Thread: AC Case Coils

  1. #1
    I have a 4 ton blower on my carrier furnace...I'm getting ready to put a Central ac ( goodman ) in. My question is do i use a 3.5 ton coil or a 4 ton coil. Will I see any significant difference between the coils?

    you need to have a load calc done to determine your cooling size, just because you have a four ton blower doesn't mean you need four tons of cooling,put a call in to a contractor so it is done right

    Your contractor will know what coil to match up to what ever size OD unit. After he knows what size A/C your house needs.

    A lot of times we oversize the indoor coil by a half ton. If putting in a 3 1/2 ton condenser, then we install a 4 ton coil. Some manufacturers like Rheem dont even sell a 3 1/2 ton coil. You have the option of changing out the metering device i guess to a little smaller one. But I doubt you'd ever know the difference.

    I doubt seriously

    that a Goodman 3 1/2 ton condenser even puts out 36K of BTUs. Do a load calc then an ARI match your equipment to the load.
