One of the quickest, easiest and most diverse places to find extensive reviews of heat pump brands is online. Heat Pump Guide.com is a strong example, as are Furnace Compare.com, AC Doctor.com and Nester UK, the latter being especially applicable for those shopping in the United Kingdom.
Heat Pump Guide.com offers reviews and consumer generated ratings for some of the industry's leading manufacturers, including but not limited to Lennox, Trane, Carrier, Florida Heat Pumps, Fujitsu and Amana. Ratings are listed in order of the best out of five stars, and the reader can then navigate to more specific reviews. AC Doctor.com reviews offer the reader the SEER value (Seasonal Energy Efficiency Rating), along with the opportunity to peruse specification details. Additionally, AC Doctor contains features whereby the searcher can compare the product to other options, as well as find contractors and possible rebates, too.
Like Heat Pump Guide, Furnace Compare.com also offers consumer reviews for an extremely wide set of manufacturers. The searcher can either refer to simple graphs illustrating user satisfaction with specific pumps, or they can read archived reviews themselves. However, it bears mentioning that while many manufacturers have been subjected to reviews on the site, the actual number of reviews concerning each individual product can be quite limited, with many having one or two responses only. Nesteruk.org offers less reviews per product than the other contributors, but they are well-crafted, professionally voiced reviews that carefully outline the features and performance of each pump in detail.
