That was the case for a homeowner in Toorak Gardens, whose Daikin ducted air conditioning system had originally been installed by Morphett Air approximately 20 years ago.

When the ageing system stopped working, the homeowner got back in touch with us to find a solution.

The Problem

The homeowner noticed their Daikin ducted air conditioner would no longer start.

The light on the control panel was still illuminated, but the system itself wasn’t operating. A hard reset was attempted, but unfortunately this didn’t rectify the issue.

With the existing Daikin having already provided around two decades of service, the decision was made to replace the ageing system with a new ducted reverse cycle air conditioner.

Back to a Home We Know

There was a nice bit of history behind this particular job — Morphett Air had installed the original Daikin system around 20 years earlier.

Now, two decades later, we were back at the same Toorak Gardens home to replace it with another Daikin ducted system.

Getting approximately 20 years from the previous system is a great run, and this time the homeowner once again chose Daikin for their new air conditioning.

The New Daikin Ducted System

Morphett Air replaced the old system with a new Daikin FDYAN160A-C2V ducted reverse cycle air conditioning system.

The upgrade also included:

• A new Daikin controller
• A replacement zone motor
• Supply and installation of a remote temperature sensor in Bedroom 1
• Installation and commissioning of the new ducted system
• Testing of the system, controls and zoning to ensure everything was operating correctly

With the installation complete, the home once again had reliable ducted heating and cooling.

Updating the Controls and Zoning

Replacing an older ducted air conditioner can involve more than simply swapping the indoor and outdoor units.

As part of this installation, the home’s air conditioning controller and required zone motor were replaced to work with the new setup.

A remote temperature sensor was also installed in Bedroom 1, allowing the system to monitor the temperature from within the room as part of its operation.

Taking care of these components as part of the replacement helped ensure the new system was properly set up for the home.

Before and After

Before:
The approximately 20-year-old Daikin ducted air conditioner would no longer start. Although the control panel remained illuminated, the system itself wasn’t operating, and a hard reset didn’t resolve the problem.

After:
The ageing system was replaced with a new Daikin FDYAN160A-C2V ducted reverse cycle system, along with an updated controller, replacement zone motor and a new remote temperature sensor in Bedroom 1.

The result is a modern replacement ready to provide the Toorak Gardens home with heating and cooling for the years ahead.

When Is It Time to Replace an Older Ducted Air Conditioner?

A fault doesn’t automatically mean an air conditioner needs to be replaced. Depending on the problem, the age and condition of the equipment and the availability of parts, repairing an existing system can sometimes be the appropriate solution.

However, when a ducted air conditioner is approaching 20 years old and develops a significant problem, it’s worth considering whether investing in a new system makes more sense for the long term.

For this Toorak Gardens homeowner, the old Daikin had already delivered around two decades of service. And when the time finally came for a new one, Morphett Air was there again — around 20 years after installing the original.

When it’s too hot or cold to bare, reach for the Morphett Air

That was the case for Sam in Kidman Park, whose LG ducted air conditioning system was having trouble keeping the home comfortable.

The Problem

Sam contacted Morphett Air after experiencing problems with his LG ducted air conditioning system.

Our technician carried out diagnostic testing and found the lower condenser fan motor was faulty.

During testing, the outputs from the PCB were found to be correct, helping rule out the PCB as the cause of the problem. The fan motor could also still be spun by hand; however, it failed resistance testing, confirming a fault with the motor itself.

Rather than simply replacing parts based on symptoms, testing allowed our technician to identify where the fault was occurring and determine what was required to repair the system.

The Repair

Once the problem had been diagnosed, the necessary replacement parts were organised to get Sam’s LG ducted system operating correctly again.

The repair included:

● Replacement of the lower condenser fan motor

● Replacement of the fan motor harness

● Replacement of the fan blade

● Replacement of the disposable air filter

With the faulty components replaced, the system could be returned to operation and provide heating to the home once again.

Before and After

Before:
The LG ducted system had a faulty lower condenser fan motor. Although the PCB outputs tested correctly and the fan could physically spin by hand, the motor failed electrical resistance testing.

After:
A new lower fan motor, harness and fan blade were installed, along with a new disposable filter, getting the system back up and running.

Happy days — Sam’s all warm again!

Repair or Replace? A Proper Diagnosis Matters

An air conditioner fault doesn’t automatically mean you need a completely new system.

Depending on the system’s age, condition, availability of replacement parts and the nature of the fault, repairing an existing ducted air conditioner can still be a practical option.

