Many Gymea homes were built in the 1950s and 60s and have been renovated since, and a fair few now have solar on the roof. We size systems to keep power bills sensible and make the most of the sun when you have it.

Air conditioning in Gymea usually comes with one question: how much will it cost to run? The answer depends on sizing, insulation, zoning and how you use it, and solar panels can cover a lot of daytime running. Alpha & Omega installs efficient Daikin inverter systems in Gymea homes and has worked across the Sutherland Shire since 1989.
Solar panels produce the most power in the middle of the day, which is exactly when a summer afternoon starts heating the house.
Running the air conditioning during daylight hours, and cooling the house a little earlier than you normally would, lets more of that power go into comfort instead of back to the grid for a small feed-in credit.
Most of these cost nothing, and a couple are worth doing when the system goes in.
The most efficient system is the one that matches how you actually use the house.
| How you live | What we would fit | Why it saves |
|---|---|---|
| Mostly in one or two rooms | Inverter split systems in those rooms | You only power the rooms you use Splits → |
| Whole family, whole house | Zoned ducted reverse cycle | Zones let you switch off empty parts of the house Ducted → |
| Renovated rear extension | A split or multi-split for the new rooms | No need to oversize the original system Multi-split → |

Efficient new systems, plus servicing that keeps older ones running well.
Plenty of Gymea renovations add a big open living area at the back. That room usually needs its own system.

Other signs to look out for:
It can. Solar panels produce most power in the middle of the day, so running the system then, especially to pre-cool the house, uses power you have generated instead of buying it from the grid.
Around 24 to 26 degrees in summer and 18 to 20 in winter suits most people. Every extra degree of cooling or heating adds to running costs.
Yes, generally. Inverters adjust their speed to match the load instead of switching fully on and off, which uses less power and keeps the temperature steadier.
It depends on how you use the house. Split systems are cheapest when you only use a couple of rooms. Zoned ducted is efficient for whole-house comfort as long as you switch off unused zones.
Not always. If you have added an extension, a separate split for the new area is often better than replacing or overloading the original system.
