It's time again for the annual Cooling Showcase. For those who are unfamiliar with The NEWS' annual issue, it has traditionally introduced the latest air conditioning units available for the upcoming summer season. The intent is to help contractors prepare for this busy period by doing the research that will help them to distinguish between brands and between different types of equipment, too.

Like last year, this year's Cooling Showcase is split into two parts - commercial and residential.

In this issue, we will focus on the commercial side of the air conditioning industry, while our April 17 issue highlighted new offerings in the residential cooling market. Included in the coverage is feature-specific information about each individual product as submitted by the manufacturers.

Provided on our home page is the Commercial Cooling Products Chart (click on the link under Cooling Showcase), which includes technical facts, such as unit tonnage, refrigerant type, efficiency rating, and cooling capacity. This product feature provides more in-depth information on the features of each individual unit, including the IAQ equipment each unit supports and thermostat and replacement parts compatibility, and also includes technical support information from the manufacturer.

The manufacturers provided all of the data included in the product chart, as well as in this product feature. Therefore, any questions should be directed to them via the contact information provided below.
