Refrigerant Leaks and Frozen Coils Resolved
Refrigeration repair, installation, and troubleshooting for commercial properties in McAllen, Texas.
When refrigerant leaks from your system in McAllen, you will notice longer run times, warmer holding temperatures, and frost buildup on the evaporator coils. Restaurants lose product, medical facilities risk vaccine spoilage, and retail coolers fail to keep inventory at safe temperatures. Refrigeration problems do not wait, and the longer the system runs low on charge, the more strain it puts on the compressor.
Freedom Air & Refrigeration installs, repairs, and troubleshoots refrigeration systems across McAllen. We address refrigerant leaks, frozen evaporator coils, blocked expansion valves, and low refrigerant charge. Our work supports offices, retail centers, restaurants, warehouses, healthcare facilities, data centers, and schools where temperature control is part of daily operations.
If your refrigeration system is not holding temperature or you see ice forming on the coils, reach out to Freedom Air & Refrigeration for a diagnostic visit in McAllen.
We Track Down Leaks and Restore Proper Charge
Our technicians use electronic leak detectors and nitrogen pressure tests to locate refrigerant leaks in lines, coils, and valve assemblies. In McAllen facilities with walk-in coolers or reach-in units, we also inspect door seals and defrost cycles that can contribute to ice buildup and uneven cooling.
After repairing the leak and evacuating moisture from the system, we recharge the refrigerant to the manufacturer specification and verify that the evaporator coil is pulling heat as expected. You will notice that the unit reaches setpoint faster, frost disappears from the coil face, and product temperatures stabilize within the safe range.
Blocked expansion valves reduce refrigerant flow and cause the evaporator to ice over, so we clean or replace the valve and check the filter drier for contamination. This type of work is common in older refrigeration systems or units that have experienced compressor failure in the past.
Common Concerns About Refrigeration Repair
These questions reflect what restaurant managers, facility supervisors, and business owners in McAllen ask when dealing with refrigeration failures.
What causes refrigerant to leak?
Leaks occur at brazed joints, valve cores, coil connections, and areas where vibration or corrosion has weakened the tubing. We repair the leak and pressure test the system before adding refrigerant.
Why is my evaporator coil frozen?
Frozen coils are usually caused by low refrigerant, restricted airflow, or a faulty defrost cycle. We check the charge level, clean the coil, and test the defrost timer and heater to restore normal operation.
How long does a refrigerant repair take?
Most leak repairs and recharges take two to four hours depending on the location of the leak and whether we need to braze new fittings or replace a section of line. We confirm the repair holds pressure before leaving the site.
What is an expansion valve and when does it fail?
The expansion valve controls refrigerant flow into the evaporator coil. It can clog with debris or lose calibration, causing the coil to ice over or the system to lose capacity.
Do you install new refrigeration equipment?
Yes, we install walk-in coolers, reach-in units, condensing units, and evaporator coils for restaurants, retail spaces, and warehouses in McAllen. We also help with equipment selection based on your cooling load and space requirements.
Whether you operate a restaurant kitchen, a medical clinic, or a warehouse with temperature-sensitive inventory, Freedom Air & Refrigeration provides refrigeration repair and installation that keeps your operation running. Get in touch to schedule service in McAllen.
