Air conditioning regas
Air conditioning regas and recharge
Blowing warm air or icing up? Your air conditioning may be low on refrigerant gas. Our F-Gas certified engineers find the leak, repair it and recharge the system to the manufacturer’s specification.

Signs of low gas
Does your aircon need a regas?
These are the usual signs that a system is short of refrigerant. A pressure check confirms it.
Warm air in cooling mode
The system runs, but the air from the indoor unit is not cold.
Ice on the pipes
Frost on the copper pipes or the outdoor unit is a common sign of low refrigerant.
Longer running times
Rooms take much longer to reach the set temperature, and the bills go up.
Fault codes
Many systems show an error code on the display when the pressures are too low.
Done properly
Why we don’t just top up the gas
Air conditioning is a sealed circuit, so if the gas is low there is a leak somewhere. A top-up without a repair only lasts until the gas escapes again, and the F-Gas rules require a leak to be repaired once it is found. So every regas we do follows the same steps.
✓
Pressure and leak test to find where the gas is escaping
✓
Repair of the leak, often at a pipe joint or flare connection
✓
Nitrogen pressure test to prove the repair holds
✓
Vacuum to remove air and moisture from the pipework
✓
Recharge by weight with the correct refrigerant, such as R32 or R410A
✓
Performance check and a record of the work for your F-Gas log
How it works
How an air conditioning regas works
01
Tell us about the problem
Send the make and model and a photo of the indoor and outdoor units.
02
Leak test
We check the pressures and find the leak with an electronic detector or a pressure test.
03
Repair and recharge
We fix the leak, pull a vacuum and recharge with the right amount of refrigerant.
04
Test and record
We check that the system cools and heats properly and record the work for your F-Gas records.
FAQ
Regas questions
How much does an air conditioning regas cost?
It depends on the refrigerant, how much gas the system needs and what it takes to find and fix the leak. We give you a price after the leak test, before any repair or recharge work.
How do I know if my aircon needs regassing?
Warm air in cooling mode, ice on the pipes, longer running times or a fault code are the usual signs. A pressure check confirms it.
Can you just top up the gas?
Not without finding the leak first. A sealed system only loses gas through a leak, and the F-Gas rules require a leak to be repaired once it is found. A top-up on its own means the gas escapes again.
Who is allowed to regas air conditioning?
Only F-Gas certified engineers working for a certified company can handle refrigerant. It is always worth asking to see the certificate.
How long does a regas take?
Most home systems take a few hours, including the leak test, vacuum and recharge. Larger commercial systems can take longer.
Do you regas car air conditioning?
No. We work on fixed air conditioning systems in homes and businesses. For a car, please contact a garage.
