Why Is My Air Conditioner Running But Not Cooling? (Florida Homeowner Guide)
There’s nothing more frustrating than hearing your air conditioner running while your home continues getting hotter.
In Florida’s heat and humidity, this is one of the most common HVAC service calls.
Dirty Air Filter
A clogged air filter restricts airflow and prevents your system from circulating enough cool air.
Low Refrigerant
Low refrigerant can cause warm air, frozen coils, and poor humidity removal. If refrigerant is low, there may be a leak.
Dirty Outdoor Condenser
Leaves, grass, dirt, and debris can block airflow and prevent the system from releasing heat properly.
Frozen Evaporator Coil
Restricted airflow or low refrigerant can cause the indoor coil to freeze and reduce cooling performance.
Thermostat Problems
Incorrect settings, dead batteries, or faulty sensors can prevent your AC from cooling properly.
Aging Equipment
Older systems can lose efficiency over time, especially in Florida’s hot and humid climate.
When to Call an HVAC Professional
- Your AC blows warm air
- Ice forms on the system
- The breaker keeps tripping
- Water leaks from the indoor unit
- Your home never reaches the thermostat setting
- Your utility bill suddenly increases