That’s why proper diagnosis is important. By testing the system and identifying the failed component, we can give our customers the information they need to make an informed decision about whether to repair or replace their air conditioner.

If your ducted air conditioner isn’t heating, cooling or operating as it normally should, the Morphett Air team can diagnose the problem and recommend the appropriate next step.

When it’s too hot or cold to bare, reach for the Morphett Air

Recently, Morphett Air assisted a homeowner in Seacombe Gardens whose ageing Fujitsu ducted air conditioning system had suffered multiple component failures. After discussing the available options, the customer chose to replace the system with a brand-new Daikin FDYAN160A-C2V ducted reverse cycle air conditioner, along with a new replacement zone motor, providing reliable heating and cooling for years to come.

The Problem

The homeowner contacted Morphett Air after their ducted air conditioning system stopped operating correctly.

During our diagnostic inspection, our technician found the system displaying an E01 error code, indicating a fault with the system’s printed circuit board (PCB).

Further testing revealed the problem was more extensive than initially expected.

Our inspection identified:

• A faulty outdoor PCB.
• Faulty outdoor fan motor.
• Multiple major component failures.
• A faulty zone motor affecting the ducted zoning system.

With several key components requiring replacement, the customer was presented with two options:

• Repair the existing Fujitsu system by replacing the failed components.
• Replace the system entirely with a modern, energy-efficient ducted air conditioning system.

After discussing the costs, reliability and long-term benefits of each option, the homeowner decided that replacing the system offered the best value.

Our Solution

To provide reliable year-round comfort, Morphett Air supplied and installed a:

Daikin FDYAN160A-C2V 16kW Ducted Reverse Cycle Air Conditioning System

The installation also included:

• Safe removal and disposal of the original Fujitsu ducted air conditioning system.
• Installation of the new Daikin indoor and outdoor units.
• Replacement of the faulty zone motor to restore proper zoning operation.
• Connection to the home’s existing ductwork and electrical services where suitable.
• System commissioning and performance testing.
• Programming and demonstration of the controller and zoning functions.
• Complete clean-up of the work area, leaving the property neat and tidy.

Why Replace Instead of Repair?

While repairs can often be worthwhile, there comes a point where replacing an ageing system becomes the more economical option.

In this case, the existing Fujitsu system required replacement of multiple expensive components, including:

• Outdoor PCB.
• Outdoor fan motor.
• Zone motor.

Rather than investing in major repairs on an older system, the homeowner chose to upgrade to a brand-new Daikin system, benefiting from improved reliability, modern technology and the reassurance of a manufacturer’s warranty.

The Result

The customer now enjoys:

• Reliable heating and cooling throughout the home.
• Improved energy efficiency.
• Quiet operation.
• Restored zoning functionality with a new zone motor.
• Greater peace of mind knowing the system is backed by a new manufacturer’s warranty.

Replacing the ageing Fujitsu system has provided a long-term solution that’s ready for many years of dependable performance.

Recently, Morphett Air helped a homeowner in Fulham Gardens upgrade from a 20-year-old Carrier ducted air conditioning system to a brand-new Panasonic S-160PE4R/U-160PZH3R8 18kW ducted reverse cycle air conditioning system, providing dependable heating and cooling for many years to come.

The Problem

The homeowner contacted Morphett Air after their ageing Carrier ducted air conditioner stopped performing.

During our diagnostic inspection, our technicians found that while the outdoor unit was still running, there was no airflow coming from the ceiling outlets.

Further investigation revealed the indoor fan motor had seized, preventing conditioned air from circulating throughout the home.

To make matters worse, our technicians detected a strong burning smell coming from the indoor unit. Due to the potential fire risk, the system was switched off immediately, and the homeowner was advised not to continue using it until it had been repaired or replaced.

With the system now around 20 years old, major component failure, safety concerns and the likelihood of further repairs made replacing the entire system the most practical long-term solution.

The Solution

After assessing the home’s heating and cooling requirements, Morphett Air recommended installing a:

• Greater peace of mind knowing the previous safety concerns have been eliminated.

Rather than continuing to invest in an ageing system with major component failures, the homeowner now has an air conditioning solution designed to provide dependable comfort for many years to come.

When Should You Replace an Older Air Conditioner?

While many air conditioning systems can last 15 to 20 years with proper maintenance, there comes a point where replacement becomes more economical than ongoing repairs.

