Signs Your Aircon Is Past Repair

Systems usually warn you clearly before they quit, and replacement beats another repair once those warnings start costing money. Watch for the signs below, then call us for an honest verdict on repair versus replacement:

Repair Bills Stacking

One compressor replacement can cost a third of a new system. If the last two summers each brought a service call, the maths has already tipped.

Parts Are Obsolete

Plenty of systems cooling these 1970s and 1980s homes were discontinued years ago. When a part has to be hunted second-hand, waiting for it is not a plan.

Running Costs Climbing

An ageing unit works harder for the same cool air, and you pay for that every day through summer. A new system with a strong star rating cuts the bill from week one.

It Never Kept Up

If the back rooms stay warm while the lounge freezes, the original system was undersized for the house. Replacement is the chance to size it properly at last.

Not sure whether it is a repair job after all? See our page on air conditioners not cooling, or read about air conditioning repairs if the system is still young.

What a Full Replacement Involves

A replacement is more than swapping a box on the wall. The job covers safe decommissioning of the old unit, correct sizing of the new one, a clean install and commissioning, and each stage matters:

Old System Out

We recover the refrigerant, disconnect and remove the old unit, and dispose of it properly. That work sits under our ARC licence L162586, the full refrigeration and air conditioning classification.

Sizing Comes First

Room-by-room load calculation comes before any recommendation. Brick-veneer walls, ceiling insulation and west-facing glass all change the answer.

New System In

Pipes, wiring and drainage go in clean, and the outdoor unit sits on a level base out of the afternoon sun where the layout allows. Everything is sealed and pressure tested before we close up.

Commission and Controls

We test pressures and temperatures under load, then walk you through the controller. The work carries the Lifetime Labour Warranty, so if a fault occurs due to workmanship, the team returns and fixes it at no cost.

Ducted or Split System for the New Unit

Houses here are overwhelmingly single-storey brick veneer, and that keeps the replacement choice straightforward. The main options sit below, and we will recommend the one that fits your home, your budget and how you live:

  • Split system air conditioning: one outdoor unit and one or two indoor heads, finished in a day. Suits households that only need certain rooms cooled.
  • Ducted air conditioning: whole-home comfort with zoning to shut off unused rooms, and the generous roof space in these homes makes the install clean.
  • Evaporative cooling: a cooling-only option that suits Adelaide's dry summer and runs cheaply with windows or vents open. It does not heat, so it is worth pairing with a separate heating system if you want both seasons covered.
  • Ducted gas heating: worth considering alongside ducted if the old gas heater is the same age as the cooling system.

We replace systems from Daikin, Mitsubishi Electric, Fujitsu and ActronAir, and we will match the brand to your budget rather than push the dearest one. We also cover Aberfoyle Park and the neighbouring suburbs.

What Drives the Cost of a New Cooling System

The price of a replacement turns on the system you choose and the house it goes into. Roof access, switchboard condition and the star rating you pick all move the number. The main drivers are below:

System type

Ducted costs more than a split, and zoning adds to it.

Access

Tight side setbacks or awkward roof space add hours to the job.

Switchboard

Some 1970s switchboards need an upgrade to carry a new unit safely.

Star rating

A better rating lifts the sticker price and drops the running cost for the life of the unit.

Ground and drainage

Sloping blocks need a level pad and graded condensate, which we price up front.

Finance

Larger jobs can be spread with Humm's interest-free finance.

Changeover Day

Why Book the Changeover Before Summer

The first run of 40-degree days fills every install calendar in Adelaide. Book in spring and you choose the date, the system and the price without racing the weather.

It also means the old unit dies on your schedule, not the heatwave's. Happy Valley Air Conditioning books changeovers right through the cool months.

Questions

Air Conditioning Replacement FAQs

How do I know it is time to replace rather than repair?

When repair bills stack up, parts are obsolete or the unit has never cooled the house properly, replacement usually wins, and we show you the numbers for both options before you decide.

Can you replace old systems in the 1970s brick-veneer homes?

Yes, and those homes often still run their first-generation unit, so we decommission it correctly, recover the refrigerant under our ARC licence and size the new system to the house.

How long does a replacement take?

Expect one day for a split system changeover and around two for ducted in these single-storey homes, with roof space, access and the switchboard deciding the final timing on the day.

Do you take the old system away?

Yes, removal and disposal are part of every replacement quote, and the refrigerant is recovered and handled correctly rather than vented, so you are not left with a dead unit on the nature strip.

Do you replace systems on sloping blocks near the reservoir catchment?

Yes, those sloping blocks toward the reservoir catchment need the outdoor unit on a properly level pad with condensate graded downhill, and we handle that as standard on every changeover.
