How much does it cost to run an air conditioner?
A 2.5 kW air condinter will cost about 22 cents an hour to run. Alternatively, a 9 kW air conditioner will cost $6.30 to run for 8 hours at full power. The table below shows you common sizes and cost associated with them.
Why does an air conditioner need to sit for 24 hours?
The outside unit was delivered with a quantity of refrigerant and lubricant already installed. In cooler weather, it will be a liquid. Normally, it will be pooled in the crankcase at the bottom of the compressor. However, if enough finds its way into the compressor cylinder, you may get hydro-lock on that liquid when you first start the compressor.
How many watts does an air conditioner use per hour?
This means our A/C unit will produce 5000 BTUs of cooling in an hour of running. Since SEER=10 means that 10 BTUs used per Wh, then 5000 BTUh / 10 SEER = 500 Watts per hour that our A/C unit will use.
Why is running your aircon 24 / 7 is a bad idea?
Running aircons 24/7 clogs its air filters with dirt. This would cause the unit to blow out warm air instead of cool. However, this is the least of the potential problems since air filters are cheap and easy to replace. The condenser coils continually accumulate hardened dirt from the filters that starts clogging.
How much does it cost to run an AC unit for an hour?
This is $0.54216. This is the cost to run an air conditioner for an hour. The formula is kWh x kWh unit cost = cost to operate an AC for an hour. To determine how much it will cost you to run your air conditioner all summer, total the number of hours the unit will run over the season and multiply by the kWh cost.