Some common signs it may be time to upgrade include:

• Your system is 15–20 years old or older.
• Frequent breakdowns or expensive repairs.
• Little or no airflow from the outlets.
• Burning smells or unusual noises.
• Rising electricity bills.
• Difficulty sourcing replacement parts.
• Poor heating or cooling performance.

If your technician identifies multiple major faults, replacing the system can often provide better long-term value than repairing an ageing unit.

Consistent temperatures throughout the home.

Modern controls and improved overall comfort.

Energy efficient

With one reliable system providing year-round climate control, the homeowner can enjoy greater convenience and peace of mind for many years to come.

The good news is that staying warm doesn’t always mean spending more. A few simple changes to how you use your reverse cycle air conditioner can improve efficiency and help keep your running costs under control.

Here are our top tips for reducing your heating bill this winter.

1. Set the Right Temperature

One of the easiest ways to reduce your heating costs is by avoiding unnecessarily high temperature settings.

For most homes, a temperature between 20°C and 22°C provides a comfortable balance between warmth and energy efficiency.

If you normally heat your home to 23°C or 24°C, consider lowering the temperature slightly. Even reducing the thermostat by one or two degrees can help reduce energy consumption while still keeping your home comfortable.

2. Don’t Always Turn Your Heater Off Completely

Many people assume that switching their heater off every time they leave the house is the cheapest option—but that’s not always the case.

If you’re only going to be away for a few hours and normally heat your home to around 23–24°C, consider lowering the thermostat to 18–19°C instead.

Your air conditioner won’t necessarily run continuously. It will only operate when needed to maintain that lower temperature, preventing your home from becoming excessively cold.

When you return home, the system has less work to do to bring the house back to your preferred temperature, which can reduce the workload on the compressor and improve comfort more quickly.

3. Use Wi-Fi Control If Your System Has It

Many modern air conditioners can be controlled remotely using a smartphone.

If your system has Wi-Fi capability, you can switch your heater on before arriving home instead of heating the house all day.

This allows you to enjoy a warm home when you walk through the door without running your heating unnecessarily for hours.

If your current system doesn’t have Wi-Fi, ask your installer whether it’s available for your model.

4. Clean Your Filters Regularly

Dirty filters restrict airflow, making your air conditioner work harder to heat your home.

We recommend checking and cleaning your filters regularly during winter, especially if your heater is used every day.

Good airflow helps your system operate more efficiently and can reduce running costs.

5. Close Doors to Unused Rooms

Why heat rooms you’re not using?

Keeping doors closed to spare bedrooms or other unused areas helps concentrate warm air where it’s needed most.

If you have a ducted system with zoning, turning off unused zones can further improve efficiency.

6. Close Curtains and Blinds at Night

Windows are one of the biggest sources of heat loss in winter.

Closing curtains or blinds after sunset helps keep warm air inside your home, reducing the amount of work your heater has to do.

Heavy curtains with pelmets can improve insulation even further.

7. Seal Draughts

Small gaps around doors, windows and older homes can allow warm air to escape and cold air to enter.

Simple draught seals or weather strips are an inexpensive way to improve comfort and reduce heat loss.

The less heat your home loses, the less often your heater needs to run.

8. Make Sure Your Home Is Properly Insulated

Even the most efficient air conditioner can’t perform at its best if your home is losing heat.

Ceiling insulation, wall insulation and double glazing can all make a significant difference to your home’s ability to retain warmth.

Improving insulation is often one of the best long-term investments for reducing heating costs.

9. Service Your Air Conditioner

A well-maintained system operates more efficiently.

Over time, dust and dirt can reduce airflow and place additional strain on your air conditioner.

Regular servicing helps identify potential issues before they become expensive repairs and ensures your system continues operating as efficiently as possible.

If your indoor unit has significant dirt build-up, an Eco Clean can remove contaminants from inside the unit, helping restore airflow and improve performance.

10. Make Sure Your System Is the Right Size

If your air conditioner is undersized for your home, it may need to run for long periods without ever reaching the desired temperature.

On the other hand, an oversized system may cycle on and off more frequently than necessary.

Having your system professionally assessed ensures it’s appropriately sized for your home’s layout and heating requirements.

Small Changes Can Make a Big Difference

Reducing your heating bill isn’t usually about making one major change.

It’s often the combination of:

• Setting a sensible temperature.
• Keeping filters clean.
• Closing unused rooms.
• Improving insulation.
• Using zoning effectively.
• Maintaining your air conditioner.

Together, these small improvements can make your home more comfortable while helping reduce your winter electricity costs.

“Should I leave my heater running all day, or turn it off when I leave the house?”

