Mitsubishi Electric has opened a new sales office near Reigate in Surrey.
The new 6,000sq ft site has also enabled the company to increase its training facilities for air conditioning and heating installers.
Located close to the M25 and M23 motorways, the new office will serve the company's customers in South London and the South of England and replaces the previous office in Orpington.
Territory manager, Steve Warrington, said: 'We now have a fantastic facility which allows us to grow our sales operation to support our customers even more. We can also now offer comprehensive training on all of our commercial air conditioning and heating products, as well as the Ecodan domestic heating range.'
