In our guide to spiffs in home services, we defined a spiff as a flat bonus paid for a specific sales action, and we covered how to size one against an item's margin. This article goes deeper on HVAC alone, because HVAC is where spiffs are most common and where a badly designed spiff does the most damage.

HVAC owners don't hesitate on the question of whether to run spiffs. The real question is how to run them so your technicians recommend what the customer needs, and so the customer never feels like the tech was paid to push something. That comes down to a few design choices, and we'll walk through each one.

What Is an HVAC Spiff?

An HVAC spiff is a flat-dollar bonus paid to a technician for selling a specific item during a service call: a maintenance agreement, a surge protector, an indoor air quality product, a smart thermostat, or a higher-efficiency system. It's paid on top of the technician's base and commission.

That definition is simple. The design decisions behind it determine whether your spiff program grows the business or damages the trust your techs have built with customers.

The Biggest HVAC Spiff Mistake: One Spiff, One Item

The most common mistake we see is an owner who picks one item, puts a spiff on it, and tells the team to go sell it. It feels focused, and it creates exactly the behavior you don't want.

When there's only one spiffed item, every tech has the same incentive on every call: recommend that item. A homeowner with a brand-new thermostat still hears a pitch for a smart thermostat, and a home with a whole-home surge protector already installed still hears about surge protection. The tech isn't dishonest. The pay plan pointed them at one item, and the customer feels it.

The fix is to start with one objective and attach several items to it. If your objective is raising average ticket on service calls, the qualifying items might be:

Maintenance agreements
Surge protectors
Indoor air quality products
Smart thermostats
High-efficiency system upgrades

Each item gets its own spiff amount, set by that item's margin. Don't put every item on one flat rate. When a tech has several spiffed items, each one becomes its own runway. In one home the right recommendation is an air purifier, and in the next it's a maintenance agreement. The tech earns either way, so the tech can recommend whatever fits the house in front of them.

As starting ranges, our spiff guide puts maintenance agreements at $25–$75, smart thermostats at $10–$50, indoor air quality products at $10–$100, and high-efficiency upgrades at $200–$500. We'll show how to set your own numbers inside those ranges later in this article.

Spiffs Replace Commission on the Spiffed Item

With several items spiffed, the next question is how spiffs fit with commission. On any spiffed item, pay the spiff in place of the commission on that line item. The tech still earns commission on everything else on the ticket.

In our HVAC commission structure guide, we recommend hybrid technicians earn 3–15% of the service ticket. For the specific items you want to grow, the spiff takes over. On most add-ons, the spiff pays the tech more than the commission on that item would have, and that gap is exactly why the spiff moves behavior.

Hypothetical example: a tech on a 10% service ticket commission sells a $450 surge protector, and you spiff surge protectors at $75.

Commission the item would have earned: $450 × 0.10 = $45
Spiff the tech earns instead: $75
Extra the tech earns because the item is spiffed: $75 − $45 = $30

Commission gives the tech a reason to grow the whole ticket. The spiff gives them a reason to look for that item specifically, because it pays more than the item's commission would have.

How to Pay a Spiff on Replacement Leads

Commission and item spiffs cover what a tech sells on their own ticket. Replacements work differently, because the tech who spots a failing system often isn't the one who closes the sale.

For a technician who refers a replacement that someone else sells, we recommend paying 1–4% of the replacement, depending on the rest of your commission structure. Some guides recommend a flat $100–$200 per replacement lead. A percentage scales with the size of the job, so the tech's reward grows with the value they found.

Hypothetical example: a tech identifies a failing system that becomes a $12,000 replacement.

At 1%: $12,000 × 0.01 = $120
At 4%: $12,000 × 0.04 = $480

At 2%, the same tech earns $160 on an $8,000 replacement ($8,000 × 0.02) and $300 on a $15,000 replacement ($15,000 × 0.02). A flat $150 would pay the same for both.

