Brisbane changeover pricing (2026)
| Capacity | Fully installed (from, inc GST) | Includes |
|---|---|---|
| 2.5kW like-for-like | From $1,800 | New unit, install, old unit removal |
| 3.5kW like-for-like | From $2,000 | As above |
| 5.0kW like-for-like | From $2,200 | As above |
| 7.0kW like-for-like | From $2,600 | As above |
| Upsize (e.g. 2.5 → 5kW) | Quote on site | Larger pipe/electrical may be needed |
Like-for-like means same capacity, same bracket position, same electrical. Final price depends on whether existing pipework can be reused and on brand choice.
Can the existing pipework be reused?
Often yes — saves $200–$400. Conditions:
- Pipe size matches new unit. Most split systems 2.5–7kW use the same pipe sizes (1/4″ + 3/8″ or 1/4″ + 1/2″). Check at quote.
- Pipe was R410A or R32 rated. Pre-2003 R22 pipework usually unsuitable for newer refrigerants — replace.
- No kinks, corrosion or damage. Visual inspection at quote.
- Insulation intact. Damaged insulation reduces efficiency.
- System is being properly flushed before new charge to remove old oil residue.

When changeover beats repair
If your existing unit is 10+ years old AND has had a previous major fault, changeover usually beats another expensive repair. The math:
- 10-yr-old PCB replacement: $450 — gets you maybe 2 more years before the next failure
- 10-yr-old compressor replacement: $1,200 — on a unit that’s near end-of-life anyway
- New 2.5kW changeover: $1,800 — new 5-year warranty, modern efficiency, fresh start

Can you reuse the existing pipework?
Often yes — saves $200–$400. Conditions: pipe size matches, R410A/R32-rated (not R22), no damage, insulation intact, properly flushed before new charge.
How long does a changeover take?
4–6 hours for a back-to-back like-for-like. Longer if pipework needs replacing or upsizing.

Should I upsize during a changeover?
If the existing unit struggled in peak summer — yes, upsize by one capacity step (e.g. 2.5kW → 3.5kW). Brisbane climate has warmed over the last decade; what was adequate in 2013 may struggle in 2026.
