4 air conditioners is about 1600 watts. As long as you pay your bill on time and dont cause any trouble with neighbors keep your grass cut and eliminate smell you should be fine.
Just make sure to fluoro out the house bulbs and keep all extra electrical appliances off, rule of thumb...1000 watts per bedroom. Work your light consumption up slowly...don't just throw all 1600 watts up. Maybe do like one light for a month and then add another. You should be fine.
