My AC is Blowing Warm Air. A Troubleshooting Guide for Winter Garden, FL
When your air conditioner in Winter Garden, FL, starts blowing warm air, it signals a major system failure, particularly during Central Florida’s intense heat. This problem is frustrating and demands immediate attention. The issue can be caused by a simple setting error, or it could indicate a severe, underlying problem like a refrigerant leak or compressor failure. This guide will help you troubleshoot the most common causes and determine when to call for professional service.
Simple Checks to Perform Before Calling for HVAC Repair
1. Check Your Thermostat Settings
This is the easiest and most common fix. Ensure your thermostat is set to “COOL” and that the temperature is set lower than the current room temperature. Also, check the fan setting. If the fan is set to “ON” instead of “AUTO,” the blower runs even when the cooling cycle is off, circulating warm air. Switch the fan setting to “AUTO.”
2. Inspect Your HVAC Air Filter
A severely clogged air filter is a major culprit. It restricts airflow across the indoor evaporator coil. This lack of airflow causes the coil to freeze solid, even on a hot day. A frozen coil cannot absorb heat from your home, resulting in warm air from the vents. If the filter is visibly dirty, replace it immediately.
3. Check the Circuit Breaker
Your outdoor condenser unit and indoor air handler each have a dedicated circuit breaker. Check your main electrical panel. If a breaker is tripped, reset it. If the breaker trips again immediately, do not reset it; this signals a dangerous electrical short and requires a professional.
Core Problems: Why the AC Fails to Cool
If the simple checks fail, the problem lies with your HVAC Winter Garden FL system’s ability to transfer heat.
Low Refrigerant Levels
This is the most common major issue. If your system is low on refrigerant, it means you have a leak. Without the correct amount of refrigerant, your system loses its ability to cool effectively, causing it to run constantly and blow warm air. Low refrigerant also leads to the dangerous coil freezing mentioned above.
A Failed HVAC Capacitor or Contactor
The capacitor is a small electrical component that provides the jolt needed to start the compressor and fan motors. If the outdoor unit’s fan or the large compressor motor is not running, the capacitor has likely failed. Without these running, the system cannot shed heat outside, and you will get warm air inside.
Dirty Outdoor Condenser Coils
Your outdoor unit’s large coil releases the heat your system collects. If this coil is covered in dirt, grass clippings, or debris, the grime acts as an insulator. The unit cannot shed the heat, which causes the system to overheat and shut down prematurely, leaving you with poor cooling.
Why You Need Professional HVAC Winter Garden FL Service
The Danger of Ignoring the Issue
Running an AC unit that is low on refrigerant or has a bad capacitor will destroy the much more expensive compressor, the heart of the system. Ignoring the problem turns a minor AC Repair into a catastrophic system replacement. Furthermore, only a licensed professional can legally handle and add refrigerant.
