Already have ducted gas heating and want cooling too? You have a few options — an add-on cooling coil, a full ducted refrigerated system, or split systems for key rooms. Here’s how each works and when it makes sense.

You can often add cooling to a ducted heating system — via an add-on cooling coil, a full ducted refrigerated system, or separate splits for key rooms. The best option depends on your existing ductwork, the heater’s age, and your budget.
Can I Add Cooling to Ducted Heating?
If you have ducted gas heating and want cooling too, you generally have options — and you may be able to use your existing ductwork. The three common routes are add-on refrigerated cooling (adding cooling to your existing ducted system), a full ducted refrigerated system, or separate split systems for key rooms. Which suits you depends on your existing ducts, the heater’s age and condition, and your budget (see the comparison above).
Add-On Refrigerated Cooling
Add-on cooling adds a refrigerated cooling component to your existing gas ducted heating, so the same ducts and vents deliver cooling in summer and heating in winter. Where your existing ductwork is suitable, it can be a cost-effective way to get whole-home ducted cooling without installing a whole new system. Suitability depends on the existing system and ducts, which we assess on site. It’s a popular choice for homes with sound heating ducts already in place.
A Full Ducted Refrigerated System
If your gas heater is old or due for replacement, a full ducted refrigerated (reverse-cycle) system can be the better move — it heats and cools electrically through ducted vents in one system, and modern units are very efficient. With electrification incentives and rising gas prices, replacing an old gas heater with ducted reverse cycle is increasingly attractive. We compare the running costs and fit for your home. See our ducted reverse cycle library.
Split Systems for Key Rooms
If you mainly want to cool a few rooms rather than the whole home, split systems in the living areas and bedrooms are a lower-upfront-cost option that doesn’t touch your ducted heating. They cool room by room efficiently, and you only run what you need. Many homes pair their ducted gas heating with splits for cooling the rooms that matter. See our split system library.
Choosing the Right Option
The best option depends on your existing ductwork, your heater’s age, how much of the home you want to cool, and your budget. Add-on cooling suits sound existing heating ducts; a full ducted reverse-cycle system suits a heater that’s due for replacement; splits suit cooling a few rooms affordably. We assess your home and recommend the option that fits, with a clear quote — rather than pushing one approach. Call 0431 918 137 or request an assessment.
Frequently Asked Questions
Can I add air conditioning to my existing ducted heating?
Often yes. A common option is add-on refrigerated cooling, where a cooling coil is added to work with your existing ducted heating system and ductwork, giving you cooling through the same vents. Whether it suits depends on your existing ducts, the heater and the layout. Alternatives are a full ducted refrigerated system or separate split systems. An assessment determines the best fit for your home.
What is add-on cooling for ducted heating?
Add-on cooling adds a refrigerated cooling component to an existing gas ducted heating system so the same ductwork and vents deliver cooling in summer as well as heating in winter. It can be a cost-effective way to get ducted cooling when you already have the heating ducts in place. Suitability depends on your existing system and ductwork, which we assess. It’s one of three common routes to adding cooling.
Is it better to add cooling or replace with ducted reverse cycle?
It depends on your heater’s age and your goals. If your gas heater is sound, add-on cooling lets you keep it and add cooling efficiently. If the heater is old or due for replacement, a full ducted reverse-cycle system (which heats and cools electrically in one) may make more sense — especially with electrification incentives. We compare the options for your situation. See our ducted reverse cycle library.
Can I just use split systems instead of ducted cooling?
Yes — split systems in key rooms are a common, lower-upfront-cost way to add cooling without ducted cooling. They’re ideal if you mainly want to cool a few rooms (living areas, bedrooms) rather than the whole home. The trade-off is room-by-room units rather than whole-home ducted cooling through your existing vents. For some homes, a mix works best. See our split system library.
How much does it cost to add cooling to ducted heating?
It’s quoted per job after an assessment, because it depends on which option suits your home (add-on cooling, full ducted refrigerated, or splits), your existing ductwork and system, and the capacity needed. Each option has a different cost profile. We assess your home and ducts and provide a clear quote for the option that fits. Call 0431 918 137 or request an assessment.
