How much does it cost to run my A/C

How much does it cost to run my Air conditioner?

FAQ

A question we get asked often is: “How much does it cost to run my Air conditioner”?

We have to ask a few questions first, What size is you’re A/C? How efficient is you’re A/C? How much is our local utility charging per KW hour?

 

 Now we can do the math:

For an average 3 ton (36K BTU size) 10 SEER (efficiency rating) we would expect total power draw to be 2.94 KW per hour, with summer cooling hours of 1,100*, and a cost of $0.06 per KW.

2.94 x .06 x 1100 = $194.00 per year for an average (will increase if thermostat is set lower) or $0.1764 cents per hour.

For an average 3 ton (36K BTU size) 17 SEER (efficiency rating) we would expect total power draw to be 1.89 KW per hour, with summer cooling hours of 1,100*, and a cost of $0.06 per KW.

1.89  x .06 x 1100 = $124.00 per year for an average (will increase if thermostat is set lower) or $0.1134 cents per hour.

The SEER is the relation of BTU output per KW of power used.  Jumping from a 8 SEER to a 16 SEER will cut the energy use in half.  The minimum SEER now available is 13, and a maximum for standard Units around 21.  Some GEO thermal loops and inverter compressors can achieve up to 26 or higher SEER.
