The Economics of Missed Calls in HVAC: 15 Seconds That Change Your Month

Let’s be blunt: most HVAC shops don’t have a leads problem—they have a response problem. When a homeowner’s AC dies, they’re not “considering options.” They’re calling down Google until someone picks up. The business outcome is decided in the first 15 seconds.

Do the math with round numbers:

30 inbound calls/week

Answer rate today: 60% → 18 answered

With ring-then-receptionist: 85% → 25.5 answered

Set rate: 55% (appointments from answered calls)

Close rate: 65% (jobs from set appointments)

Avg ticket: $650

Now multiply it through:

• Baseline: 30 × 0.60 × 0.55 × 0.65 × $650 = ~$4.2k/week

• With clean failover: 30 × 0.85 × 0.55 × 0.65 × $650 = ~$5.9k/week

That’s ~$1.7k/week (call it ~$7.5k/month) in upside before touching pricing or ads.

If you’re wondering whether phones still convert in 2025, the answer is yes—loudly. Invoca’s 2025 benchmark (60M+ calls) pegs phone-lead conversion at ~37% across industries when handled well. That lines up with what we see on the ground: calls are still the highest-intent channel in home services when someone actually picks up.

And if you like third-party takes on speed-to-lead, Scorpion’s June 10 post rounds up why sub-five-minute responses win disproportionately in home services.

So what actually changes the numbers? Make voicemail the backup singer, not the headliner. Ring the team first, then pass unanswered calls to the receptionist that can gather details and drop a short summary where your dispatcher lives. Tie every attempt to a log so staffing and training come from data, not vibes. The end state isn’t fancy; it’s just reliable—and reliability turns “we’ll try you back” into “we’ll be there today.”

Where we fit: we give you that 15-second safety net. If your team can’t pick up, the AI does—captures the job, confirms the number, and pushes a clean summary into your FSM. No drama, just fewer missed jobs.
