Over time, air conditioning systems can experience a natural loss of refrigerant gas, which is crucial for their cooling and heating functions. When your AC unit isn't performing as efficiently as it should, or if you notice a significant drop in its cooling capacity, an AC gas recharge may be necessary. Our REFCOM F-Gas certified engineers are specialists in diagnosing refrigerant issues and safely recharging your system.
A proper AC gas recharge involves more than just topping up the refrigerant; it requires a thorough understanding of the system's operation, identifying any potential leaks, and ensuring the correct type and amount of refrigerant is used. We provide comprehensive AC gas recharge services across London and the M25, ensuring your air conditioning system operates at peak efficiency once again.
Understanding AC Refrigerant and its Importance
Refrigerant, often referred to as AC gas, is the lifeblood of any air conditioning system. It's a chemical compound that circulates within the sealed system, absorbing heat from the indoor air and releasing it outside (or vice versa for heating). This continuous cycle of evaporation and condensation is what enables your AC unit to cool or heat your environment effectively. Without the correct amount of refrigerant, the system cannot transfer heat efficiently, leading to poor performance, increased energy consumption, and potential damage to components.
It's important to note that refrigerant is not 'used up' like fuel; rather, systems are designed to contain a specific charge for their lifetime. A low refrigerant level typically indicates a leak within the system, which must be identified and repaired before a recharge is performed. Simply adding more refrigerant without addressing a leak is a temporary fix that can lead to recurring issues and environmental concerns.
Signs Your AC System Needs a Gas Recharge
Recognising the symptoms of low refrigerant is key to addressing the issue promptly and preventing further problems. If your air conditioning unit is underperforming, it could be due to a lack of refrigerant. Prompt attention can save you from more extensive and costly repairs down the line.
Common indicators that your AC system might require a gas recharge include:
Experiencing any of these issues means your system is not operating optimally and should be inspected by a qualified engineer. Delaying inspection can lead to increased energy bills and potential compressor failure.
- Reduced cooling or heating capacity from the unit
- Air from the vents isn't as cold or warm as it used to be
- The system runs continuously but fails to reach the desired temperature
- Visible ice formation on the outdoor unit's evaporator coils or refrigerant lines
- Hissing or bubbling noises coming from the indoor or outdoor unit
- Higher than usual electricity bills for the same level of usage
Our Professional AC Gas Recharge Process
Our approach to AC gas recharge is meticulous and comprehensive, ensuring the longevity and efficient operation of your air conditioning system. We adhere strictly to F-Gas regulations and best practices, employing only REFCOM certified engineers for all refrigerant handling.
The process typically involves several critical steps to ensure a safe and effective recharge:
This thorough approach not only restores your system's performance but also prolongs its lifespan and ensures compliance with environmental regulations.
- **Leak Detection:** Before any refrigerant is added, our engineers use specialised equipment to detect and locate any leaks within your system. This is a crucial step, as simply recharging a leaking system is a temporary and inefficient solution.
- **Leak Repair:** Once a leak is identified, we will provide options for repairing it to ensure the system is sealed properly. This might involve replacing a faulty component or sealing a compromised joint.
- **Vacuuming the System:** After repairs, the system is evacuated using a vacuum pump. This removes any moisture, air, and contaminants from the refrigerant lines, which are detrimental to system performance and component life.
- **Refrigerant Charging:** Using precision scales and gauges, the correct type and amount of refrigerant (as specified by the manufacturer) is carefully introduced into the system. Overcharging or undercharging can both lead to inefficiencies and potential damage.
- **Performance Testing:** Finally, the system is thoroughly tested to ensure it is operating correctly, cooling or heating effectively, and that there are no new leaks present. Pressures, temperatures, and current draw are checked against manufacturer specifications.
Types of Refrigerants We Handle
The world of refrigerants is diverse, with various types designed for different applications and systems. Environmental regulations have led to the phasing out of some older refrigerants and the adoption of newer, more eco-friendly alternatives. Our engineers are proficient in working with a wide array of refrigerants commonly found in modern and older air conditioning and commercial refrigeration units.
We handle and source refrigerants such as R410A, R32, R407C, and others, ensuring we always use the appropriate and compliant gas for your specific system. Our REFCOM F-Gas certification assures you that we operate legally and responsibly, adhering to all current environmental standards for refrigerant handling and disposal.

Frequently asked questions
How often does an AC system need a gas recharge?
An air conditioning system should ideally never need a gas recharge unless there's a leak. If your system requires a recharge, it indicates a fault, typically a leak in the refrigerant lines or components. Our engineers will always identify and repair any leaks before recharging to ensure a lasting solution.
Is AC gas recharge included in routine servicing?
No, a routine service primarily involves cleaning, inspection, and performance checks. While a service might identify low refrigerant levels, the recharge itself is a separate, more involved process that requires leak detection and repair, and therefore carries an additional charge. We will always inform you if a recharge is needed.
What happens if I don't recharge my AC system when it's low on gas?
Operating an AC system with low refrigerant can lead to several problems: reduced cooling/heating efficiency, increased energy consumption, potential damage to the compressor (which is an expensive component), and overall reduced lifespan of the unit. It's crucial to address low refrigerant levels promptly.
Can I recharge my AC system myself?
No, handling refrigerants requires specialised tools, training, and F-Gas certification. Attempting to recharge an AC system without proper qualifications can be dangerous, harmful to the environment, and may lead to system damage or legal penalties. It is always recommended to use a certified professional.
What is the difference between R410A and R32 refrigerant?
R410A and R32 are both HFC (hydrofluorocarbon) refrigerants used in air conditioning. R32 is considered more environmentally friendly than R410A because it has a lower Global Warming Potential (GWP). Many newer AC systems are designed to use R32 for improved efficiency and reduced environmental impact, though systems are built for one or the other, and they are not interchangeable.
