HVAC Installation Revenue Calculator
Project installation revenue from leads, close rate, average system value and crew capacity.
Result
Service lines rarely carry the same margin. Splitting them is the only way to see which part of the business is paying for the rest, which is frequently not the part that looks busiest.

- Close rate on proposals, which is the main lever.
- Average system value, which moves with option presentation.
- Crew capacity, since installs consume days rather than hours.
Where this one goes wrong
Modelling installation revenue without crew days. Installations are capacity-bound in a way service is not, and a revenue target that exceeds available crew days is a plan to disappoint customers.
Questions
About this calculator
What raises average system value?
Presenting genuine options rather than one price. Customers given a clear choice between systems frequently select above the entry option; customers given one number decide only whether to buy.
How do I model crew capacity?
In install days per crew per month, allowing for weather, callbacks and commissioning returns. Nominal capacity and real capacity differ substantially.
Does replacement demand follow a pattern?
It concentrates with equipment failure, which concentrates with weather extremes. That means installation demand peaks exactly when service demand does, and they compete for the same people.
The formula
revenue = jobs x average value; gross profit = revenue x margin

A worked example
These are the figures the calculator opens with. Every number in the results column below is produced by the same calculation the page runs, so you can follow it through before putting your own figures in.
What goes in
| Input | Value |
|---|---|
| Installation jobs per month | 9 |
| Average value | $8,400 |
| Gross margin on this work | 38% |
| Share of total revenue | 40% |
What comes out
| Result | Value |
|---|---|
| Installation revenue per month main result | $75,600 |
| Per year | $907,200 |
| Gross profit per year | $344,736 |
| Implied total business revenue | $2,268,000 |
The installation line brings in $907,200 a year and earns $344,736 of gross profit on it.
How sensitive the answer is
Holding everything else steady and changing only average value, this is what happens to installation revenue per month. It is worth knowing which of your inputs the answer actually hinges on, and which barely move it.
| Average value ($) | Installation revenue per month |
|---|---|
| $4,200 | $37,800 |
| $6,300 | $56,700 |
| $8,400 example above | $75,600 |
| $12,600 | $113,400 |
| $16,800 | $151,200 |
Every other input is held at the example value while this one changes, which is not how a real job behaves. Treat it as a guide to which number matters most, not as five separate quotes.

Before you rely on this number
Sizing, capacity and load figures here are planning estimates. A real installation depends on the manufacturer's data for the specific equipment, the duct system it is going into, and a proper load calculation for the building. Use this to sanity-check a number or price a job, not to select equipment.
Estimating is the easy part
The jobs you never hear about cost more than the ones you mis-measure. BDEVY builds the marketing, systems and automation that bring them in.
