In the summer, when the heat really gets to be intolerable, many of us are tempted to rip out that noisy, drippy window air-conditioning unit and replace it with a quiet, energy-efficient, central-air conditioning system. However, we don’t because we are worried about the cost, and those of us with forced-air furnaces with existing ducts may be concerned that altering the system will affect the furnace’s efficiency, as well. Those of us without duct work don’t even want to think about destroying our homes to get the work done, or the cost. But, the cost of hiring an Air Conditioning Installation in Charlotte, NC professional is easier and cheaper than you may think. The average cost of adding central air to an already existent forced-air heating system for a home that is about 2,000 square feet will run between $3,500 and $4,000. The work can be completed in just a couple of days and many times there is little or no change to the current ducting. For homes that need ductwork, double that time and cost. If you hire an Air Conditioning Installation in Charlotte, NC contractor who is good at retrofitting, he can conceal the ducting behind walls, in the backs of closets or up in the attic with little cutting and mess.
