the difference between the 5th gen Easy Pro and e series

 5th Generation E Series offers a 5-year parts and 7-year compressor warranty.

 Easy Pro provides a 1-year parts and 2-years compressor warranty.

 Easy Pro offers 9K, 12K, 18K, and 24K BTU options.

 5th Generation E Series offers 12K, 18K, 24K, and 36K BTU options

5th Generation systems generally have higher performance ratings (SEER)  making them more energy efficient.

                                             SEER2

 12K               E Series  23.6      Easy Pro  20.2 

12K                E Series  23.5      Easy Pro  19.5

18K                E Series  22.5      Easy Pro  20

24K                E  Series 22.7      Easy Pro  18.9 

36K                E Series   18

The SEER rating is crucial because it directly relates to the operational cost of the air conditioner. An air conditioner with a higher SEER uses less electricity for the same cooling, saving you money on energy bills.

As of January 1, 2023, the Department of Energy (DOE) will introduce the new SEER2 standard. SEER2 keeps the basic ideas of SEER but improves the testing methods to better match real-life situations.

 Easy Pro comes with a 16' pre-charged line set, while 5th Generation E Series includes a 25' pre-charged line set. 

 If you are wanting a longer warranty, wider operating temperatures if you live in a more extreme climate, and higher efficiency rating, the 5th Generation Series is the better choice despite being more expensive. 

However, if these factors are not top priorities for you, the Easy Pro Series is still a great option.

 Both series qualify for tax and energy rebates and can be installed by yourself.
