Every year, The NEWS introduces the latest heating equipment that is available for the upcoming winter 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 Heating Showcase is split into two parts — residential and commercial. The residential/light commercial information is published in this issue, and the commercial products will be featured in the Oct. 5 issue. Included in the coverage is feature-specific information about each individual product as submitted by the manufacturers.

The showcase features a product grid, which includes technical facts, such as unit tonnage, refrigerant type, efficiency rating, and cooling capacity. To view and download the product grid, click here.



The accompanying photo feature provides more in-depth information on the features of each individual unit and 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 below.
