We're remodeling a 400 sq foot apartment over a detached garage. This will be my home office. My wife doesn't want the expense of a conventional HVAC unit, nor the costs even of a mini-split unit. So I guess I'm now researching good quality window units.
I need something that will both cool and heat. Someone mentioned to me that I need a "heat pump window unit" but I've been unable to find anything like this.
Does this sort of thing exist? If so, what are some brands or models I can look at? Pro's and con's of this sort of thing?
