Build an HVAC replacement-cost scenario from entered equipment, ductwork, electrical or controls, labor, access, and permit or inspection amounts. The model does not select or size equipment and does not supply a current local price.
Reviewed 2026-08-24
The educational planning result is derived from entered equipment unit count, equipment cost per unit, ductwork material allowance, electrical and controls allowance, labor hours, labor rate, permit and inspection allowance, installation access, and project ZIP. The optional neutral request-mode CTA, Submit HVAC Replacement Project Request, is enabled but remains separate from the math and does not promise a provider, rate, availability, or approval.
The calculator adds the entered equipment component, ductwork material component, electrical and controls material component, access-adjusted replacement labor component, and permit, inspection, and commissioning component.
Example HVAC replacement scenario
Equipment = 1 x $9,500 = $9,500. Ductwork = $2,400. Electrical and controls = $1,100. Labor = 14 x $125 x 1.20 x 1.00 = $2,100. Permit and inspection = $300. Total = $15,400; the displayed range is 90% to 110% of that total.
The modeled planning total is $15,400, with a $13,860 to $16,940 planning range for those inputs and assumptions.
Build an air-duct cleaning planning scenario from system and register scope, entered service amounts, labor, access, and an inspection or remediation allowance. This critically contained tool does not recommend routine cleaning or make a health, air-quality, diagnosis, or remediation claim.
Model an HVAC maintenance visit from entered inspection, consumable, replacement-part, testing, refrigerant-handling, service, disposal, and professional labor amounts. The calculator does not diagnose equipment, prescribe a maintenance cadence, or infer savings.

CostSignals results are planning estimates based on the values you enter and the calculator’s configured assumptions. Verify current rates, rules, project scope, and quotes independently before making decisions.
Fill in the form to get your estimate
Enter the number of equipment units represented by the per-unit amount. This is not a sizing recommendation.
Enter a current project-specific equipment amount. The calculator does not supply product pricing, capacity, efficiency, or eligibility.
Enter the project-specific duct material or modification allowance. System design and duct sizing are outside this arithmetic model.
Enter the project-specific material allowance for electrical work, controls, disconnects, pads, or similar scope. Do not include labor here.
Enter estimated project labor hours from the defined removal, installation, startup, and testing scope.
Enter the project-specific labor rate. The calculator does not supply or imply a current local rate.
Enter only a verified project amount. This field does not determine permitting, inspection, code, rebate, or commissioning requirements.
Apply an explicit labor-only access factor. The selected factor does not resize equipment or change entered material amounts.
Used only for available CostSignals location factors; it does not supply equipment selection, a price, a labor rate, or a code determination.
