I don't have any paperwork on my Trane AH that was installed in 2004. I've always felt like the air filter I was originally left with didn't fit right but never looked into it. Now that i found this site, I thought someone here might be able to tell me what size filter I should be using.
The AH is a TWE049E13 and is matched to a 2TWR2048A1000AFB2 cond.
Anyone know what size? Always feels like I'm stuffing them in there.
