Over time, air conditioning systems can experience a gradual loss of refrigerant, which is essential for their cooling function. This depletion is not always indicative of a leak, but rather a normal process over many years of operation. When your air conditioning system is no longer performing optimally – perhaps it's blowing warm air or struggling to maintain the desired temperature – a refrigerant recharge might be necessary to restore its efficiency and cooling capacity.
Our F-Gas certified engineers specialise in safe, compliant, and effective air conditioning refrigerant recharge services for commercial and industrial properties across London and the M25. We ensure that your system receives the correct type and amount of refrigerant, adhering strictly to environmental regulations and industry best practices to maximise performance and prolong the lifespan of your AC unit.
Understanding Air Conditioning Refrigerant
Refrigerant, often referred to as coolant or Freon (though Freon is a brand name for certain refrigerants), is the substance that absorbs heat from your indoor environment and releases it outside. It cycles through a closed system, changing state from liquid to gas and back again, facilitated by components such as the compressor, condenser, expansion valve, and evaporator.
Unlike a car air conditioning system that might require more frequent top-ups, a commercial or industrial AC unit should ideally maintain its refrigerant charge for many years. A significant or sudden loss of refrigerant often points to a leak, which must be identified and repaired before any recharge is performed. Simply adding more refrigerant without addressing a leak is a temporary fix that wastes resources and can damage the environment.
When is an AC Refrigerant Recharge Necessary?
A proper air conditioning system should not require frequent refrigerant recharges. If your system is losing refrigerant, it's typically due to a small, persistent leak rather than normal consumption. However, after extensive repairs, component replacement, or as part of a very long-term maintenance cycle for older systems, a full evacuation and recharge may be specified.
Signs that your air conditioning system might be low on refrigerant include: reduced cooling performance, the system running for longer periods to achieve the set temperature, ice forming on the evaporator coil (inside unit), or unusual hissing sounds from the outdoor unit. Our engineers conduct thorough diagnostics to determine the root cause of any performance issues before recommending a recharge.
Our F-Gas Certified Recharge Process
Our approach to air conditioning recharge is methodical and compliant with all F-Gas regulations. We begin with a comprehensive diagnostic assessment to ascertain the system's condition and identify any potential leaks. If a leak is detected, our engineers will locate and repair it using industry-standard techniques before proceeding with the recharge.
Once any leaks are addressed, the system is evacuated using a vacuum pump to remove any residual moisture and non-condensable gases, which can severely impair performance. The correct type and precise amount of refrigerant, as specified by the manufacturer, is then weighed and charged into the system. Finally, we perform thorough operational checks to confirm optimal performance and efficiency.
- Detailed system inspection and leak detection.
- Repair of any identified leaks.
- System evacuation to remove contaminants.
- Precise measurement and charging of the correct refrigerant type.
- Post-recharge performance testing and verification.
Types of Refrigerants We Work With
The air conditioning industry has seen a shift in refrigerant types due to environmental concerns and evolving regulations. We are equipped and certified to handle a variety of refrigerants commonly found in commercial and industrial AC systems. Our engineers stay updated with the latest F-Gas requirements and safe handling procedures for all approved refrigerant types.
This includes older refrigerants where appropriate, and newer, more environmentally friendly alternatives. We can advise on refrigerant conversions or upgrades if your existing system is using a phased-out refrigerant and a suitable replacement or system modification is feasible.
- R-410A: A common HFC refrigerant with good efficiency.
- R-32: A newer, lower GWP (Global Warming Potential) alternative for some systems.
- Other F-gases and permitted refrigerants as per current regulations.

Frequently asked questions
What is air conditioning refrigerant?
Refrigerant is a chemical compound that absorbs and releases heat as it changes between liquid and gas states within an air conditioning system. It is essential for the cooling process, transferring heat from your indoor space to the outside environment.
How often should my AC system be recharged?
A properly installed and maintained air conditioning system in good condition should not require frequent refrigerant recharges. If your system is losing refrigerant, it typically indicates a leak that needs to be identified and repaired before a recharge is performed. Recharges are usually only necessary after leak repairs or component replacements.
Is a refrigerant recharge part of routine AC maintenance?
No, a refrigerant recharge is generally not a routine maintenance item unless a leak has been detected and repaired. Regular maintenance involves cleaning coils, checking electrical connections, and inspecting components, but does not usually include adding refrigerant unless specifically required due to a problem.
What are the signs that my AC system needs a recharge?
Common signs include reduced cooling performance (the air isn't as cold as it used to be), the unit running for longer periods to achieve temperature, ice accumulation on the outdoor unit's lines or indoor evaporator coil, or a hissing sound indicating a potential leak.
What happens if a leak is found during the recharge process?
If a leak is found, our F-Gas certified engineers will first locate and repair it using appropriate methods. It is crucial to fix the leak before recharging the system, as simply adding more refrigerant without addressing the leak would be a temporary solution that wastes refrigerant and could cause further issues.
