    4 Ton XL16 mated to 5 ton coil?

    I finally made the plunge and had my swamp-coolered house converted to A/C.

    Upon review the warranty information, this is what was installed:

    Furnace: TUD140R9V5K
    Condenser: 4TTX6048B1000B
    Coil: 4TXCD061BC3HCA

    If I'm deciphering these numbers correctly, I have a 4 Ton Condenser mated to a 5 ton coil.

    Is there any problem with this? Location is dry Albuquerque, NM.

    Thanks

    Looks like a matched system on the ARI site.

    You might ask dealer why he oversized coil.

    I really would not be concerned.

    What is your electric rate?

    That's a large furnace even with just 80% AFUE.

    IMO

    Maybe to get the higher seer rating he had to use the larger coil.
    Or he used the larger coil because it matched the furnace size, which is fine if he used a txv, or the correct piston size.

    Thanks for the quick reply tiger.

    That ARI reference sure makes me feel a whole lot better, and yes, GOHVAC it's got a TXV.

    I should have mentioned that I'm at a little over 6,000 feet in elevation. They have to rejet the furnaces and downrate them for the altitude. Perhaps that contributes to the coil upsize also? It's probably still a bit oversized however. I was hoping that it would spend most of it's time on low heat.

    As to electric cost......
    The first 1050 kWh runs 7.9 cents per!
    The next kWh's run 6.8 cents per!
    Taxes and more nickel and dime stuff usually makes my electricty about 9 cents per kWh.

    I only saw about a month of cooling need and I was absolutely delighted that the combo runs on Stage 1 most of the time and is dead quiet.

    Thanks again folks.

    I suspect GOVHVAC is correct about the oversized coil to correctly fit your large furnace.

    With those low electric rates, I would have considered the HP version of the XL16i.

    BTW, what is your cost for nat gas?

    Good Luck!
