If your fridge is running but not keeping food cold, or the freezer is working but the fridge compartment is warm, refrigerant loss is one of the most likely causes. Fridge regassing — refilling the refrigerant circuit to restore the correct charge — is a service we carry out regularly across Centurion homes and businesses.
Centurion Appliance Repairs provides professional fridge regassing services throughout Centurion for domestic fridges, commercial display fridges, bar fridges, chest freezers, and cold rooms. Our certified refrigeration technicians carry R600a, R134a, and R22 refrigerants and the diagnostic equipment required to identify, locate, and repair refrigerant leaks correctly before any recharge is carried out.
Before anything else, there is one thing every Centurion fridge owner should understand: a fridge refrigerant circuit is a hermetically sealed, factory-closed system. In a correctly functioning fridge with no faults, the refrigerant charge remains constant for the entire working life of the appliance — it does not get used up, it does not expire, and it does not need periodic replenishment. If your fridge has lost refrigerant, it is because there is a leak somewhere in the system. That leak will not seal itself. A recharge without finding and repairing the leak is a temporary measure that will leave you needing another recharge within months.
We locate the leak, repair it, and recharge to the correct specification. That is the only approach that produces a lasting result.

Fridge regassing is the process of refilling the refrigerant circuit of a refrigerator or freezer with the correct type and amount of refrigerant gas to restore the system to its specified operating charge.
Refrigerant is the substance that makes refrigeration possible. It circulates through the refrigeration circuit — compressor, condenser, expansion device, evaporator — absorbing heat from inside the fridge cabinet as it evaporates in the evaporator coil, and releasing that heat outside the fridge as it condenses in the condenser coil. The temperature change caused by the phase transition of the refrigerant — from liquid to gas as it absorbs heat, and from gas back to liquid as it rejects heat — is what cools the interior of the fridge.
When the refrigerant charge is depleted through a leak, the system cannot complete this heat transfer cycle effectively. The evaporator coil becomes too cold in some areas and too warm in others, the compressor runs harder than designed to compensate for the reduced pressure differential, and the cabinet temperature rises progressively until the fridge can no longer cool adequately.
Regassing restores the refrigerant level to the manufacturer’s specified charge, allowing the system to operate at design pressures and temperatures again.
Fridge running but not cooling adequately The most common and most obvious symptom. The compressor is running — you can hear it — but the fridge cabinet is not maintaining a safe food storage temperature. Items that should be cold are soft or tepid. This symptom can indicate several faults including a thermostat problem or a defrost system issue, but a refrigerant leak is one of the primary causes.
Freezer section cold but fridge section warm When the fridge compartment is noticeably warmer than it should be while the freezer section remains cold, there are two likely causes — a defrost system fault causing evaporator icing that blocks airflow to the fridge section, or a low refrigerant charge. Both require on-site diagnosis to confirm. This symptom pattern is one of the most common fridge complaints we attend to in Centurion.
Fridge cooling less effectively than it used to Gradual deterioration in cooling performance over one or two years — the fridge used to be reliably cold but is now slightly warmer than it should be — is the characteristic pattern of a slow, small refrigerant leak. The charge depletes incrementally, producing a slow decline rather than a sudden failure.
Unusual amounts of ice or frost building up inside the cabinet Counterintuitively, a low refrigerant charge can cause ice to form in unusual patterns inside the fridge. When the charge drops, the evaporator surface temperature distribution changes in ways that cause frost to form in unexpected areas. This is different from the heavy, blocking frost that indicates a defrost system fault — the pattern and location of the frost help our technicians distinguish between the two.
Food spoiling faster than expected If food items that should keep for several days are deteriorating prematurely, the fridge temperature is likely higher than it appears. Many fridges continue to display or feel cool even when the cabinet temperature has risen to a level where bacterial growth is occurring — particularly in the upper sections of the cabinet.
Compressor running continuously without switching off A compressor that never cycles off is working harder than designed to try to maintain cabinet temperature against a refrigerant circuit that is no longer operating efficiently. This increases electricity consumption and accelerates compressor wear. If you notice your fridge making constant compressor noise rather than cycling on and off periodically, it should be investigated.
Oily or greasy residue on the refrigerant pipes or pipe connections at the back of the fridge Refrigerant oil circulates with the refrigerant in the system. When a leak develops at a pipe joint or connection, refrigerant escapes and the oil carried with it leaves a visible residue at the leak point. An oily, greasy, or slightly shiny deposit on the copper pipes at the back of the fridge — particularly at the joints where the pipes connect to the compressor — is a visible indicator of a refrigerant leak.
