    Why not? The XV80 is a two stage variable speed furnace.

    HVACmd,

    Nice job!

    Did they fire off both of the old furnace for heat or were they stagged some how?

    Why not 90%?

    There was only the 5-ton evaporator coil and another blower package in the second cabinet.The Honeywell IAQ allowed for remote monitoring,temperature averaging,true 2-stage operation,and outside temperature humidifier automation.They ruled out the 90 for cosmetic(vent pipe in front of house)reasons.

    That looks great... nice work!

    Did you take any pictures of the air conditioner outside? Is this a R-410A system?

    The duct wrap and elbos are 24x10,there are turning vanes in the drop,spot welded inside,no rivets,no photos of the condenser,it's on a new concrete slab,with sight glass,the Trane cased coil was 2 inches taller and would have kept us from raising the furnace onto the blocks,or no duct canvas connectors which are our companies' standard.A lot of the old homes out this way have restricted ceiling height in the basements.R-22 system with new line-set .They turned down XL16i and XV95.
