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.
line sets
Easy Pro comes with a 16' pre-charged line set, while 5th Generation E Series includes a 25' pre-charged line set.
Which one to buy?
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.
