Ducted Air Conditioning Sydney – Expert Installation & Service by ACG Air Conditioning Guys
For over a decade, ACG Air Conditioning Guys has helped Sydney homes and businesses enjoy year-round comfort with ducted air conditioning that’s quiet, efficient and beautifully discreet. From new installations and replacements to responsive repairs and scheduled maintenance, our licensed, insured and ARCtick-certified team delivers reliable results across the metro.
Why Choose Ducted Air Conditioning in Sydney?
Sydney’s climate throws everything at you—humid summer heat, southerly changes, cool winter nights. While wall-mounted split systems are great for single rooms, ducted air conditioning shines when you want controlled, even temperatures throughout the whole property.
Whole-home comfort (without the clutter)
One central indoor unit distributes conditioned air through insulated ducts to subtle ceiling or floor vents. You get consistent temperatures with barely any visual footprint—ideal for modern, minimalist interiors and heritage homes alike.
- Beautifully discreet: no bulky wall units across multiple rooms
- Even temperatures from bedroom to living and kitchen
- Ultra-quiet indoors—noise stays at the outdoor unit
Zoning that fits your lifestyle
With smart zoning, you can heat or cool only the areas in use—bedrooms at night, living zones by day—reducing energy waste without sacrificing comfort. Many households also choose separate weekday/weekend schedules for maximum efficiency.
- Zone by floor, by room groups, or by activity
- Program schedules and temperature set-backs
- Optional Wi-Fi/app control for remote access
Mini case study: three splits → one ducted
A family in Strathfield replaced three aging splits with a single ducted system and zoning. Result: fewer hotspots, quieter nights, and an electricity bill reduction reported at roughly a quarter in summer (usage-dependent). The added bonus was cleaner walls and a neater interior aesthetic.
How Ducted Air Conditioning Works
Think of a ducted system as a central climate engine. It draws room air through a return grille, conditions it (cooling or heating), then pushes it back via ducts to ceiling or floor vents.
| Component | What it does | Notes |
|---|---|---|
| Outdoor unit (condenser) | Moves heat in/out using refrigerant and an inverter compressor | Modern inverter tech ramps power up/down to match demand—quiet and efficient |
| Indoor fan coil | Houses the evaporator coil and fan that circulates conditioned air | Usually installed in ceiling/roof space or underfloor |
| Insulated ducts | Carry conditioned air to each zone/room | Proper sizing and insulation prevent losses and noise |
| Supply registers | Ceiling/floor vents that deliver air | Discrete, low-profile designs suit any décor |
| Return air grille | Pulls room air back to the indoor unit | Often combined with a filter for better air quality |
| Controller & zoning | Sets temperature, schedules, and which zones are active | Wall keypad and/or smartphone app |
Key Benefits of Ducted AC with ACG
Year-round comfort
Reverse-cycle ducted systems deliver cooling in summer and heating in winter with the same equipment. No need for separate gas heating: one system, one controller, smooth comfort all year.
Energy efficiency by design
- Inverter compressors right-size power to actual demand
- Zoning lets you condition only occupied areas
- Programmable schedules avoid “set and forget” waste
- Proper duct design minimises pressure losses and noise
Aesthetics & value
Low-profile vents keep your walls free of big indoor heads—great for open-plan living and styled interiors. Many buyers see ducted AC as a premium feature that lifts resale appeal.

Ducted AC Installation in Sydney
Every home is different. We start with a careful site assessment and design a system that fits your structure, lifestyle and budget.
- Consultation & heat-load assessment – room sizes, insulation, glazing, orientation and usage patterns.
- System design – capacity, duct sizing, register placement, and a zoning plan (day/night/guest/home-office).
- Professional installation – safe electricals, neat penetrations, balanced airflow and sealed ductwork.
- Testing & handover – airflow balancing, commissioning, user training, and tidy clean-up.
Common Sydney property scenarios
- Terrace & heritage homes: low roof space? We plan compact routes or underfloor options.
- Double-storey: split day/night zones, risers positioned for minimal visual impact.

- Commercial: after-hours installs to minimise business disruption.
Compliance & safety
We operate under NSW licensing requirements and ARCtick regulations for refrigerants. You get documentation to support warranties and resale.

Routine maintenance preserves efficiency, cuts running costs and extends system life. It also prevents airflow issues that make systems noisy or uneven.

FAQs – Ducted Air Conditioning Sydney
How much does ducted air conditioning cost in Sydney?
Most standard homes fall between $8,000–$15,000 installed, depending on brand, duct length, zoning, and access. Complex or premium systems can be higher. We confirm pricing after a site visit so there are no surprises.
How long does installation take?
Single-storey homes are commonly completed in 1–2 days; double-storey/complex layouts 2–3 days. We handle permits/approvals where required and plan neat routes to protect your finishes.
Can you retrofit ducted into an existing home?
Usually yes. We map trusses/joists, choose compact indoor units if space is tight, and may use underfloor runs in some homes. For apartments, we coordinate with strata where necessary.
Is zoning worth it?
For most Sydney families: absolutely. You’ll condition only the rooms you’re using, which improves comfort and cuts waste. Popular layouts include “day” (living/kitchen) and “night” (bedrooms) zones.

We service and repair major brands including Daikin, Fujitsu, Mitsubishi, Actron Air, Panasonic, Samsung and LG. If parts are available, we can usually help.
How often should I service?
Annually for most homes; every 6 months for coastal, dusty or heavy-use homes and all commercial sites.
What’s the typical lifespan?
With regular maintenance, many ducted systems last 12–20 years. Filters and clean coils protect efficiency and extend life.
