HVAC Job Profit

See what one job leaves after labour, parts and the overhead it consumed, rather than what the invoice said..

HVAC Labour Rate

Your billable rate has to carry three things: what the tech costs you, what the business costs to run, and the profit you want left over.

HVAC Estimate Calculator

Build an estimate from equipment, labour, materials and the items a changeout usually needs but rarely gets quoted..

HVAC Markup vs Margin

Convert between markup and margin so a target set in one is not applied as the other..

HVAC Markup Calculator

Apply a markup to job cost and see the margin that markup actually produces..

HVAC Maintenance Cost

Cost a maintenance visit properly, including travel, the filter and the admin that surrounds it..

HVAC Invoice Calculator

Build an invoice total from parts, labour, tax and any discount, with the discount visible rather than buried..

HVAC Job Costing

Total what a job actually cost: burdened labour, equipment, materials, travel and the overhead it consumed..

HVAC Accounts Receivable

See how much cash is tied up in unpaid invoices and how far past terms it has drifted..

HVAC Field Service Efficiency

Measure how much of the working day turns into completed, invoiced work rather than movement and admin..

HVAC Callback Cost

Work out what a callback actually costs once the return visit, the lost capacity and the reputational effect are counted..

HVAC Tonnage

Convert between BTU and tons and sanity check a proposed capacity against the space..

HVAC Capacity

Compare the capacity a space needs against what is installed, and see the gap in both directions..

HVAC CFM

Check airflow against equipment requirement, and against what the duct system can realistically deliver..

HVAC Duct Size

Size a duct run from required airflow and the static pressure the system has available..

HVAC Filter Size

Check filter face velocity, which decides whether a filter chokes the system or loads at a sensible rate..

Refrigerant Charge

Estimate line set charge adjustment as a planning figure, alongside the manufacturer's charging procedure rather than instead of it..

Equipment Life

Estimate remaining service life from age, maintenance history and operating conditions, as context for a replacement conversation..

HVAC Repair Cost

Price a repair from diagnosis, parts and the labour the specific fault actually requires..

HVAC Installation Cost

Cost an installation across equipment, crew hours, materials and everything the changeout uncovers..

HVAC Labor Cost

Work out what an hour of technician time costs once burden, vehicle and unsold hours are all counted..

Technician Cost

Work out the full annual cost of a technician, including everything that arrives with them beyond the wage..

Service Call Pricing

Price a service call so the diagnostic time, the travel and the van are all recovered before any repair is sold..

HVAC Proposal

Build a proposal with options, so the customer chooses between systems rather than deciding whether to buy at all..

HVAC Pricing

Set a price from full job cost and the margin you intend to keep, rather than from a markup applied to parts..

Parts Markup

Price parts so sourcing, stocking and warranty are recovered rather than applying one percentage to everything..

Labor Markup

Check what your billed labour rate recovers against what an hour actually costs once burden and unsold time are counted..

HVAC Margin

Work out the gross margin a job returned once labour, equipment, materials and the travel are all counted..

HVAC Revenue

Project revenue from job volume, average ticket and the mix between service and installation..

Business Revenue

Model total business revenue across service, maintenance, repair and installation, with capacity as the constraint..

HVAC Repair Revenue

Project repair revenue from call volume, close rate on recommended work and average repair value..

HVAC Maintenance Revenue

Project maintenance revenue from plan members, visit frequency and the repair work those visits generate..

HVAC Installation Revenue

Project installation revenue from leads, close rate, average system value and crew capacity..

HVAC Replacement Revenue

Project replacement revenue from the equipment in your service book that is approaching end of life..

Agreement Revenue

Project recurring revenue from the agreement book, including renewal and the work the visits generate..

Maintenance Agreement

Model an agreement across its full year: visits owed, cost to deliver, revenue and what it produces in additional work..

Maintenance Plan Pricing

Set plan pricing from delivery cost and the margin you intend, with the discount you give members counted in..

Agreement ROI

Compare what an agreement book costs to run against the revenue and pull-through work it generates..

Revenue Per Truck

Work out what each truck returns and whether adding another is justified..
