Mannix were rated highly on their level of customer service, particularly via phone, resulting in a score of 8 out of 10. Their team are friendly, patient and professional and customers are able to speak with an expert who can answer technical questions throughout the customer experience. Having said that their response times to online enquiries are slow regarding quotes, taking more than four days for the initial response and then for the quote to be generated, resulting in a score of 6.5 out of 10. The Mannix review team found the quickest way to obtain a quote was by phone with this company.

Morphett Air is a family run business, and each person in the family is knowledgeable about the air conditioning systems they install. This results in an added personal touch when dealing with this company. The team appear eager to please and to assist customers to find the solution that works for them.

Morphett Air was given a score of 8 out of 10 for their over-the-phone customer interaction, and 7 out of 10 for their email-based customer service. This performance is impressive when compared to the other businesses reviewed, further cementing their spot in our top 5 air conditioning installation companies based in Adelaide.

Morphett Air typically took 48 – 84 hours to acknowledge receipt of an initial email enquiry and the same time frame was taken to respond to quote requests. Our review team classified Morphett Air’s overall response time to customer enquiries as “slow”, when compared to other top 5 local companies.

Some of Mannix’s office locations offer an air conditioning showroom and some locations offer services on the weekend, specifically Saturday mornings. Mueller Services do not offer weekend hours.

In summary both our Mannix and Morphett Air review teams found that these companies provide outstanding and reliable air conditioning installation services in Adelaide and the broader South Australia region. Each offers extensive working experience and technical expertise, with Morphett Air being established in 1973 and Mannix beginning operations in 1966.

Mannix are a well established Adelaide company, with many locations covering a large service are in South Australia and Victoria. It is important to note however that while Mannix offers installations and repair, an affiliated contracting company conducts all of their repairs. They are transparent in making sure special offers are accessible through their company website and Facebook page.

Both companies possesses the air conditioning industry certification of an ARC tick.

Either company would be a great choice for installation with a high level of customer service standards and affordable pricing with the caveat that Morphett Air does not generally install air conditioning systems in apartments. They can however do so if it is a particularly straight forward job, and there is a balcony to place the external unit.
