Needing advice....I just had a klimaire mini split installed.room is 19x16 ft.it's a barn that was converted into an apartment. tin roof and sides. solid 1x4 walls and floor,then paneling and with insulation Mini split is 12k .room is not staying cool. Room has insulation. Should a12k be keeping this room cool? Not sure what other info you need...it's installed. By measurements that came with it.should I call someone else to come check it..besides the guy that installed it? Or do you feel it's working the way it should...? Outside air. In 90s I can set it on 70 and it stays about 75/80 degrees...gets as hi as 87...I have now put an 8k window unit in andi will put it on 70 and it cools it to 70 I have now turned split of, and 8k window unit is keeping it at 71 which is what I have it set on

My central air system is suddenly acting whacky. Thermostat and indoor blower are working as normal, activating and running when the temperature rises above its settings, but the outdoor unit does not activate when it should. I checked breakers and none are tripped. The outdoor motor spins when moved, although not freely (I've never spun it manually before, I don't know how easily it should spin). The outdoor condenser unit is made by Inter City Products and is at least 15 years old. Still, repair is a much better option than replace. We are Yankees who transplanted to Columbia, South Carolina. We have adapted to the culture change (as much as anyone could) but have not ever gotten used to the oppressive heat that comes in late Spring. What other info do you need? Any advice is always appreciated. az in SC
