Split system installation in Hervey Bay
Split system installation in Hervey Bay is how most homes cool a living room or a bedroom that will not settle on a January afternoon. The system is two pieces: a head on the inside wall, and a compressor outside, joined by pipe, a drain, and a power supply. It is not a window box and it is not ducted air through the ceiling. It cools the space it blows into.
Summers here are long and humid. A unit that is too small runs and never catches up. A unit that is far too big for a closed bedroom can cool the air and leave it clammy. Sizing is part of the quote, not a guess from the box in a shop. Ask us and we’ll talk you through the room before anyone buys a unit.
The power supply to the outdoor unit is electrical work. Best in the Bay holds electrical contractor licence 1511769 for that part.
Split system or ducted?
A split system cools the room it blows into. It is usually the quicker install: one indoor head, one outdoor unit, and a pipe through the wall. Ducted air conditioning cools most of the house from one system, with outlets in the rooms you choose and a controller on the wall. If you want more than one or two rooms on the same system, read that page before you decide.
When a split system is the right job
People call when:
- One room is the problem: the living area in the late afternoon, or a bedroom that stays warm after dark.
- An old split system has failed and the pipe run and the power are already there. A replacement is not always a straight swap. The old location might be poor, and the board might still be undersized.
- A renovation has closed in a patio and the new room has no cooling.
- A window unit or a portable is noisy, wet, and not keeping up.
If every room is hot and you want them all handled together, say that at the start. A single split system will disappoint you. We would rather design two heads, or tell you this is the wrong product, than sell one and leave the back bedrooms untouched.
What we decide before the day
We stand in the room and outside the wall.
Inside, the head needs a solid fixing, a clear path for air, and a drain that falls all the way to outside. A drain that runs uphill, or that dumps into a garden bed against the house, is how ceilings get stained later. Humidity in Hervey Bay means those drains actually carry water. They are not optional.
Outside, the unit needs space in front of the coil, a bracket or a pad that will stay level, and a spot that is not boxed in by a fence. Salt air off the coast settles on coils and fins. Putting the unit in a sheltered place, and leaving it serviceable, matters more here than it does inland. We will not hide it where a technician cannot clean it.
The pipe run between the two should be as direct as the building allows. Long runs, many bends, or a path through a wardrobe are all visible in the quote.
Then the switchboard. A dedicated circuit is the normal way to supply the outdoor unit. If the board cannot take it, the electrical work includes that fix. See the switchboard upgrade page if the board is already full of fuses.
How installation goes
The indoor head is mounted and the hole through the wall is made for the pipes and the drain. The outdoor unit is fixed. Pipes are connected, pressure tested, and evacuated before refrigerant is dealt with the way the manufacturer requires. Power is connected and the unit is run. We check that it heats or cools, that the drain is moving water, and that the covers are back on.
The time on site is confirmed with you. A two-storey run, a tiled roof crossover, or a switchboard upgrade changes the day.
We install Daikin, Fujitsu and Mitsubishi, among others. Nothing on this page is a promise of a warranty length. Ask us when we quote and we’ll tell you what warranty applies to the unit.
You will be without power on that circuit, and possibly the whole house for a short time if the board is being worked on. We say so before we isolate.
What changes the price
No prices on this page. The quote follows:
- The capacity the room needs, and the model that matches it.
- Pipe length, wall type, and whether the outdoor unit is on a bracket high on the wall or on a slab.
- A new electrical circuit, and any switchboard work that circuit forces.
- Access: a clear side path versus scaffolding or a second storey.
- Drainage that cannot fall by gravity, so the water has to be pumped. Ask us on the day and we’ll talk you through how it gets outside.
- Replacement of an existing system versus a house that has never had one.
Why use one local team
The electrical supply and the board are our work under the contractor licence. Cooling load, pipe run, and drain are planned in the same visit so the unit is not powered from a board that cannot hold it. Cleaning later is the air conditioner cleaning page, once the unit has been through a humid summer and the filters and the coil need a proper look.
Call with the suburb and the room you want cooled. Photos of the wall, the outdoor side, and the switchboard make the first conversation useful. If you have already bought a unit, tell us the model before we book the day.
