[Shop-talk] Window a/c unit for the garage

[Jorge Garcia]

I am looking for a window/though the wall a/c unit to cool and heat my garage. Based on an online calculator looks like I will need a 18000BTU unit, minimum, to cool my 23x33x11 garage. Consumer Reports had a report on just such units but the largest was 12000BTU. Their winner was LG but since I require a larger unit I don't know if their brand recommendation still applies. 
Do any of you guys have any experience with this type of a/c units (actually heat pumps). Do you recommend any brand(s) in particular? Any comments suggestions would be appreciated.
