Recharge To Manufacturer Specification
If a commercial HVAC system is running but not cooling as effectively as it used to, low refrigerant from an undetected leak is one of the most common causes. Refrigerant does not get “used up” like fuel. In a properly sealed system, the charge should remain stable for the entire service life.
If the charge is low, refrigerant is leaking somewhere, and simply adding more without finding and repairing the leak means paying for repeated top-offs while the compressor operates under more strain than it was designed to handle.
Headquartered in Sarasota and serving Collier County, Hillsborough County, Lee County, Manatee County, Pinellas County, Sarasota County and surrounding areas, Miller Refrigeration locates and repairs refrigerant leaks in commercial rooftop units, package systems, and split systems across Florida. Our refrigeration and HVAC experts use electronic leak detectors and other advanced diagnostic methods to identify the exact leak point, whether it is a worn valve, a corroded line, or a failed braze joint, rather than guessing or simply recharging the system and hoping the leak is small enough to ignore.
What We Provide
If your system has been topped off more than once, the leak was never repaired. We will locate it and fix it so the recharge holds.

Topping off refrigerant without finding the leak is only a temporary measure, not a true repair. The system will lose charge again, performance will decline again, and the compressor will continue to run under the added strain of low refrigerant in the meantime.
Running low on charge shortens compressor life and increases the likelihood of a much more expensive failure later. Locating and repairing the actual leak source before recharging means the solution lasts instead of needing to be repeated every few months.
Reduced cooling performance, longer run times to reach the same temperature, ice forming on the evaporator coil or refrigerant lines, and a hissing or bubbling sound near refrigerant lines can all indicate a leak.
Rising energy bills without an obvious cause are also worth investigating, since a system working harder to compensate for low refrigerant uses more electricity to deliver the same result. If you notice any of these issues at your commercial facility, Miller Refrigeration can help diagnose and resolve the problem.
Common Questions
Reduced cooling, longer run times, or ice on the lines usually means the charge is low and a leak is active. We provide 24-hour emergency service with fast dispatch, on-site diagnostics, and clear repair recommendations.
