A Darwin aircon works harder than most
In Darwin the aircon is not a summer extra. It runs most nights for most of the year, and through the build-up it barely gets a break. A unit that is too small for the room runs flat out and still leaves you sweating.
An install that looks fine on day one can let you down later. Condensate that drains onto a path turns into a slip hazard and a mould patch. An outdoor unit sat in the wrong spot cooks in the afternoon sun. And a new system on an old switchboard can trip the power the first hot night you lean on it.

What a Fosters split system installation includes
Sean or one of the team visits first, looks at the room and the switchboard, and gives you a price before any work is booked.
Sizing for long running hours
We size the unit for the room, the windows and the hours you will run it. A bedroom that only runs overnight needs something different to an open living area that faces the afternoon sun.
Indoor unit placement
We place the head where the air reaches the bed or the couch, not just where the wall is easiest. We also plan where the pipes and cable run so the finish is tidy.
Outdoor unit placement and brackets
We look for a spot with airflow and some shade, on a galvanised wall bracket or a ground mount. On raised houses we work out the pipe run between floors before we drill.
Securing the outdoor unit for cyclone season
We talk you through how the outdoor unit is fixed down, so you know what is holding it when the wet season storms come through.
Condensate drainage
Darwin humidity means a split system pulls a lot of water out of the air. We run the drain line to a sensible point, not onto a walkway or a neighbour's fence.
The circuit and the switchboard
Many new systems need their own circuit. Sean is an electrician, so we run it and check your switchboard can carry the load. If the board needs an upgrade, we tell you before we start. More on our electrical services.
Commissioning and clean-up
We test the system, show you the remote and the filters, and take the packaging away.
We lead with Daikin, and the Daikin Alira X is the split system we recommend. Mitsubishi Electric, Fujitsu and Panasonic are available on request. Live close to the coast? Ask us about condenser coatings for salt air when we quote.
Need more than one room on one outdoor unit? We install multi-split systems. Want the whole house cooled from one system? We install ducted air conditioning too, and we will tell you honestly whether ducted or splits suit your house better. We install ceiling cassettes as well, for open-plan rooms and offices.
Why book your install with Sean and the team
One team for the unit and the power
Plenty of aircon installs need a separate electrician for the circuit. With Fosters, the person fitting the aircon holds the electrical licence too. One booking, one invoice, and nobody waiting on another trade.
Options first, then a price
Helen asked for a quote and got a conversation first. In her words, Sean was "really prompt to come out and chat and options and quote for the work." You choose the unit knowing why.
We leave the site clean
We pack up the boxes, offcuts and dust before we leave. Helen again: "Left things cleaner than what they were!"

Frequently asked questions
How much does air conditioning installation cost in Darwin?
It depends on the unit size, the brand, the pipe run and whether your switchboard needs work. Fosters gives you a free in-home quote with a written price before anything is booked, so you know the full cost up front.
What size split system do I need for a Darwin bedroom or living room?
It depends on the room size, the windows, the sun it gets and how long you run it. Darwin units run long hours, so we size for that. Sean measures up at the quote and recommends a size with the reason behind it.
Do I need a separate electrician to install my air conditioner?
Not with Fosters. Sean holds an electrical licence as well as a refrigerant handling licence, so we install the unit and run the dedicated circuit in the same job. If your switchboard needs an upgrade, we tell you at the quote.
Which air conditioner brands does Fosters install?
We lead with Daikin, and the Daikin Alira X is the split system we recommend. Mitsubishi Electric, Fujitsu and Panasonic are available on request. We will tell you which models suit your room and budget, and why.
Do you install multi-split and ducted systems?
Yes. We install multi-split systems, where one outdoor unit runs two or more indoor heads, and ducted systems that cool the whole house from one unit. At the quote we tell you which suits your house and why.
How is the outdoor unit secured for cyclone season?
We mount outdoor units on galvanised wall brackets or ground mounts and fix them down. At the quote we talk you through how your unit will be secured and what to check before the wet season.
How long does a split system install take?
We install a single back-to-back split system in one day. Longer pipe runs, raised houses or a switchboard upgrade can add time, and ducted jobs take longer. We give you the timing with the quote.