Ice cream that is not fully frozen or is soft Ice cream requires a storage temperature of minus 18 degrees Celsius to remain properly frozen. If ice cream that has been in the freezer is soft, the freezer is not reaching the correct temperature. This can be caused by low refrigerant, a failing compressor, or a door seal failure allowing warm air infiltration.
This is the most important thing to understand about fridge regassing — and unfortunately one of the most frequently ignored points in the Centurion market.
When refrigerant has leaked from a fridge, the leak point is a physical defect in the system — a pinhole in the evaporator coil caused by corrosion, a joint connection that has vibrated loose, a cracked fitting, or a damaged pipe. The leak does not close itself. It continues to leak after a recharge, at the same rate it leaked before.
A technician who recharges a fridge without finding and repairing the leak is providing a service that will leave the fridge cooling normally for a few weeks or months before declining again to the same state. You will need another recharge — and another. Each recharge without a repair is money spent on a problem that is not being solved.
Beyond the cost to you, releasing refrigerant into the atmosphere is an environmental obligation. Refrigerants are controlled substances — R600a and R134a, the two most common fridge refrigerants — are subject to handling and disposal regulations. Releasing them through repeated recharges of a leaking system without repair is not responsible practice.
The professional approach — and the only one we offer — is to find the leak, repair it, and then recharge. This produces a lasting result.
Understanding which refrigerant your fridge uses matters because the handling requirements, safety considerations, and service procedures differ between refrigerant types.
R600a (Isobutane) R600a is the refrigerant used in the overwhelming majority of modern domestic fridges sold in South Africa today, including current Hisense, Samsung, LG, Defy, Bosch, and other major brand models. It is a hydrocarbon refrigerant — essentially a purified form of isobutane — with an extremely low global warming potential and zero ozone depletion potential. It is an environmentally superior refrigerant compared to its predecessors.
R600a is, however, flammable. It is classified as a highly flammable gas and requires specific handling protocols, appropriate safety equipment, dedicated tools, and a well-ventilated working environment. All sparks and ignition sources must be eliminated before working with R600a. The quantity used in a domestic fridge is small — typically 30 to 100 grams — which limits the realistic flammability risk in normal use, but the handling requirements for technicians working with the refrigerant in service conditions are non-negotiable.
DIY fridge regassing with R600a is not safe and should not be attempted under any circumstances. Beyond the safety risk, it requires calibrated weighing equipment, a vacuum pump, appropriate recovery equipment, and knowledge of the correct charge weight for the specific model.
R134a R134a was the standard domestic refrigerant in fridges manufactured from approximately the mid-1990s to the early 2010s. It is not flammable and has a lower immediate safety risk during handling than R600a. However, it has a significantly higher global warming potential than R600a, which is why it has been progressively replaced. Many older fridges in Centurion homes — particularly units 10 to 15 or more years old — still use R134a.
R134a requires certified handling equipment, a vacuum pump, and accurate charge measurement equipment. The charge weight for a specific model is specified by the manufacturer and must be followed precisely — over-charging a fridge with R134a reduces efficiency and risks compressor damage.
R22 R22 is a refrigerant used in older commercial and some domestic refrigeration equipment predating the mid-1990s. It is being phased out globally due to its ozone depletion potential, and its availability and cost have increased significantly as supplies decline. We carry R22 for service of existing legacy systems where repair is still economically justified, and we advise clients on the long-term economics of continuing to service R22 equipment versus replacement.
Step 1 — Symptom review and visual inspection The technician discusses what you have observed and inspects the fridge — checking for visible signs of refrigerant leakage such as oily residue on the pipes, abnormal frost patterns on the back wall or evaporator, the condition of the door seals, and any unusual sounds from the compressor or fans.
Step 2 — Operational assessment The technician assesses compressor cycling behaviour, evaporator frost pattern, condenser condition, and basic system performance to establish whether refrigerant loss is the most likely cause of the fault, or whether a thermostat, defrost system, or other component fault is the primary issue.
Step 3 — Leak detection Where refrigerant loss is confirmed or suspected, the technician carries out leak detection. The method used depends on the refrigerant type. For R600a and R134a, electronic leak detectors sensitive to the specific refrigerant are used to systematically check all potential leak points — the evaporator coil inside the freezer compartment, the condenser coil at the back or underneath the fridge, the compressor connections, and all refrigerant pipe joints. For small or intermittent leaks, nitrogen pressure testing may be used to identify the leak location.
