ORIGINAL RESEARCH
We Called 25 HVAC Companies on a Tuesday Afternoon. Here’s What Happened.
By Charles Ashe
|We called 25 HVAC companies in Charleston, SC between 2 and 5 PM on a regular Tuesday. 60% went straight to voicemail. Only 3 out of 25 could answer live, provide availability, and book an appointment on the spot. The revenue impact of this gap is $3,000 to $7,000 per month for the average HVAC contractor.
How We Ran the Study
Study design and parameters.
Sample
25 HVAC companies in the Charleston, SC metro area selected from Google search results and Google Maps listings.
Timing
Called between 2:00 PM and 5:00 PM EDT on a Tuesday. Not a weekend, not a holiday, not after hours. A regular workday afternoon during normal dispatch hours.
Scenario
Posed as a homeowner with a 15-year-old system considering replacement. Ready to discuss pricing and availability.
Measured Outcomes
Four outcomes for each call: answered live, went to voicemail, put on hold 3+ minutes, or answered but could not provide availability or book.
What We Found
Results from 25 calls placed during normal business hours.

This was not an after-hours test. This was the middle of a workday afternoon, during what should be peak dispatch hours. The 3 companies that handled the call in real time set the standard. The other 22 lost the conversation before it started.
Why Do HVAC Companies Miss Calls During Business Hours?
The root cause is process, not staffing.
The missed call problem is rarely a staffing problem. It is a process problem. The call comes in. The dispatcher is on another line. The tech is in the field. The office manager is processing an invoice. Nobody is free, so the call rolls to voicemail. By the time someone calls back, the homeowner has already spoken to a competitor who answered.
The companies with the highest Google review counts were not necessarily the best responders. Reputation gets the phone to ring. Process determines whether anyone picks it up.
How Much Does This Cost an HVAC Company?
Revenue impact using conservative industry benchmarks.
THE MATH
Average HVAC service ticket: $350
Lead-to-close conversion rate: 25-30%
Missed calls per day (based on our data): 2-4
AT 2 MISSED CALLS PER DAY
60 missed calls/month × 28% conversion × $350
$5,880/month
$70,560 per year
AT 4 MISSED CALLS PER DAY
120 missed calls/month × 28% conversion × $350
$11,760/month
$141,120 per year
Annualized, that is $70,560 to $141,120 per year walking out the door. Not from bad service. Not from high prices. From unanswered phones.
What the 3 Companies That Answered Got Right
The 12% that could handle a potential install customer on the first call shared three traits.
Live answer within 3 rings
No phone tree, no hold music, no “press 1 for service.” A human picked up.
Real-time availability
The person who answered could see the schedule and offer specific appointment windows without putting the caller on hold or promising to call back.
Booked the appointment before hanging up
The call ended with a confirmed date, time, and service address. No follow-up required. These three capabilities do not require more staff. They require a system: either a dispatcher with real-time schedule access, or an automated intake system that captures the lead and books the slot.
How to Fix the Missed Call Problem for Under $500/Month
Three automations that address the missed call gap at any HVAC company size.
AI answering service ($149 to $300/month)
Services like Grasshopper or dedicated AI voice agents answer calls when your team cannot. They capture caller information, qualify emergency vs. routine, and send SMS notifications to your dispatcher or on-call tech.
Instant form response ($0 to $50/month)
HubSpot free tier or Zapier automation sends an immediate SMS or email when someone submits a service request on your website. Eliminates the 4-24 hour delay that kills form conversions.
Automated estimate follow-up ($0 to $169/month)
Jobber or HubSpot sends SMS and email reminders 24 hours and 3 days after an estimate is delivered. Recovers the 15-20% of estimates that go cold without systematic follow-up.
Total Cost
$149 to $519/mo
Expected Recovery
$3,000 to $7,000/mo
ROI
6x to 47x in 60 days
