Thanks to JLA’s high quality standards carried out by our nationwide network of F-Gas and Refcom Elite-certified engineers, we continue to build a reputation for our commercial air conditioning solutions.
But we’re never content to rest on our laurels, which is why we’re proud to announce that JLA was recently audited by independent experts and now holds Mitsubishi Diamond Quality Partner status – the firm’s highest level of endorsement.
Raising industry standards
Diamond Quality Partner status is reserved for organisations with a commitment to excellence. Mitsubishi Electric’s Partner Programme is designed to uphold the highest standards across the HVAC industry, encompassing the supply of equipment as well as the quality of system design and installation. The Diamond Quality Partner accreditation recognises organisations that consistently deliver superior performance and workmanship.
Only businesses who are dedicated to aligning with a leading manufacturer and capable of meeting stringent criteria are eligible to apply for this prestigious status. This allows the JLA HVAC team meets these standards, which provides confidence to JLA customers across the UK.

Recognised industry-wide for HVAC installation excellence
JLA has supplied, installed and looked after Mitsubishi Electric’s commercial HVAC systems for many years. From the start, we’ve always worked closely with the manufacturer as well as our customers to deliver the best possible results.
Our new Diamond Quality Partner status recognises this commitment to excellence and underlines our ability to meet exacting standards at every step of a project.
What Mitsubishi’s endorsement means for you
Whether we’re upgrading an existing air conditioning system or managing a new commercial HVAC installation from start to finish, Mitsubishi Diamond Quality Partner status means you can be assured of the best possible workmanship and reliable ongoing support.
What’s more, our Diamond Quality Partner status has given us access to new tools that allow our teams to optimise HVAC system design and monitor performance for improved efficiency.
Even better, our new status means we can now offer all HVAC customers a 10-year warranty on Mitsubishi’s air conditioning systems. It’s extra peace of mind that your critical systems are covered.
Enhancing our commercial air conditioning service
The Diamond Quality Partner allows JLA to better support air conditioning customers and provides them with reassurance. Our main range of Mitsubishi air conditioning solutions include both wall mounted and ceiling casette units.
Mitsubishi wall-mounted air conditioning
Wall-mounted systems are a proven solution in commercial environments due to their sleek design, quiet operation, and energy efficiency. These units are mounted high on the wall, so they are ideal for rooms where floor space is limited.
Their compact form factor makes them especially suitable for offices, hotel rooms, and smaller retail spaces.
Mitsubishi ceiling cassette air conditioning systems
Installed flush into the ceiling, these systems deliver 360-degree airflow, ensuring consistent cooling or heating to the specified temperature.
They are ideal for settings like offices, restaurants and gyms where aesthetics are important along with a high performance and reliability. Cassette units also offer ‘i-see’ technology to automatically ‘sense’ room occupancy, ambient body temperature and position.
