The Truth About Freon: Expert AC Repair and Leak Detection

As Spring approaches, the temperature has already begun to rise. The cooling season will be long, with extreme heat and even more extreme humidity. Residential air conditioning is an essential building system in South Texas. Proper AC repair League City is key to your and your family’s comfort.

AC Repair League City High-Level View:

• Identify the Symptom: While refrigerant is a stable compound that should never “run out,” the appearance of ice on your AC coils or inconsistent air temperatures are the primary warning signs of a leak.
• Diagnose the Root Cause: Freon loss is always caused by a breach in the system—whether from improper installation, physical damage, or age-related wear—rather than simple usage.
• Prescribe a Permanent Cure: “Topping off” a system is only a temporary bandage; a professional leak detection and repair service from Doctor Cool is required to restore the airtight integrity of your unit and prevent costly failures.

Air conditioners function using one of several man-made compounds of refrigerant gas; this category of refrigerant is commonly called Freon. All compounds absorb and release heat, but Freon does it more efficiently than most other compounds. However, environmental engineers have discovered that Freon turns ozone into oxygen, depleting the protective ozone layer that protects us from ultraviolet rays given off by the sun. For this reason and more, Freon can be very expensive to replace.

AC Repair League City: When does it become necessary to replace Freon?

• Freon is extremely stable, so it does not degrade or break down.
• Freon is not a fuel. It does not get used up. It does not need to be “topped off.”

If it does not degrade or get used up, why is it necessary to replace Freon from time to time?

AC Repair League City: Reasons that Air Conditioners Lose Freon

Freon must be installed and kept in a completely closed network of tubes, so the replacement of Freon happens when the Freon is damaged or leaks from the system.

• Improper installation: leaving contaminants. Before Freon can be installed, the entire closed system must be emptied, leaving a vacuum. Moisture or even air will interfere with cooling/heating. Some contaminants get trapped in a filter and restrict proper refrigerant flow.
• Improper installation: improper sweating. The copper tubing of the closed system must be completely sealed, since the Freon is under pressure. Any imperfection in the pipe connections will allow the Freon to leak away.
• Manufacturer’s defect. Imperfections in material or connections during manufacturing can result in Freon leaks. These types of leaks are most common shortly after installation.
• Physical damage. The outdoor portion of the air conditioner is called the condenser unit. It is not unusual for the condenser to be struck by flying debris from a lawnmower, weed eater, or dropping branches. These are only a few of the most common sources of impact, but they can all result in the Freon leaking away.
• Age/Stress. While the Freon will not degrade, the seal of the closed network of tubes can degrade. During years of usage, minor vibrations and stress can result in micro-fractures, especially at the pipe joints. Another source of leaks due to aging is rubber seals and gaskets: these substances do tend to deteriorate over time and can release fragments into the flow. These contaminants may get caught in the flow and be collected by the filter.

AC Repair League City: How will you know if your Freon is leaking or has leaked?

• When Freon begins to leak, less Freon will be compressed within the same network of tubes. This results in the Freon reaching even lower temperatures, which freezes the humidity on the tubing. When this happens, the tubes will collect a large amount of ice. When the cooling stops, that ice melts and creates a big mess.
• Since Freon is essential for cooling, losing Freon will reduce the cooling efficiency and capacity. The air conditioner will blow cool air one day and warm air the next day.