One practical warning: attributing a replacement is hard when the tech identifies it on one ticket and the sale closes on a different ticket days later. Decide before launch how the referring tech gets credited, write it down, and make sure your tracking can follow the lead from one job to the next.

How to Spiff Good, Better, Best HVAC Options

Replacement leads raise a related design choice: which system the spiff should favor. When you present good, better, and best options, put the spiff on the better system.

The better system usually serves the customer better, and it usually carries more margin for you. Installation work commonly runs at 35–45% gross margin, and the higher tiers tend to sit toward the top of that range.

Hypothetical example:

Good tier: a $9,000 system at 35% gross margin = $9,000 × 0.35 = $3,150 gross profit
Better tier: an $11,000 system at 40% gross margin = $11,000 × 0.40 = $4,400 gross profit
Extra gross profit from the better tier: $4,400 − $3,150 = $1,250
A $150 spiff on the better tier costs $150 ÷ $1,250 = 12% of that extra gross profit

The tech earns more for presenting the better option, the customer gets the better system, and you keep $1,100 of the added gross profit ($1,250 − $150).

Maintenance Agreement Spiffs Should Always Be Running

Most spiffs in this article are tied to an objective you can change over time. Maintenance agreements are the exception. Keep the maintenance agreement spiff running all year, and pay it when the agreement is sold.

Agreements are recurring revenue and some of your highest-margin work, with gross margins commonly cited at 40–60% on the agreement itself. They also put your techs back in the customer's home on a schedule. That makes them a standing priority, and a standing priority deserves a standing spiff in the $25–$75 range.

Size Each Spiff Against the Item's Margin

We've covered which items to spiff and how the spiffs stack. The amount on each one comes down to one number you need for every item: its gross margin.

Our spiff guide walks through the five steps in detail: find the item's gross profit, size the spiff as a share of it, check what it does to labor cost on that ticket, compare items, and track how often techs sell the item before and after the spiff. For HVAC, two points matter most.

First, equipment-heavy items leave less room for a spiff than labor-heavy ones, so the same dollar amount can be cheap on one item and expensive on another. Pull the margins from your own pricebook before you set a number.

Second, measure the attach rate, meaning how often the item gets sold per qualifying call, before and during the program. You'll pay the spiff on sales that would have happened anyway, so the spiff only earns its cost if the attach rate goes up.

When to Pay HVAC Spiffs

Once the amounts are set, decide exactly when a spiff is earned and put it in a written policy. The ACCA's legal counsel recommends a written spiff policy that states when a spiff is earned, such as on job completion or customer payment.

Our recommendation:

Pay when the item is sold or when the job is completed. Pay on collection only if you're genuinely tight on cash, because waiting on payment delays the reward and weakens the incentive.
Financing doesn't change the answer. A financed sale is still a sale.
Claw back only when a replacement sale is canceled. Don't claw back maintenance agreement spiffs. Clawbacks erode the trust a spiff program depends on, so reserve them for the case where the replacement never happened.

The same ACCA guidance notes it's risky to withhold a spiff from a tech who leaves before payday when the sale was already completed. Write your policy so earned spiffs get paid.

How to Track HVAC Spiffs in Housecall Pro

All of these rules only work if spiffs are tracked automatically. Housecall Pro doesn't track spiffs on its own, so most shops end up on spreadsheets and paper forms.

TeamBuyIn connects with Housecall Pro and lets you mark any pricebook item as a spiff. Whenever that item appears on a technician's job, the spiff is calculated automatically, and you can switch an item's spiff on or off as your objectives change. Techs see their spiff earnings next to their commission, so they know what they earned on each job without asking the office. See how it works on our spiff management page.

Do HVAC Spiffs Count Toward Overtime?

One last rule applies to every spiff program, and HVAC owners run into it more than most trades. Your busiest weeks are often your overtime weeks, and those are the same weeks your techs are earning the most spiffs.

