HVAC Calls Per Truck Per Day: Optimizing Your Fleet's Revenue Capacity

Calls per truck per day (CPTD) is one of the most important operational KPIs in the HVAC industry. It measures how efficiently your fleet is being utilized and directly correlates with revenue per truck. Top-performing HVAC companies consistently run 4 to 5 service calls per truck per day, with an average ticket of $350 to $500 per call. That's $1,400 to $2,500 in daily revenue per truck. Companies running below 3 calls per truck per day are leaving significant capacity and revenue on the table.

Why Trucks Sit Idle: The Phone-to-Schedule Pipeline

When an HVAC company's CPTD is below benchmark, owners typically assume they need more marketing to generate demand. But in most cases, the demand exists — it's just not making it onto the schedule. The bottleneck is the phone-to-schedule pipeline: calls come in but don't get answered, voicemails don't get returned in time, and appointments don't get booked. A truck that could run 5 calls today runs 3 because 2 potential appointments were lost to missed phone calls yesterday.

Calculating Your CPTD Gap

To calculate your CPTD gap, take your monthly service calls and divide by your number of trucks and working days. If you run 3 trucks and complete 180 service calls per month over 22 working days, your CPTD is 2.7. The benchmark of 4.5 means you have capacity for 297 calls per month — a gap of 117 calls. At $400 per service call, that gap represents $46,800 in monthly revenue your fleet could generate if you could just fill the schedule.

• Track total service calls completed per month
• Divide by number of active service trucks
• Divide by working days to get CPTD
• Compare to 4-5 benchmark for service calls
• Multiply gap by average ticket for revenue opportunity

Filling the Schedule Through Phone Coverage

HVAC companies that implement comprehensive phone answering — through AI or additional staff — consistently see their CPTD increase by 1 to 2 calls per truck within 90 days. That improvement comes entirely from capturing calls that were previously going to voicemail. No additional marketing spend required. The demand was always there; it just wasn't making it through the phone system to the scheduling board.
