Refrigerant Leak Repair & Refrigerant Leak Detection in Winnipeg, MB
Winnipeg Commercial Refrigeration provides professional refrigerant leak repair and refrigerant leak detection backed by over 20 years of commercial refrigeration experience in Winnipeg, MB. Refrigerant is contained within a sealed refrigeration circuit and is not consumed during normal operation. When a leak develops, even a small loss of refrigerant can reduce cooling capacity, increase compressor workload, raise energy consumption and eventually lead to equipment failure if left unaddressed. We locate and repair refrigerant leaks for restaurants, grocery stores, convenience stores, healthcare facilities, warehouses and commercial refrigeration systems throughout Winnipeg.
Accurate refrigerant leak repair involves much more than simply adding refrigerant. Our technicians use professional leak detection equipment, pressure testing and proven diagnostic procedures to locate the source of the leak before carrying out permanent repairs. Once the sealed system has been repaired, we evacuate moisture and air from the refrigeration circuit, recharge the system to manufacturer specifications and verify proper operating pressures and cooling performance.
We proudly provide commercial refrigerant leak repair and leak detection throughout Winnipeg and surrounding communities, including Steinbach, Selkirk, Niverville, East St. Paul, West St. Paul, Headingley, Oak Bluff, Stonewall, Oakbank and communities across Southern Manitoba.

Signs Of A Refrigerant Leak
Inconsistent Cooling & Rising Storage Temperatures
One of the earliest signs of a refrigerant leak is difficulty maintaining consistent temperatures. Walk-in coolers may struggle to stay between 1°C and 4°C, while walk-in freezers may no longer maintain temperatures below -18°C. As refrigerant levels decrease, the system loses cooling capacity, increasing the risk of food spoilage, inventory loss and regulatory compliance issues.
Longer Compressor Run Times & Higher Energy Bills
When refrigerant levels drop, the compressor must operate longer to achieve the desired temperature. Extended run times place additional stress on the compressor, increase electrical consumption and accelerate wear on critical refrigeration components. Businesses may notice higher utility costs even though cooling performance continues to decline.
Ice Buildup On Evaporator Coils Or Refrigerant Lines
Low refrigerant levels can cause evaporator coils or suction lines to become excessively cold, leading to frost or ice accumulation. While ice may appear to indicate the system is cooling properly, it often restricts airflow, reduces heat transfer and further decreases refrigeration performance until the underlying leak is repaired.
Bubbling Sounds, Oil Residue & Visible Leak Indicators
Small refrigerant leaks may produce faint hissing or bubbling sounds around tubing, service valves or brazed joints. Refrigerant oil often escapes alongside the refrigerant, leaving oily residue on copper lines, fittings or components. These visible signs help technicians narrow down the leak location before confirming it with professional electronic leak detection and pressure testing.
Why Refrigerant Leaks Develop
Vibration & Mechanical Fatigue
Commercial refrigeration systems experience constant vibration from compressors, condenser fan motors and normal equipment operation. Over time, this movement can place stress on copper tubing, brazed joints and mechanical connections, eventually creating small cracks or weakened areas where refrigerant can escape.
Corrosion & Coil Deterioration
Evaporator and condenser coils are exposed to moisture, cleaning chemicals, salt, grease and other contaminants that can gradually corrode metal surfaces. In restaurants, commercial kitchens and food processing facilities throughout Winnipeg, corrosion can eventually create pinhole leaks that reduce system efficiency and cooling performance.
Damaged Service Valves, Fittings & Components
Leaks commonly occur around Schrader valves, flare fittings, filter driers, pressure switches and other serviceable components within the refrigeration circuit. Aging seals, loose connections or worn valve cores can allow refrigerant to escape slowly, making early detection important before cooling capacity is significantly affected.
Improper Previous Repairs Or Physical Damage
Poor brazing techniques, incorrect installation practices or accidental damage during maintenance can compromise the integrity of the sealed refrigeration circuit. Refrigerant lines that are bent, rubbed against surrounding equipment or struck during routine operations may eventually develop leaks that require permanent repair rather than repeated refrigerant recharging.
