AC Not Cooling? 7 Common Problems Only a Licensed HVAC Contractor Can Fix
In the Broward County, FL, to turn off when you needed your air conditioner to cool, is not just an inconvenience, it is an emergency. Having a humid climate and a lot of heat, the faulty work of an AC system can easily turn your house into an unpleasant and dangerous place. Many homeowners try quick DIY fixes, but most cooling issues require the expertise of a licensed HVAC contractor to prevent costly damage.
If your AC is running but not cooling properly, here are seven common problems that only a professional HVAC contractor like Premier Cooling LLC can accurately diagnose and fix.
1. Small Refrigerant Leaks or Two Little Refrigerant Levels.
Low refrigerant is still one of the major causes as to why an AC is not cooling. Refrigerant is necessary to absorb heat in your house. In cases where there is low levels, your system cannot cool.
Refrigerant leakages are frequent in Florida because of the coil aging, and corrosion by humidity. Handling refrigerant is federally regulated, and only a licensed HVAC contractor can safely locate leaks, repair them, and recharge the system.
The reason why DIY fails: When it comes to refrigerant problems, simply filling up the gas will not work, and the leakage would need to be shut professionally.
2. Frozen Evaporator Coils
Frozen evaporator coils may be the trouble maker in case your AC is blowing hot air or poor airflow. The issue is usually caused by a limited airflow, contaminated coils and lack of refrigerant balance.
A licensed HVAC contractor will:
- Identify airflow restrictions
- Clean coils professionally
- Restore proper system pressure
Ignoring frozen coils can lead to compressor failure, one of the costliest AC repairs.
3. Faulty Compressor
The compressor is the heart of your air conditioning system. When it fails, the AC may run but won’t cool your home. Compressor issues are especially common in older systems exposed to Broward County’s extreme summer heat.
Only an experienced HVAC contractor can:
- Test compressor electrical components
- Determine repair vs replacement
- Ensure safe operation
Attempting DIY repairs on a compressor can be dangerous and void warranties.
4. Electrical or Capacitor Failures
Electrical components like capacitors, contactors, and relays help your AC start and run efficiently. Power surges, lightning, and wear-and-tear can cause these parts to fail.
Signs include:
- AC turning on and off randomly
- Outdoor unit not starting
- Warm air blowing from vents
A licensed HVAC contractor ensures proper electrical testing and safe replacement, preventing further system damage.
5. Contaminated or Corrupted Condenser Coils.
The coils of condenser put heat out of doors. Broward County is one of the counties where such coils become filled with dirt, saline air deposits, and debris.
Coils that are dirty decrease efficiency, drive your system more, and cost more money. Professional coil cleaning by an HVAC contractor restores cooling performance and prevents overheating.
6. Leaks in ductwork or Low air-flow.
Leakage or damaged ductwork has been a veiled cause as to why many AC systems do not cool efficiently. Leakages of ducts in Florida homes can use as much as 30 percent of the cooled air.
A licensed HVAC contractor can:
- Inspect ducts using specialized tools
- Seal leaks professionally
- Improve airflow and indoor comfort
This is especially important for older homes in Broward County.
7. Incorrect Thermostat or Control Issues
Sometimes the issue isn’t the AC unit—it’s the thermostat. Faulty sensors, incorrect calibration, or wiring issues can cause your system to cool unevenly or not at all.
An HVAC contractor can:
- Recalibrate or replace thermostats
- Install smart thermostats
- Ensure proper system communication
Proper thermostat setup is crucial for energy efficiency in Florida’s climate.
