does anyone know of a manufacturer that makes a three ton, 115 volt air handler?
Ducted, straight cooling.
thanks to all

    Trane makes a modular blower that’s 115v designed to replace a gas furnace. You’d have to add the evaporator coil with it.

    If you have 120 volt you can get 240 off the same cable if you put in a two-pole breaker.

    If it is on its own circuit as it should be.

    First Co air handlers are all 115 volt.

    Thanks to all that responded. I decided to just go with a 240 volt air handler as I think it would be easier to change the breaker and run a dedicated ground to from the panel, that if they did not run 12/2 mc cable and a ground is needed. Just as EBEBRATT-Ed mentioned. Yes I hope it is a dedicated circuit, the existing air handler has been there since the building was built so it should have it's own circuit

    Well, you will find out when you power the 12-2 MC with 240 V if some handyman tapped an outlet for your expensive entertainment center off that circuit.   Is there a condensate pump on an outlet near the AHU?  That is something I would check and add a fused disconnect with the rewire from that dedicated circuit to the grounded neutral you are adding.   I'm not sure if that is up to code but you need a separate fuse or breaker for that outlet that will trip if the 120V. Item plugged into that outlet has an over current event.

    After you make that expensive repair and you still have the same problem, What will you check next?

    i'd be way more concerned about motors or appliances on that circuit. most consumer electronics have had power supplies that will work on 90v-250v for about 30 years.

    I don’t know of many appliances that work well on that range of voltages!

    Whatever they ran for a cable is more likely to have a ground than not. Romex, BX and MC all have a ground. At least they have since air conditioning became popular,

    If you do run 12/2 with ground converted to 240 VAC, don't forget to mark the white wire with red tape to indicate that it is hot!
