Worked example No. 2 · Plumbing, heating, and HVAC · Southern Maine
Where a Southern Maine heating contractor's licensed hours actually go.
How a plumbing, heating, and air-conditioning contractor here actually runs, what Maine adds to the job, where the licensed hours go, and what I would put in place first. Checked against the statute. The questions at the end are where a conversation starts.
A worked example.
The firm, as it runs
One no-heat call, first ring to paid invoiceFive to sixty people, York or Cumberland. An owner who still estimates and escalates, a dispatcher, service technicians, an install crew, someone on parts, someone on the books. Two engines share one office, one set of licenses, one fleet, and one customer record: the service engine that absorbs no-heat, no-hot-water, leaks, and dead equipment, and the planned engine that installs and maintains and needs crew blocks, staged equipment, written proposals, permits, inspections, and rebate paperwork. Both spend the same licensed hours, and licensed hours are what the state says is short. One no-heat call crosses seven stations before it is paid, and four desks the firm does not own: the supply house, the town, Efficiency Maine, and the property manager's work order.
The firms say as much on their own pages. One in Scarborough answers the phone live around the clock, sells a membership plan to keep tune-ups on the calendar, prints its Fuel Board license number beside its services, and is hiring a warehouse parts runner next to three technician roles. One in Biddeford lists plumbing, heating, air conditioning, annual maintenance, geothermal, mechanical piping, and fuel delivery under one roof. One in Gorham names its state trade association and its Efficiency Maine partner status. None names the software it runs. Phone and web intake sit side by side everywhere. What the week looks like inside the office, who answers at night, where the license dates live, what happens when the part is not on the truck, is on no website. That is where the questions at the end of this page go. The other side of that no-heat call is the first worked example. The third does the same for a landscape firm.
What Maine changes
Verified at the statute, 5 September 2026Field-service software ships with a skills list and a calendar. Maine licenses the work by trade, by fuel, by authority, and by who is standing next to whom, and every town runs its own permit desk. Eight to check, with the statute beside each.
| The rule | The statute | What to check in your system |
|---|---|---|
| Trainee plumbers. A master or journeyman may not have more than 3 trainee plumbers under direct supervision; trainees and journeymen-in-training work only under it. | 32 M.R.S. §3301 · §3302 | That the board counts independently dispatchable plumbers, not heads, and shows which licensee each trainee rides with. |
| Gas authorities. A propane and natural gas technician holds authorities, not a trade: appliance connection and service up to 500,000 BTUs per appliance, large equipment above it, delivery, plant operation, tank setting and outside piping. A helper works only under the direct supervision of a technician with the same authority. | §18135 · §18136 | That the skills table carries the authority held and the job carries the appliance size. |
| Oil apprentices. An apprentice oil and solid fuel technician works only under the direct supervision of a master or journeyman holding the same or higher authority. Fuel Board and plumbing licenses run two years. | §18134 · Maine Fuel Board | That the supervising licensee and the expiry sit beside every apprentice on the schedule. |
| The electrical line. Oil burner technicians and gas installers are exempt from electrician licensing only within their own license; a plumber may reconnect conductors only to replace a water pump or water heater of the same or smaller size in a home. In South Portland any new wiring needs an electrical permit only a licensed electrician may take out. The state board's sunset for listed HVAC equipment under Exception No. 2 to NEC 210.8(F) expired September 1, 2026. | §1201-A · City of South Portland · Electricians' Examining Board | That "the tech can do the electrical" is not a dispatch rule, and that new wiring books an electrician and a permit before the crew date. |
| The $3,000 line. Any home construction contract over $3,000 in labor or materials must be written and signed by both parties, with the statute's provisions; a price change needs a written change order. The Attorney General reads this to include plumbing and heating work. | 10 M.R.S. §1487 | That the proposal template carries the provisions, and that the change order is a step in the job, not a phone call. |
