Could I please get some information for what is probably a 1975 Carrier air handler. The model number seems to be 4ES-220-300, and the serial number 43C80696.
Is this a 2, 3, or 4 ton (or somewhere in between :-)? Can my tech still get a blower motor/capacitor for it? When he left this afternoon he said he wasn't sure if he could. There's no end in sight for our 100+ degree weather, so I'd like to be calling around & getting prices for a new air handler while he's looking for a blower motor just in case.
Thank you for your help.
