What missed calls cost HVAC, plumbing and roofing companies
Missed calls per week × 4.33 × the share who would have booked × your average job value equals revenue at risk each month. With typical 2026 values (about $350 for an HVAC repair, $300 to $500 for a residential plumbing call, about $1,150 for a roof repair), even a few missed calls a week can cost thousands a month.
The math in one line
Missed calls per week × 4.33 × share who would have booked × average job value = revenue at risk each month.
Example: 10 missed calls a week, a third of which would have booked, at $350 a job, is about $5,000 a month at risk. Try your own numbers in the calculator on our HVAC page.
Typical job values in 2026
| Trade | Typical value | Source |

Why home service calls get missed
- Technicians are on a job with their hands full.
- The office closes at 5, but furnaces, pipes and roofs fail at night.
- Storms and heat waves create call spikes no single line can handle.
- Calls go to voicemail, and most people don't leave one; they call the next company.
How to stop the leak
- Answer every call: an AI receptionist answers in one ring, triages emergencies by your rules and books the job.
- Text back instantly: anyone who hangs up gets a text within seconds.
- Follow up quotes: automated reminders until the customer decides.
- Get found: a strong Google Business Profile and reviews bring more of the right calls. See Local SEO.

A worked example for each trade
These examples use the job values cited above with illustrative call volumes. Replace them with your own.
| Trade | Missed calls a week | Would have booked | Job value used | Monthly revenue at risk |
|---|---|---|---|---|
| HVAC repair | 10 | 1 in 3 | About $350 | About $5,000 |
| Plumbing | 8 | 1 in 3 | Your average ticket | Calls x rate x ticket x 4.3 |
| Roof repair | 5 | 1 in 4 | Your average repair | Calls x rate x ticket x 4.3 |
The formula is always the same: missed calls per week, times the share who would have booked, times your average job, times 4.3 weeks.
Three levels of fix
| Level | What it does | Good for |
|---|---|---|
| Missed-call text back | Texts the caller in seconds | Lowest cost, quick to launch |
| AI receptionist | Answers, books and transfers emergencies | Businesses with steady call volume |
| Both, plus follow-up | Catches calls, texts and web leads in one pipeline | Companies running ads or with several crews |
