CoolCar Air-Conditioning Centre Onehunga is passionate about providing excellence in vehicle air-conditioning and heater repairs, combined with great customer support.

The owners are Miles and Rachel Crellin, who met while Miles was on his Overseas Experience in the UK and working as a motorcycle courier.

They bought Morrison Diesel in Onehunga in 2011, a respected provider of specialist diesel work along with general mechanical services. This business has been operating successfully in Auckland for over 30 years.

In 2013, the couple added specialisation in vehicle air-conditioning and heating to the workshop under the CoolCar name.

Miles has a long association with Coolcar, having worked with a number of the team in the 1980s. Both Miles and Rachel are actively involved in the business.

In an exciting development, the business has relocated over the road to larger premises at 30 Selwyn Street, Onehunga in July 2020.

Morrison Diesel

CoolCar Onehunga and Morrison Diesel are run by the same team from a single location. From our spacious workshop in central Onehunga we offer complete automotive repair services for cars, vans, 4x4s, light trucks and campervans.

While we are known for specialist diesel work, we also service many petrol vehicles. Morrison is a trusted provider of fleet servicing for local businesses and has a growing reputation for campervan and motorhome repairs.

We combine quality and expertise with friendly service – please call us on 09 6343989 or visit our website for further information.
