Common Questions
About This Calculator
How accurate is the Revenue Leak Calculator?
The calculator uses conservative industry benchmarks from HVAC and home services research, validated against our client engagements. The outputs are intentionally conservative — your actual losses are often higher. Think of the number as a floor, not a ceiling.
How much does the average HVAC business lose to missed calls?
HVAC businesses miss 27% of inbound calls on average. With an average job value of $350–$500 and a 45% conversion rate, that typically represents $4,000–$9,000 in lost monthly revenue from missed calls alone.
What is a revenue leak?
A revenue leak is any operational gap that causes your business to lose money it should have earned. Common leaks include missed calls, slow lead response, appointment no-shows, admin time that should be automated, unpaid invoices, low review scores, and unsold estimates sitting without follow-up.
How much does lead response time matter?
Businesses that respond within 1 hour are 7x more likely to convert a lead than those responding 2 hours later. After 24 hours, conversion probability drops by 78%. Speed of response is the single biggest lever in lead conversion for service businesses.
How many Google reviews does a service business need?
For local service businesses, 50+ Google reviews with a 4.5+ rating puts you in the top 20% of local competitors. Each new review drives roughly 5% more organic clicks on Google Maps. Businesses with under 4.0 stars lose an estimated 15–25% of potential leads to competitors.
What's the ROI on fixing revenue leaks?
Our clients typically recover their full setup investment within 30 days. A missed call recovery system costing $1,800 to set up typically recovers $3,000–$6,000 in the first month. The ongoing monthly ROI is substantial.
Is this calculator free to use?
Yes, completely free. No signup required to use the calculator. You can optionally enter your email to receive a copy of your results.

Most revenue leaks are fixable with the right AI and automation systems. Missed calls are solved with AI voice agents and instant text-back.
