Our Air Conditioning Repair Services Include:

Refrigerant Leak Repair

Refrigerant leaks are a common concern in air conditioning systems. They can compromise your AC’s cooling efficiency, increase energy consumption and even pose health risks. Our technicians are skilled in detecting and repairing leaks while ensuring your system is filled with the right refrigerant levels.  Detecting refrigerant leaks early is crucial. 

Signs of Refrigerant Leaks:

  • Reduced Cooling Performance
  • Longer Cooling Cycles
  • Hissing Sounds Near the AC Unit
  • Ice Formation on Evaporator Coils
  • Increased Energy Bills

Causes of Refrigerant Leaks:

  • Corrosion and Aging Components: Over time, he metal components within your AC system can corrode, leading to tiny openings through which refrigerant can escape.
  • Vibration and Wear: The constant operation of your AC unit can cause vibrations that may lead to wear and tear on connections, potentially causing leaks.
  • Poor Installation: Incorrect installation practices can result in improperly sealed connections, increasing the likelihood of refrigerant leaks.
  • Manufacturing Defects: Occasionally, manufacturing defects can result in weak points in the AC system that eventually lead to leaks.
  • Physical Damage: Accidental impacts, harsh weather, or other physical damage to your AC unit can create cracks or openings that allow refrigerant to leak.
  • Prolonged Usage: AC systems that are used extensively over the years are more susceptible to developing leaks due to the strain on components.
Our technicians will detect and locate the source of the leak, whether it’s in the evaporator coil, condenser, or any other component and repair the leak using appropriate methods, which may include soldering, patching, or replacing damaged components. Once we ensure that all connections are properly tightened and sealed to prevent future leaks, we recharge your AC system with the correct amount of refrigerant to restore its optimal cooling efficiency. Our experts provide recommendations to prevent future leaks, including routine maintenance and regular inspections.

Electrical Component Repair

Faulty wiring, capacitor problems, or issues with relays can disrupt your AC’s functionality. Our experts will diagnose and repair electrical components to restore your system’s operation.

Evaporator Coil Cleaning and Repair

Clean evaporator coils are essential for efficient cooling. We provide thorough cleaning and repair services to maintain your AC’s performance.


Leaky or improperly insulated ductwork can lead to cooled air escaping before it reaches your living spaces. Our experts will inspect and repair your ductwork to enhance energy efficiency.

Compressor and Condenser Repair

The compressor and condenser are vital components of your air conditioning system, responsible for maintaining the cooling process that keeps your indoor spaces comfortable. Understanding the importance of these components and recognizing when repair is necessary can help you ensure the longevity and efficiency of your AC system. We specialize in diagnosing and repairing issues that affect these components, ensuring optimal cooling performance.

  • The Compressor: Often referred to as the “heart” of your AC system, the compressor circulates refrigerant, which absorbs heat from indoor air and releases it outdoors. This process is essential for cooling your indoor spaces effectively.
  • The Condenser: The condenser works in collaboration with the compressor. It receives high-pressure, high-temperature refrigerant vapor from the compressor and transforms it into a liquid state, releasing heat in the process. This step is crucial for maintaining the refrigerant cycle.

Signs of Issues with Compressors and Condensers:

  • Warm Air
  • Unusual Noises
  • Short Cycling
  • High Energy Bills

Causes of Compressor and Condenser Issues:

  • Wear and Tear
  • Electrical Problems
  • Contaminants
  • Lack of Maintenance
  • Refrigerant Issues
