New central air for an existing or renovated home
Adding central air starts with a route through the house. We plan the indoor coil, outdoor unit and supply-and-return paths so the installation fits the rooms it will serve.
Ducts are already there
A forced-air heating system can provide part of the route for central cooling. Its blower, duct capacity and available coil space still need to suit the proposed AC.
We also look at return-air paths and rooms that have changed since the ducts were installed. Existing distribution is a starting point, not an automatic approval for new cooling.
New routes are needed
Basements, attics and closets may offer routes for new ducts. The design needs to account for access, insulation, room outlets and the effect on finished spaces.
If practical routes are limited, compare a mini split arrangement before committing to central distribution.
See ductless and ducted mini splitsA central AC installation includes more than the equipment visible from the yard. These connections belong in the design discussion.
The indoor coil works with the outdoor AC. A compatible blower moves air across it.
Supply ducts and outlets carry conditioned air into the spaces included in the design.
Air needs a route back to the system, including when bedroom doors are closed.
The outdoor unit needs airflow, clear access and a workable connection to the indoor coil.
The condensate drain is a separate route. Cooling removes moisture from the air, and that water needs an appropriate path away from the indoor equipment.
A shaded first floor and an upstairs room with afternoon sun do not behave the same way. Window area, insulation, air leakage and the rooms included in the project all influence the cooling load.
Ask how the proposed capacity was determined. A room-by-room load assessment, commonly called Manual J, gives the equipment discussion a firmer basis than copying a neighbor’s AC size.
The installation also has to deliver the intended airflow. A restrictive return path can limit performance even with new equipment.
| Location or connection | What the installation needs to cover |
|---|---|
| Outdoor position | A stable mounting location, manufacturer clearances, service access and a practical line route. Include any property or association restrictions in the discussion. |
| Indoor coil and blower | Compatible equipment, space for the coil and transitions, and access for future filter changes. |
| Electrical supply and controls | The requirements of the selected equipment, thermostat compatibility and any associated changes in the agreed scope. |
| Ducts and condensate | New or modified duct connections, insulation where needed, drainage and access to the finished installation. |
Identify the rooms served, equipment positions and the routes that will be opened or modified.
Confirm equipment, associated work, permit responsibilities and any exclusions such as finish repairs.
Clear the agreed work areas. The equipment and connections are installed as part of the planned system.
Review cooling operation, the thermostat, filter access and the documents supplied with the installation.

About City VentilationsThe equipment, available ductwork and the work needed to connect the system affect the price. New duct routes, limited access and changes to indoor or outdoor locations can add scope. Compare itemized proposals for the same installation.
Some homes have accessible routes; others need work through finished areas. Ask which surfaces will be affected and who handles closing, patching and painting before you approve the project.
That depends on its blower, controls, condition and the space for a compatible cooling coil. We review the actual indoor equipment as part of planning the AC.
If the project mainly replaces equipment in an existing central system, start with our AC replacement service. A major layout change can still require installation planning.
