Any experience with heat pumps in the shop?

I am thinking about heating/cooling my 300 sq. foot shop with a split unit heat pump . I have asked one HVAC tech what he though. His response was that it would probably work, may need to clean the inside air handler filter once a week. I am wondering if anyone has a unit in their shop and how it has worked out for them.
 
I have one, it works great. Woodstove for backup/supplemental heat. You do need to clean the prefilter regularly, get the coils professionally cleaned periodically and control the dust level in the air as well as possible

I had a heat pump installed when I built my shop maybe 9-10 years ago. My shop is about 1400 sq ft so my HVAC guy sized a 1.5 ton system with outside and inside components. I built the walls with 2x6s for extra insulation; the heat pump keeps the building as warm or as cool as I want with ducts to the different rooms. The climate here in TN is a somewhat warmer in the winter that when I lived in PA, if that makes a difference. I keep it fairly warm in the summer and somewhat cool in the winter to save energy costs but it's always comfortable. Since I process green wood into blanks, dry, and store wood I really like that it keeps the humidity fairly constant.

I do have to keep the filters clean but have to for the big heat pump at the house too. I use a central dust collector in the shop so the filters don't get clogged with wood dust floating around.

I also have a heat pump. I turn it off when doing something that makes a lot of sawdust to cut down on the frequency of cleaning the filter. Make sure you install a surge protector. I did my own installation and didn’t think about that. Cost me a bundle when we had a brown out!
