Every new HVAC client arrives with a window of social permission to ask questions. That window closes fast. Once the relationship is established, “What’s the age of your system?” or “Is there a gate code?” starts sounding like questions you should already know the answer to. The first call and the first visit are when you capture every piece of information you’ll rely on for the next five years.
Done well, onboarding takes 3-5 minutes of additional conversation during the first visit and eliminates 10-15 minutes of re-asking on every future visit. The math compounds fast.
What to Capture, Organized by Record
Every client in your CRM should have three interconnected records: the client, their equipment (possibly multiple units), and the access context. The onboarding checklist is simply making sure all three are filled out.
Client Record
- Full name (and name pronunciation if non-obvious — write it phonetically in the notes field)
- Service address (with unit/suite if applicable)
- Billing contact — if different from service contact; rental properties and commercial clients often have separate billing
- Preferred contact method — call, text, or email. Clients who get texted when they prefer calls feel ignored; clients who get called when they prefer texts feel interrupted.
- Primary phone (ideally both mobile and landline if they have one)
- Email address (verified — ask them to spell it out)
- Referral source — “How did you find me?” Always ask. Answers cluster into 4-6 categories (Google, neighbor referral, specific neighborhood group, Yelp, existing client’s recommendation, etc.).
Access Record
This is the most neglected and most valuable onboarding field. Access notes live on the client record but come up on every visit.
- Gate code (commercial, gated communities, HOA properties)
- Lockbox code or location
- Preferred entry door — the customer may want you going through the garage, not the front
- Pet warnings — breed and demeanor, not just “there’s a dog.” “Border collie, friendly but jumps” is useful. “There’s a dog” is not.
- Parking notes — especially in dense urban or HOA-restricted areas
- Tenant vs owner context for rentals — who has authority to approve repairs?
- Hours the property is accessible — for vacation homes, commercial spaces, secondary properties
Equipment Record(s)
Every HVAC unit on the property gets its own record. Most single-family residences have 1-2 units; commercial spaces can have several.
For each unit:
- Type — central AC, heat pump, mini-split, furnace, boiler, rooftop package, refrigeration rack
- Location on property — “attic furnace,” “side-yard condenser,” “basement boiler”
- Manufacturer (Carrier, Trane, Lennox, Daikin, Goodman, etc.)
- Model number (from the nameplate)
- Serial number (from the nameplate)
- Year of manufacture (often encoded in the serial number if not explicit)
- Refrigerant type (R-410A, R-22, R-454B, R-32 — critical for compliance framework detection)
- Full charge in pounds (from the nameplate or manufacturer specs; revisit if the line set was modified)
- Tonnage / capacity
- Photos of the nameplate — the single most valuable field you can populate. Five seconds to snap; saves every future trip from guessing.
- Known issues or service history from prior technicians, if the client knows any
The Question That Pays for Itself
Ask every new client: “Is there any other HVAC equipment on the property I should know about? Mini-splits, a secondary unit, a wine fridge, refrigeration, a heat pump water heater?”
This single question regularly surfaces a second or third piece of equipment that you would have discovered eventually — but asking on the first call means you enter those units into the system now, while the client is thinking about it. Future tune-ups, repair calls, and PM contracts all have the full picture from day one.
Business Context to Capture
How They Found You
Referral source is business intelligence you can act on. After 6-12 months of onboarding, you’ll see the pattern clearly:
- 40% come from existing client word-of-mouth → referral rewards are worth investing in
- 20% come from Google Maps → your Google Business profile and reviews matter
- 15% come from a specific neighborhood Facebook group → engage there more deliberately
- 15% come from Yelp → maintain your Yelp presence
- 10% come from paid advertising → is that channel profitable?
You cannot optimize what you do not measure. Track every source.
Priority Tier
Not every client is equal. Some factors that affect how you prioritize:
- Contracted clients (maintenance agreement) → priority dispatch
- Commercial clients with critical cooling (restaurants, data closets, medical) → higher urgency
- High-lifetime-value residential clients → discretionary priority
- New clients → slightly longer queue acceptable until the relationship is established
A simple priority flag on the client record makes dispatching during a heat wave obvious rather than stressful.
Payment History
Over time, the client record should accumulate:
- Payment reliability (on time, occasional late, chronic late)
- Preferred payment method (check, card, autopay on contract)
- Open invoices (should be visible the moment you pull up the client)
The Onboarding Conversation Script
A natural, non-intrusive way to gather everything on a first visit:
Tech arrives, introduces himself, inspects the failed unit, gives the diagnosis and estimate, client approves.
During the repair: “While I’m working on this — let me get your info set up in my system so next time we can move faster. Can you spell your email for me?”
Pulls up the CRM, creates a client record.
“You prefer calls, texts, or emails for scheduling?”
“Great. Any gate code or anything I should know about accessing the property?”
“How about pets — anything I should expect?”
“Mind if I snap a photo of the nameplate for my records? That way if you call in a year with a weird noise, I’ve got the model already.”
Snaps photos of all accessible nameplates.
“Anything else on the property? Mini-split, another unit, anything?”
“How did you find me, by the way? Always curious what’s working.”
That’s it. 3-5 minutes, conversational, no clipboard, no form. The client doesn’t notice the intake is happening; you end the visit with a complete record.
What Onboarding Enables
A well-onboarded client means every future interaction is faster:
- They call with an issue → you pull up the client in 2 seconds, see the equipment, see the service history, see the access notes, and can quote a visit window confidently.
- You roll up to the property → gate code and pet warning are already on your phone.
- You diagnose the issue → the refrigerant type, full charge, and equipment history drive automatic leak rate calculations and compliance checks with no manual lookup.
- You estimate the repair → previous invoices and pricing context are already visible.
- You close out the job → the client’s email is on file and the invoice emails itself.
Onboarding is a 5-minute investment that pays back for the life of the relationship.
How FieldPad’s CRM Makes Onboarding Permanent
FieldPad is an all-in-one HVAC CRM built for solo technicians — clients, jobs, scheduling, estimates, invoices with signatures, inventory, and equipment history, all on an iPhone that works offline. Client, equipment, and access records live on the same screen, so onboarding once means the context is there for every future visit.
When you onboard a new client in FieldPad:
- Client record captures contact info, billing contact, preferred contact method, referral source, and priority tier.
- Access notes field lives on the client record and displays automatically on every scheduled appointment for that client.
- Equipment profiles — multiple per client — store make, model, serial, year, refrigerant type, full charge, tonnage, and photos of the nameplate.
- Referral source tracking produces a running report of which marketing channels produce paying clients.
- Service history accumulates automatically as you log jobs — no separate data entry step.
- Priority flags surface contracted clients and commercial-critical accounts in scheduling view.
Because the CRM runs offline, you can onboard a client in a basement, a rural driveway, or a mechanical room with no signal — and the data syncs the moment you’re back in coverage.
Key Takeaways
- The first call is the only socially-acceptable window to ask everything you’ll want to know for the next five years.
- Capture three records on each new client: client, access, and equipment (often multiple).
- Ask about other equipment on the property — the question regularly surfaces hidden work.
- Track referral source — it’s the only way to optimize your marketing spend.
- Photograph every nameplate during the first visit. Five seconds per photo; lifetime value.
- Flag priority tier so dispatching during a heat wave is obvious.
- Use a CRM where client, equipment, and access live on one record so the context you captured stays useful.
