Try to find a contractor through AC Pro, they sell the same rebaged Midea unit (they call it the z series) as Mr Cools Universal 2. https://www.acpro.com/home https://store.acpro.com/ac-pro-z-series-air-handler-multi-position-3-ton-115-208-230v-17-5-wide-r454b-84228 I use this Yellow Jacket guage set: https://www.amazon.com/dp/B0D4SD25DK If you have your EPA 608, AC Pro will let you set-up an account with them and you can buy refrigerant from them if you want to do a leak test. Unfortunately you do have to be licensed contractor to buy AC units from them, but they will sell you most everything else.
