BEST SOLUTION I WOULD RECOMMEND....INSTALL AIR COND AT THE SAME TIME IMPLEMENT THOSE HEAT REDUCONG METHOD TO REDUCE NATURAL HEAT IN YOUR ROOM

MY EXAMPLE: IN A PARTITION ROOM OF A CONDO WITH A SLIDING DOOR TO BALCONY AS MY WINDOW AND WIND SOURCE... THE HEAT IS UNBEARABLE AT AFTERNOON AND NIGHT IF THERE IS NO RAIN...

MY SOLUTION IS GETTING THOSE PANASONIC 1.0 HP NON INVERTER ECONAVI AIR COND....NEXT STEP IF I HAVE EXTRA CASH I WILL TINT MY SLIDING WINDOW DOOR...SO THE BILLS CAN BE REDUCE WITH THE AIRCOND DONT HAVE TOO WORK AT FULL LOAD TO COOL THE ROOM....
