ContractingBusinesses.com publishes a guide that compares the latest models of air conditioners on its website annually. Its 2015 guide, which features product specifications of more than 40 models of air conditioners, has two sections: one for full-size units and one for smaller mini-split models.
For each unit, the guide features the brand and model name, alongside a small photo and the manufacturer's homepage address. The guide also includes each unit's physical dimensions, its sound output level in decibels, its compressor type and its efficiency rating. Finally, the section on special features explains some less common attributes of each unit, such as a turbo mode setting or motion sensor technology.
