How Much Does Ducted Heating Unit Replacement Cost?

The answer to a question about how much something costs is almost always that ‘it depends’. In the case of ducted heating unit replacement, costs depend on several factors.

New or Existing

If you have an old system in place, the cost of a ducted gas heater replacement system will be considerably less than starting anew. You will have ducting, vents and controls so it may only be necessary to replace the heating unit. However, we’ll check all components and replace any that are outdated or inefficient, so you end up with a perfectly functioning system. We’ll also clean out ducts that need it so the system is completely hygienic.

Size of the Property

This is the major factor when installing a new system because it affects virtually every component, particularly the heating unit which has to be sufficiently powerful to heat the whole property. To assess this, take into account not only the number of rooms but also the size of each one.

Measure the total floor area to be heated and allow for unusually high ceilings that increase the volume. Take into account the area of windows and whether these are double-glazed since these can cause significant heat loss. As a rough guide, a 14kW system will be capable of heating an area of about 130 square meters of average height while 35kW is needed for 325 square meters.

The number of rooms and layout of the property will determine the length of ducting needed and the positioning of vents, which affect the overall cost. More than one story will necessitate vertical ducting, which is more expensive than being all on one level.

    System Quality and Features

    A top-quality system will cost more to buy but will be cheaper to run because it will be more efficient than an inferior, cheap system. It will also be more robust and so will last longer with lower repair costs. Better quality systems tend to have a higher star rating, which indicates increased energy efficiency and lower emissions. A reverse cycle system will cost more but will provide cooling as well as heating and so give year-round comfort.

    Natural gas is plentiful in Australia and so a ducted heat system will be cheaper to run than an electric one. The controller you install will affect the initial cost since some models have a wireless operation, multiple zoning, and variable fan speeds. However, these give greater control of the system and so significantly reduce operating costs.

    The cost of a system can be affected by where you are since it is generally lower where supply and demand are high. Luckily, this means that Melbourne residents pay much less than people living in Tasmania, for example, while natural gas rebates may be available.
