For new installations we supply and fit Worcester Bosch air conditioning systems — A+++ energy rated, whisper quiet at ~20dB, and built to last well over a decade with annual servicing. Bosch units deliver the same engineering quality and reliability the brand has stood for since 1886, and they're the system we'd install in our own homes.
Every Bosch installation we carry out comes with a 5-year guarantee covering parts and labour — not just parts. If anything fails within 5 years, we return and fix it at no cost to you. We also service and repair all other major brands including Daikin, Mitsubishi, Panasonic, LG and Fujitsu — so whatever system you have, we cover it.