The answer isn’t always straightforward. It depends on your home’s insulation, your preferred indoor temperature, how long you’ll be away, and whether your system has smart features like Wi-Fi control.

Let’s look at the options.

If You Normally Heat Your Home to 23–24°C

If you like your home quite warm during winter, turning your air conditioner off completely before leaving for work may not always be the most practical option.

When you return home to a cold house, your air conditioner has to work much harder to bring the indoor temperature back up to your preferred setting.

Instead, many homeowners choose to lower the set temperature rather than switching the system off completely.

For example, if you normally heat your home to 23°C or 24°C, consider reducing the temperature to around 18°C or 19°C while you’re away.

At these lower temperatures, your air conditioner won’t necessarily run continuously. It will only operate when needed to maintain the reduced temperature, helping prevent the home from becoming excessively cold.

When you return home and increase the temperature back to your preferred setting, the system has a much smaller temperature difference to overcome, reducing the workload on the compressor and allowing the home to become comfortable more quickly.

If You’ll Be Away for an Extended Period

If you’ll be away for most of the day or overnight, turning the heater off completely may still be the better option.

Heating an empty home for long periods isn’t always necessary, particularly if nobody will benefit from the extra comfort.

Every home is different, so the best approach often depends on how well your home retains heat and how long you’ll be away.

Wi-Fi Makes It Even Easier

Many modern reverse cycle air conditioners are Wi-Fi compatible or can be upgraded with optional Wi-Fi control.

This allows you to turn your system on remotely using your smartphone before you arrive home.

Instead of heating the house all day, you can simply switch the system on an hour or two before you leave work so your home is already warm when you walk through the door.

This can provide a great balance between comfort and energy efficiency.

Good Insulation Makes a Difference

Homes with quality insulation, double glazing and good draught sealing retain heat much better than older homes.

If your home loses heat quickly, your heater may need to run more frequently regardless of whether you leave it on or switch it off.

Improving insulation can often have a bigger impact on comfort and running costs than changing how you operate your air conditioner.

Keep Your Air Conditioner Maintained

A well-maintained reverse cycle air conditioner will always perform more efficiently.

Dirty filters, blocked coils and restricted airflow can make the system work harder than necessary.

Regular servicing and an Eco Clean help keep your system operating efficiently, ensuring you get the best possible heating performance throughout winter.

So, Should You Leave Your Heater On All Day?

There isn’t a single answer that suits every home.

If you’re only away for part of the day and normally enjoy a warmer indoor temperature, lowering the thermostat to around 18–19°C instead of turning the system off completely can help maintain a more stable indoor temperature. Your heater will only run when required, and it won’t have to work as hard to warm the home when you return.

If you’ll be away for much longer, switching the system off or using Wi-Fi to turn it back on before you get home may be the more practical option.

The right approach depends on your home, your heating preferences and your lifestyle.

I think this version is more balanced. It avoids making blanket statements like “always turn it off,” acknowledges how inverter reverse-cycle systems behave, and introduces Wi-Fi control as a practical solution without making it sound like a sales pitch. It also aligns well with the kind of advice an experienced HVAC technician would give a customer.

Whether it’s a bedroom at the end of the hallway, a home office or a living area with large windows, uneven temperatures are one of the most common heating concerns we hear from homeowners during winter.

The good news is that there are several possible causes, and many of them can be identified and resolved with the right advice or a professional inspection.

Let’s take a look at some of the most common reasons why one room may be colder than the others.

1. The Room Is Further Away From the Indoor Unit

If you’ve only recently switched your heating on, it’s completely normal for rooms closest to the indoor unit or ducted outlets to warm up first.

Rooms located further away can simply take longer to reach the desired temperature, particularly in larger homes.

If you’ve just turned your system on, giving it a little more time may solve the issue.

2. Your Zoning Settings

If you have a ducted air conditioning system with zoning, start by checking that the room is included in an active zone.

Sometimes a zone may have been accidentally turned off through the wall controller or smartphone app, preventing warm air from reaching that area.

It’s also worth checking that the ceiling outlet or wall-mounted unit isn’t blocked by furniture or curtains.

3. A Faulty Zone Motor

If your system uses motorised zoning, the issue could be a faulty zone motor.

Zone motors control the dampers inside your ductwork, directing airflow to different parts of the home. If one of these motors fails or becomes stuck, the damper may remain closed, preventing warm air from reaching that room.

Some signs of a faulty zone motor include:

• One room receiving little or no airflow.
• Other zones heating normally.
• A room remaining cold even when the zone is switched on.

