I have a new room we built underground and used all heavy material no expensive spared. R-30 thickest insulation and foam board over that. Will go Mylar next but my issue is I bought portable ac unit "single hose" I make my own second hose plenum, I am a/c electrician I already knew what to do. I have electrical ran everywhere 6" fresh air from outside pulling into the a/c then out the exhaust with a 1000+ cfm exhaust fan. I have a negative pressure because I have not finished my door hatch/ gasket seal. Is my door not being sears the reason my temperature want pull down under 77? When it's hot outside? I'm not even running a light yet and only pulls down to low 70 at night time. Maybe my ac just under sized. Even tho 9x11x7 high and I bought 12,000 btu ac should pull down a naked room I would think or is it my door hatch lolling in too much air for outside? I can stand on laser by door and a lot of air rushes over me and sucked out the door
