Had units installed. Works great. Temps in low 30s so far and no issues with it keeping up.

I have a 3 car garage man cave of 660sq ft with 8 ceiling ft high. Its fully insulated even the garage doors too. I live in Clovis California in zone 9b I think. I been looking at the DuctlessAire 12000-BTU 230-Volt 22 SEER 600-sq Smart Ductless Mini Split Air Conditioner and Heater with 25-ft Installation Kit for $1052 My garage is fully insulated even the garage doors. WIll this work even though it says only for 600sq ft? Or should I get the 18000-BTU 230-Volt 21 SEER 900-sq Smart Ductless Mini Split Air Conditioner and Heater with 25-ft Installation Kit? This one is for 900sq ft but I was reading that if I get an overzsize minisplit it won't work that good?? This one is $1500. Thank u

Looking at install videos, since I won’t be using the full 25’,I don’t see what to do with the remaining line. I live in a winter climate , would the line freeze if I only coil it behind the unit ?

Question for 18,000 btu condenser which has 3/8 and 1/4” fittings. I bought the 18,000 condenser and the 12,000 btu indoor handler and 9,000 indoor handler. The 12,000 has 1/2” and 3/8” lines. Do I need an adapter to fit the 12,000 btu unit to outdoor condenser? Which do you recommend?

Hello, our multi-zone condensers come with adapters, so they will be able to hook up both size heads.
