Why Your AC Unit Keeps Turning On and Off — Common Causes Explained Why Your AC Unit Keeps Turning On and Off — Common Causes Explained

Is your air conditioner constantly cycling on and off? This problem, known as “short cycling,” is one of the most common issues homeowners face in Hollywood, FL and across Broward County. Not only does it affect comfort, but it also puts unnecessary stress on your system — driving up your energy bills and repair costs. Let’s look at what’s causing it and how to fix it.

1. Incorrect AC Size

If your air conditioner is too large for your home, it will cool the air too quickly, shut off, then restart minutes later. This frequent cycling wastes energy and wears out parts prematurely. Homeowners in Pembroke Pines and Hallandale Beach can prevent this issue by working with experts who perform proper load calculations before AC installation in Hollywood, FL.

2. Dirty Air Filters

Restricted airflow forces your system to overheat and shut off prematurely to protect itself. Replacing or cleaning filters every 30 to 60 days can eliminate this issue entirely. Routine AC maintenance in Hollywood, FL ensures your filters and coils stay clean for consistent performance.

3. Low Refrigerant Levels

When your system doesn’t have enough refrigerant, pressure inside the unit fluctuates, causing short cycling. This often points to a leak that needs immediate attention. Contact professionals for AC repair in Hallandale Beach, FL to inspect, recharge, and seal your system properly.

4. Electrical or Thermostat Malfunctions

Faulty wiring, failing relays, or a bad thermostat can cause your system to power on and off at random. A certified technician in Miramar can quickly diagnose and repair the problem before it leads to more serious damage.

5. Dirty Condenser Coils

When your outdoor unit is covered in dirt, leaves, or debris, it can’t release heat effectively. This makes the compressor overheat, triggering automatic shutdowns. Schedule seasonal AC maintenance in Pembroke Pines to keep your condenser clean and your system running smoothly.

6. Oversized or Undersized Ductwork

Improperly sized ductwork can also cause pressure imbalances, leading to rapid cycling. A professional inspection during AC installation in Hallandale Beach, FL ensures your ducts match your system’s airflow requirements for steady, efficient cooling.