Step 4 — Leak repair The leak point is repaired using the appropriate method. A loose flare fitting is retightened or re-flared. A pinhole in the evaporator coil resulting from acidic corrosion — the most common site of refrigerant leaks in domestic fridges — is assessed for repair viability. Evaporator coil leaks in aluminium tube-and-fin evaporators can sometimes be brazed, but in many cases the evaporator requires replacement, particularly when the corrosion is widespread. We provide an honest assessment of the repair cost versus the replacement value of the fridge before any decision is made.
Step 5 — System evacuation After the leak repair, the system is evacuated using a vacuum pump to remove any air and moisture that may have entered the circuit through the leak point. Moisture in a fridge refrigerant circuit causes ice blockage at the expansion device and acid formation that damages the compressor. Proper evacuation to an adequate vacuum level before recharging is a non-negotiable step in a correctly performed regas.
Step 6 — Refrigerant recharge The correct refrigerant is charged into the system by weight using calibrated scales, to the charge weight specified by the manufacturer for the specific model. This precision is critical — both undercharging and overcharging produce poor performance and risk compressor damage. The charge weight is always specified on the fridge’s rating plate or in the manufacturer’s service documentation. We do not estimate the charge by feel or pressure alone.
Step 7 — Performance verification After recharging, the technician monitors the fridge to confirm that it reaches operating temperature, that the evaporator coil is frosting evenly, and that the compressor is cycling correctly. The visit is not complete until the fridge is confirmed to be cooling effectively.
Understanding the most common leak locations helps explain why proper leak detection is essential and why some leaks are more straightforward to repair than others.
Evaporator coil corrosion The evaporator coil inside the freezer compartment is the most common leak location in domestic fridges. Over time, food acids, cleaning chemicals, and ambient moisture attack the aluminium tube-and-fin evaporator, creating pinhole leaks. These are often very small and develop slowly, producing gradual performance decline rather than sudden failure. Evaporator corrosion leaks are the most common reason fridges need regassing in Centurion and across South Africa.
Flare fittings and joint connections The joints where the refrigerant pipes connect to the compressor, the condenser, and the service valves are potential leak points, particularly on fridges that have experienced vibration or been moved. A loose or poorly made flare fitting can leak slowly over time. These are typically straightforward to repair — retightening or re-flaring the connection.
Compressor body seals Older compressors can develop seal leaks as the rubber seals around the electrical feed-throughs deteriorate. This is more common on compressors over 10 to 15 years old.
Condenser coil The condenser coil — typically located on the back wall of older fridges or underneath in newer models — can develop leaks from physical damage or corrosion, though this is less common than evaporator leaks.
The cost of fridge regassing in Centurion depends on the refrigerant type, the location and extent of the leak, and the repair method required. Below are current indicative price ranges.
| Service | Estimated Cost |
|---|---|
| Diagnostic visit and refrigerant system assessment | R500 – R800 |
| Leak detection (electronic and visual) | R500 – R900 |
| Refrigerant recharge — R600a (domestic fridge) | R700 – R1 100 |
| Refrigerant recharge — R134a (older domestic fridge) | R800 – R1 200 |
| Refrigerant recharge — R22 (older commercial/domestic) | R1 000 – R1 800 |
| Flare fitting repair or re-flare | R600 – R1 000 |
| System evacuation (vacuum) before recharge | R500 – R800 |
| Evaporator coil assessment and repair | R800 – R2 500 |
| Evaporator coil replacement | R1 500 – R3 500 |
| Complete regas service (detection, repair, vacuum, recharge) | R1 500 – R2 800 |
Commercial fridge regassing — for display fridges, bottle coolers, bar fridges, and commercial chest freezers — typically costs more due to larger refrigerant volumes and more complex system architecture. Commercial regassing is quoted individually on-site.
All prices are indicative. A definitive quotation is provided on-site after the leak detection and assessment phase, before any refrigerant is added and before any repair work is committed to.
A regas is almost always worth doing when the fridge is under 10 years old and the repair cost is reasonable relative to the replacement cost. A regas that costs R1 500 to R2 500 on a fridge that would cost R8 000 to R15 000 to replace is clearly cost-effective.
The calculation becomes less clear when the evaporator coil has extensive corrosion and requires full replacement — a repair that costs more and may not address other age-related wear. Or when the fridge is over 12 to 15 years old and the compressor is showing signs of fatigue alongside the refrigerant loss.
