Heating and cooling pricing in Pakenham — 2026 install + service guide
Heating and cooling in Pakenham is one of those areas where the price spread between operators is huge — and the cheap end almost always cuts corners on the refrigerant work (which has to be done by an ARCtick-registered tech) or skips the AS/NZS 5601 gas commissioning. This guide gives you the realistic 2026 numbers so you can spot a quote that's missing something.
Install pricing depends mostly on capacity, install difficulty, and whether ducting is involved. Service pricing is fairly tight. Call (03) 9003 0108 for an exact quote on either side.

What changes the price on your job
The ranges above are the starting point. These five factors are what move a quote up or down within (or sometimes outside) those bands.
- Capacity sizing — under-sized cuts your run-time, over-sized cuts your humidity control. We calculate to AS/NZS 4426 not just 'kW per square metre'.
- Pipe run length — every metre beyond the standard 3–5m back-to-back adds material + labour.
- Roof/wall access — second-storey, scaffold-required, asbestos-eave sites all add.
- Existing gas changeover — gas-cap-off + abandonment cert is $280–$450 we don't include unless quoted.
- Rebate eligibility — VEU (VIC) and federal Small-Scale Technology Certificates can net $1,500–$3,500 off a ducted reverse-cycle install. We process the paperwork.
Red flags — what to watch for in quotes
We see these patterns every week from operators we'd never recommend. If a quote you've received contains one of these, ask before signing.
- Installer not ARCtick-registered — illegal to handle refrigerant in AU. Check the registration number on the ARC database before signing.
- Quotes without specific model numbers — leaves them free to swap to a cheaper unit on the day.
- Refrigerant 'top-up' without leak detection — illegal under EPA, masks a leak that destroys the compressor by year 3.
- No drainage detail — condensate water has to go somewhere; cheap installs run it onto the eaves or the neighbour's fence.
- Cash discounts that come with no warranty paperwork — manufacturer warranty needs the install certificate, which needs an invoice.
How to get an accurate quote in 5 minutes
Have the following ready when you call (03) 9003 0108 (or jot it on the quote form) and we can give you a real number in one call, not five.
- The home's floor area and number of bedrooms (for sizing).
- Existing system age and type (for changeover or like-for-like).
- Whether the home is single or double storey.
- Eave/roof construction — tile vs Colorbond, asbestos or not.
- Existing gas service if a gas-to-electric changeover is on the cards.
