Common Causes of Freon Leaks in AC Units

Reliable Appliance & HVAC: Understanding the Causes of Freon Leaks

John Doe was a resident of San Francisco, who owned a Lennox central AC, and had recently noticed that his air conditioning unit wasn’t working efficiently. Noticing a leak in Freon, he decided to give us a call at Reliable Appliance & HVAC, and we were able to diagnose the problem and help him out.

Freon is a type of refrigerant that helps your air conditioning system cool your home, and it is essential to ensure that your AC unit works effectively. However, Freon leaks can occur due to various reasons, and it is essential to understand what causes them to prevent potential issues.

Common Causes of Freon Leaks

Age & Wear and Tear

One of the most common Causes of Freon leaks is the age and wear and tear of your air conditioning system. Over time, the components in your AC unit like the copper tubing, evaporator coil, and compressor can become damaged, corroded, rusted, or worn, leading to Freon leaks.

Poor Installation

If your air conditioning system was installed poorly, it can result in damage to the refrigerant lines and ultimately lead to Freon leaks. That’s why it’s important to have your AC system professionally installed by experienced technicians like those at Reliable Appliance & HVAC.

Physical Damage

Your air conditioning system can sometimes suffer physical damage due to the impact of hailstones, rocks, sticks, or other debris, causing damage to the refrigerant lines and resulting in Freon leaks.

Faulty Components

At times, the fault may lie in the components installed in your air conditioning system. Defective valves, coils, or faulty seals can cause Freon leaks in your system, reducing its efficiency.

What To Do If You Suspect A Freon Leak?

If you suspect that there’s a Freon leak in your AC system, switch off the unit and contact Reliable Appliance & HVAC immediately. You may notice several common symptoms of a Freon leak, including:

  • Warm or hot air coming from the vents instead of cool air.
  • The AC running continuously without switching off.
  • Frost buildup on your air conditioning unit.

Our technicians can diagnose the problem and recommend the appropriate solution to repair the leak.

The Cost of Fixing a Freon Leak

The cost of repairing a Freon leak in your AC system can range from several hundred dollars to thousands of dollars, depending on various factors like the age of your system, the location of the leak, and the extent of the damage. For example, if you have a newer air conditioning system, it may be easier and cheaper to repair the leak. However, in the case of an older unit, it may be more cost-effective to replace the entire system.

We, at Reliable Appliance & HVAC, believe in transparent pricing and provide all our customers with a detailed estimate of the costs involved. A typical AC system charge for replacing the evaporator coil and adding Freon can range anywhere from $1,000-$2,500 for brand-specific parts and labor costs.


Freon leaks can cause a range of problems in your air conditioning system, from reduced efficiency to complete breakdowns. If you suspect a Freon leak, it’s essential to contact Reliable Appliance & HVAC right away. Our experienced technicians will diagnose the problem and recommend the best possible solution to keep your home cool and comfortable.

FAQ – Common Causes of Freon Leaks in AC Units

Q: What causes Freon leaks in AC Units?

Freon leaks can be caused by various factors, including age, corrosion, vibrations, or physical damage to the AC unit’s parts. These issues can lead to small cracks or holes in the refrigerant line, causing the refrigerant to leak gradually.
