What do Central Air Conditioners do?

A central air conditioning conditioner cools air in one spot before dispersing it throughout the residence using the furnace’s air handling capabilities. This sets it apart from window or wall a/c or mini-split systems, which all chill reasonably tiny locations and need many units to cool the whole home.

Most single-family homes in the United States with central air utilize a split system. This implies that the device is divided into 2 parts: an evaporator coil within house and a compressor outside.

Sizing for your Central Air Conditioner

Your professional will assist you in figuring out the proper size central air conditioner for your home. A system that is too little will run practically constantly, whereas a unit that is too big will chill the home too quickly and shut down prior to finishing a complete cycle.

The quick on/off in the latter situation is taxing on the system. It can trigger the evaporator coil to freeze, and a frozen coil avoids air from flowing. As a result, a huge a/c might be less effective at cooling than a smaller system.

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

We understand that numerous property owners like to have a general idea of what size they need ahead of time. central air conditioner size: To get the Btu required, increase the square video footage of your house’s conditioned location by 25, then divide by 12,000 to obtain the tonnage.

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

The only exception would be if you’re installing a/c in a new house, because the home builder will most likely handle it.

When working with a builder or independent HVAC specialist, don’t be hesitant to seek clarifying details or request expense breakdowns. Even if the contractor is not able to detail everything, they must be ready to communicate adequately to help you feel more at ease with the procedure.

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?

Rates differ based upon the local market and the job information, just like any significant job. For labor and materials, a normal split system central air conditioning installation using an existing furnace might cost in between $3,000 and $7,000 or more. Typically, 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 full retail rather than receiving a business discount, so the whole cost of the task may not be more affordable than the contractor’s price quote. You’ll likewise have to perform your own sizing, and you’ll be held accountable if there are any problems with the devices.

If you’re replacing an existing central air conditioning system, expect an extra rate to remove and get rid of of the old system and refrigerant. When constructing a heating system and cooling system, the expense of each component is often decreased, while the total 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.
