    Old G10 replacement

    Old Lennox replacement. Believe that coil of 1/4" line worked as a metering device back in the day?

    No pictures of the outdoor, just a 15 seer 4ton condenser, got dark on me!












    Flame away ha!

    nice work.

    you even took old fat service techs into consideration by lifting it off the floor some.

    bless your heart.

    Why'd you make the return drop smaller?

    I'm in love with your ref piping!
    It's all worthy of the wall! Nice work.

    I wish we had basements or proper mech closets. We have about 6" on either side of the unit in 85% of installs.

    I do that so I can pull air from the side and bottom of the furnace. Does help for the service some though!

    The old return drop was 18x22, out of a 36x8 duct. New is 26 1/2x12. It is still plenty big. 26 1/2" is what fits our filter boxes, so I use that width usually.

    Did you bend an offset in the condensate line from the evaporator? Or is that an optical illusion? If so, how did you do it?

    Yes I did. I do that a lot. Heat, use a heat gun or my mapp torch. It will go limp, then you just hold how you want it while it cools. Works slick.

    I've used a turbo torch to bend 3" pvc for a pool. Never on 3/4". Good idea though. The job looks sweet though.

    One thing, Don't you need a relief piped in the condensate?

    That's a beautiful install. Was it in your own home? We do that kind of work for the average Joe every time.

    Equal transititions, elevating the furnaces (3.5 ton and above), "E-Z flex" filters and line sets run the way you ran yours.

    Very nice. What every homeowner deserves. P.S. Did you get rid of that old gas cock?

    Some people say your stuff gets picked apart and I'm not trying to be that guy.

    But gravity makes a good point and wonder what your thought of positive air pressure in evap condensate against negative pressure in fau?

    The cond line is very short and sweet but condensate from coil in cooling could fill hx in fau?

    Oh and ive got some pictures to get online from this month......so I'm sure there is plenty for me to get beat up over.

    I understand what you are saying. The drain for the furnace comes out in a 1/2" cpvc street 90. It is slid inside the 3/4" pvc 90. There is an air gap around it. So if the drain does back up, it will flow out around that fitting rather than into the furnace. Picking up what I am laying down?

    What about the positive air pressure?

    It will blow out around the fitting? The 2 are not glued or even a tight fit. Never had a drain issue and have done a ton of these the same way. There is a trap inside the furnace on the collector box. No pressure or vacuum there.
