Check with your accredited installer when the maintenance is undertaken if consumption has changed significantly from purchasing new appliances.
Generally, any appliance that cools or heats will need more power than other appliances.
As a rule you should revisit your whole system periodically and replace or upgrade components as required. Your Accredited Installer should be the first point of contact for this.
