In the fast-paced world of Lubbock’s commercial kitchens, warehouses, and retail spaces, your refrigeration system is the unsung hero. It works 24/7 to protect your inventory and keep your doors open. However, even the most robust systems can develop a refrigerant leak.
Because refrigerant is a gas at room temperature, these leaks are often invisible—but their impact on your bottom line is very real. At Lubbock Refrigeration, we want to help you catch these issues before they turn into a full-scale equipment failure. Here are the red flags every business owner should watch for.
1. Fluctuating or Rising Temperatures
The most obvious sign of a leak is a system that simply isn’t holding its set point. If your walk-in cooler is sitting at 45°F instead of 38°F, or if your display cases are struggling to stay frosted, the cooling capacity has likely been compromised. When refrigerant levels drop, the system loses its ability to absorb and move heat effectively.
2. Oily Residue Around Connections
Refrigerant travels through your system mixed with a special lubricant for the compressor. When gas escapes through a tiny crack or a loose fitting, it often carries a small amount of this oil with it.

What to look for: Check the copper joints, service valves, and the evaporator coil for a “greasy” or oily film. Dust often sticks to these spots, making them look like dark, grimy patches.
3. Hissing or Bubbling Sounds
While commercial units are naturally noisy, a distinct hissing sound near the indoor or outdoor coils is a major red flag. This is the sound of high-pressure gas escaping. In some systems with sight glasses (small windows into the refrigerant line), you might also see constant bubbling or “foaming,” which indicates an insufficient charge.
4. Ice Build-up on the Evaporator Coil
It seems counterintuitive, but a lack of refrigerant actually causes coils to freeze over. When the refrigerant level is low, the remaining liquid operates at a much lower temperature than intended. This causes the moisture in the air to flash-freeze onto the coils, creating an insulating layer of ice that further chokes the system’s efficiency.
5. Spiking Energy Bills
A leaking system doesn’t just stop; it tries to compensate. Your compressor will run longer—or even continuously—to try and reach the thermostat’s target. If you notice a sudden, unexplained jump in your Lubbock Power & Light bill, your refrigeration system might be working double-time to make up for a leak.
Why You Shouldn’t Wait
Refrigerant leaks are “progressive” problems. A tiny pinhole leak today can lead to a burnt-out compressor tomorrow—a repair that is significantly more expensive than a simple leak fix and recharge. Furthermore, leaking refrigerant is a regulated substance that can pose environmental and safety risks if left unaddressed.
Expert Detection and Repair
At Lubbock Refrigeration, we use advanced electronic leak detectors and ultrasonic tools to find even the smallest “silent” leaks. We don’t just “top off” the system; we find the source, seal it, and ensure your system is running at peak efficiency.
