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.

How Much Does Central Air Installation Cost?

Costs differ based on the regional market and the job details, similar to any substantial job. For labor and materials, a common split system central air conditioning installation utilizing an existing heater could cost between $3,000 and $7,000 or more. On average, that expense will be split around 60/40, with labor accounting for most of it.

Bear in mind that you will most likely be paying full retail rather than getting a industrial discount rate, so the entire expense of the job might not be cheaper than the specialist’s price quote. You’ll also have to perform your own sizing, and you’ll be held responsible if there are any issues with the devices.

If you’re changing an existing main air conditioning system, expect an extra price to dispose and get rid of of the old system and refrigerant. When constructing a heating system and air conditioning system, the cost of each part is regularly decreased, while the overall expense of the work is greater.

Repair/Retrofit vs New Unit Installation

If boiler replacement is likely within the next few years or if you intend on transitioning to a new home heating system, you might want to give some thought to skipping the boiler retrofit and go right to setting up a brand new energy-efficient, eco-friendly heating system.