| Rebates on the job. $1,000 per rebate-eligible outdoor heat pump unit at any income, $2,000 moderate, $3,000 low, with lifetime limits per housing unit; a Residential Registered Vendor; sized for at least 80% of peak heating load; installed to the checklist; claimed within 6 months of completion. Heat pump water heaters $1,150, no vendor registration. Biomass boilers a third of the cost up to $6,000. No current rebate for a standard oil or gas boiler. | Efficiency Maine, as posted 5 September 2026 | That eligibility, the sizing worksheet, the checklist, and the claim date sit on the job record. |
| No-heat. Where a landlord supplies heat it must hold 68°F at minus 20°F outside; the duty is the landlord's, and the contractor is the one who has to get there. Housing operators here class complete lack of heat as an emergency and take it by phone. Maine is the most heating fuel-dependent state, 56% of households on delivered fuel, so a no-heat call can be an empty tank. | 14 M.R.S. §6021 · Office of the Governor, 2024 | That no-heat is its own priority class, that intake captures the system and the fuel, and that the last delivery is an intake question. |
| Every town's desk. Saco: plumbing permits through the city's online permit portal at $10 per fixture, $40 minimum, $15 re-inspection; buried pipe inspected before it is covered; 24 hours' notice usually works, more recommended. York: a new online permit portal since October 27, 2025; allow 7 to 10 business days. South Portland inspects electrical, plumbing, and building work separately. The state's plumbing code is the 2021 UPC since January 1, 2022; the building code carries the 2021 IMC. | City of Saco · Town of York · City of South Portland · Plumbers' Examining Board | That permit and inspection state sit on the job by town, and that no crew date is promised before the permit. |

Two things the public record does say. The state's 2025 housing roadmap puts the construction labor shortage at its greatest in the specialty trades and names electricians, plumbers, and HVAC technicians. And heat pumps in Maine passed 100,000 in 2023 and 200,000 by March 2026 against a target of 275,000 by 2027, with the community colleges having trained 558 heat pump technicians by mid-2023. The scarce input in this business is a licensed hour.

The one I would test first in your office is the first: a dispatcher deciding who takes a no-heat call without one current view of who holds which license and authority, who is supervising whom, and what expires when. The second truck is where the hours go.
What I would put in place first
The ladderProcess first: one sendability matrix, each person's plumbing class, trainee status, fuel authorities, supervising licensee, electrical boundary, refrigerant card, and expiry, and a minimum credential rule for every job type; intake that always captures the system and the fuel; a diagnosis that ends in one of three states, done now, runner sent, or part ordered with the return slot held, and never in "unfinished"; permit and rebate checklists by town and job type. Then the settings you already pay for: credentials on each technician, required credentials on each job type, the permit number, inspection date, and claim deadline as fields on the job. Then an integration, if renewals have ever bitten: expiry alerts that project the loss of dispatchable capacity before it happens. Then a small tool, only if the platform cannot say who may legally take this call. AI on classifying the call and drafting the invoice narrative, with the rules deciding who is qualified and a person deciding what goes out.
Replacing the platform is the last hypothesis, not the first.
The morning board
ConceptA worked example.
How we would know it worked
Measured before, then afterFirst-visit completion, with the second-trip reasons counted
Licensed hours on licensed work, against hours on supply runs, waiting, and re-dispatch
Jobs waiting on a part with no return slot held
Permits approved and inspections passed before the crew dates that depend on them
Rebate claims filed inside the six months
Days from completion to invoice and from invoice to payment, property management work apart
Your records, before and after.
Before any of this is true of your firm
The questions- 1.
Walk me through the last no-heat call from the first ring until the invoice was paid; who touched it, and in which systems?
- 2.
When a call comes in, how does the dispatcher know who is legally allowed to take it; show me the view, not the policy.
- 3.
How many people on payroll are independently dispatchable today for plumbing, oil, gas, and heat pumps?
- 4.
What share of calls are finished on the first visit, and what are the reasons for a second trip?
- 5.
When a technician needs a part they do not have, what happens next, and is a return slot held before it arrives?
- 6.
Who owns permits and inspections, and what is the exception list by town?
- 7.
What actually happens between 5 p.m. and 8 a.m.?
We start with a conversation, not a contract.
