Aircon refrigerant checks and gas top-ups

Aircon refrigerant circulates in a sealed system; it is not normally used up like fuel. Poor cooling can have several causes, so diagnosis comes before a top-up.

A top-up does not fix a leak

If refrigerant is low, a technician should assess the cause and discuss leak testing and repairs. Adding refrigerant without addressing a leak can leave the problem unresolved. There is no universal schedule requiring every aircon to be topped up every one to three years.

What a technician checks

• Airflow, filter and coil condition, operating symptoms and relevant measurements.
• The equipment's specified refrigerant and signs of leakage.
• Whether repair, evacuation and a measured recharge are needed for that system.

Use the correct refrigerant

R22, R410A and R32 have different equipment and handling requirements. They must not be mixed or treated as interchangeable. R22 is ozone-depleting; R410A has a high global-warming impact. R32 also has environmental and flammability considerations. Refrigerant work should be performed by a suitably trained technician, following equipment requirements.
