    Oh, and one complete bonehead move by the contractor. They cut a truss to get the unit into the attic. Then they "repaired" it with one crummy, beat up 2x4 and 2 nails on each side of the cut.

    Thanks for all the responses. Turns out they brought and used the 1-1/8 soft tubing. I think it was actually less than 50 feet, since they had some extra from the coil. I think they only needed...

    house is almost 3000 square feet, built in 1982, so it's probably close to right-sized.

    My bigger concern is whether it will damage the unit over time by starving it.

    That's why I provided the lift and length of the run. I have the installation manual, but it does not have any run/rise charts.

    I am about to have installed a Lennox XC14-060 (5-ton) installed with a new furnace and coil, along with new lines. The specs and install manual both specify a 1 1/8" suction line.

    The sales guy said both are made in the US. Maybe the 13ACX is made in Mexico? Or the sales guy is wrong?

    The XC14 is the lowest of the mid-tier "Elite" models. The sales guys says the difference is the compressor blanket and the case has grommeted screws and hinged panels, so over time it should stay...

    I found some specs for sound data on the units

    For a 5-ton unit, the 14ACX is 80 dB. The XC14 is 73 dB.

    5 dB is "definitely noticeable," while 10 dB is perceived as TWICE as loud. So a 7 dB...

    Lennox 13ACX, 14ACX or XC14?

    I live in So Cal, almost no humidity, summers in the 90's and occasionally over 100. We don't use our AC all that much, as our nights cool down, we open the house, and let it cool down and close it...

    The repair guy said the repair needed is only about $400 less than a new condenser unit, so it does not make sense to repair it.

    Are there questions I should ask to better assess the...

    Replacement unit advice - So Cal

    My compressor stopped working, and it's decision time. I have a 1980-era furnace that still works, and presumably the coil is that old too. The Carrier outdoor condenser is 10-15 years old, I...

    Thanks. From what I've seen around the house, an incompetent builder seems likely.


    So it would be OK to seal the flue to the metal chimney cap? I was just concerned that it might need that...
