The six HVAC rules that will save you money

When it comes to heating or cooling your business, there are six basic rules to follow:

  • Get as much of your heating, cooling and ventilation as possible from natural sources.
  • Watch your thermostat. Having the wrong settings can make a really big difference to your energy bills.
  • Keep doors, windows and vents closed when your air-conditioning is on. Having them open can put more pressure on your HVAC system.
  • Ensure that your HVAC system is properly maintained. This maximises its longevity and efficiency. Your EcoSmart Electrician or HVAC technical service provider can advise you on the best strategy.
  • Take the ‘Goldilocks’ approach when buying HVAC equipment. You don’t want it too big or too small. You need a system that’s ‘just right’ for your operations.
  • Get the most from your HVAC system. When you’ve got the system that’s ‘just right’ for your business, make sure that you use it in the most efficient way possible. Don’t turn it on unless you really need to.


Gelato Blue, NSW

Gelato Blue saved $2,000 a year after taking part in a state government energy efficiency program which advised them to improve their refrigeration and air-conditioning systems.


Insulation covers were specially developed for the ducted air-conditioning so that less energy was needed for cooling and heating the store. “The results exceeded our expectations,” said owner Constantinos Platis. “We have saved approximately 13% on our energy bills from the previous year.”


Inspired by the savings from the initial changes, they also installed a roof air ventilator for a more energy efficient way of cooling.[1]


Use the economy cycle

When it’s cool outside, use the economy cycle on your air conditioner. This brings in cooler air from outside and circulates it in your building.

This air is not artificially cooled so it reduces your air-conditioning bills.


St Andrew’s Cathedral School, NSW

At one of their two buildings, St Andrew’s Cathedral School implemented an economy cycle on air conditioning units and switched them to ‘manual’ during school holidays, so they can be turned off when not in use.[2]
