You'll probably require a new outdoor unit (heat pump) and indoor coil whichever brand you go with since your indoor coil is likely incompatible with anything newer today. The furnace should be fine, as long as it is in good shape and can support (provide adequate airflow for) what you pair it with. The model number on the furnace will be inside the access panels.

Amana's ASZ14 heat pump with matching coil would be a nice option with a lower upfront cost, but Trane (American Standard), Carrier (Bryant), Lennox, and Rheem (Ruud) are worth looking into as well.

Call local reputable firms to get a couple estimates based on your needs, and post back if you can. I would also suggest having your ductwork looked at. Inadequate ductwork will raise utility costs and decrease the performance of any system.

you should find the data plate for the XV90 furnace on the cabinet. pls post mdl number. The XV90 is a very nice VS furnace-92 to 93% eff.

you already have a Trane coil? but no AC or HP existing?

how large is your home?

what is your location?

what stat are you currently using?

Trane has a fossil fuel kit for dual fuel operation or you could use HW VP IAQ stat with outdoor sensor.

since you already have Trane furnace and intend to use, I would not mix brands. Look at a properly sized Trane XL15i or sister company AmStd Heritage 15 HP.

IMO

Thanks for information provided thus far..

I have looked for the model # again and it's simply not there. I have taken the covers of several times now and all I see are warning labels etc...

I know you are limited without the model# but here is additional information on the house:

- 2000 Square Feet
- Located in Indiana
- Thermostat is generic no name, the system is actually zoned so there is one stat up and another down.
- I do have an existing AC unit, it's an XB10.
- Can you tell me if my existing coil could be used with a HP?

I intend on using the honeywell stats but I am not clear whether or not the zone control board will work properly. I believe it's made by Jackson Systems.

Thanks again

The existing coil isn't a rated match in the AHRI directory for any new Trane product today. It may work, but isn't guaranteed to, and may not have a warranty as an approved combination. Moreover, you would want to stick with R-22 refrigerant (which is being phased out) if you kept the old coil since mineral oil cannot mix with the POE oil of R-410A. So, essentially, the coil should be replaced with the new outdoor unit for the best results and options to you. The XL15i is a very nice heat pump as tigerdunes pointed out.

you need a good thermostat for a two stg furnace paired with a heat pump. if Trane, then the 803 stat. I prefer though the HW VP IAQ stat with outdoor sensor. while you can install any mdl HP, my preference would be Trane XL15i, XR15, or AmStd Heritage 15 with matching indoor evap coil.

What size is existing AC condensor?

IMO

Thanks again for the additional information.

Should I be looking at replacing the coil with another entire cased coil or should I be able to just install a new coil in the existing case? I'm just not sure what the norm would be in this case...

I have a local HVAC installer with many years experience to do the work but I will be purchasing the equipment my self. The only Trane/American Standard equipment I can find thus far is an American Standard Allegiance model # 4A7A5036E1000A. I haven't found a source for the coil yet or any "Trane" branded equipment so I think the XL15 or XR15 aren't an option. Any other ideas?

Thanks

Bubba

American Standard Allegiance model #4A7A5036E1000A

the model listed above and in your last post is an AmStd Allegiance AC condenser, not the Heritage 15 HP condenser.

American Standard or Trane will be fine but you will need a new matching cased evap coil with new refrigerant lineset.

I don't like mixing brands but that may be a consideration.

I also have an XV90 furnace and will check on location of data plate.
