Air conditioning servicing
that keeps the warranty alive

F-Gas leak checks

Systems are measured by how much refrigerant they hold, converted into tonnes of CO2 equivalent. Once a system reaches 5 tonnes, the operator has to arrange leak checks by a qualified engineer and keep records.

With R32 that 5 tonne line sits at roughly 7.4kg of refrigerant. A home split holds one to two kilos, so no checks are due. A commercial VRF usually sits well over the line, and hermetically sealed units under 10 tonnes are exempt either way.

TM44 inspections

If you own or manage a building with air conditioning over 12kW of effective rated output, an accredited energy assessor has to inspect it at least every five years, with the first inspection within five years of the system going into service.

Four 3.5kW cassettes in an office already cross that threshold. The report goes on the national register and the duty sits with the building owner or the person controlling the system.

We flag systems over the threshold during servicing and track the renewal date so it never creeps up on you.

How warranties actually work

Manufacturer warranties are parts only and run from five to ten years depending on the brand and on the installer's accreditation level with them. Labour is separate and comes from the installer.

• Cover applies to matched indoor and outdoor pairs, not mixed kit
• Refrigerant is treated as a consumable and is never covered
• Annual servicing is a condition, not a suggestion
• We register the warranty for you and send the certificate with the handover pack

We give two years on our own workmanship on top of whatever the manufacturer provides.
