Technician depth: building a bench that survives February

Why depth matters more in hydronics

The short answer: fewer people can do the work, and each one carries more of your revenue. Losing one technician in a ten-person furnace company is a hiccup. Losing your only senior hydronic tech in a five-person boiler shop can stop installs for a season.

Depth also affects your marketing. There's no point in winning more boiler leads in October if the only people who can install them are booked until December.

Who this is for

• Owners who still do the hardest diagnostics themselves
• Companies that turned down profitable work last winter for lack of hands
• Shops planning a new service area or a second crew
• Businesses with one or two technicians who hold most of the know-how

What's included

• Capacity model: billable hours per technician per month, after travel, admin, callbacks and training, compared with the hours your sales plan needs.
• Skills map: a simple grid of who can handle which job types unsupervised: combi installs, cast-iron replacements, radiant, controls, commercial.
• Single-point-of-failure check: which jobs only one person can do, and what happens if that person is away.
• Hiring plan: which role to hire next, how to describe the job honestly, and what pay structure fits your margins.
• Training path: how apprentices progress, who mentors them, and what that costs in senior-tech hours.
• Seasonal plan: how to use slower months for training, ride-alongs and service visits.

The fee and scope are put in writing before the engagement starts.

A worked example

Suppose your four technicians each work 1,900 hours a year, but only 62% of those hours are billable once travel, shop time and callbacks are counted. That's about 4,710 billable hours.

Your plan for next year calls for 70 boiler installs at 16 hours each (1,120), 450 service visits at 1.8 hours (810), 260 repair and emergency calls at 2.5 hours (650), and around 1,500 hours of other work. That adds up to roughly 4,080 hours: it fits on paper. But installs and emergencies bunch up between October and March. If 65% of all those hours land in those six months, peak demand is about 2,650 hours against roughly 2,350 available. You're short about 300 hours exactly when it matters.

The answers might be moving service visits to spring, adding an apprentice to support installs, or capping marketing for installs in November. Put in your own figures; the seasonal split is usually what owners miss.

Timeline and how results are measured

The capacity model and skills map take two to four weeks. The hiring and training plan is a 12-month document reviewed each quarter. We measure:

• billable hours per technician per month, and the billable percentage
• jobs declined or deferred for lack of capacity
• the number of job types more than one person can handle
• time for an apprentice to reach unsupervised service visits
• technician turnover over the year

Mistakes to avoid

• Hiring after the season starts. A tech hired in November rarely becomes productive before the rush is over.
• Counting heads instead of hours. Five techs at 50% billable is less capacity than four at 70%.
• Leaving the owner as the only senior diagnostician. It caps growth and makes the business harder to sell.
• Ignoring provincial rules. Gas, pressure-equipment and trade certification are set provincially; check with the authority in your province or territory.

This area pairs closely with maintenance revenue and parts and emergency demand. The winter capacity guide shows the calculation in more depth.

Questions to answer before you hire

• Which job types did you turn down or delay last winter because only one person could do them?
• How many billable hours did each technician deliver in your busiest month?
• How much senior-tech time does an apprentice really need in their first year?
