HVAC sales commission, explained without the sales pitch

One of four ways, and you need to know which one you are on before you take the job. A percentage of the job's revenue is the simplest. A percentage of the job's gross profit is increasingly common and pays you on margin instead of sticker price. A flat dollar amount per system installed is used at high-volume replacement shops because it is easy to forecast. And a sliding scale ties your rate to how close you sold to book price, so discounting costs you twice. On top of whichever base you are on sit spiffs — memberships, indoor-air-quality add-ons, thermostats, surge protectors — that are usually separate line items.

It varies enough that any single number is misleading, but the ranges reps and managers commonly describe are roughly 6% to 12% of the job's revenue on revenue-based plans, or roughly 20% to 40% of gross profit on margin-based plans. Flat per-system plans commonly land somewhere in the low hundreds to under a thousand dollars per installed system, often tiered by efficiency or by good-better-best level. Canvassers and setters are paid differently — usually an hourly base plus a set fee per appointment that actually sits, plus a bonus if that door turns into an installed system. Treat all of these as typical, not universal, and verify against the actual written plan.

Revenue-based pays you a percentage of what the customer signs for, so a $14,000 job at 8% is $1,120 whether the install went smoothly or went sideways. Gross-profit-based pays you a percentage of what is left after equipment, materials, labor and sometimes financing fees, so the same job can pay very differently depending on how it actually got built. Margin plans usually pay more on a clean, well-sold job and less on a discounted or difficult one, and they cannot be finalized until job costing closes — which is why margin-plan reps often wait longer to get paid and occasionally see an adjustment after the fact.

Not really, and it is worth being honest about that because it is the biggest structural difference between HVAC and alarm sales. Maintenance memberships are the closest thing this trade has to recurring revenue — the customer pays monthly or annually for seasonal checks, priority service and a repair discount — but the rep is almost always paid a one-time spiff for selling one, commonly somewhere in the tens of dollars, not an ongoing residual. Some companies pay a small renewal bonus. If you want true recurring monthly revenue on your own book, that lives in alarm and monitoring sales, not HVAC.

More things than new reps expect. Cancellations are the big one: sales made at a customer's home are generally subject to a federal cooling-off rule giving three business days to cancel, and many states add their own protections — confirm the current rule and your state law with your company. Beyond that: financing that never funds or a customer who does not qualify, uncollected final balances, jobs that blow their install budget on a gross-profit plan, callbacks and warranty rework at shops that charge them back, price concessions given later to resolve a complaint, and permit or inspection failures that require redoing work. A good comp plan states each of these in writing.

Rarely at the signature. The most common pattern is payment after the system is installed and invoiced, on the next one or two pay cycles, which for a job sold in the peak of summer can still mean weeks. Some companies split it — part at sale, part at install — and gross-profit plans generally wait for job costing to close, which can run several weeks past the install date. Canvasser set fees usually pay much faster, often on the next payroll after the appointment sits. The gap between selling and getting paid is why tracking each deal to its own payout matters more in this trade than in fast-cycle verticals.
