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.
