Is your commercial air conditioning system failing to cool effectively, or has its performance gradually declined? A common reason for reduced efficiency is a low refrigerant charge. Refrigerant is the essential chemical compound that absorbs heat from your indoor environment and releases it outside, facilitating the cooling process. Without the correct amount, your AC unit cannot operate at its optimal level, leading to discomfort and increased energy consumption.
Our F-Gas certified engineers provide professional AC refrigerant recharge services for a wide range of commercial air conditioning systems throughout London and the M25. We ensure that your system is correctly diagnosed, any leaks addressed, and the appropriate refrigerant type and quantity are safely added, restoring your AC unit's cooling capacity and efficiency.

Understanding AC Refrigerant and Its Importance
Refrigerant, often incorrectly referred to as 'Freon' (which is a brand name for certain refrigerants), is a vital component of any air conditioning system. It cycles through the unit, changing state between liquid and gas to absorb heat from your premises and dissipate it elsewhere. This process, known as the refrigeration cycle, is how your air conditioner cools the air. A precise amount of refrigerant is required for the system to function correctly; too little or too much can both lead to problems.
Unlike a car's engine oil, refrigerant is not 'consumed' during normal operation. If your system is low on refrigerant, it almost always indicates a leak somewhere within the sealed system. Our engineers are trained to identify and repair these leaks before recharging, ensuring the long-term integrity and efficiency of your air conditioning unit.
Signs Your AC System Needs a Refrigerant Recharge
Identifying the signs of low refrigerant early can prevent further damage to your air conditioning system and restore comfort to your commercial space. Pay attention to these common indicators that suggest your AC unit may require a professional refrigerant recharge.
Ignoring these signs can lead to increased energy bills, premature wear on components, and ultimately, system breakdown. Prompt action can save you from more extensive and costly repairs in the future.
- Decreased Cooling Performance: The most obvious sign is that your AC is no longer cooling as effectively as it once did, or the air coming from the vents isn't as cold.
- Increased Energy Bills: A system working harder to achieve the desired temperature due to low refrigerant will consume more electricity, driving up your operational costs.
- Hissing or Bubbling Noises: These sounds can indicate a refrigerant leak within the system, often heard near the indoor or outdoor unit.
- Ice Formation on Coils: If you notice ice build-up on the evaporator coils of your indoor unit, it's a strong indicator of low refrigerant.
- AC Runs Continuously: The unit struggles to reach the thermostat setting and runs for longer periods, often without success.
- Frozen Suction Line: The larger, insulated copper line running from the outdoor unit to the indoor unit may feel unusually cold or have ice on it.
Our Professional AC Refrigerant Recharge Process
Our comprehensive AC recharge service is performed by REFCOM F-Gas certified engineers, ensuring adherence to the highest industry standards and environmental regulations. Our meticulous approach guarantees a safe, efficient, and lasting solution for your commercial air conditioning needs.
We are equipped to handle a variety of refrigerant types, including R410A, R32, R407C, and older refrigerants where applicable and legally permissible. Our commitment is to restore your system's performance while complying with all relevant F-Gas regulations.
- System Inspection and Diagnostic: Our engineers will conduct a thorough inspection of your AC unit, including pressure readings and temperature differential checks, to confirm if low refrigerant is the issue.
- Leak Detection and Repair: Since low refrigerant nearly always indicates a leak, we utilise advanced leak detection methods (e.g., electronic leak detectors, UV dyes, soap bubbles) to pinpoint the exact location of any refrigerant leaks. We then provide professional repairs to seal the system.
- Refrigerant Recovery (if necessary): If repairs require opening the system, existing refrigerant will be safely recovered using specialised equipment to prevent release into the atmosphere, in line with F-Gas regulations.
- Vacuuming the System: After repairs, the system is thoroughly evacuated using a vacuum pump to remove all non-condensable gases and moisture, which can otherwise damage the compressor and impair efficiency.
- Precise Refrigerant Recharge: The appropriate type and exact amount of refrigerant, specified by the manufacturer, is then weighed and safely charged into the system.
- Performance Testing: Once recharged, the system is thoroughly tested to ensure proper operation, cooling efficiency, and to verify that all pressures and temperatures are within manufacturer specifications.

Frequently asked questions
What is an AC refrigerant recharge?
An AC refrigerant recharge is the process of adding refrigerant back into your air conditioning system to restore it to the manufacturer's specified charge level. This is typically done after a leak has been identified and repaired, as refrigerant is not consumed during normal operation.
How often does commercial AC need a refrigerant recharge?
Ideally, a properly sealed commercial AC system should never need a refrigerant recharge. If a recharge is required, it indicates a leak in the system that needs to be detected and repaired. Routine maintenance includes checking refrigerant levels but not routinely 'topping up' if there's no leak.
Is a refrigerant leak dangerous?
Yes, refrigerant leaks can be dangerous. Besides harming the environment, certain refrigerants can displace oxygen in enclosed spaces, posing an asphyxiation risk. They can also cause frostbite upon contact and, when heated, can decompose into hazardous substances. Professional handling is essential.
What happens if my AC system is overcharged with refrigerant?
Overcharging an AC system with refrigerant is as problematic as undercharging. It can lead to abnormally high pressures within the system, potentially damaging the compressor, reducing efficiency, causing the unit to cycle on and off frequently, and potentially leading to a system breakdown.
Can I recharge my commercial AC system myself?
No, it is strongly advised not to attempt to recharge a commercial AC system yourself. This task requires specialised tools, F-Gas certification, and a thorough understanding of refrigerant properties and safety protocols. Incorrect handling can lead to system damage, environmental harm, and personal injury, and is illegal under F-Gas regulations.
