Setting up GoHighLevel for HVAC businesses in Australia is a different job to setting it up for a sparkie or a plumber, and the reason is seasonality. Your phone barely rings in September, then a heatwave lands in late November and you take a year's worth of calls in ten days.

Most air conditioning operators I work with build for the surge and ignore the trough. That is backwards. The build that actually changes the P&L is the one that captures every call during the peak and puts a machine to work in the quiet months so the peak starts earlier and lasts longer.

Why seasonality breaks a normal HVAC CRM build

A pest control business gets steady enquiries all year. A builder works off a slow, high-value pipeline. Air conditioning is neither — it is a demand curve with a cliff in it.

The Bureau of Meteorology defines a heatwave as three or more days in a row where both daytime and night-time temperatures are unusually high for that location and time of year. That three-day window is roughly when your inbound volume triples and your install diary fills.

The operational consequence is simple: during the surge you cannot answer the phone, and during the trough there is nothing to answer. A HighLevel HVAC CRM build has to solve both problems with the same asset base.

What you are actually building

Six systems, in this order of return:

• Surge capture — missed call text-back, after-hours handling, instant speed to lead
• Quote follow-up — the sequence that closes jobs you already priced
• Maintenance agreements — recurring products that fill autumn and spring
• Pre-season reactivation — timed campaigns before summer and before winter
• Long-horizon reminders — warranty checks and annual services on 12- and 24-month Wait steps
• Review capture — triggered on install completion, not on invoice payment

Capturing the surge without losing calls

In a heatwave your customer is hot, uncomfortable and impatient. They do not leave a voicemail and wait. They ring the next three companies on the map pack.

Missed call text-back is the single highest-return switch

HighLevel ships this natively — you can toggle it on under Settings → Business Profile, or build it as a Workflow with a Missed Call trigger for more control over branching and tags. For an air conditioning business I always build the Workflow version, because you want different copy for business hours versus 9pm on a Saturday.

The message needs to acknowledge the miss, sound like a human, and give one frictionless next step — usually a Calendars link for a site assessment. Our full missed call text-back build walks through the LC Phone configuration and the exact copy.

Every missed call during a heatwave is a job that went to a competitor, and the recovery costs you nothing in extra ad spend.

After-hours and overflow

Add a Workflow that checks the time of day and routes accordingly. Inside business hours, the text-back promises a callback within the hour and creates a task. Outside hours, it books straight into a next-morning Calendars slot.

Conversation AI handles the middle ground — qualifying whether it is a repair, a service or a new install, capturing the suburb and the system type into custom fields, then handing to a human. It is not there to sell. It is there to stop the lead going cold between 7pm and 7am.

Speed to lead when five competitors were also called

I will not quote you a study here, because the honest answer is that the credible speed-to-lead research is American, B2B and not about tradies in a Brisbane summer. But the mechanic is obvious to anyone who has run a service business: the first company that responds with a real time slot usually gets the job.

So build for it. Form submission and inbound call triggers should fire an SMS within seconds, not minutes, and a pipeline opportunity should be created automatically so nothing depends on someone remembering.

The quote follow-up sequence that wins jobs you already quoted

Most air conditioning operators quote far more than they close, and the gap is almost never price. It is silence.

Build one pipeline with stages that reflect how the work actually moves, and let Workflows push opportunities between them.

Nothing here is exotic. The discipline is that the quote-sent sequence has a Goal event so the moment someone accepts, the chasing stops. We detail the copy and the Wait-step spacing in the quote follow-up workflow guide, and the estimate mechanics in the proposals and estimates setup.

Maintenance agreements: turning installs into recurring revenue

This is the piece that fixes the quiet season, and almost nobody builds it properly.

A one-off split system install is a transaction. A maintenance agreement — annual or six-monthly service, filter clean, coil check, priority booking in summer — is an annuity that also gives you a reason to be in front of the customer before the rush.

In HighLevel you set this up as a recurring product with a subscription price, sold through a payment link or an accepted estimate. The subscription creates the billing; a Workflow with the purchase trigger applies a maintenance-member tag and starts the service scheduling sequence.

Sell the agreement at install completion, when satisfaction is highest and the unit is visibly new — not twelve months later when the customer has forgotten your name.

Then use the tag everywhere: members get priority booking messaging in January, a different pre-season email, and never receive the "we haven't seen you in a while" reactivation.

The pre-season campaign calendar for Australian summer and winter

Australia gives you two shoulder seasons and you should be running a campaign into both. The trick is timing — you market before the weather turns, not during, because during is when your diary is already full and your prices are firm.

