It's spitting ice crystals when turned on, and is very noisy.

I'm in a similar situation with a physical neccessity for a/c, year round, even though I live in temperate New Jersey. My husband is an A/C / Refrigeration tech & here's some things you can try to fix your Haier A/C.
1.) Make sure you keep the area where the filter is clean, if you aren't using a filter, you are clogging the air flow much quicker, which can lead to freeze ups.
2.) Due to how shoddy things are made now-a-days & with the storm coming through, you may have a conked out compressor or may have a small refrigeration leak, which can also cause freeze ups.
3.) Make darned sure that the unit is level, if you find it is not, leave your unit off for at least 24 hours for the refrigeration gas & oil in the system to level off.
Sadly, I do not know the model or type of Haier A/C you have & as I'd mentioned, things are no longer made to last like they once were & to get 3 years from a newer model is likely to be the best you can hope for. Haier is fairly decent with wanting to keep up customer morale & if it's a newer unit (younger than 18 months), they may help you to repair it for free or low cost. Good luck with that!
