Air Conditioning - Wall/portable heat pump for AC/heat in the Garage?

I would like to heat and cool my 1.5 car garage (about 150 sqft with high ceilings) and turn it into a woodshop. Year round climate control is the goal for the sake of the tools and rough lumber storage. We live in Kansas City, and the outside temp goes from sub-zero to the 90's.

Would a room heat pump like this one be the way to go?

I can accept adding a small supplemental electric heater for those extra cold days, but I want to make sure there would be enough cooling to make the workshop tolerable in the summer.

Thanks in advance,

They do OK.. I just have not hear alot of good things about these type of set up.

With the exhaust hose blowing outside, that air lost has to be made up some now.. So you will pull in the hot air back into the garage.

You could get a built in pack unit in the walls like you find at hotels.

Do the hotel-type not have an outside vent? How well do they cool and dehumidify? Do they have a drip pan that needs to be emptied?

How reliable are the square footage ratings these products give themselves?

The hotel type unit goes into the wall, and has it's own venting on the backside (Outside), and no drain pan to worry about.. These unit can get expesive..

have you looked at wall units? They do make wall unit that are heat pump.. Most likely have to order them.

you might want to check into a mini split system, they work great and are afordable

Jay,

I'm a little new at picking the right type of unit, so please bear with me.

Does a wall unit also vent to the outside? If so, does it have the same replacement air problem as a portable room unit?

We had split-type units in our wood huts in Afghanistan in 2005 and they were terrible. I still had to zip my sleeping back over my head in the winter. Maybe it was rated a too low for the space.

Perhaps my question should be, what's the best method to A/C and heat the garage workshop. Here's what I've got:

The space is 260 square feet with 12-foot ceilings, no windows, one small garage door and poor insulation (I plan to blow insulation behind the drywall and put foam panels on the garage door sections). Our temp range in Kansas City is below freezing (at times) in the winter to high 90's in the summer. I would prefer a portable or easily removable unit, because if we move I could take it with me. I don't wearing flannel in the winter with a small portable heater, but I want to have AC to cool the garage enough so I’ll actually want to spend a few hours in there during the summer. I want the garage temp kept within a reasonable temp range when I’m not there so the woodworking tools stay rust-free and stored wood doesn’t warp and split. There are no windows, but a simple wall divides the two-car garage into two rooms, so I could cut a hole for a window AC unit that would vent into the other side of the garage (cheap perhaps, but not an ideal solution). I do have a gas line in the garage, but now you're talking installation charges for a heater. I'd love the keep the budget around 500-600 bucks, but I'll go higher for the right unit. A unit that gives both heat and cool seems nice and simple, but again, I’m new at this. Any and all advice would be appreciated.

Thanks in advance,
Lee

The wall unit needs go though the wall going outside. So no, it's not going to pull air out of the area like a portable unit does.

As long it's sized right, it shouldn't be a problem.
