Common Air Conditioner Problems That We Fix

Air conditioners are essential for maintaining comfort in homes and businesses, especially during swelteringly unbearable summer months. However, like any complex system, they can encounter issues that disrupt their performance. Below, we explore the most common air conditioner problems and how our expert technicians address them to restore your unit’s efficiency and keep your space cool.

1. Air Conditioner Not Cooling Properly

One of the most frequent complaints is an air conditioner that fails to cool effectively. This issue can stem from various causes, such as low refrigerant levels, dirty air filters, or a malfunctioning compressor. Low refrigerant often results from leaks, which reduce the system’s ability to absorb and dissipate heat. Dirty filters restrict airflow, forcing the unit to work harder and less efficiently. A faulty compressor, meanwhile, may struggle to circulate refrigerant properly.

Our technicians begin by inspecting the unit to identify the root cause. We check refrigerant levels and repair any leaks before recharging the system. Air filters are cleaned or replaced to restore proper airflow. For compressor issues, we assess whether repair or replacement is the most cost-effective solution, ensuring your unit cools your space efficiently again.

2. Strange Noises Coming from the Unit

Unusual sounds like grinding, squealing, or banging from your air conditioner are often signs of mechanical issues. These noises can indicate loose or broken components, such as fan blades, belts, or motor bearings. Ignoring these sounds can lead to more significant damage over time.

Our team conducts a thorough inspection to pinpoint the source of the noise. Loose parts are tightened, worn belts are replaced, and damaged components are repaired or swapped out. For example, a squealing noise might require lubricating the motor or replacing a worn belt, while grinding could point to a failing motor bearing that needs prompt attention. Our goal is to eliminate the noise and prevent further damage to your system.

3. Air Conditioner Leaking Water

Water leaks are a common issue, particularly with window or split-system air conditioners. Leaks often occur due to a clogged drain line, improper installation, or a damaged condensate pan. Excess moisture can lead to mold growth or water damage in your home if not addressed quickly.

We tackle water leaks by clearing blockages in the drain line using specialized tools or cleaning solutions. If the unit is improperly installed, we adjust its positioning to ensure proper drainage. For a damaged condensate pan, we replace the component to prevent further leaks. Our technicians also check for humidity-related issues that might contribute to excess condensation, ensuring a comprehensive fix.

4. Frequent Cycling or Unit Not Turning On

If your air conditioner cycles on and off too frequently or fails to turn on at all, the problem could be electrical or thermostat-related. Faulty wiring, a malfunctioning thermostat, or a tripped circuit breaker can disrupt the unit’s operation. In some cases, a failing capacitor or contactor may prevent the system from starting.

Our experts perform a detailed electrical diagnostic to identify issues like faulty wiring or a malfunctioning thermostat. We recalibrate or replace the thermostat as needed and test the capacitor and contactor for proper function. If a circuit breaker has tripped, we investigate the cause to prevent future occurrences. This systematic approach ensures your unit operates reliably.

5. Foul Odors from the Air Conditioner

Unpleasant smells emanating from your air conditioner can indicate mold, mildew, or bacterial growth within the unit, often due to trapped moisture in the evaporator coil or drain pan. Electrical issues, such as burnt wiring, can also produce a distinct odor.

We address odors by thoroughly cleaning the evaporator coil and drain pan with antimicrobial solutions to eliminate mold and bacteria. If the issue is electrical, we inspect the wiring and components for signs of overheating or damage, replacing any compromised parts. Regular maintenance recommendations are provided to prevent odor recurrence, keeping your air fresh and clean.

6. Frozen Evaporator Coils

Frozen evaporator coils can cause your air conditioner to stop cooling altogether. This issue often results from restricted airflow, low refrigerant, or a malfunctioning blower fan. When coils freeze, the system cannot effectively absorb heat, leading to poor performance.

Our technicians thaw the coils and address the underlying cause. We check for airflow restrictions, such as dirty filters or blocked vents, and clear them. Refrigerant levels are verified, and any leaks are repaired. If the blower fan is faulty, we repair or replace it to restore proper airflow and prevent future freezing.

Air conditioner problems can range from minor inconveniences to major disruptions, but our skilled technicians are equipped to handle them all. Whether it’s insufficient cooling, strange noises, water leaks, electrical issues, foul odors, or frozen coils, we diagnose and fix the issue efficiently to restore your unit’s performance. Regular maintenance can prevent many of these problems, and our team is here to provide expert service to keep your air conditioner running smoothly year-round.