A qualified technician can test the zoning system and determine whether a zone motor needs repair or replacement.

4. Your System May Need Air Balancing

Not every room requires the same amount of airflow.

Air balancing is the process of adjusting airflow throughout your ducted system so each room receives the appropriate amount of conditioned air.

If a system hasn’t been balanced correctly, you may notice:

• Bedrooms staying colder than the living area.
• One room receiving significantly stronger airflow than another.
• Some rooms reaching temperature quickly while others struggle.

In many cases, a professional air balancing adjustment can make a noticeable difference to the comfort of your home.

5. Closed or Blocked Vents

Warm air needs to circulate freely.

A partially closed ceiling vent, furniture placed beneath an outlet or curtains covering a wall-mounted split system can all restrict airflow.

Check that:

• Ceiling outlets are fully open.
• Furniture isn’t blocking vents.
• Curtains or blinds aren’t preventing airflow.
• Nothing is restricting return air grilles.

6. Dirty Filters Restrict Airflow

Dirty air filters reduce the amount of warm air your system can circulate.

As airflow decreases, the rooms furthest from the indoor unit are often the first to feel colder.

Regularly cleaning your filters helps maintain airflow, improve efficiency and keep your home comfortable.

7. Damaged or Disconnected Ductwork

If you have ducted air conditioning, damaged ductwork could be allowing warm air to escape into the roof space instead of reaching your room.

Over time, ducting can:

• Deteriorate with age.
• Become crushed.
• Tear.
• Come loose.
• Be damaged by pests or trades working in the roof space.

Signs of ductwork problems include:

• Weak airflow from one outlet.
• One room consistently colder than the rest.
• Longer heating times.
• Higher energy bills.

A professional inspection can quickly identify whether your ductwork requires repair.

8. Your Home’s Layout

Some rooms naturally lose heat faster than others.

This is particularly true for rooms with:

• Large windows.
• External walls.
• High ceilings.
• Poor insulation.
• Tiled or concrete floors.

Bedrooms on the southern side of the home often feel cooler during winter because they receive less direct sunlight.

9. Open Doors Can Reduce Heating Efficiency

Leaving doors open allows warm air to spread throughout the home, meaning less heat is directed into the room you’re trying to warm.

If your ducted system has zoning, keeping doors closed to unused rooms can help improve comfort and efficiency.

10. Your Air Conditioner May Be Undersized

Sometimes the issue isn’t a fault at all.

Your air conditioner may simply not have enough capacity for the area you’re asking it to heat.

For example:

• The home may have been extended.
• Open-plan living areas may have increased in size.
• Ceiling heights may have changed.
• Heating expectations may have changed since the system was installed.

Even a perfectly functioning system will struggle if it’s undersized for the space.

A professional assessment can determine whether your system is appropriately sized for your home’s layout and your heating requirements.

11. Your System May Be Due for a Service

Like any appliance, air conditioners perform best when they’re regularly maintained.

Dust, dirt and general wear can reduce airflow and heating performance over time.

During a professional service, our technicians inspect your system to ensure it’s operating efficiently.

If significant dirt has built up inside the indoor unit, we may recommend one of our Eco Clean services to restore airflow and improve overall performance.

What Can You Check Yourself?

Before booking a service, there are a few simple things you can check:

Make sure all vents are fully open.

Confirm the correct zones are turned on.

Clean your air filters.

Close doors to unused rooms.

Remove furniture blocking vents.

Set your heater between 20°C and 22°C.

If one room still refuses to warm up, it may be time for a professional inspection.

When Should You Contact Morphett Air?

If one room consistently stays colder than the rest of your home, the experienced team at Morphett Air can help identify the cause.

We can inspect:

• Your air conditioner and heating performance.
• Zoning settings and zone motors.
• Air balancing throughout your home.
• Ductwork for leaks or damage.

It’s one of the most common questions we receive during winter, especially on those cold Adelaide mornings.

The good news is that, in many cases, your air conditioner is operating exactly as it should.

Here’s why your heater may take a little longer to warm your home.

Reverse Cycle Air Conditioners Don’t Produce Instant Heat

Unlike portable electric heaters or gas heaters that begin producing heat almost immediately, a reverse cycle air conditioner works a little differently.

When you switch your system to heating mode, it first needs to:

• Start the compressor.
• Build refrigerant pressure.
• Warm the indoor heat exchanger (coil).
• Reach a suitable operating temperature before blowing warm air into your home.