Adjust the months for your climate zone — a Cairns operator and a Hobart operator are running almost inverted calendars. Store the dates as custom values so you update the campaign timing in one place rather than editing eleven Workflows.

Warranty and annual service reminders on long horizons

HighLevel Wait steps handle multi-year horizons perfectly well, and this is where an air conditioning business quietly out-earns its competitors. A contact who installed in 2024 should be hearing from you on schedule, forever.

Drive all of it from an install_date custom field rather than the contact creation date, so migrated records behave correctly. The mechanics are the same as any service reminder workflow, just on a longer clock.

Reviews, compliance, and where HighLevel stops

Capture reviews at install, not at invoice

Trigger the review request when the job is marked complete and the unit is running cold, not when the invoice clears. The gap between those two events is where goodwill evaporates.

Get the SMS compliance right first

Australia's Spam Act 2003 requires consent, clear sender identification and a functional unsubscribe on every commercial message, and the ACMA enforces it. Past customers generally fall under inferred consent for related services, but the ACMA's stated preference is express consent — capture it at the quote stage.

Reactivation campaigns are exactly where tradies get caught, so read our notes on Australian SMS compliance in HighLevel before you send to a three-year-old list.

HighLevel is the sales and marketing layer

GoHighLevel is not field service software, and pretending otherwise is the most expensive mistake in this build. Technician scheduling, job costing, refrigerant logs, timesheets and van stock usually stay in a dedicated platform.

HighLevel owns everything from first touch to accepted quote, plus everything after the job: reminders, reviews, reactivation, recurring billing. If you are weighing the two layers against each other, our comparison of HighLevel and simPRO on true cost lays out where each one earns its keep.

Also worth noting for your website copy: work on refrigeration and air conditioning equipment requires a Refrigerant Handling Licence from the Australian Refrigeration Council, and displaying your ARCtick licence is a genuine trust signal your unlicensed competitors cannot copy.

Common mistakes to avoid

• Building the surge-capture Workflows in November, when you have no time to test them and no patience for debugging
• Running reactivation campaigns to a cold list without checking consent, which puts you on the wrong side of the Spam Act
• Letting quote follow-up run manually — it is the first thing dropped the moment the diary fills
• Selling maintenance agreements by phone months after install instead of automatically at job completion
• Using contact creation date rather than an install date custom field to drive long-horizon reminders
• Trying to run technician scheduling and job costing inside HighLevel because you want one login

Frequently asked questions

Does GoHighLevel replace field service software for an HVAC business?

No. GoHighLevel is the sales and marketing layer — lead capture, quoting, follow-up, reminders, reviews and recurring billing. Technician dispatch, job costing, refrigerant logging and van stock usually stay in dedicated field service software, with the two connected by webhook or automation.

How much does GoHighLevel cost for an Australian air conditioning business?

HighLevel's published 2026 plan pricing is US$97 per month for Starter, US$297 for Unlimited and US$497 for Agency Pro. Most single-location HVAC operators only need Starter. Budget separately for LC Phone or Twilio usage, since SMS and call minutes are charged on consumption.

Will missed call text-back work on an Australian mobile or landline number?

Yes, provided the number is provisioned through LC Phone or a connected Twilio account so HighLevel can see the call status. You can either toggle the native feature on under Settings and Business Profile, or build a Workflow using the Missed Call trigger for more control. A number simply forwarded from an existing landline will not report call status back to the platform.

When should I run pre-season campaigns in Australia?

Market before the weather turns, not during it. September to October works for pre-summer cooling checks and April to May for pre-winter heating, though you should shift those windows for your climate zone. The Bureau of Meteorology publishes long-range seasonal outlooks that are useful for deciding when to pull a campaign forward.

Can GoHighLevel handle recurring maintenance agreement billing?

Yes, using recurring products with a subscription price, sold through a payment link or an accepted estimate. The purchase trigger can then apply a membership tag and start your service scheduling Workflow. Many Australian operators still reconcile in their accounting package, so check how the payment data flows into your books before going live.

Is it legal to text past customers a pre-summer offer?

The Spam Act 2003 allows consent to be inferred where there is an existing commercial relationship relevant to the message, but the ACMA's stated preference is express consent. Every message must identify you as the sender and include a working unsubscribe that requires no login or extra personal details. Capturing an explicit marketing opt-in at the quote stage is the safest approach.

How long does this HVAC build take in HighLevel?

A competent operator working steadily can get surge capture and quote follow-up live inside a week. The full build including maintenance agreements, seasonal campaigns and long-horizon reminders is realistically two to four weeks. Starting from a prebuilt trade snapshot cuts that considerably.
