Adding central air conditioning into an existing forced-air heating system means you may be rid of noisy, dripping window AC units forever. And since the ductwork to distribute the cooled air throughout the house exists, the whole project can be completed by heating/cooling technicians in two or three days. In most cases they won’t have to make important changes to the ductwork.
The cost will vary according to the home dimension, orientation to the sun, amount of insulation and positioning of windows and doors. These factors affect the size and efficacy level of their cooling equipment you’ll need. As of publication time, expect to pay from $3,000 to $3,500 in the very low end and from $4,000 to $6,000 in the high end to include central air conditioning into the forced air heating system in a 2,000-square-foot house that’s existing ductwork. As there are lots of cost variables, plan on obtaining at least three bids.
