Dispatch, travel and seasonal workload for a small HVAC team

Build dispatch from the whole paid day

A small residential team can run out of schedulable time while its monthly sales target still looks modest. Repairs move across homes, installations may need both technicians together, and the working owner also reviews findings and coordinates work. Separately paid dispatch can collect job details and arrange access; it cannot supply the technician skill or physically perform the installation.

BLS describes technicians traveling between jobsites and sometimes working irregular schedules or overtime in peak heating and cooling seasons. That supports planning for variable workload, not a measured travel time or a national capacity ratio. Record the actual territory and work timestamps before increasing the forecast. Occupational scope

For employees covered by the federal hours-worked rules, intersite travel during the workday counts as work. Required travel after reporting for instructions or tools can also be part of the workday. Do not erase those hours merely because the customer does not see them. Ordinary commuting and other travel categories need separate treatment; state requirements also need a check for the real operation. 29 CFR 785.38

Reconcile the week before promising arrival windows

The existing case provides 80.0 available technician-hours a week from the working owner and one employee. This separate busy-week test schedules 24 repair calls and 1 replacement. A call needs 1.5 on-site hours, 21 driving minutes and 9 closeout minutes. The replacement uses 20.0 on-site technician-hours, with travel and preparation allocated separately.

The compact week has 0.0 unallocated hours after its protected block; only 70.0% of total time is on-site work. It is an exact illustrative fit, so any additional unknown task needs a new placement. The published monthly model instead applies 85.0% as a pooled billable-time assumption. Use either a reconciled explicit time ledger or that pooled allowance for the same activities. Adding driving to the model after its nonbillable deduction would count that loss twice.

Check both technicians and the installation clock

An aggregate weekly fit is only the first gate. The replacement must fit a real two-person slot with the required skills. This illustrative placement spreads its ten crew clock hours over two days. Service blocks include the stated driving and closeout. Each technician has an eight-hour workday, for 16 team hours on each of 5 days.

On Tuesday each technician spends four hours on installation/travel/preparation and completes two two-hour service blocks. On Wednesday and Thursday, one takes four service calls while the other takes three and the two-hour nonservice block. On Friday each takes three calls, one administration hour and one protected hour. Assign the administrative block to the person who actually performs it. This checks individual days as well as the total; it remains a test schedule, not a timed field trial.

Protected Thursday or Friday time cannot solve an urgent Monday interruption without moving work. Stage critical equipment, access and parts before the crew starts, and identify which later booking may move if an installation runs long. EPA certification must match covered refrigerant tasks; its apprentice exception requires close, continual supervision. An additional unqualified person does not automatically create another independent field slot. Skill boundary

Use travel to set territory and booking limits

If allocated driving rises from 21 to 45 minutes per call, the same week needs 89.6 hours: a 9.6-hour gap. With the installation and nonservice blocks retained, the wider route fits 20.0 calls, requiring 4 fewer calls. Four scattered appointments can consume the room needed for another four repair completions, even when the on-site work is unchanged.

Those removed calls represent $671.20 of weekly contribution at the case price/material/processing boundary, before fixed pay and overhead. This is an opportunity comparison, not a predicted loss of contracted customers or a new model expense. Confirm demand exists for the released compact-route slots before calling travel savings additional sales.

1. Qualify the request: record location, system, symptoms, access, known safety concerns and parts/equipment dependencies.
2. Assign the right block: use recent job-type durations and the actual crew skill, then include route legs and records.
3. Test the day: keep a feasible arrival window, emergency/return room and any two-person installation overlap.
4. Admit or move work: quote a later window or change the roster when the block will not fit; update the customer when a delay changes that promise.

Start with broad geographic zones, then measure the individual legs. A map radius alone misses traffic, bridges, supplier trips and customer availability. Keep denied or deferred requests in a separate log, so a low completed-job count is not mistaken for low incoming demand. Combine nearby appointments only when the customer and job priority permit it.

Price extra hours before using them as the release valve

For this comparison, assume the employee is covered by the general federal overtime rule, has already worked a 40-hour week and can take the entire 9.6-hour shortfall without an additional owner slot. At the case $34.00 hourly wage, treated here as the regular rate, the 1.50x multiplier gives $51.00 per overtime hour. Applying the case assumed 15.0% wider payroll loading produces $563.04 for the extra hours. Actual regular-rate components, exemption status and state rules require their own payroll check. Federal rate scope

Against the $671.20 contribution preserved by retaining those calls, that leaves $108.16 before incremental fuel, supplies outside the case scope, fatigue-related returns or other added costs. It also assumes the employee can absorb the work in real arrival windows. Extra cash or an overtime budget does not resolve a missing qualified two-person overlap.

Federal overtime workweeks stand separately; a quiet later week cannot be averaged with a long peak week to remove the relevant obligation. Workweek boundary This sensitivity stays outside the published model. A recurring overtime roster, new hire or subcontracting arrangement needs its own checked capacity and monthly cash revision.

Use seasonal demand to choose when work should happen

The case assumes 92.0 calls and 5.0 replacements in a mature neutral month, requiring 238.0 on-site technician-hours. Its monthly capacity is 346.7 available hours times the pooled billable share, or 294.7 on-site hours. The following months show the existing January-indexed seasonal assumptions after the opening ramp, rather than year-one results or observed local weather.

ENERGY STAR recommends spring cooling and fall heating checks before the busier seasons. Use that guidance to offer appropriate visit windows, then verify your local request history; a heat-pump or other equipment schedule may differ. It does not establish these month factors or a promise that the quiet season will supply enough maintenance sales. Preseason guidance

Unused February time cannot be stored for July. Agreement visits, replacement commitments, training and vehicle maintenance should be placed against the actual local demand calendar. Keep already-promised visits separate from discretionary new bookings. The monthly blend is useful for the financial case, but fractional job equivalents cannot replace a day-by-day roster with whole jobs and crew overlaps.

Keep a register that distinguishes delay from demand

Review at least the recent compact and wide-route weeks with the same job definitions. Recalculate blocks from actual records, then test the next week with real customer windows and a qualified crew. Saved time is useful only if it reduces paid commitments or serves feasible demand. Keep the unit-economics definitions and monthly cash scenarios attached to any proposed change, and use the financing evidence checklist when supplier payment or another vehicle becomes the next constraint.