Our technicians give you an honest assessment of your specific fridge — the age, the brand, the condition of the compressor and other components, the extent of the leak damage, and the realistic repair cost — before recommending whether repair is the right choice. We do not recommend a regas that is not financially justified.
DIY fridge regassing is specifically dangerous with R600a refrigerant, which is the refrigerant used in most modern fridges. R600a is a highly flammable gas — its lower flammability limit is approximately 1.8 percent by volume in air. When working with R600a in a domestic environment, all ignition sources must be eliminated, the work area must be properly ventilated, and appropriate safety equipment must be used.
Beyond the safety risk, correct regassing requires a vacuum pump capable of pulling the system to a deep vacuum, calibrated refrigerant scales for accurate charge measurement by weight, appropriate refrigerant recovery equipment for any residual refrigerant, and knowledge of the correct charge weight for the specific model and its specific refrigerant type. Without these tools and knowledge, even a technically capable person cannot regas a fridge correctly.
An over-charged fridge runs at elevated pressures that can damage the compressor and reduce efficiency. An under-charged fridge cools poorly and the compressor runs continuously under abnormal conditions. An improperly evacuated system will develop moisture-related blockage at the expansion device within weeks.

How do I know if my fridge needs regassing or has a different fault? The symptoms of low refrigerant — poor cooling, the fridge section warm while the freezer works, gradual performance decline — can overlap with a defrost system fault or a thermostat problem. The only reliable way to confirm refrigerant loss is through an on-site assessment by a qualified technician who can evaluate the evaporator frost pattern, compressor cycling behaviour, and where needed, check system pressures. We do not recommend booking a regas before a diagnostic has been carried out — adding refrigerant to a system that has a defrost fault or thermostat problem will not resolve the issue.
How long does a fridge regas take? A complete fridge regas visit — including leak detection, leak repair, system evacuation, and recharge — typically takes one to two hours for a standard domestic fridge. More complex cases where an evaporator coil repair or replacement is required will take longer.
Can my fridge be regassed if it has an R600a leak? Yes. R600a is the standard refrigerant in modern fridges and it is entirely possible to regas an R600a system — it requires specific safety protocols, appropriate tools, and certified technicians. We carry R600a and the equipment needed to handle it safely. The key requirement is that the leak source is found and repaired before the recharge is carried out.
Why is R600a used in modern fridges if it is flammable? R600a became the preferred domestic fridge refrigerant because of its environmental properties — it has essentially no global warming potential and does not damage the ozone layer. The flammability risk is managed through careful system design by manufacturers — the quantity of R600a in a domestic fridge is very small, and the system is hermetically sealed in normal use. The risk is primarily a concern for service technicians working on the system, not for the homeowner using the fridge normally.
My fridge has been regassed before but keeps losing gas — what is wrong? The leak was not properly repaired, or was not repaired at all, during previous service visits. If your fridge has needed regassing more than once in a few years, it has a recurring leak that a previous technician did not address correctly. Call us and we will carry out proper leak detection and a lasting repair before recharging.
Does my fridge need regassing regularly? No. As explained above, a correctly functioning fridge with no leaks should never need regassing. If a previous technician has told you that your fridge needs regassing every year or two as routine maintenance, that is incorrect. A fridge that loses refrigerant has a leak. The leak should be found and repaired, after which the fridge should not need another recharge.
How much does fridge regassing cost in Centurion? A complete fridge regas service — including leak detection, repair, evacuation, and recharge — typically costs between R1 500 and R2 800 for a standard domestic fridge in the Centurion area. The cost depends on the refrigerant type, the leak location and repair complexity, and whether evaporator coil work is required. A definitive quotation is provided on-site after the diagnostic phase, before any refrigerant is added.
Do you regas commercial fridges and display fridges in Centurion? Yes. We regas commercial display fridges, bottle coolers, bar fridges, and commercial chest freezers for businesses throughout Centurion. Commercial regassing is quoted individually based on the system size and refrigerant type.
Can my fridge be regassed if the evaporator has a leak? It depends on the nature and extent of the evaporator leak. Small, isolated pinholes in the evaporator coil can sometimes be brazed or repaired. Extensive corrosion damage across multiple areas of the evaporator requires evaporator replacement rather than repair. Our technician assesses the specific condition and provides an honest recommendation — including whether the repair cost is justified relative to the age and replacement value of the fridge.
