Central Air Conditioner Installation in Washington, DC 20008

For the great bulk of homes, central air conditioning installation is complex and stuffed with threat to try without professional assistance. This is owing to the competence needed, the administrative wrangling of authorizations and licensing requirements, and the threat of voiding guarantees if the parts are set up mistakenly.

What do Central Air Conditioners do?

A central air conditioner cools air in one spot before dispersing it throughout the house utilizing the furnace’s air handling abilities. This sets it apart from window or wall air conditioning system or mini-split systems, which all chill fairly small areas and need many systems to cool the entire house.

A lot of single-family houses in the United States with central air conditioning use a split system. This indicates that the device is divided into two parts: an evaporator coil within home and a compressor exterior.

Working With Professional Central Air Conditioner Installers in Washington, DC

When speaking with professionals, ask about their approach to the job. Pay attention to the concerns they ask! An installer should ask clarifying questions so that your preferences and decisions are represented in their estimate and the end outcome.

Planning for Central Air Installation in in Washington

Setting up central air conditioning is a large endeavor that needs significant preparation ahead of time. Request that your contractor check their procedure and verify that they will manage any required permits or other important documents.

Go over with your professional how much you worth energy effectiveness above preliminary expense. This is also an excellent moment to talk about the position of the condenser system and the kind of thermostat you pick.

Sizing for your Central Air Conditioner

Your specialist will assist you in figuring out the suitable size central air conditioner for your home. A system that is too little will run virtually continuously, whereas a system that is too big will chill the home too quickly and shut down before completing a full cycle.

The quick on/off in the latter circumstance is taxing on the system. It can cause the evaporator coil to freeze, and a frozen coil prevents air from streaming. As a outcome, a huge air conditioning unit 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 identify the very best system for your home. This will consider all of the parameters we’ve mentioned and more, leading to the most precise size possible.

We comprehend that many homeowners like to have a basic idea of what size they require ahead of time. Here’s a rough evaluation of main air conditioner size: To get the Btu needed, 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 merely a standard price quote, and there are several 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?

Costs vary based on the regional market and the task information, similar to any significant job. For labor and materials, a normal split system central air installation using an existing heater might cost between $3,000 and $7,000 or more. Usually, that expense will be divided around 60/40, with labor accounting for bulk of it.

Bear in mind that you will most likely be paying complete retail rather than getting a industrial discount rate, so the whole cost of the project may not be cheaper than the professional’s price quote. You’ll also have to perform your own sizing, and you’ll be held liable if there are any issues with the devices.

If you’re replacing an existing central air conditioning system, expect an additional cost to eliminate and dispose of the old system and refrigerant. When constructing a furnace and cooling system, the cost of each component is regularly decreased, while the general expense 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.
