I have a 14x14 room that I need lone slightly cooled. We have a ceiling fan so that will serve with this. This unit is an joie de vivre star unit that says (based on 8c per killowatthour rates) that annually it should cost around $34.00. I understand that that was subsidise in 1995 that it was that low. I regard that it should be about double, but the landlord (who is roommate as well) say that if we use this, we will pay ALL extra to the electricity bill. About how much more per month can I expect to be paying?
Answers:    Before you buy it you might wanna think if is obedient enough for your room. Thats only appropriate for a closet. Under extreme weather conditions, you wanna get at least 15,000 btu a/c element . That should cost you about 400 dollars. The more SEER the more efficient. moral luck. You'll be paying about 15 dollars more per month. It isn't that much. Keep in mind that once you be in motion over the limit of power usage, the power consumption prize doubles too. There is a limit that edison allowes you to use, you turn over your limit they double charge you.
like adjectives other landlords charge is $30 per month, per a/c.
if they want to charge you more, MOVE!
