Refrigerant gas is a key element in the smooth operation of air conditioning systems. Over time, the gas in your aircon system can deplete. When this happens, the performance will be impacted and it can place an extra stress on the system, leading to premature component failure.
How do I know if my aircon needs regassing and what is the process for rectifying the issue?
How do I know if my aircon is low on gas?
There are a number of signs that could indicate your air conditioning system is running low on gas:
If your aircon performance appears to be reduced and is no longer as cold as it used to be, this may be due to refrigerant levels falling low. Refrigerant gas is used to cool the air that passes through the system, and any drop can impact the performance of your system.
If your aircon is making a bubbling or hissing sound, it can indicate that there is a refrigerant leak. These noises will often occur when gas is escaping from small cracks or other faults in the system.
When refrigerant levels are low, frost or ice can form on the pipes or evaporator coils. This is a clear indicator of an issue that needs investigating.
Musty or chemical smells from your aircon are not always a sign of low refrigerant levels but they do indicate that your system is potentially malfunctioning and needs attention.
How can I check my aircon’s gas?
First, check for any visible signs of damage or leaks in the aircon system. Damp patches, frost build-up, and oily residue near connections and pipes can all be indicative of a leak in the system. A thermometer can be used to compare the temperature of the air blowing out of the vents with the air that enters the system. If the difference is less than 10°C, then it may mean that the system is low on gas.
Pressure gauges can be used to measure refrigerant levels, but these require a good understanding of aircon systems to be used safely.
How often does an air conditioning system need regassing?
Newer aircon systems are more efficient and have been developed to retain gas longer than older models. Home and commercial air conditioning units may need regassing approximately every 2-5 years, depending on usage. Regular maintenance can extend the time between regassing, as well as giving an early indication that regassing is necessary.
Can I regas aircon myself?
In the UK, the handling of refrigerants is regulated under F-Gas regulations. This means that the work can only be carried out by a certified professional. Attempting to regas your system without the correct certification may not only damage the system but could lead to fines.
