Do I Need An Electric Blanket?

The townhouse that we move in don't have any air con. Lucky us that we live at the top of the hill so the breeze is in and out of the townhouse all the time. We have 4 ceiling fans in the property but we are still planning to buy a portable air con. It is so funny to think that last year during this month we were in a very cold place with our electric blanket to warm us up and now this year we are looking for an air con to cool us down. But no regrets I am liking it here.
