Highest & Good SEER Heat Pump Revealed (+ Most Efficient Heat Pumps)

A person who wants to know about the key performance of heat pumps can read this information which explains the seasonal Energy Efficiency ratio and which is the highest and best SEER heat pump. 

Highest SEER heat pump:

The higher seasonal Energy Efficiency ratio of a heat pump has a rating of 33.1. for example, the Fujitsu AOUG09LZAS1, and the Mitsubishi MSZ-FS DELUXE have delivered the highest SEER heat pump.


The following table is based on the research done on 2126 most energy-efficient heat pumps and the table shows the list of the top 10 highest SEER heat pumps According to the rating.

The mentioned above heat pumps do provide heating and cooling functionality and are also awarded energy star’s most efficient label. If a person sees the cost, the cost of a heat pump is more with its efficiency ratio. the most efficient heat pumps can be checked from here.

Heat pump SEER:

  • The SEER refers to the Seasonal Energy Efficiency ratio which is the key performance Metric in a heat pump with the help that it performs the cooling functionalities. The ratio means that the total heat removed in the cooling process is divided by the energy consumed. The ratio obtained shows the cooling efficiency of the heat pumps. 
  • The higher the seasonal Energy Efficiency ratio (SEER) will be of a heat pump, the more efficient it will be for removing heat from the air. A person who wants to buy a heat pump should consider both the factors that are (SEER)seasonal Energy Efficiency ratio and HSPF heating seasonal performance factor study in more detail. 
  • A person who is buying a heat pump which does heating and cooling both are more cause effective and eco friendly. Because after buying a heat pump there is no requirement for buying, produce, and transport heat pumps that perform a separate function of heating or cooling.
  • There are many situations or locations when a person considers cooling efficiency more important than heating efficiency and vice versa. It all depends upon the customer’s climate condition and many more. In that condition, they can buy a heat pump that performs the SEER and HSPF separately. 

Which rating is considered a good SEER rating for a heat pump?

  • A heat pump that has a good SEER rating that changes from 14 to 17.9.
  • The best range of the heat pump is considered from 18 to 31.1.
  • A heat pump has a poor seasonal Energy Efficiency Ratio (SEER) which is less than 14. For example, DOE has a poor rating for heat pump cooling efficiency of 14.
  • There are many sweet bums that have achieved the energy star more efficiently, label those heat pumps that are the most energy efficient in the market and have these seasonal Energy Efficiency ratios (SEER)which range from 18 to 33.1 which is considered best range.
  • The heat pumps which have the SEER ratio between the poor and best range of those heat pumps are considered the good heat pumps having a SEER that ranges from 14 to 17.9.

The following table explains the heat pump, SEER. categories with the seasonal Energy Efficiency ratio rating. 

SEER categorySEER range
PoorLess than 14
Best 18 and higher.

What is the best SEER rating for a heat pump?

It is necessary to buy a heat pump with the best rating because buying a heat pump that is underpowered or overpowered will be useless and a waste of money. So the heat pump which does have the best seer rating is the highest rating considered for all the units and the room size. A person should choose a heat pump appropriately for heating or cooling functionality according to their needs.

The following are some steps that can be used to choose the most efficient heat pump:

  • Choose according to the area as a person first simply can measure the length and width of the room and then multiply them both together it will help them to get the area size and according to which they can choose the heat pump.
  • By getting the square foot of the room size they can identify how much efficient the heat pump they require to cool or heat the room is.
  • Should buy a heat pump that has an appropriate seasonal Energy Efficiency (SEER)ratio or heating seasonal performance factor. As these are the key performance factors in the heat pump which show the efficiency of the appliances. 


From the above information, we can conclude that a heat pump with SEER has the highest rating of 33.1. And the highest top 10 Seer heat pumps do have a rating that ranges from 24.5 and more. It has explained the heat pump which does have a poor and good SEER rating. 


What is the most reliable heat pump brand? 

The most reliable heat pump brands are goodman, carrier, Ruud, Trane, Rheem, Lennox, etc. 

Is it worth it to buy or change 14 SEER to 16 SEER?

A person who does use 14 SEER spends $100 almost every day to cool the room but after upgrading they would save $13 on their monthly bill as the 16 SEER unit are approximately 13% more efficient than 14 SEER
