Air Conditioning
An 8-technician AC company based in Singapore's Central Region, serving the wider Central Region area and focused on aircon general servicing, plus chemical wash and chemical overhaul. Before working with us, 64% of enquiries came through Qanvast and similar paid platforms, where the same lead often went to three or four competitors. The goal was more exclusive calls and WhatsApp enquiries, a lower cost per booked job and a pipeline the owner controls.

The challenge
Where the business was stuck
- AC demand is intense in peak heat, and the fastest responder wins most breakdown jobs.
- Maintenance and servicing contracts offer stable revenue, but are hard to sell without a clear offer.
- Villa, apartment and commercial clients need completely different messaging.
- Peak season (demand is steady, with peaks in the hottest months (april to june)) was not being planned for, so budget ran out when demand was highest.
The approach
Two services, one goal
We focused on CRM Follow-up & Remarketing and AEO (Answer Engine Optimisation), the two channels with the best cost per booked job for air-conditioning businesses in Singapore's Central Region. 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 WhatsApp replies inside 45 seconds.
- Built a 4-step quote follow-up sequence by WhatsApp 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 2,300 past customers with a service reminder campaign.
Service 2
AEO (Answer Engine Optimisation)
- Rewrote 12 service pages so each opens with a direct 40 to 60 word answer to the question buyers actually search.
- Added FAQPage, HowTo and Service schema and question-led headings to target featured snippets and People Also Ask.
- Built a price and timeline guide for aircon general servicing with tables that answer engines can lift straight into results.
- Optimised for voice and conversational queries such as "how much does aircon general servicing cost near me".
