HVAC
A 17-technician HVAC company based in Christchurch, serving the wider Christchurch area and focused on heat pump installation and ducted heat pumps. Before working with us, 71% of enquiries came through Builderscrack and similar paid platforms, where the same lead often went to three or four competitors. The goal was more exclusive enquiries, a lower cost per booked job and a pipeline the owner controls.

The challenge
Where the business was stuck
- Demand spikes in the first heatwave or cold snap, then drops, and most marketing is switched on too late to catch the peak.
- Replacement and new-install jobs are worth many times a repair call, but most ad budgets are spent on low-value service searches.
- Maintenance agreements are the most profitable revenue in the trade, yet few HVAC websites actively sell them.
- Peak season (heating demand peaks from april to august; cooling demand rises in summer) was not being planned for, so budget ran out when demand was highest.
The approach
Three services, one goal
We focused on CRM Follow-up & Remarketing, Prospect Outreach (LinkedIn Sales Navigator) and Website Optimisation (UX/UI & CRO), the three channels with the best cost per booked job for HVAC businesses in Christchurch. Every call, form and chat was tracked to a booked outcome from week one, so every decision was based on revenue, not clicks.
What we did
The technical work behind the numbers, service by service.
Service 1
CRM Follow-up & Remarketing
- Connected every form, call and chat to a CRM pipeline with automatic SMS replies inside 45 seconds.
- Built a 6-step quote follow-up sequence by SMS and email for quotes that had not been accepted.
- Launched remarketing audiences on Google and Meta for site visitors and quote recipients, with job-specific ads and reviews.
- Added missed-call text back and reactivated 900 past customers with a service reminder campaign.
Service 2
Prospect Outreach (LinkedIn Sales Navigator)
- Defined the ideal customer profile and built 886 target accounts in LinkedIn Sales Navigator: facility managers, office and retail property managers, and builders.
- Saved lead searches with alerts for job changes, new projects and company growth, so outreach starts with a real reason to talk.
- Ran a 6-step manual sequence from the owner's profile: personalised connection note, value message, case study and a meeting request, within LinkedIn's weekly limits.
- Logged every conversation in the CRM and handed warm replies to the owner with account notes before each call.
Service 3
Website Optimisation (UX/UI & CRO)
- Ran a UX audit using heatmaps and 1,900 session recordings to find where mobile visitors dropped off.
- Rebuilt 9 landing pages with one offer, one call to action and proof (reviews, licences, guarantees) above the fold.
- Cut the enquiry form from 12 fields to 4, added a sticky click-to-call bar and a multi-step quote form on mobile.
- Ran 5 A/B tests on headlines, form placement and offers; the winning variants now carry all traffic.
