Commercial HVAC maintenance costs: build a defensible annual budget
Build an annual commercial HVAC maintenance budget from equipment, service scope and exclusions instead of relying on a national average.
Annual maintenance budget
Turn your own per-unit annual quotes into a low and high planning allowance. Defaults are illustrative, not market rates.
Build a scope before a budget
Enter the number of comparable units and two annual per-unit figures from quotes with the same task list. The calculation is unit count × annual per-unit cost + annual shared costs. Shared costs might include an access allowance or a reporting charge; enter them only if they are not already included in the unit price.
For the illustrative default, six units × $600 + $500 = $4,100 at the low end. Six × $900 + $500 = $5,900 at the high end. These invented inputs demonstrate the arithmetic. They are not researched market rates. The scenarios are examples of input structure, not recommendations or promises of coverage.
Do not mix a per-visit quote with an annual quote. Convert visits to a yearly total first. Run separate calculations for dissimilar equipment and add the results outside this tool. Taxes, repairs, refrigerant, emergency work and replacements are excluded unless you put them into a quoted input. A range is not a probability interval. Keep both quotes and their exclusions with your budget.
