I wasn't sure where to post this question so I thought I'd put it here. I'm trying to decide how much more insulation to add to my house this summer. My electricity bills seems very high. I've got a heat pump and an ac unit. My bill ranges from a low of $70 in the summer. To a high of $120 in the winter. My house is an Northwest cottage style built in 1943 and is around 900sf. I was wondering if some of you guys wouldn't mind chiming in with what your electric bills are. I'm looking to compare against others and get an idea of wether mine is really high or not too bad.
