Premium systems routinely last 12–16 years; budget systems often fail at 5–7.

At a glance

Daikin and Mitsubishi compressors are inverter-driven and rated A+++ in most configurations.

Generic units are typically B-rated, with shorter warranties and limited UK parts availability.

Over a 15-year horizon, premium kit is almost always cheaper on a total-cost-of-ownership basis.
