    Mini-Split & Small VENTILATING Dehumidifier would be appropriate.

    That's why I asked.

    We lived in Houston for several years, it has all of the worse but almost perfect for slightly undersized. During the day plenty of run time to dehumidify and once the sun goes down now perfect operating conditions.

    I really didn't want a mini split and there is really no where to put the inside unit. Originally, I wanted a dehumidifier with all this, and was also going to get the big 4-5" pleated filter, allergies, asthma. Mini splits don't really have great filtration, more like the old window AC filtration, and from what I have researched require cleaning, probably more often than not in our mold driven climate. This room is going to end up essentials the 3 bedroom in this house, not an occasionally used space.

    Manufacturers of gas furnaces, stopped production of furnaces with PSC motors on 3 July 2019, but they can be found at distributors collecting dust but for sale while inventories last.

    So is the cased coil you referenced already installed at the residence?

    As doubt it’s would be a match, ( the full manufacturers warranty thing ) and it looks like the S8X1 handles up to a 2 ton coil, your is a 3 ton I believe.

    Except from Trane warranty, the last paragraph talks about AHRI equipment to receive the maximum manufacturers warranty.

    So you know the humidity. I find the worst for climate control, is when the temperature drops enough that the AC doesn't run, but the humidity is so high. So you turn the AC temp down and freeze, if you don't you are clammy to dripping wet. I was thinking the variable speed, of the blower and/or condenser would help with that, Not sure I completely have the grasp of it all.

    A ducted Mini can have a 4" pleated filter adapted. Gives you the variable speed capability that Trane wont. Dead quite!

    1 example There are several out there

    Here is what is listed on the unit in the attic. There is nothing installed outside.
    Model no. 4TXCB003DS3HCAA
    Serial no. 201123DJ5G
    mfg 3/2020
    suitable for Mobile use
    Design PSI 480

    I think this does have the EMC blower.

    Is the coil you list just up in the attic, laying around or is it hooked to the ductwork? If it’s hooked up, whomever has the job of installing the HVAC, are they going to wing it with the outdoor unit and furnace or is there model numbers they propose.

    That coil looks to handle anywhere from a 1.5 ton outdoor unit on up probably up to 3 tons as Trane web-site says that coil is rated from 18,000 BTU-36000 BTU ton if I’m reading it correctly.

    Post 73- “ I think this does have the EMC blower.”

    That coil does not have a motor, it’s jus a sheetmetal box with a coil and drain pan inside it. Its called a cased coil. The letter designation are ECM for the motor.

    I don't know how to add a picture that I had taken. There is duct work hooked up but not connected to the ceiling outlets. Some is laying on the floor, which if I understand correctly should be suspended, probably this has not been done yet, maybe.

    Ha, ha, ha...

    Yeah... being formerly from Houston... I know the climate down there better than I want to remember...

    Houston is a good climate for a HP system... the winters RARELY get cold enough for a small strip to handle... and the summers are literally brutal!!!

    I would suggest: get a qualified heating and AC guy out to look at it...
    Remember as noted above: the HVAC guy works for YOU, not for the GC!
    Ask your friends/family for a referral of someone they TRUST!!!

    If I was down there, I would come by... however do not have a Texas license....
    While we are on the subject of license... do NOT allow anyone without credentials to even come out...

    Now to finish reading the thread...

    Yes, and yes...

    Strip heat (KW rated) is the backup heat... needed when outdoor temps go below freezing.
    Yes... a HP is an AC that heats...
    And yes... Houston is BRUTAL... and it is not even summer yet...

    What part of the metro city area do you live in... I used to be in Spring Valley, off I-10 west
