Air conditioning units are a staple in most households, especially during the sweltering summer months. Central to their cooling function is a substance called refrigerant, commonly known as Freon. Freon is essential for the heat exchange process that cools the air before circulating it through your home. However, many homeowners wonder: how long does Freon last in an AC unit?

.

The Lifespan of Freon

Freon, a brand name for a type of refrigerant, doesn’t get consumed or used up in the same way fuel does in a car. In a properly functioning AC unit, the refrigerant continuously cycles through the system. Unless there is a leak, it should last indefinitely. However, leaks are the primary reason for Freon depletion.

Factors Affecting Freon Levels

  1. Leaks: The most common reason for declining Freon levels is leaks in the refrigerant lines. These leaks can be caused by various factors, such as corrosion, manufacturing defects, or physical damage to the AC unit.
  2. Wear and Tear: Over time, the AC unit’s components can wear down, including the coils and connections. This wear and tear can eventually lead to leaks if not properly maintained.

Signs of Low Freon Levels

  • Warm Air: If your AC is blowing warm air, it might be a sign of low refrigerant levels.
  • Hissing Sounds: A hissing sound near the AC unit can indicate a refrigerant leak.
  • Ice Buildup: Ironically, low refrigerant levels can cause the coils to freeze due to improper pressure levels.
  • Increased Energy Bills: An inefficient AC unit trying to compensate for low refrigerant levels might lead to higher energy bills.

What to Do When Freon Levels are Low

If you suspect your AC unit is low on Freon, it’s crucial to consult a professional HVAC technician at Nx Gen. We will be able to identify and repair any leaks, recharge the refrigerant to the appropriate level, and ensure your system is running efficiently.

Understanding the lifespan of Freon in your AC unit and being aware of the signs of depletion can save you from discomfort on hot days and prevent potential damages to your cooling system. Regular maintenance and addressing issues promptly can ensure that your AC unit and its refrigerant operate optimally, keeping your home cool and comfortable for years to come.
