Heat Pump Ratings, A Repairman Reviews The Brands...
With our heat pump ratings you can cut through the sales hype and find value. It really is like taking a repairman with you while you shop. We have done the research and ranked the brands using our years of experience in the hvac industry.
These heat pump ratings are for air source, ducted units. We have separated them into three categories. The first is basic heat pumps. These are the least expensive models but they also have the least amount of features. Their seer rating is at least 13. That is the minimum allowed in the U.S.A.
The second category is premium heat pumps. These units have a seer rating of at least 15 but their price is higher.
The final category is ultimate heat pumps. These units have a seer of at least 18 and have the most added features.
Their price is also usually the highest.
If you do not have an air duct system, you can use our ductless ac ratings page. For systems that use water to transfer the heat, you can check our air source heat pump reviews page.
If you would like to compare ground source units, you can use our
geothermal ratings page to assist you in your brand selection.
For your convenience, we have included the web addresses for the manufacturers as well as our comments concerning the advantages/disadvantages of the brand.
If an NA appears in the place of stars, it means that brand does not have a unit available in that class. As always, more stars equals a higher rating!
