The Central Air Installation Process

It should take around a day to complete the installation. The major steps are summarized here.

  • Duct work installation or modification
    • Any duct work should be limited in homes with existing furnaces or air conditioning, generally no more than an extra return line.
    • If ducts must be placed, work with your contractor to disguise them in closets or soffits to minimize expensive drywall repairs.
    • Duct work should be done before drywall is put in new construction.
  • Interior unit
    • The evaporator coil is installed within the furnace plenum.
      • The plenum is the part of the furnace on each side of the air handler where air enters and exits the home.
      • The evaporator coil will enter the supply plenum, which serves as the furnace’s “outflow.”
  • Exterior unit
    • Several considerations influence the positioning of the outside unit, including:
      • The distance between the inside unit and the electrical service panel;
      • The levelness of the ground;
      • The proximity of the loud external unit to windows or doors;
      • Distances needed by code from gas or water meters (refer to your local building department for specifics).
  • Connect the line set
    • A pair of copper pipes connects the two parts of a split system, forming the direction the refrigerant will take.
    • The most direct route from the evaporator to the condenser will primarily decide the course of the line set.
      • If you have any issues regarding the route, communicate them to the contractor as soon as possible.
      • To avoid water infiltration, the penetration to the external should be sealed.
  • Connect the Electrical Supply
    • An outside cutoff will be required for the condenser unit.
    • The electrical line will connect the condenser to the shutdown, then to the electrical service panel.
    • If your circuit panel is already overloaded, you may need to update it to withstand the extra demand of the air conditioner.
      • If the project was planned properly, any work on the panel should already be included in the project estimate.
    • There will also be a low-voltage wire connecting the condensing unit to the furnace so it can be controlled by the thermostat.
  • Condensate Drain Line
    • All air conditioners generate condensation, much like the sides of a glass of ice water. That condensation needs to be drained.
    • Units located in a basement typically run to a floor drain.
    • Units located in attics may pipe water outside, or may use a drain pan that allows water to evaporate — the same way refrigerators allow condensation to evaporate.
  • Thermostat
    • When installing central air conditioning in a new home, you must select a thermostat.
    • If you’re retrofitting central air conditioning into an older home, you may need to replace the thermostat with one that can also manage cooling.
    • This is one phase in the process that is ideal for a little do-it-yourself effort.
      • Some homeowners buy a basic thermostat for the installation and subsequently upgrade to a programmable or smart thermostat on their own.
