There are two types of central air conditioning systems: A split system, which has a condenser unit outside and an evaporator unit inside, and a packaged system, in which the compressor and evaporator are in a single outdoor unit. Split units do not require duct work, while packaged units do.Adding central air conditioning to a home with an existing forced-air heating system in a 2,000-square-foot house averages $3,000 - $4,000. If ducts need to be added, the cost can double, and a split unit is the way to go.As opposed to window units, a ductless system is quieter, and can also heat your home.he higher the SEER rating, the higher the central air conditioner's cooling efficiency and the less electricity it will use, but the more expensive it will be to purchase. An additional factor to consider is the bel rating, or decibel level the unit produces. Units with a lower bel rating are typically priced higher.
Below is a breakdown of the cost to operate an in-room air-conditioning unit for a day and for a month. In general, the higher the BTU rating, the more electricity your unit will pull. And, of course, the energy draw will vary by make and model. 6,000 BTU Air Conditioner (approximately 560 watts) This unit could cool a room up to 260 sq. ft. 24 hours/day: $2.42 per day or $72.58 per month. The math: (560/1,000) x ($0.18 per kWh) x 24 hours per day x 30 days. 12 hours/day: $1.21 per day or $36.29 per month.
