To survive the summer heat, air conditioning systems are necessary. However, like any complex machinery, they can encounter issues. Whether in New Smyrna Beach territory or elsewhere, understanding the most common problems can help you troubleshoot or decide when to call a professional. Frequent maintenance may prolong the lifespan of your equipment and keep it operating at peak performance. Ignoring these issues may result in more severe problems and more costly fixes.

Frozen Evaporator Coils

This issue typically arises when there is restricted airflow or insufficient refrigerant. Frozen coils will hinder the cooling process, possibly causing the system to freeze entirely. Heat is taken from the air via the evaporator coil, which becomes ineffective when it freezes. This can result in inefficiencies and even system failures.

  • Signs: Ice buildup on the outdoor unit, warm air blowing from vents, reduced airflow.
  • Solution: Change the air filter and ensure proper airflow. If problems persist, seek expert help immediately to prevent further damage.

It’s critical to fix frozen evaporator coils immediately to prevent further damage. For expert repair services, New Smyrna Beach air conditioning specialists can quickly diagnose and resolve the problem, ensuring your system runs smoothly again.

Refrigerant Leaks

Low refrigerant levels usually point to a leak or an undercharged unit. This issue can significantly affect the efficiency and lifespan of your air conditioning system. Refrigerant is crucial for absorbing heat and cooling the air circulating through your home. When there’s insufficient refrigerant, the AC unit struggles to cool your space adequately, leading to prolonged run times and increased energy bills.

  • Signs: Reduced cooling efficiency, hissing sound, increased energy bills, longer cooling cycles.
  • Solution: Contact a professional to repair the leak and recharge the refrigerant. An HVAC expert can locate the leak, fix it, and recharge the system, ensuring it runs smoothly again.

Sensor Problems

Air conditioners feature a thermostat sensor to measure air temperature in the evaporator coil. The AC might behave erratically if the sensor is knocked out of position. This sensor problem can cause the air conditioner to cycle constantly or act in ways that reduce comfort levels indoors. When the thermostat reads incorrect temperatures, it can lead to improper cooling or excessive energy use.

  • Signs: Inconsistent temperature control, frequent cycling on and off, uneven room temperatures.
  • Solution: Carefully adjust the sensor position or call a technician. The sensor should be near the evaporator coil but not in direct contact.

Electric Control Failure

Frequent cycling of the AC can wear out electrical components such as the compressor and fan controls. These parts are crucial for the system’s operations, and their failure can lead to a complete unit breakdown. Electrical issues can stem from various causes, including power surges, corrosion of wires and terminals, and general wear and tear.

  • Signs: AC won’t turn on or off, sporadic cooling, unresponsive controls.
  • Solution: A professional should inspect and replace any defective electrical parts. Regular electrical inspections can also help detect potential failures early.

Drainage Issues

A clogged drain might cause water damage and interfere with your air conditioner’s operation. Proper drainage is necessary to handle the humidity extracted from the air. A broken drainage system might result in water damage, the growth of mold inside the unit, or spilling over into your house.

  • Signs: Water pooling around the unit, musty odors, higher humidity levels indoors.
  • Solution: Ensure the drainage system is clear. If it is still clogged, consult a technician who can clear the blockage and check for other related issues.


Knowing these common air conditioning problems can save you time and discomfort. While some issues have straightforward solutions, others may require expert help. Keeping your unit in top shape will ensure it runs efficiently for years. Regular maintenance and awareness of signs of trouble can help you address problems before they become significant. Whether you live in New Smyrna Beach air conditioning territory or elsewhere, a well-maintained unit is critical to staying relaxed and comfortable.
