Typical BAS Installation Cost
A typical BAS installation is priced at $2.50 to $7.50 per square foot or roughly $400 to $1,500 per control point, depending on device type.
If you're budgeting for a smart building upgrade in Phoenix, Phoenix Commercial HVAC designs and installs building automation and HVAC controls for offices, restaurants, medical suites, and multi-tenant properties across the Salt River Valley. The figures below show how square footage, control points, device type, and project scale can move the installed cost.
A typical BAS installation is priced at $2.50 to $7.50 per square foot or roughly $400 to $1,500 per control point, depending on device type.
Building size separates small, mid-sized, and large-facility budgets, while device type changes the control-point figure.
Separate a whole-building BAS installation from a single fan coil unit or air handler retrofit before comparing estimates.

Control points across a commercial building so readers can see why device type influences point-level pricing.

Contrast a commercial building under 20,000 square feet with a mid-sized property to illustrate how the budget categories shift with scale.

Focus on one fan coil unit or air handler to distinguish a single-point retrofit from a whole-building installation.
Typical BAS installation cost runs $2.50 to $7.50 per square foot.
The point-level benchmark is roughly $400 to $1,500 per control point depending on device type.
Small buildings under 20,000 square feet often cost $50,000 to $300,000 fully installed; mid-sized properties run $200,000 to $700,000; large facilities and campuses can exceed $500,000 and reach $1,000,000+.
Retrofitting one fan coil unit or air handler typically costs $800 to $2,000 installed.
| Budget Basis | Typical Cost | Scope Note |
|---|---|---|
| Per square foot | $2.50 to $7.50 per square foot | Typical BAS installation range |
| Per control point | Roughly $400 to $1,500 per point | Device type changes the range |
| Small building | $50,000 to $300,000 fully installed | Commercial property under 20,000 square feet |
| Mid-sized property | $200,000 to $700,000 | Whole-building commercial installation |
| Large facility or campus | Can exceed $500,000 and reach $1,000,000+ | Large-scale BAS installation |
| Single-point retrofit | $800 to $2,000 installed | One fan coil unit or air handler |
BAS pricing can be framed by square footage, by control point, or by building-size category. A Phoenix estimate should match the actual property and device mix, because a whole-building installation is a different scope from one fan coil unit or air handler retrofit.
When comparing scope, identify the building size, device type, and whether the work covers one control point or a fully installed whole-building system. Also state whether the property is an office, restaurant, medical suite, or multi-tenant building so the estimate reflects the actual setting.
Should you budget by square footage or by control point? Either can frame a BAS installation, but device type changes the per-point figure. Is a single-point retrofit priced like a whole-building project? No: one fan coil unit or air handler is a narrower installed scope than a building-wide system.
Share the property type, building size, and controls you want to install or retrofit. The local team can use those project details and field data to define the BAS scope before preparing an estimate.
