Living in Central Florida, where temperatures soar, the last thing you need is an air conditioner that blows warm air instead of cooling your home. Whether you’re in Kissimmee, St. Cloud, Winter Haven, Haines City, Lakeland, or Davenport, a malfunctioning AC can turn your home into an oven. Before you panic, let’s explore why your AC might be blowing warm air and how to fix it.
Common Reasons Your AC Is Blowing Warm Air
1. Incorrect Thermostat Settings
A surprisingly simple but often overlooked issue is your thermostat settings. If your thermostat is set to “heat” instead of “cool” or if the fan is running continuously, it could cause warm air to blow.
Fix:
- Set your thermostat to ‘cool’ mode.
- Switch the fan setting to ‘auto’, so it only runs when cooling.
- Lower the temperature a few degrees to test if the AC starts cooling.
2. Dirty or Clogged Air Filters
A dirty air filter can restrict airflow, making it harder for your AC to circulate cool air. This can cause the unit to overheat and blow warm air.
Fix:
- Check your air filter and replace it if it’s dirty.
- Change the filter every 1-3 months, especially in hot climates like Kissimmee and Lakeland.
3. Refrigerant Leaks
Refrigerant is crucial for cooling. If your AC is low on refrigerant due to a leak, it won’t cool properly.
Signs of a refrigerant leak:
- Hissing or bubbling noises
- Ice buildup on the AC unit
- Increased energy bills
Fix:
- Call a professional HVAC technician from Freedom Air Conditioning to inspect and repair the leak.
- Regular AC maintenance can help prevent refrigerant issues.
4. Electrical Issues or Power Problems
A tripped breaker or blown fuse can cause the outside AC unit to stop working while the indoor fan continues to blow warm air.
Fix:
- Check your electrical panel for a tripped circuit breaker.
- Reset the breaker and see if the AC starts cooling.
- If it trips again, contact Freedom Air Conditioning to diagnose the issue.
5. Dirty or Blocked Condenser Coils
The outdoor condenser unit needs to release heat efficiently. If it’s dirty or blocked by debris, the system may overheat and fail to cool your home.
Fix:
- Turn off the AC and clear away leaves, dirt, or debris around the outdoor unit.
- Use a hose to gently clean the condenser coils.
- Schedule professional cleaning if the coils are extremely dirty.
6. Faulty Compressor
The compressor is the heart of your AC system. If it fails, the unit won’t be able to circulate refrigerant, leading to warm air.
Fix:
- If you suspect a compressor failure, it’s best to call an HVAC professional.
- A failing compressor may need repair or replacement.
7. Leaky or Disconnected Ductwork
If there are leaks or gaps in your ductwork, the cool air could be escaping into the attic or walls instead of cooling your home.
Fix:
- Check for visible gaps or holes in your ductwork.
- Have a professional perform a duct inspection and sealing service.
8. Frozen Evaporator Coils
If the evaporator coils inside your air handler freeze, they won’t be able to absorb heat, causing warm air to blow.
Fix:
- Turn off the AC and let the coils thaw.
- Check for clogged filters or refrigerant leaks that may be causing the issue.
- If the problem persists, schedule AC repair service in Winter Haven or Davenport.
9. Aging or Inefficient AC System
If your AC is 10-15 years old, it may be struggling to keep up with cooling demands, especially in humid Florida climates.
Fix:
- If your AC is frequently breaking down, consider an upgrade to a high-efficiency unit like the Daikin Fit System.
- Schedule a free consultation with Freedom Air Conditioning to explore energy-efficient options.
