Running an Air Conditioning Business in Australia
October hits and the phone goes berserk. Every homeowner in Queensland wants a new split system before Christmas. You're flat out through summer. Then April arrives and the phone goes quiet. You spend winter wondering where the next job is coming from. Every AC operator knows this cycle. The ones who break it are the ones who used March — while clients still remember the summer heat — to lock in annual maintenance contracts for the next 12 months.
What an air conditioning business looks like
What AC operators deal with
Seasonal feast and famine — the business model problem
Split system installs carry thin margins in a competitive market. Suppliers compete hard. Customers price-shop online. The install margin alone won't build a sustainable business. The operators who run profitable AC businesses year-round have built a maintenance contract base that generates revenue every month, not just every October.
Annual service agreements — filter clean, coil inspection, refrigerant check, drain flush, electrical check — at $150–$250 per system per year convert install clients into recurring revenue. Offered at every install before you leave the property, a meaningful percentage will say yes on the day. The rest get a reminder email in March.
Install margin compression — the margin is in the add-ons
The market has raced to the bottom on basic split system install pricing. If you're competing purely on install price, you're working hard for thin returns. The margin is in the add-ons: smart thermostats, ducted zoning upgrades, air purifiers, multi-head systems, commercial replacements. Every install quote should include at least one upgrade option.
Ducted system replacements are where the significant residential money sits — $8,000–$20,000 for a full ducted replacement with zoning. Clients with older ducted systems who've been with you since the split system install 5 years ago are the best prospects for this conversation.
Warranty documentation — non-compliance voids it
Every major AC manufacturer requires installation to follow their specifications for warranty to be valid. This means: correct pipe sizing, correct electrical, correct drainage fall, correct clearances. After every install, complete and submit the manufacturer's warranty registration and retain a copy. Photo-document the install — indoor unit position, pipe run, outdoor unit, electrical connection. When a client calls 2 years later with a warranty issue, this documentation protects both of you.
Where AC businesses lose recurring revenue
| Stage | What You Need | What's Actually Happening |
|---|---|---|
| Quoting | Install price + upgrade options listed. Annual service agreement offered. Warranty registration included in scope. Maintenance contract pricing shown. | Lowest install price quoted to win the job. No add-ons. No service agreement conversation. One-off transaction. |
| Job Management | Install photos. Warranty registration completed. Service agreement signed. Next service booked in system before leaving. | Install done. Warranty registration not completed. No service agreement. Client lost until next breakdown. |
| Invoicing | Invoice on completion. Annual service agreement invoiced separately. Payment collected on site. | Invoice sent by email. Payment arrives 2 weeks later. No service agreement invoice. Revenue opportunity missed. |
| Payments | Card payment collected on site or Stripe link in invoice. Same-day payment standard for residential. | Bank transfer only. Client takes 10 days. Chasing payment eats admin time. |

At every install, offer an annual service agreement before you leave — filter clean, coil inspection, refrigerant pressure check, drain flush, and electrical check at $150–$250 per system. Ask directly: "Want me to book you in for next April?" Most clients say yes. Book it in your system on the spot.
March and April are the best time for service reminders — clients still remember the summer heat. Send annual service emails to your entire install client list. Offer pre-winter servicing for ducted systems. Operators who run this campaign consistently fill their June–August calendar with maintenance work.
Complete the manufacturer's warranty registration after every install and keep a copy. Photo-document the install — indoor unit, pipe run, outdoor unit, electrical. When a warranty issue arises 2 years later, this protects both you and the client. Non-compliant installation voids the warranty — follow the manufacturer's specifications every time.
