Key takeaways
- A good add-on solves a problem the technician can see on this visit. If you cannot point to a reason in the home, do not offer it.
- Keep a short, trade-specific add-on menu with set prices, so every technician offers the same things in the same way.
- Show evidence, give the price and accept the answer. One sentence, one question, no repeat pitches.
- Homeowners are spending: US households averaged $12,472 on home projects in 2025, up from $12,050 in 2024[1]. Relevant add-ons meet real demand rather than creating it.
What makes an add-on helpful rather than pushy
Add-ons have a bad reputation because some companies use them to pad invoices. Done well, they are simply good service: the technician notices something useful while already on site and offers to take care of it, saving the homeowner a second visit.
Three tests decide whether an add-on belongs in the conversation:
- Relevance: is there a visible reason in this home, today? A cracked gutter, a 20-year-old opener, a dryer vent full of lint.
- Evidence: can the technician show it, with a photo, a reading or the part itself?
- Fair price: is it on the menu at a set price, so the homeowner is not negotiating with the person in their kitchen?
If all three are true, mentioning the add-on is a service. If any is missing, leave it out.
Homeowners are open to the right suggestions. Angi found US households averaged $12,472 on home projects in 2025 and completed an average of 10 projects, up from 9[1].

The add-on menu by trade
Keep the menu short. Five to eight items per trade is enough. Each needs a trigger (what the technician sees), the evidence to show and a set price.
| Trade | Add-on | Trigger the tech sees | Evidence to show |
|---|---|---|---|
| HVAC | Duct sealing in accessible areas | Disconnected or leaking ducts, uneven room temperatures | Photos of gaps; temperature readings by room |
| HVAC | Upgraded media filter | Dirty coil or blower, dusty home, allergy concerns raised by homeowner | The old filter and coil photos |
| HVAC | Carbon monoxide alarm | Gas furnace or water heater and no working CO alarm nearby | Alarm test result |
| Electrical | Whole-home surge protection | No surge device on the panel; sensitive electronics or recent outages | Panel photo |
| Electrical | GFCI protection | Unprotected outlets in bathrooms, kitchen, garage or outdoors | Tester result |
| Roofing and gutters | Gutter guards | Gutters packed with debris, overflow staining | Photos of the gutter |
| Garage doors | Opener replacement with photo-eye sensors | Old opener with no sensors or failed auto-reverse | Test result and opener label |
| Appliance repair | Braided washer hoses or dryer vent cleaning | Bulging rubber hoses, lint-packed vent | Photos |
| Cleaning | Inside oven, fridge or windows | Homeowner mentions them or they are clearly overdue | Before photo |
| Pest control | Exclusion work | Gaps around pipes, vents or doors where pests enter | Photos of entry points |
| Landscaping | Aeration and overseeding | Thin turf, compacted soil | Soil probe, photos |
The table is a starting point. Build your own menu from the add-ons your team can deliver well and that your customers actually buy.
The facts behind common add-ons
Some add-ons are backed by clear, public guidance, which makes them easier to explain honestly.
- Duct work and installation quality: ENERGY STAR says sealing and insulating ducts can improve heating and cooling efficiency by as much as 20%, and that improper installation can reduce system efficiency by up to 30%[2]. Say "as much as" and "up to", and do not promise a specific saving in a particular home.
- Carbon monoxide alarms: more than 400 Americans die each year from unintentional carbon monoxide poisoning not linked to fires, and more than 100,000 visit an emergency department[3]. A working CO alarm near sleeping areas in a home with gas appliances is a genuinely useful add-on.
- Garage door openers: the federal entrapment protection standard applies to residential openers made on or after January 1, 1993[4]. A very old opener may predate it, and an opener that fails the auto-reverse test needs attention either way.
- Electrical safety: there were an estimated 344,600 residential building fires in the US in 2023[5]. Surge protection and GFCI and AFCI protection are standard recommendations, but keep the conversation factual rather than alarming.
How to offer an add-on in one minute
Show the evidence
"Can I show you something? This is your dryer vent. It's mostly blocked with lint."
Explain what it means
"That makes the dryer run longer and work harder. Lint build-up in vents is also a fire risk."
Offer the fix with the price
"I can clean the vent while I'm here. It's on our price list at a set amount and takes about 30 minutes."
