For the great bulk of homes, central air installation is complicated and filled with danger to attempt without professional support.

What do Central Air Conditioners do?

A main air conditioner cools air in one area before dispersing it throughout the house using the heating system’s air handling capabilities. This sets it apart from window or wall air conditioning unit or mini-split systems, which all chill fairly small locations and need lots of units to cool the entire house.

The majority of single-family homes in the United States with main air use a split system. This indicates that the gadget is divided into 2 parts: an evaporator coil within your home and a compressor outside.

Discuss with your specialist just how much you worth energy efficiency above initial expense. This is also an exceptional minute to talk about the position of the condenser unit and the kind of thermostat you pick.

Sizing for your Central Air Conditioner

Your contractor will assist you in identifying the appropriate size central air conditioner for your home. A system that is too little will run practically continuously, whereas a system that is too large will chill the home too quickly and shut off prior to completing a complete cycle.

The fast on/off in the latter scenario 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 ac system may be less effective at cooling than a smaller unit.

Your Air Conditioner installation will do a computation known as a “Manual-J” to identify finest unit for your home. This will take into consideration all of the parameters we’ve pointed out and more, leading to the most exact size possible.

We comprehend that numerous property owners like to have a basic concept of what size they need ahead of time. Here’s a rough evaluation of central air conditioner size: To get the Btu needed, multiply the square video of your house’s conditioned area by 25, then divide by 12,000 to get the tonnage.

If you have numerous of those windows, you may require more cooling.

Getting an Estimate for a Central Air Conditioner in Salem, MA 01970

contractor needs to use you an price quote as soon as you’ve discussed the basic plan and talked about design possibilities. As constantly, obtain composed estimates from various providers. The only exception would be if you’re setting up cooling in a brand-new home, because the builder will most likely handle it.

When working with a builder or independent HVAC specialist, do not be hesitant to seek clarifying information or demand expense breakdowns. Even if the specialist is not able to detail everything, they need to be prepared 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 vary based upon the regional market and the job information, similar to any considerable job. For labor and materials, a common split system main air installation using an existing heater might cost between $3,000 and $7,000 or more. Usually, that expense will be split around 60/40, with labor accounting for majority of it.

Bear in mind that you will most likely be paying complete retail rather than getting a industrial discount, so the entire expense of the task may not be cheaper than the contractor’s estimate. You’ll also have to perform your own sizing, and you’ll be held responsible if there are any issues with the equipment.

remove and get rid of of the old system and refrigerant if you’re changing an existing central air system. When building a heating system and a/c system, the expense of each part is often lowered, while the overall 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.
