Why booking now beats booking in December

Air conditioning is the most seasonal trade there is. Getting in early isn't a sales line. It changes what you pay, what you get and when you get it.

01 · The diary

You choose the install date

Through the cooler months there's room in the calendar. Once the first heatwave lands, the day fills with breakdown callouts and new installs get pushed back behind them.

02 · The stock

You get the system you actually want

The quiet, high-efficiency models in the popular sizes are the first to run short at the peak of the season. Order early and we fit what suits your place, not whatever is left in the warehouse.

03 · The install

Done properly, not in a rush

A roof cavity in a Hervey Bay January is a genuinely hard place to work. A cooler-month install is a cleaner install, and you're not sitting in the heat waiting for a slot.

Roughly what size will I need?

A starting point only. The real number comes from a heat-load calculation on site.

Floor area is only one input. Ceiling height, insulation, the amount and direction of glass, how exposed the room is and Hervey Bay's humidity all move the number, often up a size. We measure and calculate it properly before we quote, and the quote is a fixed price.

Not sure you even need a new one?

We'll tell you straight. If a service or a repair gets you another few summers, that's what we'll recommend, and we'll put the reasoning in writing either way.

Repair it, or replace it?

The honest answer usually shows itself in five minutes on site. Here's what we look for.

  • It's ten years or older. Efficiency drops away, and spare parts get harder to find every year.
  • It needs gas every season. Refrigerant doesn't get used up. If it's low again, there's a leak.
  • It runs all day and never gets there. Usually undersized for the room, or a compressor past its best.
  • It's noisy, rattling or icing up. Worth diagnosing before summer, not during it.
  • Your bills are climbing but nothing else changed. An ageing unit works harder to do less.

Specced for Hervey Bay, not for a catalogue

A system that works beautifully in a dry inland town can underperform badly here. Four things we account for locally.

  • Humidity, not just heat. An oversized unit cools fast, cuts out early and leaves the room cold and clammy. Sizing it properly is what gets the moisture out.
  • Salt air is real here. Close to the water we'll talk to you about corrosion-resistant condensers and put the outdoor unit somewhere it isn't taking the brunt of the salt spray.
  • West-facing glass. A wall of afternoon sun can add a whole capacity step to the calculation. We measure it rather than guess it.
  • Run it off your solar. Daytime cooling is the cheapest cooling there is. We install solar too, so we can look at the whole picture in one visit.

The polite agent was arrived as soon as possible for us to solve our a/c problem. I was flattered to see him voluntarily remove his boots before coming into the house. It means a lot and he certainly did solve our problem.

Very good service, only 3 days waiting time from booking and carrying out the job at a very competitive price. The staff was right on time, was very professional in cleaning six split system aircons, and left the inside and outside of the house in clean conditions. I would recommend this company for split system supply and install very much.

Prompt friendly service. After a bad experience with another local a/c company, we contacted O'Brien Electrical Hervey Bay for a repair job. The service tech turned up as scheduled and had the problem solved within 20 minutes (previous company hadn't fixed it in more than six months). Both the tech and admin staff were friendly and very helpful. Would definitely recommend.

Air conditioning questions, answered

How long does an air conditioner installation take?

A straightforward back-to-back split system is usually a same-day job. Most take three to five hours from arrival to handover. Multi-head systems and ducted installs take longer, generally one to three days depending on the run of the pipework and the roof access. We'll tell you which it is when we quote, not on the day.

What size air conditioner do I need?

The table above is a reasonable starting point, but floor area on its own gets it wrong often enough that we don't rely on it. Ceiling height, insulation, how much glass you have and which way it faces, how many people are usually in the room and Hervey Bay's humidity all change the answer.

Undersize it and it runs flat out and never quite gets there. Oversize it and it short-cycles, which cools the air without pulling the moisture out. That's the cold, clammy feeling. We do a proper heat-load calculation on site so you get the right one.

Should I repair my old unit or replace it?

It depends on age, what's failed and what a fix costs against a new system. As a rough rule: if it's under about eight years old and the fault is a single component, repairing is usually the better call. Past ten years, needing gas every season, or looking at a compressor replacement, and you're generally better off putting the money into a new unit that costs less to run.

We'll give you both numbers and a straight recommendation. If a repair is the smarter option we'll say so.

Will the salt air here wreck my outdoor unit?

It's a genuine consideration close to the water. Salt accelerates corrosion on the outdoor coil and casing, which shortens the life of the unit if it's ignored.

Two things help a lot: choosing a model with a corrosion-resistant coil treatment where the location warrants it, and siting the outdoor unit somewhere sheltered from the prevailing salt-laden wind. A periodic fresh-water rinse of the coil is worth doing too. We'll talk through what makes sense for your address when we're on site.

Are you licensed and insured?

Yes. Air conditioning work sits across two licences: electrical work and refrigerant handling. Both are legal requirements, not optional extras. Our team holds them, we carry full insurance, and every install is done to the manufacturer's specification so the equipment warranty stays valid.

Do you handle breakdowns and repairs, or only new installs?

Both. We service and repair systems we didn't install as well as ones we did: diagnostics, gas leaks, faulty boards, drainage issues, filter and coil cleans, and preventative servicing.

A pre-summer service is the cheapest insurance there is. Most of the breakdowns we attend in January were visible in September.

Can I run my air conditioning off solar?

Yes, and in this climate it's one of the better matches there is. Your cooling load peaks in the middle of the day, which is exactly when your panels are producing most. Running the house cool through the afternoon on your own generation costs far less than doing it on grid power at night.

We install solar and batteries as well as air conditioning, so we can look at both in the same visit rather than sending you to two different trades.

What does a new air conditioner cost?

It varies more than most people expect. Capacity, brand, how far the indoor and outdoor units are apart, whether there's an existing unit to remove and dispose of, and how hard the access is all move the price.

Which is why we quote on site rather than over the phone, and why the quote is a fixed price in writing. No allowances that grow on install day.

Do you do commercial work?

Yes. Shops, offices, clubs and light industrial, alongside the electrical side: switchboards, lighting, data, testing and tagging. If you need one contractor covering the air conditioning and the electrical, that's the easiest way to run it.

What areas do you cover?

All of Hervey Bay: Pialba, Point Vernon, Scarness, Torquay, Urangan, Urraween, Kawungan, Eli Waters, Dundowran, Wondunna, Nikenbah and Craignish. Plus Toogoom, Burrum Heads, River Heads, Booral, Susan River, Takura and down to Maryborough. If you're somewhere on the Fraser Coast that isn't listed, call us and we'll let you know.
