warm air. Switching it back to “cool” will set things right.
- The compressor and condenser: Head outside to the outdoor component of your A/C that houses the condenser and compressor and check to see that there is power to the unit. Without it, the indoor system will continue to run, but not cool your home. Check for any airflow obstructions and clear them. See if the condenser coils are hampered by dirt or debris; coils may require cleaning throughout cooling season.
- A dirty air filter: A clogged filter can cause evaporator coils to freeze, which prevents proper cooling. Change the air filter as needed during peak cooling season.
- Refrigerant issues: A leak or compressor issue can result in a loss of refrigerant and a reduced charge or ice formation on the exterior and/or interior coils. All need to be addressed by a professional.
