It’s time once again for the annual Cooling Showcase. The NEWS’ annual issue has traditionally introduced the latest cooling 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.

Like last year, this year’s Cooling Showcase is split into two parts — commercial and residential. This issue focuses on the commercial side of the air conditioning industry, while the April 15 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.

The product chart includes technical facts, such as unit tonnage, refrigerant type, efficiency rating, and cooling capacity. The photo feature below provides more in-depth information on the features of each individual unit and also includes technical support information from the manufacturer. The manufacturers provided all of the data included in the product grid, as well as in the photo feature. Therefore, any questions should be directed to them via the contact information provided in the photo feature section.
