Every summer, as the heat and humidity rise in Kendall, air conditioners start breaking down at record levels. Homeowners across South Florida experience the same issue: their AC systems stop cooling at the peak of demand, when comfort matters most. But these breakdowns don’t happen by chance. They stem from a few predictable issues linked to prolonged heat and humidity.
If you understand why these failures happen, you can take simple steps to keep your system running and your home comfortable all season long.
Heat, Dirt, and Neglect: The Perfect Storm
One of the biggest causes of summer AC breakdowns in Kendall is simple neglect. When filters go unchanged or coils stay dirty, the system loses efficiency and airflow.
Here’s what happens behind the scenes:
- Clogged air filters block airflow and make the blower motor work harder.
- Dusty evaporator coils can’t absorb heat, leading to ice buildup.
- Dirty condensers trap heat instead of releasing it.
This cumulative stress compromises system performance. A dirty system can raise your energy bill, reduce cooling power, and push your AC toward an early breakdown.
Replace filters every 30 days during summer and rinse the outdoor unit monthly to prevent debris buildup
Electrical Failures and Power Surges
Another hidden danger during summer is power fluctuation. Sudden summer storms frequently trigger voltage fluctuations and outages. When the power returns, the surge can damage your system’s capacitor, compressor, or circuit board.
If your unit doesn’t turn on after a storm, or if you hear clicking and buzzing, you may have electrical damage.
To protect your system:
- Install a surge protector made for HVAC systems.
- Avoid restarting your AC immediately after a power outage. Wait at least 15 minutes.
- Have an electrician check your circuit if the breaker keeps tripping.
These simple precautions can help you avoid costly electrical repairs.
Refrigerant Leaks and Frozen Coils
Low refrigerant is another major reason for mid-summer breakdowns. When levels drop, pressure inside the coils changes, causing them to freeze. You’ll notice weak airflow or warm air blowing from the vents before the system stops cooling completely.
If you see ice on the lines or hear hissing near the unit, turn it off and call a professional right away. Running it frozen can destroy the compressor.
Certified technicians can locate and seal the leak, then recharge the system to restore optimal cooling. If your unit is older, it might be time to upgrade to a more efficient model that uses eco-friendly refrigerant.
Poor Airflow and Oversized Units
It might sound surprising, but a unit that’s too big for your home can break down faster. Oversized units cool rapidly but fail to complete the dehumidification cycle, leading to discomfort and wear. This constant cycling on and off wears out parts like fans and compressors.
Meanwhile, undersized systems run nonstop and overheat. Both situations lead to breakdowns, higher bills, and shorter equipment life.
A professional load calculation ensures your AC is the right size for your home and Kendall’s weather conditions.
Signs Your AC is Breaking Down
You don’t have to wait for your system to stop working to know something’s wrong. Watch for these early warning signs:
- Airflow feels weak or uneven
- Strange noises (grinding, buzzing, or rattling)
- Musty or burning smells
- Ice forming on lines or coils
- AC turns on and off too often
- Energy bills are rising for no clear reason
When these symptoms appear, your system is already struggling. Prompt service can prevent total system failure and costly repairs.

Don’t Let Your AC Quit on You
Most AC problems in Kendall don’t just happen out of nowhere; they build up over time. When you ignore small issues, they turn into big, expensive ones. You can stop this by doing simple things like changing your filters, cleaning the coils, checking the refrigerant, and getting regular checkups.
If your AC starts acting weak during summer or can’t handle the heat anymore, call a professional right away. Addressing minor issues early extends your AC’s lifespan and ensures consistent comfort, even during Kendall’s peak summer heat.
