    Hi here's my deliema. I have a small mother in law type house on some property. Its 400 sq ft, all electric, 200 amp service, on a slab, outside commercial metal, two 6'x6' double pane windows, two 9 lite insulated steel doors, 8' ceilings, sheetrock on walls and ceiling, wall insulation r11, ceiling r21, small bathroom and cooking area.

    Now I dont want a window air/heat nor am i too fond of a mini split system. I want it to stay all electric, no gas.

    Would this be too small an area to shoehorn a 1.5 regular split system into?

    That sounds perfect since you have a small mother in law.

    I would find a one ton unit such as the outdoor section of a minisplit and hook it up to the smallest indoor air handler I could find. That is if I didn't like mini-splits....which I do.

    robo you really like mini split systems? I cant honestly say Ive ever really seen one nor known anyone that had one. Are they as durable as a regular split system? Maybe im just put off by the smallness of them. Can they take the hot Oklahoma summers and the cold winters as well as a regular spllit system?

    Whats the heat loss? I think with any HP the issue is you only need 1 ton of cooling but 2 tons of heating.
    You may want to suppliment with some electric BB or electric strip. What about a Vertical PTAC? Comes in 12K with electric backup.

    You might want to check out Bard. They make a 1 ton with optional heat strips that mounts on the outside of the wall.

    Mini-splits are great little units. Very quiet and great for dehumidification. If the winters are severe, a couple of auxilliary baseboard heaters is a good recommendation.

    I also like those Bard wall leech units. I saw another brand of those when I was working in Cayman, but I cannot remember the name.

    The Bard looks kind of odd hanging on there to me. Anyone got any other mini split system pic(s) showing inside and outside unit in real world conditions?

    So say I did have a 1.5 ton regular system installed, what would it do? Not dehumidify? Roast your butt out in summer? High elec bills?

    So on these mini splits. Compared to a window heat/cool unit, is the mini split cheaper to operate? Better looking? Quieter?

    ... Interior installation example of sorts:
    Have you ever been to a motel with a veritcal unit installed?

    Which direction are the two large 6'x6' windows facing?

    Your location?
    A/C or Heatpump can not be determined not knowing whether you are in TX, FL, CA, MN or ND.

    OR 1-ton unit (link by Yorkhvac) might be adequate?

    Local Bard rep can show you lots of installations.

    how bout you just get a nice space heater or 2 from walmart and plug them in???? simple and it works

    that way, you could get a mini split and the space heaters would be your backup. that way, noone has to worry about putting furniture against the baseboard heater

    It's a Mother-in-law house.......tell her to leave the fridge open for a/c, and turn the stove on for heat.
