Heating and cooling in NewcastleSticky at Nobbys, hotter and drier a few suburbs west.

Which jobs come up most in Newcastle?

Split systems are the everyday job, particularly in apartments and terraces where there's one living area and a couple of bedrooms to look after. In a unit block, the owners corporation gets a say first: The Good Guys, for one, says body corp approval is required before any work in a multi-storey apartment block. Our page on apartments and strata explains how that usually runs.

In the separate houses that make up most of the city, ducted air conditioning is the other big decision. If you're in the warmer western suburbs, it needs sizing for their hotter afternoons rather than the coastal average.

Then there are the westerly days. A system that copes with a typical January afternoon at Nobbys can fall behind when a westerly takes the temperature past 40, and ActronAir says air conditioners lose cooling capacity above 35 degrees anyway. Near the coast, servicing matters more than people think, because humid air and salt both work on a system between visits.

Reverse cycle, gas and the ESS

With Jemena gas in many streets, some Newcastle homes are choosing between gas heating and reverse cycle. The ACT Government says a gas system heats quickly but reverse cycle has much lower running costs. Our reverse cycle or gas guide goes through the trade-offs.

If you're adding or replacing an air conditioner, ask whether the installer offers the NSW Energy Savings Scheme discount. It comes off the quote through an Accredited Certificate Provider that works independently of the NSW Government, and the nomination form has to be signed before installation begins. A new gas space heater installed from 1 July 2026 can't get it at all.
