Central Air Conditioner Installation in Portland, OR 97220

For the great majority of houses, central air conditioning installation is complex and fraught with danger to try without expert help. This is owing to the expertise necessary, the administrative wrangling of consents and licensing requirements, and the threat of voiding service warranties if the components are set up incorrectly.

What do Central Air Conditioners do?

A central air conditioning conditioner cools air in one area prior to distributing it throughout the home utilizing the heating system’s air handling capabilities. This sets it apart from window or wall a/c unit or mini-split systems, which all chill relatively small areas and require many units to cool the entire home.

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

Planning for Central Air Installation in in Portland

Installing main air conditioning is a big endeavor that needs significant preparation ahead of time. Demand that your professional check their procedure and validate that they will handle any needed authorizations or other important documentation.

Go over with your specialist how much you worth energy effectiveness above preliminary expenditure. This is also an outstanding minute to discuss the position of the condenser system and the kind of thermostat you choose.

Sizing for your Central Air Conditioner

Your professional will assist you in identifying the appropriate size main air conditioner for your house. A system that is too little will run virtually constantly, whereas a system that is too large will chill the house too rapidly and turn off prior to finishing a full cycle.

The quick 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 streaming. As a result, a big air conditioning system may be less reliable at cooling than a smaller unit.

Your Air Conditioner installation will do a computation referred to as a “Manual-J” to determine best unit for your house. This will consider all of the criteria we’ve mentioned and more, leading to the most precise size possible.

Nevertheless, we comprehend that many homeowners like to have a general notion of what size they need ahead of time. Here’s a rough estimation of central air conditioner size: To get the Btu necessary, increase the square footage of your home’s conditioned area by 25, then divide by 12,000 to get the tonnage.

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

Once you’ve gone over the basic plan and discussed design possibilities, the professional must provide you an price quote. As always, obtain written price quotes from various suppliers. The only exception would be if you’re installing cooling in a brand-new home, given that the home builder will most likely manage it.

When working with a contractor or independent HVAC specialist, do not be reluctant to seek clarifying information or demand cost breakdowns. Even if the professional is not able to detail whatever, they should be prepared to interact adequately to assist 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 on the regional market and the task details, as with any significant task. For labor and materials, a normal split system central air installation utilizing an existing heater could cost between $3,000 and $7,000 or more. Typically, that expense will be split around 60/40, with labor accounting for majority of it.

Nevertheless, bear in mind that you will more than likely be paying full retail instead of receiving a commercial discount, so the entire cost of the project might not be more affordable 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 problems with the equipment.

dispose and remove of the old system and refrigerant if you’re replacing an existing central air system. When building a heater and air conditioning system, the cost of each component is regularly reduced, while the general 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.