Electronic Leak Detection & Pressure Testing
Electronic Refrigerant Leak Detection
Electronic leak detectors are capable of identifying extremely small refrigerant leaks that may not be visible during a standard inspection. Our technicians systematically inspect compressors, evaporator coils, condenser coils, service valves, brazed joints and refrigerant piping to accurately pinpoint the source of refrigerant loss without unnecessary component replacement.
Nitrogen Pressure Testing For Sealed Systems
When a leak cannot be located during normal system operation, the refrigerant is safely recovered and the sealed refrigeration circuit is pressurized with dry nitrogen. This allows us to verify system integrity, isolate pressure loss and identify leaks that may only appear under operating pressure without introducing moisture into the system.
Bubble Testing & Leak Verification
Once a suspected leak location has been identified, specialized leak detection solution is applied to confirm the exact source. Even very small pinhole leaks around copper tubing, fittings, Schrader valves or brazed joints can be visually verified, ensuring repairs are performed precisely where they're needed rather than relying on guesswork.
Accurate Diagnosis Before Any Refrigerant Is Added
Simply adding refrigerant without locating and repairing the leak only provides a temporary solution. We verify the source of refrigerant loss before recommending repairs, helping prevent repeat service calls, unnecessary refrigerant costs and continued compressor strain while restoring reliable refrigeration performance.
Our Refrigerant Leak Repair Process
1. Confirming The Refrigerant Leak
We begin by inspecting the refrigeration system and verifying that refrigerant loss is the cause of the cooling problem. System pressures, temperatures and overall performance are evaluated before electronic leak detection and pressure testing are used to locate the source of the leak accurately.
2. Recovering Refrigerant & Repairing The Leak
Before any repairs are performed, the remaining refrigerant is safely recovered using approved recovery equipment. Depending on the location of the leak, repairs may involve replacing damaged components, repairing copper tubing or re-brazing leaking joints to fully restore the integrity of the sealed refrigeration circuit.
3. Evacuating The System & Recharging Refrigerant
Once the repair has been completed, the refrigeration circuit is pressure tested, evacuated with a vacuum pump to remove air and moisture, and verified using a micron gauge. The system is then recharged with the correct type and quantity of refrigerant according to the manufacturer's specifications for reliable, efficient operation.
4. Final Performance Testing & Leak Verification
After charging the system, we verify operating pressures, superheat, subcooling, temperature performance and overall cooling capacity. A final leak inspection confirms the sealed refrigeration circuit is holding pressure properly, ensuring your commercial refrigeration equipment is operating efficiently and ready to return to service.
Refrigerant Leak Repair FAQs
Can I simply add more refrigerant instead of repairing the leak?
No. Refrigerant operates within a sealed system and is not consumed during normal operation. If refrigerant levels are low, a leak is present and must be located and repaired before the system is recharged. Simply adding refrigerant is only a temporary solution and can lead to recurring cooling problems and compressor damage.
What causes refrigerant leaks in commercial refrigeration systems?
Leaks commonly develop from vibration, corrosion, damaged copper tubing, deteriorated brazed joints, worn Schrader valves or physical damage to refrigeration components. As equipment ages, these issues can allow refrigerant to slowly escape from the sealed refrigeration circuit.
How do you find a refrigerant leak?
Our technicians use professional electronic leak detectors, nitrogen pressure testing and leak verification methods to accurately locate the source of refrigerant loss. This allows repairs to be made at the exact leak location rather than relying on guesswork or repeatedly adding refrigerant.
Is it safe to continue operating equipment with a refrigerant leak?
It's not recommended. Low refrigerant levels reduce cooling capacity, force the compressor to work harder and increase electrical consumption. Continuing to operate the system can lead to overheating, compressor failure, product spoilage and significantly more expensive repairs.
Will repairing the leak restore normal cooling performance?
In most cases, yes. Once the leak has been permanently repaired, the refrigeration circuit is evacuated, recharged with the correct amount of refrigerant and performance tested to verify proper operating pressures, temperatures and cooling efficiency.
Do you repair refrigerant leaks for all commercial refrigeration equipment?
Yes. We repair refrigerant leaks in walk-in coolers, walk-in freezers, reach-in refrigerators and freezers, display cases, prep tables, undercounter refrigeration units, beverage coolers and many other commercial refrigeration systems throughout Winnipeg and Southern Manitoba.
