4TEE3D has the AccuClean

4TEE3F does not

Ah, 4A7Z is a condensor & not a HP.

They're not gonna show everything on the site. Elsewise no one would call their contractor.

Guess I am really having trouble making sense of the website.

It says that a 4TEE3F31 has intergrated interior AccuClean filtering. So I was guessing it was an option for the exterior of a 3D31?

When you go to Specs for Heritage 20's in 2 tons it only list the 4A6Z0024.
No mention of the 4A7Z0024 & what the difference may be.

I understand the 16 & 20 models have different SEER ratings.

4TEE air handler already has the AccuClean integrated into it.

Difference between the Heritage 20 HP models is one has a variable speed condenser fan motor, and the other is single-speed.

American Standard Nomenclature help

Deciding on a replacement 2 Ton Heat Pump system & trying to make sense of the #'s.

In the Heritage 20's want to know difference between 4A7Z0024 and the 4A6Z0024?

Benefit over a Heritage 16 model 4A5H6024A?

For the Air Handler I'm thinking 4TEE3D31 which would allow me to add the AccuClean later if I choose?

thanks,
