What do Central Air Conditioners do?

A main air conditioner cools air in one area before distributing it throughout the residence using the heater’s air handling capabilities. This sets it apart from window or wall air conditioning system or mini-split systems, which all chill fairly small locations and require many units to cool the entire home.

Sizing for your Central Air Conditioner

The fast on/off in the latter circumstance is taxing on the system. It can trigger the evaporator coil to freeze, and a frozen coil prevents air from flowing. As a outcome, a big ac system may be less reliable at cooling than a smaller system.

Your Air Conditioner installation will do a computation referred to as a “Manual-J” to determine the very best unit for your house. This will take into account all of the specifications we’ve discussed and more, resulting in the most precise size possible.

Nevertheless, we comprehend that lots of house owners like to have a basic concept of what size they need ahead of time. Here’s a rough estimation of central air conditioner size: To get the Btu needed, increase the square footage of your house’s conditioned area by 25, then divide by 12,000 to acquire the tonnage.

Keep in mind that this is simply a standard estimate, and there are numerous aspects. If your home’s very first flooring has 12-foot ceilings, the air conditioner will have more air to chill.

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?

Prices differ based upon the local market and the task information, just like any significant project. For labor and products, a typical split system central air installation utilizing an existing heating system might cost in between $3,000 and $7,000 or more. On average, that expense will be divided around 60/40, with labor accounting for most of it.

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

If you’re changing an existing central air conditioning system, expect an additional cost to dispose and eliminate of the old system and refrigerant. When developing a heating system and a/c system, the cost of each element is frequently lowered, while the general cost of the work is higher.

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.
