How much does it cost to turn on the Air-Con for 1 hr? what's the hourly elec. rates? my bills are damn ex.!!!

Answer 1

If your AC system operates at 120VAC you can easily measure its electrical consumption. There is no way I can estimate how much electricity your system would use as there are too many variables. Purchase this meter and you will know exactly the electrical requirements.

The kWH rate should be on your electric bill. You likely have a flat monthly fee plus an added usage fee.

Well think of it this way, during the heat of the day, it is going to cost more becuase your AC has to work more to drop the temperature to what you desire. If it is always running, it will cost more over all but turning it on initially costs something just to give it the juice to start up, just like a car with gas. It takes more gas to start it then to let it run for a little while. (not recommended in areas where crime could cost you)

As previously said, the price can be up to double what you pay in the winter in the summer but I think that is based on what you have your thermostat set at. My brother has his at 68 degrees.

If your bills are through the roof, consider this option. At night a friend would use the cool air of the outside to cool his room by running a fan at night with the windows open and then close all the windows in the morning and make the place as dark as possible during the day to minimize heat. Sunlight heats up air.

Just an idea.

Answer 3

Depends on your unit and your electric rates But here is an example based on my unit, which is an 28000 - 35000 BTU unit. It is a York, energy star, whole house unit.

It uses 80 watts when the compressor is not running.

It uses 350 watts when the compressor is running.

On a very hot day here (say 90 to 95 degrees) the compressor runs about half to 2/3 of the time. I'll use 2/3 for the math.

So 80 watts X 8 hours = 640 watts
350 watts X 16 hours = 5600 watts
So per day consuption is 6240 watts or 6.24 kilowatts.

Our local rates are about 17 cents per kilowatt, with taxes about 20 cents per kilowatt.

So 6.24 kilowatts times 20 cents per kilowatt equals $1.25 per day to cool an 2150 square foot house.

Answer 4

Air Conditioner you have must not be very efficient. You summer electric rate should be about double your winter rate if AC is always on. So if you pay $55 a month in winter you will pay $110 in summer. works only as a general rule. If you turn AC on and off it uses lots lots lots more energy (electricity) to get the room cool. Always cheaper to budget for summer rate and just leave it on.
