A central air conditioning conditioner cools air in one spot before dispersing it throughout the residence 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 tiny areas and need lots of systems to cool the entire house.

Sizing for your Central Air Conditioner
Your professional will help you in identifying the appropriate size central air conditioner for your house. A unit that is too little will run practically continually, whereas a unit that is too large will chill the house too rapidly and turn off before finishing a full 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 prevents air from streaming. As a result, a huge ac system might be less effective at cooling than a smaller sized system.
Your Air Conditioner installation will do a calculation called a “Manual-J” to recognize best system for your house. This will take into consideration all of the parameters we’ve discussed and more, resulting in the most accurate size possible.
Nevertheless, we comprehend that numerous house owners like to have a basic notion of what size they require ahead of time. Here’s a rough estimate of main air conditioner size: To get the Btu necessary, increase the square video footage of your home’s conditioned location by 25, then divide by 12,000 to acquire the tonnage.
Keep in mind that this is simply a standard price quote, and there are numerous factors. If your home’s first flooring has 12-foot ceilings, the air conditioner will have more air to chill.
Getting an Estimate for a Central Air Conditioner in San Bruno, CA

The only exception would be if you’re installing cooling in a brand-new house, given that the contractor will probably manage it.
When working with a home builder or independent HVAC professional, do not be reluctant to seek clarifying details or demand cost breakdowns. Even if the contractor is not able to information everything, they should be prepared to interact sufficiently to help you feel more at ease with the procedure.
How Much Does Central Air Installation Cost?
Rates differ based upon the local market and the job information, as with any significant task. For labor and materials, a normal split system central air installation using an existing furnace might cost in between $3,000 and $7,000 or more. Usually, that cost will be split around 60/40, with labor accounting for bulk of it.
Bear in mind that you will most likely be paying full retail rather than getting a industrial discount rate, so the entire expense of the project may not be less expensive 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 devices.
If you’re changing an existing main air conditioning system, expect an additional cost to get rid of and remove of the old system and refrigerant. When constructing a furnace and a/c system, the expense of each element is often reduced, while the overall cost of the work is higher.
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.
Repair/Retrofit vs New Unit Installation
If air conditioning 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 AC retrofit and go right to setting up a brand new energy-efficient, eco-friendly Central Air Conditioning system.
