F-Gas Certified Air
Conditioning Servicing

Keep your air conditioning system compliant, efficient, and reliable with professional servicing from an F-Gas certified engineer — documentation included.

REFCOM registered. F-Gas certified. All domestic and commercial systems serviced.

F-Gas certified air conditioning servicing is the professional maintenance of air conditioning systems in compliance with the F-Gas Regulation (EU 517/2014, retained in UK law). These regulations require that refrigerant-containing systems are serviced, leak-tested, and maintained by certified engineers — and that records are kept for each system.

This service is for businesses and homeowners with installed air conditioning systems that require annual maintenance to maintain efficiency, comply with regulations, and protect manufacturer warranties. It applies to all refrigerant-based systems including split units, multi-splits, VRF/VRV, and portable systems containing more than the minimum charge threshold.

During a service, we clean filters and coils, check refrigerant charge and pressures, test for leaks, inspect electrical connections, verify drainage, and calibrate controls. Systems containing 5 tonnes CO2 equivalent or more of refrigerant are subject to mandatory leak checking intervals under F-Gas regulations.

We are REFCOM registered and hold the appropriate Category 1 F-Gas certification for installation, maintenance, servicing, recovery, and leak checking of all fluorinated greenhouse gas equipment.

Operating an air conditioning system containing fluorinated refrigerant without proper maintenance records is a regulatory offence. The Environment Agency enforces F-Gas regulations in England, and non-compliance can result in enforcement notices, fines, and system decommissioning orders.

An unserviced air conditioning system loses efficiency progressively. Dirty filters restrict airflow, reducing cooling capacity by up to 15%. Dirty coils reduce heat transfer. Low refrigerant charge from an undetected leak forces the compressor to work harder, increasing energy consumption and accelerating wear.

Refrigerant leaks are both an environmental and financial problem. Replacing lost refrigerant is increasingly expensive as production quotas under the F-Gas phase-down drive prices higher. A small leak detected early costs a fraction of a full recharge after the system fails.

Many businesses do not realise they are responsible for F-Gas compliance on their premises. If an inspector visits and finds no maintenance records or evidence of leak checking, the responsibility falls on the system operator — regardless of who installed or services the equipment.

F-Gas regulations classify systems by their CO2 equivalent charge. Systems containing less than 5 tonnes CO2e require servicing by a certified engineer but are not subject to mandatory leak check intervals. Systems containing 5–50 tonnes CO2e require annual leak checks. Systems above 50 tonnes CO2e require six-monthly checks. We calculate the CO2e for each system based on the refrigerant type and charge amount.

Common refrigerants in air conditioning systems include R410A (GWP 2088), R32 (GWP 675), and R407C (GWP 1774). As the F-Gas phase-down progresses, the availability and cost of high-GWP refrigerants like R410A is increasing. We advise on the long-term implications for systems using these refrigerants.

Leak testing is performed using calibrated electronic refrigerant detectors sensitive to the specific refrigerant type in use. For suspected leaks that are difficult to locate, we use UV dye injection, soap-bubble testing, or nitrogen pressure testing with electronic pressure logging.

Filter servicing involves removing, cleaning, or replacing the air filters in each indoor unit. In commercial environments with higher dust and particulate loads, filters may need more frequent attention. We advise on optimal replacement intervals based on the operating environment.

Condenser coils on outdoor units accumulate dirt, leaves, and debris that restrict airflow and reduce heat rejection. We clean condenser coils using low-pressure water and approved cleaning agents that do not damage the aluminium fins.

For commercial clients, we offer scheduled maintenance contracts that cover all F-Gas requirements, routine servicing, and provide a single point of contact for compliance documentation. Contracts can include multiple sites and multi-system premises.
