Oceanair, one of Panasonic's largest heating and cooling distributors, has relocated its Nottinghamshire showroom from Kirkby in Ashfield and opened a new showroom in Mansfield.
The move is part of a major investment to boost its facilities for customers.
Oceanair's other office has also relocated from Horsham to Crawley.
The new Mansfield showroom displays the latest air conditioning and heat pump equipment from Panasonic, including a fully-operating Aquarea heat pump system, and offers an improved and interactive customer experience, the company says.
Both Oceanair offices have facilities for Continuing Professional Development (CPD) seminars. There are plans at Mansfield to install IntesisHome software for smart phones and tablet computers, which is already proving successful in Crawley.
