The warranty trap on commercial work

Residential warranties look generous at five to seven years. Commercial drops to two or three, often two. And here's the one that catches people. Seeley's seven-year warranty depends on buying through a participating Seeley dealer. Buy the same unit through a wholesaler and it's five.

Why does commercial work catch people out?

Because everybody quotes the residential number, and it's the commercial number that applies to the job. Price a light commercial job on the residential warranty and you're carrying the risk yourself for the years after handover.

Almost nobody knows this

Where you buy it can change the warranty

Seeley's seven-year warranty only applies if the unit comes through a participating Seeley dealer. Buy the identical unit through a wholesaler and it carries five.

That's two years of warranty won or lost by whoever rang the order in, and they usually had no idea it mattered. Check it before the next big order, not after the next failure.

Which brand has the most generous warranty?

Rinnai, on its refrigerated air conditioning and VRF (variable refrigerant flow) systems. Seven years parts and labour, residential and light commercial, from 1 April 2025. Labour's the bit that usually gets left out of a headline warranty, and it's the bit that costs you money when you're the one going back.

Rinnai also manufactures at Braeside in Victoria. That's handy when a customer asks about local support, but don't take it to mean their air conditioner was built there.

What actually voids a warranty?

The pattern's pretty consistent across manufacturers, even where the terms differ. Keep commissioning and evacuation records, do the pipework properly, install to the manual, and don't use stop-leak. With that evidence on file, most claims are straightforward.

Be careful repeating brand-specific voiding claims. They change without notice, and getting one wrong could cost a contractor a claim. If it matters on a job, get the current terms in writing from the manufacturer and date them.

About to commit to a big equipment order?

Warranty, trading terms, rebates and technical support are all negotiable, and the warranty's the one people forget to ask about.
