Air Conditioning Installation in the Hills District
Summers in Sydney’s north-west regularly top 40°C, and winter nights in Dural, Glenorie and Galston get cold. FMZ Electrical supplies and installs split system and ducted air conditioning from trusted brands including Daikin, Mitsubishi Electric, Fujitsu and Panasonic. Because we’re licensed electricians, the dedicated circuit, isolator and switchboard work are all handled in-house. There’s no waiting on a second trade.
Ducted Air Conditioning for Larger Homes & Acreages
Many Hills District homes are large, single or double storey, with high ceilings, which makes ducted systems a popular choice. We size each system to your home’s heat load, design zones for living and sleeping areas, and install smart controllers so you can run the system from your phone.
Split System Installation
For bedrooms, granny flats, home offices and studios, a split system installation is fast and affordable, and most back-to-back installs are finished in half a day. Inverter models are also energy efficient. Compare star ratings on the Energy Rating website.

Frequently Asked Questions
How much does air conditioning installation cost in the Hills District?
A back-to-back split system typically costs $1,800 to $3,500 supplied and installed, depending on size (2.5kW to 8kW) and brand. Ducted air conditioning for a typical Hills District home usually ranges from $9,000 to $18,000, depending on the number of zones, roof access and system capacity. We give a fixed price after a free in-home assessment. These are typical Sydney industry figures only. Costs can vary depending on your property and requirements, and your exact price is confirmed in writing after a free inspection.
Should I choose ducted or split system air conditioning?
Split systems are the most affordable way to cool individual rooms and are quick to install. Ducted systems suit larger homes. They heat and cool the whole house through discreet ceiling vents, with zoning so you only run the rooms you use. We’ll recommend the right option based on your floor plan and budget.
Do I need a switchboard upgrade for a new air conditioner?
Larger split systems and ducted units need their own dedicated circuit and RCD protection. If your switchboard is old or full, we may recommend a switchboard upgrade. We’ll check this during your quote.
Do you repair and service existing air conditioners?
Yes. We service, repair and re-gas split and ducted systems from all major brands, including electrical faults, isolator replacements and units that won’t turn on, blow warm air or trip the power.
