Hitachi Air Conditioning is the consumer site for Hitachi air conditioning in Australia. It was originally built to give an interim consumer web presence for the brand when Temperzone Australia took over distribution from Hitachi in 2009.

The temporary site was completely re-built in mid 2010 as part of Temperzones expanded consumer marketing program. The site was entirely re-designed and re-written around the the dual goals of presenting the entire product range and allowing consumers easy and direct access to Temperzones's national domestic dealer network.

During the rebuild the site was given an extensive SEO development to ensure the best possible search in a very competitive market.

318 Online has managed an aggressive Google Adwords campaign on the site. The campaign used multiple custom landing pages and delivered a nearly 10 times increase in site traffic over 3 months.
