I have a small flat and got a power bill for two months and it was over $600. That was during the summer and now it is winter and I heard that heating is like three times the amount that cooling is, so how much is my power bill going to be this time with the heating running each day? I actually haven’t been using the heating much because I am afraid of what the bill might be. I read online that it costs about $3 per hour while you run your heat. So if I ran it four hours a day during the cold months it would add $720 to my bimonthly bill? So that means my power bill would be about $1000 if I ran my central HVAC system to heat the house. If that is the case then I am going to have to ration the heating each day and only use it for an hour max. Then it would be $180 more for the two months, which is doable for me but an hour of heating is not much help! I will go to the heating corp and ask them how much they think it costs to see if I am right. I should look at the make and model number of my A/C unit outside to see if I can get some info that way. Maybe I can look online and see how much power my HVAC system’s heating uses per hour and calculate it that way. I will probably just buy an efficient space heater instead.
