Types of AC Leaks and How to Repair Them: Your Ultimate Guide

Jun 30, 2023 | Air Conditioning Repair Service

AC leaks

AC leaksDiscovering that your air conditioning system is leaking can be frustrating, but fear not! We’ll walk you through two common types of AC leaks and how to repair them, ensuring your cooling system stays in top shape. So, let’s dive into the details of water leaks and refrigerant leaks.

Different Types Of AC Leaks

AC Leak: Water

In a well-functioning air conditioning system, cold refrigerant flows through the evaporator coil, cooling warm indoor air as it passes over the coil’s surface. As a result, moisture in the air condenses and drips off the coil into a pan. This excess water is usually directed outside, away from your home.

However, sometimes you might notice water dripping inside your house, indicating a problem with the AC system. This issue could be caused by a clogged drain line, a malfunctioning condensate pump (if your system has one), or a faulty pan. While some DIY enthusiasts might attempt to fix these problems themselves, it’s often best to seek help from an experienced technician to diagnose and address the water leak effectively.

AC Leak: Refrigerant

It’s essential to know that modern air conditioning systems are designed as closed systems. Unlike filling up your car’s gas tank, you can’t simply add more refrigerant to your AC system if it’s not cooling properly.

AC leaksA properly functioning system recirculates refrigerant, so any issues like warm air blowing or strange noises likely indicate a refrigerant leak.

Beware of scams that offer to top off your refrigerant. It’s not a standard maintenance service. Maintaining your HVAC system regularly should ensure the refrigerant levels are correct.

If there’s a problem, it’s crucial to have your system checked for leaks rather than simply adding more refrigerant, as precise levels are necessary for optimal performance.

Types of Refrigerant Leaks:

  • Standing Leaks (SL): These leaks can be detected when the air conditioning unit is off.
  • Pressure Dependent Leaks (PDLs): These leaks occur as pressure builds up in the cooling system.
  • Temperature Dependent Leaks (TDLs): These happen during specific conditions like a condenser blockage, defrosting, or high ambient air.
  • Vibration Dependent Leaks (VDLs): These leaks occur when the AC unit is operational, and vibrations cause refrigerant to leak.
  • Combination Dependent Leaks (CDLs): When two or more factors contribute to a refrigerant leak, you have a CDL situation.
  • Cumulative Micro-Leaks (CMLs): Tiny leaks that can form over years of operations and AC repairs.

Common Refrigerant Leak Locations in Your AC System:

  • Evaporator Coil
  • Condensing Coil
  • Suction Line Dryer
  • Accumulator

Repairing Refrigerant Leaks

Repairing refrigerant leaks is a task best left to trained air conditioning contractors. While some patching or sealing products exist, they may lead to blockages and exacerbate the problem. Signs of a refrigerant leak include reduced cooling performance, increased energy bills, unusual noises, and the presence of ice or puddles near the system.

When you suspect a refrigerant leak, don’t delay in seeking HVAC professionals‘ assistance. Addressing the issue promptly can prevent minor problems from turning into major ones, ensuring your air conditioning system works efficiently and keeps you cool during hot summer days.

With this ultimate guide to AC leaks, you’re now equipped to identify and handle potential issues with your air conditioning system. Remember to prioritize regular AC maintenance and consult experts for any air conditioning repairs, allowing you to enjoy a consistently comfortable and refreshing indoor environment. Stay cool!
