I have a 1000 sq ft duplex that I would like to cool down in San Ramon, California during this upcoming Summer. Our area has some occasional 100 degree days, but most of the summer is in the 80's and
90's. Both back bedrooms are the hotest rooms in the house since the sun shines directly on the back side of the home. I was hoping to run one portable A/C in the living room and point it towards both bedrooms, but would it be better to run two separate portable A/C's in both bedroroms during the summer and still have some A/C getting some cool down in the Living Room where I watch TV?In regards to BTU ratings, what's my best solution in regards to keeping cool and not paying an arm and a leg in electricity charges? One A/C with a larger BTU rating or two smaller BTU portable A/C's in both bedrooms?
