August in the Palm Beaches and the Treasure Coast means high heat and humidity that put your air conditioning system to the test. If your AC—or heat pump—isn’t performing at its best, you may already feel the difference in comfort around your home. At Mechanical Air Conditioning, we specialize in diagnosis and AC repair to fix issues before they turn into costly breakdowns. If your system seems to be struggling, here are some of the most common repair issues to watch out for.
Low Refrigerant Levels
Refrigerant is the lifeblood of your air conditioning system. If your unit has a leak, refrigerant levels drop, and the system can no longer absorb heat effectively. Symptoms include warm air blowing from vents, ice buildup on coils, and higher energy bills. A professional technician can locate the leak, repair it, and recharge your system to restore cooling power.
Dirty or Frozen Evaporator Coils
When airflow is restricted by clogged filters or dirty coils, your AC may freeze up. Frozen coils prevent the system from cooling your home and can even cause water leaks when the ice melts. If you notice poor airflow or visible ice on the unit, it’s time to call for repair. Routine maintenance is the best way to prevent this problem, but if it happens, a technician can quickly resolve it.
Faulty Thermostat
Sometimes the problem isn’t with the AC system itself but with the thermostat. If your thermostat is malfunctioning or out of calibration, it may not signal the system correctly, leading to inconsistent temperatures or a unit that won’t turn on. Upgrading to a programmable or smart thermostat can provide better accuracy, efficiency, and control.
Electrical Issues
Faulty wiring, blown fuses, or failing capacitors are common issues that can prevent your AC from running properly. Electrical problems often reveal themselves through frequent system shutdowns, unresponsive controls, or strange clicking and buzzing sounds. Since electrical components can be dangerous to handle, these repairs should always be left to trained professionals.
Clogged Condensate Drain
Your AC doesn’t just cool the air—it also removes humidity. The moisture collected from the air drains away through a condensate line. If this line becomes clogged, water can back up and cause leaks, water damage, or mold growth. Clearing the drain and ensuring proper drainage is a simple but important repair that keeps your system running smoothly.
Fan Problems
The fans in your AC unit are essential for moving air through the system and expelling heat outdoors. When motors fail, belts wear out, or blades get bent, the result is reduced cooling capacity and potential overheating of the compressor. If you hear loud rattling or notice weak airflow, a fan repair may be necessary.
Why Timely Repairs Matter
Even minor AC issues can escalate quickly if ignored. A struggling system works harder, which means higher energy bills and more wear on critical components. Scheduling prompt repairs not only restores comfort but also protects your system from further damage and extends its lifespan.
