    Mini split outdoor unit perpendicular to house?

    Im working with an HVAC contractor to get a mini split system installed, and Id appreciate a second opinion on the outdoor unit placement.

    Our house is a narrow rowhouse with privacy fences on either side of the backyard.

    Is there any reason not to install the outside unit (a double-height Mitsubishi MXZ-8C48NA) perpendicular to the house, as in the attached sketch?

    The contractor says hes only ever installed them parallel to the house, but Id like to put it alongside the fence to preserve as much space on our patio as possible. (Both configurations conform to Mitsubishis clearance requirements, and both would have the unit about 3 away from the house.)

    Do you want all that heat blowing on you while on the patio?

    Good question. I was under the impression that it doesnt blow too much hot air

    If it becomes a problem, I could add an air guide to blow more toward the yard, I guess.

    Ask for a factory wind baffle to be installed, if one is available. There are requirements on how much clearance you need to discharge air in front of the unit, otherwise you might create an issue.

    Not if you want the unit to operate. The wind baffle will help that if it is made for that unit.