Spiffs count toward overtime. Under federal law, a bonus paid under an announced formula or promise is nondiscretionary, and nondiscretionary bonuses must be included in the regular rate used to calculate overtime for non-exempt employees, according to DOL Fact Sheet #56C. A spiff program you announce to your team fits that definition.

Your techs are almost certainly non-exempt. The ACCA's legal counsel notes that techs whose primary duties are installing and servicing systems are unlikely to qualify for the commissioned sales exemption, even if they earn spiffs, and should be paid hourly with time-and-a-half after 40 hours (ACCA).

Overtime is calculated by the week, not the pay period. Add up everything the tech earned in a single workweek, including spiffs, and divide by the hours worked that week. That's the regular rate. The overtime premium is half that rate times every hour over 40. The same ACCA guidance points out this applies weekly even if you run payroll every two weeks.

Hypothetical example: a tech earns $30 an hour, works 50 hours during a summer heat wave, and earns $300 in spiffs that week.

Straight-time pay: 50 × $30 = $1,500
Total pay including spiffs: $1,500 + $300 = $1,800
Regular rate: $1,800 ÷ 50 = $36 an hour
Overtime premium owed: 0.5 × $36 × 10 overtime hours = $180
Total owed for the week: $1,800 + $180 = $1,980

Here's what happens if the spiffs are left out of the regular rate:

Overtime premium on the hourly rate alone: 0.5 × $30 × 10 = $150
Total paid: $1,500 + $300 + $150 = $1,950
Underpayment: $1,980 − $1,950 = $30 for that week

Thirty dollars looks small. Repeat it every overtime week of the cooling season, across every tech on the team, and it becomes a wage claim.

Spiffs paid later still count. If a spiff can't be calculated until after payday, such as a replacement referral that closes weeks after the tech found it, DOL regulations let you leave it out of that week's overtime calculation until it's known. Once it's known, you owe any extra overtime for the week or weeks in which the spiff was earned (ACCA).

Check your state. Federal law sets the floor, and some states, California among them, have more generous overtime rules.

The practical fix is to run spiffs through payroll software that recalculates the regular rate every week, and to have your payroll provider or employment attorney review your spiff policy before launch. For more on how spiffs are taxed, see our spiff guide.

Set Up Your HVAC Spiff Program This Week

A strong HVAC spiff program has one objective, several qualifying items, an amount on each item that its margin can support, a standing spiff on maintenance agreements, a percentage for replacement leads, and a written policy for when spiffs are earned.

Your next step: pick the objective, list three to five items that serve it, pull each item's gross margin from your pricebook, and set a spiff on each one. Then measure the attach rate before you launch so you can prove the program worked.

Frequently Asked Questions About HVAC Spiffs

What is an HVAC spiff?
An HVAC spiff is a flat-dollar bonus paid to a technician for selling a specific item, such as a maintenance agreement, surge protector, or indoor air quality product. It's paid on top of the technician's base and commission.

How much should an HVAC spiff be?
Common ranges are $25–$75 for maintenance agreements, $10–$50 for smart thermostats, $10–$100 for indoor air quality products, and $200–$500 for high-efficiency upgrades. Set each amount against the gross margin on that specific item.

Should spiffs replace commission?
No. Pay spiffs on top of commission. Commission rewards everything on the ticket, and the spiff directs attention to the specific items you want to grow.

How much should a technician earn for a replacement lead?
We recommend 1–4% of the replacement for the technician who refers it, depending on your commission structure. A percentage scales with the size of the job.

Should you claw back HVAC spiffs?
Only when a replacement sale is canceled. Don't claw back maintenance agreement spiffs.

Do HVAC spiffs count toward overtime?
Yes. Announced spiffs are nondiscretionary bonuses, and federal law requires them to be included in an hourly technician's regular rate for overtime.

How do you track HVAC spiffs in Housecall Pro?
Housecall Pro doesn't track spiffs natively. TeamBuyIn connects with Housecall Pro, lets you mark pricebook items as spiffs, and calculates them automatically on every job.
