An HVAC comfort advisor is hired to write sales, and HVAC sales commission is the piece of the paycheck tied to that work: a commission plan gives the advisor a share of each sale they write, with a base wage, a draw, or nothing under it.
The mix — the percentage, what it applies to, how leads are credited — is the employer's to write.
No government source our research found publishes typical percentages; this page explains the structures and the closest federal data.
Base, draw and commission
A comfort advisor's plan combines up to three parts, and the employer decides which parts appear and in what proportions — one reason two advisors at different shops can write the same sale and take home different checks.
Comfort advising is one seat in the trade; the HVAC sales career guide maps the others.
This page stays on the paycheck.
The base is a guaranteed wage — hourly or salaried — paid for hours worked regardless of what sells.
It carries the advisor through canceled appointments, slow months and training weeks, and it is the part of the plan that never depends on what sells.
A draw against commission looks similar and works differently: it is an advance paid each pay period against commissions the advisor has not yet earned, and the commissions that come in later pay it back.
Whether a draw is a true advance — reclaimed out of future commissions — or a straight guarantee that is never reclaimed is written in the plan, and the difference decides what a bad month actually costs you.
Ask which one you are being offered before you accept anything.
The commission itself is the share of each sale.
What number it multiplies, which lines of the contract count toward it, and when it is paid — weekly, monthly, or after the job is completed and booked — are all plan details, and every one of them moves the paycheck.
Spiffs — per-item bonuses on a specific product or action — can sit on top of the plan rather than inside it.
How the trade splits these parts — how common full commission is, what a typical base pays, what a normal percentage looks like — is not something our research found published anywhere: no primary source, government or credential body, publishes comfort-advisor commission structures; the numbers quoted around the industry come from consultants and member surveys our research could not verify.
The written plan in front of you is the only version that counts.
Percent of the sale vs. percent of the margin
Before the percentage, one line in the plan decides how it pays: the one that answers — commission on what number?
A plan can run its commission on one of two bases, and the two produce different paychecks from the same contract.
Under a percent-of-sale plan, the commission multiplies the gross sale — the invoice total the customer pays.
Every dollar on the contract, at least on the lines the plan counts, feeds the calculation.
Under a percent-of-margin plan, the commission multiplies the gross margin — what remains of that same invoice after the company's direct costs for the job, such as equipment, materials and install labor.
The commission then rises and falls with the profit the job produces, not with its sticker price.
The two bases produce numbers that do not translate across shops.
The margin is a smaller number than the sale, so the same contract pays less per percentage point under a margin plan — which means a lower percent of gross can out-pay a higher percent of margin, or the reverse, depending on what each company's costs run.
A percentage quoted in an interview tells you little until you know the base it multiplies.
The base a plan chooses is an incentive choice: commission on the sale rewards ticket size, and commission on the margin rewards jobs that keep more of their price after costs.
What that means for you is practical, not philosophical: know which lines the plan adds up, how discounts, warranty work and callbacks are treated, and who at the company computes the number your percentage rides on.
Company leads, self-generated leads and tech-turnover leads
A commission rate tells you half of the economics.
The other half is what lands in the calendar, and not every appointment is the same kind of opportunity.
Company leads arrive through the contractor's own marketing — advertising, promotions, estimate requests from the website and phone lines — and reach the advisor's schedule as homeowners who are already engaged with the company about a replacement.
Self-generated business is the advisor's own doing: referrals, past customers kept warm, neighborhoods worked, relationships that outlast the install.
A plan can treat both sources identically, or it can credit them differently — a different rate, a different split, or commission that counts only on certain sources — and where it does, the split is written into the plan.
A split of that kind allocates two costs: marketing spend is the company's money; self-generated work is the advisor's time.
How any given shop draws that line is its own choice — our research found no published data on how shops set it, so it is a question for the plan.
Tech-turnover leads sit between the two.
A service technician on a repair call finds equipment at or near replacement, tells the homeowner what they found, and hands the replacement conversation to sales; the advisor takes the appointment from there.
Where these leads come from and how the handoff works is the comfort advisor role page's subject — what matters for pay is that the plan says whether they are credited as company leads, as the advisor's own, or in a category of their own.
Comparing offers across shops therefore takes two numbers, not one: the rate and the flow.
A plan that pays a higher rate on a thin calendar can lose to a lower rate on a full one — which is why the questions below include what a typical week of appointments looks like, not just what the percentage is.
What top HVAC sales reps earn
Start with what our research did not find.
In the federal sources we checked — the OEWS occupation list and the BLS Employment Projections table — no series exists for comfort advisors or for HVAC sales under that name, and the title has no Standard Occupational Classification of its own.
No verified comfort-advisor salary can be quoted from them, and “top advisor” earnings are not a cut those programs publish.
The closest category is SOC 41-3091, Sales Representatives of Services — the sales occupation BLS finds the most of inside NAICS 238220, plumbing, heating, and air-conditioning contractors.
In the May 2025 data (released May 15, 2026), that cut shows 24,510 jobs, an annual median of $79,530, an annual mean of $88,680, a 10th percentile of $42,710 and a 90th percentile of $139,990.
Why this category and not another sales code: wholesale and manufacturing sales reps — the code that fits distributor and manufacturer reps — number 2,830 in the same industry, and BLS publishes no figure for retail salespersons in the industry.
Contractors employ service-sales reps, and that is what the category holds.
Read the label before the number.
The category covers all sales reps of services at plumbing and HVAC contractors, both trades together — not comfort advisors alone — and its commission-heavy pay varies widely, so treat each figure as a category benchmark rather than a title benchmark.
The 90th percentile is the closest published marker for high earnings inside the category; it is not a comfort-advisor leaderboard.
Three measurement notes travel with every number: the figures count wage-and-salary workers only, so self-employed reps sit outside them; the survey includes commissions, production bonuses and incentive pay in the wages it reports; and it excludes overtime pay, shift differentials, non-production bonuses such as sign-on bonuses, and benefits.
Our HVAC sales salary data page carries that same category benchmark — the NAICS 238220 snapshot behind the figures above, with the measurement caveats spelled out.
Median vs. mean, category vs. title
Questions to ask before you take the job
Every structure on this page is knowable before you sign, and the written plan is the thing to know.
Ask the questions below, and get the answers in the document rather than in the conversation.
One question belongs to wage law.
Under the Fair Labor Standards Act, the Section 7(i) overtime exemption reaches commissioned employees of a retail or service establishment only when their regular rate is more than one-and-a-half times the minimum wage and more than half their pay over a representative period of at least one month is commissions.
Whether a given shop's plan sits inside the exemption is a determination to confirm rather than assume — ask how overtime is computed on your plan, and read the guide to tech commission for how commission runs through the overtime rules.
- Is there a written pay plan, and does it state the percentage, the base it multiplies — gross sale or margin — and when commission is paid?
- Is the base a guaranteed wage for hours worked, or a draw — and if it is a draw, is it repayable from future commissions?
- Which lines of the contract earn commission — equipment, labor, maintenance agreements — and how do discounts, warranty work and callbacks affect the number?
- Does the plan pay one rate on every sale, or does the rate change by lead source — company leads, self-generated work, tech-turnover appointments?
- What does the appointment calendar actually look like — how many in-home estimates a week, and what did a slow-season month pay the advisors already on the plan?
- How is overtime computed on the plan, and does the shop treat it as exempt under FLSA Section 7(i)?
- Do spiffs stack on the plan, and on which products or actions?
The answers tell you what a strong month and a slow season each look like under the plan — the two halves of the year that decide whether an offer works for you.
