This appears to be a 5 ton 14XLi Trane Heat Pump R-410a refrigerant. This is a single stg model and has been a reliable workhorse in the Trane line of HPs. This particular model is being phased out. You will need a matching var spd air handler. And if humidity is a concern for your area, forget the poor Trane stats and go for a Honeywell Vision Pro IAQ. You might want to consider a Trane XL15i HP.

Thanks for the information, tigerdunes. The fact that this model is being phased out - would that be a reason for us to not install this one? (We don't have any humidity issues).

i have the 3.5 ton version of this unit, and it works great. the reason Trane is phasing it out is the same reason Ford, Chevy and all teh other manufacturers change lines every few years, to present new products to teh market. the units WILL be supported for years to come, so don't worry about that.

Thanks, David, that was what I was worried about. You eased my mind

Nothing wrong with the Trane 14XLi. It is a solid and reliable HP. The 15XLi is just a little more efficient. You will need a matching var spd air handler to maximize the efficiency capability of the HP. That's alot of BTUs-recommend you have a load calculation performed and get it in writing.

Do you mind saying area of country you live?

I live in north Idaho so we get some "good" winter weather (especially this winter). Our home is being built and the bottom floor is about 2900 sq ft (vaulted great room ceiling) with about a 300 sq ft loft.

The 4TWX4060 heat pump matched with a 4TEED365 air handler is 60,000 btu cooling (a full 5 tons), 10.2 EER, 13 SEER, 57,000 btu heating at 47F, 9 HSPF. ARI# 1236555. The cooling btus are solid and so is the HSPF (cost to run heat pump in heating mode). The EER (cost to run heat pump in cooling mode) is very weak. EER of 11 is OK, 12 is excellent.

The same heat pump matched with a 4TXfH063 air handler w/furnace is 59,000 btu cooling, 10.7 EER, 13 SEER, 55.5 btu heating at 47F, 8.75 HSPF. ARI# 677784.

If the XL14i model is being discontinued, I would try for a nice discount.

Best to you.

Thanks, Gary. I think I will try for a discount.

hi-
I guess this is a good time to ask- and humidity is an issue!
I live in Charlotte,NC and need a new HP- for a small zone in my 30 year old house (other units are gas furnaces). What units do you recommend- reliability is key for me.
Thanks
