The wiring in my house is horrible. When the house was built 11 years ago it seems every room is on 1 breaker. My question is that in my living room I have an air conditioner that keeps tripping the breaker. The breaker is only 15 amps, how would I go about changing it to atleast a 20 amp breaker?. Is this something simple? Can I do this myself. My dining room has a 20 amp breaker in the box and there is only a chandlier in that room, no other electric is used in there. Can I take that breaker out and put it in my living room?
