Great service

I ordered my MrCool system from Dave & Carla at Skyway Mini-splits after failing to get a response from a vendor with a much greater profile online. They answered the phone, a big plus right there. They have been very responsive and helpful when I called with questions. As for the MrCool units, they are working well and I am very pleased. The only problem is with the water drainage from the compressor, the drain fitting does not capture it all, I am having to make a pan under the unit to catch the water. This is only a problem because the compressor is located on a wooden porch rather than on concrete or earth.

Thanks Bill. It was a pleasure doing business with you.
