what are dimensions of existing air handler? Both Trane and sister company AmStd have measurements of air handlers on their respective websites. Of course you want an AHRI matching system when you do replace your system.

IMO

I just checked with a tape measure. I got:

21 3/8" wide

23" deep

45" high

10" April aire filter box

11 3/4" bottom plenum mount?

6" top plenum

• top duct.

You should be able to find an air handler that fits without any major reconstruction. For example, the Rheem 3 ton model (RH1P) is 21wx22dx42h.

You should easily be able to find a 2.5 ton heat pump air handler that will fit in your closet. a 17 1/2" wide air handler should be available in Goodman, Amana, and Carrier. You will need to make sure your home is adequately wired to accept at least 10KW electric heat for backup and emergency heat. Easy, Easy! Feel free to visit our website and blog if you need more information. We also have a contact page if I can be of any assistance in selecting your system. IF for some reason, you just can't find a new air handler that will fit, remember your air handler is just a case with a fan and a heat section. As long as the case is good, the rest of it can be replaced very cost effectively. Feel free to visit us at Air and Energy Solutions.

We have a new Carrier air handler/heat pump(variable speed) that measures 21" W X 70 1/2" H X 22" D.. It can be paired with a 2, 2/12 or 3 ton outside condenser,. Also, there is the option to separate the blower unit from the coil box when installed to save space. BTW, we are selling the unit as we had to use a high velocity unit so the unit is brand new. A bargain for someone.

Would you mind telling me what model numbers are?

It is Carrier Model # FV4CNF003. You can message me if you want the owner's manual or any more info. I think one of us has to follow the other to send a message.
