Our Methods for Detection of an HVAC Leak

An HVAC leak that releases refrigerant from your air conditioning system is a critical defect that requires professional intervention to pinpoint the leak and repair it. Low refrigerant charge in the system is almost always the result of leakage at some point. Continuing to operate an air conditioner with insufficient refrigerant charge due to leakage can damage critical components, including the expensive compressor.  

Signs of a Refrigerant Leak

  • Poor cooling performance. Air coming out of the supply vents doesn’t feel cool as it used to.
  • System runs longer cycles. An air conditioner with insufficient refrigerant will run longer and longer cycles to achieve thermostat settings. Monthly cooling bills may reflect this increased operating time.
  • Ice on the evaporator coil. When the refrigerant charge is below specs, the coil cannot absorb sufficient heat and condensation on the coil will freeze. Eventually, the coil becomes totally obstructed by ice and damage to system components may occur.

What Causes Leaks?

  • Refrigerant may escape due to corrosion that affects A/C coils over time. Corrosive substances in the air or a salt water environment can accelerate coil leakage.
  • Physical damage to the copper refrigerant conduit that connects the evaporator coil to the condenser coil, such as bending, impact or cutting.
  • Vibration in the system causing wear and tear or loosening refrigerant fittings and joints.

How are Leaks Resolved?

Most refrigerant leaks are tiny and not evident in a simple visual inspection. A qualified HVAC professional will use specialized leak detection equipment including an electronic sensor probe to detect the presence of leaking refrigerant gas. Bubble/foam solutions may then be applied to confirm that gas is being released and isolate the exact location of the leak.

Depending on the component involved, HVAC leak repair is generally a straightforward procedure once the location of the leak has been confirmed. After the repair is complete, the service technician will add additional refrigerant to return the level back to manufacturer’s specifications.
