FurnaceCompare.com is an independent site where consumers can post reviews of heating and cooling products that they have purchased. While reviews can extend back over several years, this page lists the ones sold in 2016 that have rated tops with users thus far (though some of these ratings include reviews left in 2015 as well). All reviews -- which vary in length from a few lines to detailed descriptions of pros and cons -- can be accessed elsewhere on the site.
