    Going to have partial coil replacement

    Hi, everyone
    Here is the update of my dealer's resolution.
    The 2007 model was from a local supplier. By admitting the mistake, the supplier will pick up the expense of replacing a newer model so the dealer is willing to come over do the replacement.

    I said partial replacement because the gas furnace is already installed on top of the coil, so the dealer will keep the metal case of the old coil in place and put in the inner parts (spine-fin coil ?) of a 2011 model , by doing this way will make the job a little bit easy. I was told the copper refrigant line will be open again, clean, vacume and solder back and reconnect all pipes.

    When I ask the comfort specialist 2 days ago to have them replace a newer model, he said he has concern about opening up the refrigerant line and re-solderling it. But now his answer is the technician will take care of that.

    So here is my question to you guys : Is that the normal procedure just replace the inner parts when a coil is need to be replaced? Will it cause any harm or side effect to the heat pump or gas furnace?
    (I assume the warranty should not be affected, right?)

    Well, another correction. Now I know the dealer will replace everything inside the comfort coil. (The spine fin coils are totally different parts in side the outdoor unit). The link below shows the diagram of the comfor coil on page 20.

    The sales person told me everything inside that metall cabinet will be replaced.

    Can I have some advice from anyone about this procedure? If it is a normal thing that a technician can handle, I will have peace of mind to wait for the job done.

    Warranty in tact, no problem. Pretty basic to change a matching coil.

    I wouldn't worry about a thing except:

    Is there a large (size of a fist) blue or gray tube, attached in line with the small copper line at the inside coil?
    How about outside of the condenser unit?

    If so, its called a filter drier, and needs to be replaced.

    If the filter drier is inside the outside unit, then no worries.
    "Better tell the sandman to stay away, because we're gonna be workin on this one all night."

    "Dude, you need more than 2 wires to a condenser to run a 2 stage heatpump."

    "Just get it done son."

    There is no any blue (or gray) tube attached with the copper line, neither inside nor outside unit, when the units were installed. The two ends of the copper lines are connected to heat pump and coil unit directly. Is the installation procedure wrong if no filter drier was attached on the copper line? Should I request it to be added when the technician replace the inside coil parts ?

    If it's not visible, then it's inside the condenser, and you can't see it.

    No need to worry, no need to request anthing.
    Everything is ok.

    So a trained HVAC technician should have no problem to replace the uncased coil, right? Well, I can take it easy and relax now.


    My sincere thanks go to all of you who answered my questions and offered help. Have a great labor day weekend

    We refer to this type of coil change out as a slide out slide in and it is common to do it that way on warranty coil replacement not a problem as long as the coils are the same exact size