Ask once
"Would you like me to do that today, or would you rather leave it?"
Accept the answer and record it
If they decline, note it on the invoice as a recommendation, so it is on record and they have it for later.
The last step matters. A declined recommendation written on the invoice protects the homeowner and the company, and many homeowners call back later once they have thought about it.
Pricing add-ons so the conversation stays simple
Set prices are what make an add-on offer feel like service rather than negotiation. When the technician can say "it's a set price on our list", the homeowner does not have to wonder whether the number was made up on the spot, and the technician does not have to haggle.
- Price each add-on from its real time and materials, including any extra drive or setup time, plus your normal margin.
- Show the price on a printed or tablet menu the homeowner can read for themselves.
- Apply member discounts in the same way as for any other work, if you run a maintenance plan.
- Review add-on prices twice a year, when you review the main price book.
- Avoid bundles that hide the price of each item. If you offer a bundle, list what each part would cost on its own.
Training technicians to spot triggers
Most technicians already notice these conditions; they just do not mention them. Training is mainly about permission and wording.
- Walk through the menu with the team and agree the trigger and evidence for each item.
- Show photos from real jobs: a clogged vent, a worn hose, a missing CO alarm, a packed gutter.
- Role-play the one-minute offer until it sounds like a normal part of the visit.
- Practice the "no problem" response to a decline, so nobody pushes after a no.
- Ride along or review job photos monthly, and share examples where an add-on helped a customer.
Technicians who dislike selling often find this approach easier, because they are reporting what they see rather than making a pitch.
When to offer, and when not to
Timing changes how an add-on feels. Good moments:
- While showing the main diagnosis, if the add-on is related, such as a surge protector during a panel repair.
- At the end of the job, while reviewing the invoice, for unrelated but visible issues.
- During maintenance visits, which are designed for exactly this kind of check.
Bad moments:
- Before the main problem is fixed, especially in an emergency. A homeowner with no heat in January does not want to hear about filters.
- When the homeowner is clearly stressed about the cost of the main repair.
- On every visit, for the same item, after they have already said no.
Avoiding pressure with incentives
Many companies pay technicians a small spiff on add-ons. That is fine, but design it so it rewards good judgment.
- Pay on add-ons that pass the three tests, and spot-check a sample with photos each month.
- Track add-on acceptance alongside complaints and cancellations. A technician with very high acceptance and complaints is pushing.
- Never set add-on quotas per visit. Quotas guarantee irrelevant offers.
- Recognize technicians who note honest recommendations that customers act on later.
Our article on selling without pressure covers the broader habits. If add-ons are sold in the home and add up to a larger sale, check whether the FTC Cooling-Off Rule applies; see our guide to the Cooling-Off Rule.
Measuring add-ons
- Offer rate: share of visits where at least one add-on was offered with evidence attached.
- Acceptance rate: add-ons sold divided by add-ons offered.
- Revenue per visit from add-ons, by trade and technician.
- Callbacks or complaints related to add-ons.
- Later uptake: declined recommendations that turned into jobs within six months.
Example: a menu replaces improvisation
Example (fictional): A combined HVAC and electrical company let each technician suggest whatever they thought of. Some offered nothing; one offered five items on every visit and drew complaints. The company built a menu of seven add-ons with triggers, evidence and set prices, and added a "recommendation declined" line to invoices. Within two months, the share of visits with a relevant offer rose from about one in six to about one in three, average add-on revenue per visit increased, and complaints about add-ons dropped to zero. The technician who had been over-offering became one of the best performers once he was limited to items with a visible trigger.
Frequently asked questions
How can technicians offer add-ons without being pushy?
Only offer add-ons with a visible reason in the home, show the evidence, give a set price, ask once and record the answer as a recommendation if the homeowner declines.
What are good add-ons for HVAC technicians?
Duct sealing in accessible areas, upgraded filters, carbon monoxide alarms where there are gas appliances, and condensate or drain line protection, each offered only when the technician sees a reason.
Should technicians earn spiffs on add-ons?
Small spiffs are common. Pay only on relevant, evidenced add-ons, avoid per-visit quotas and track complaints and cancellations alongside acceptance.
When should an add-on not be offered?
During an emergency before the main problem is fixed, when the homeowner is clearly stressed about cost, or repeatedly after a clear no.