Many modern systems deliberately delay the indoor fan for a few minutes so they don’t blow cold air into the room while the system is warming up.

This is completely normal and helps provide a more comfortable heating experience.

Your Home May Be Very Cold

The colder your home is, the longer it will naturally take to reach your desired temperature.

If your house has cooled down overnight, your air conditioner isn’t just heating the air—it also has to warm:

• Walls
• Floors
• Ceilings
• Furniture
• Other surfaces throughout the room

These all absorb heat before the room itself starts to feel comfortable.

This is why heating a home from 12°C to 21°C takes much longer than maintaining a home that’s already sitting at 19°C.

Is Your Air Conditioner the Right Size for Your Home?

One of the biggest factors affecting heating performance is whether your air conditioner has been correctly sized for the area you’re trying to heat.

Every air conditioning system is designed to heat and cool a specific space. If you’re asking a smaller system to heat a much larger area than it was designed for, it will naturally take longer to reach the set temperature—and in some cases, it may never quite get there.

For example, a split system installed to heat a single living room may struggle if you’re expecting it to comfortably heat an open-plan living area, kitchen, dining room and hallway.

It’s also important to consider how you’re using your home today compared to when the system was originally installed.

You may now be trying to heat:

• Additional rooms.
• A home extension.
• Large open-plan areas.
• Rooms with high ceilings.
• Areas with large windows or poor insulation.

Even if your air conditioner is operating exactly as designed, it may simply not have the capacity to meet your current heating requirements.

Are Your Expectations Realistic?

It’s also worth considering what you’re expecting your air conditioner to do.

Many people turn their system on after the house has been cold overnight and expect the entire home to reach 22°C within 10 or 15 minutes.

Unfortunately, that’s generally unrealistic—particularly in larger homes or during very cold weather.

Reverse cycle air conditioners are designed to heat your home efficiently and consistently, maintaining a comfortable temperature over time rather than producing instant heat.

Your System May Be Performing a Defrost Cycle

During colder weather, your outdoor unit can develop frost on the outdoor coil.

To remove this frost and maintain efficient operation, your air conditioner will automatically enter a defrost cycle from time to time.

During this process you may notice:

• Heating temporarily pauses.
• The indoor fan may slow down or stop.
• Steam rising from the outdoor unit.
• Water draining from the outdoor unit.

Once the defrost cycle has finished, your system will automatically return to normal heating operation.

This is a completely normal part of winter operation.

Dirty Filters Can Restrict Airflow

One of the simplest reasons your heater may feel slow is dirty air filters.

When filters become clogged with dust and debris, they restrict airflow, making it harder for warm air to circulate throughout your home.

This can result in:

• Longer heating times.
• Reduced airflow.
• Higher energy consumption.
• Reduced comfort.

Cleaning your filters regularly is one of the easiest ways to keep your system operating efficiently.

The Temperature Setting

A common misconception is that setting your heater to 30°C will warm your home faster.

Unfortunately, it doesn’t.

Your air conditioner heats at the same rate regardless of whether it’s set to 21°C or 30°C.

The higher setting simply tells the system to continue heating for longer.

For most Adelaide homes, we recommend setting your system between 20°C and 22°C for comfortable and energy-efficient heating.

Could Your System Benefit from a Service?

If your heater seems to be taking much longer than it used to, a professional service may help restore its performance.

Over time, systems can lose efficiency due to:

• Dirty filters.
• Dust build-up inside the indoor unit.
• Restricted airflow.
• Worn components.
• General wear and tear.

At Morphett Air, our qualified technicians thoroughly inspect your system to ensure it’s operating safely and efficiently.

If required, we may also recommend an Eco Clean, which removes built-up dirt and contaminants from inside the indoor unit to restore airflow and improve performance.

When Should I Call Morphett Air?

While some delay in heating is perfectly normal, it’s worth contacting a qualified technician if:

• Your home never reaches the set temperature.
• The system only blows cool or cold air.
• Airflow is very weak.
• The unit repeatedly shuts down.
• Error codes appear on the controller.
• The system struggles to heat areas it previously heated comfortably.

These symptoms may indicate your system needs servicing, repair, or that it’s no longer appropriately sized for your home’s current heating requirements.

The good news is that, in most cases, this is completely normal—especially during the colder months when your reverse cycle air conditioner is operating in heating mode.

Here’s why.

Why is there water around my outdoor unit?

When your air conditioner is heating your home, the outdoor unit extracts heat from the outside air.

During cold weather, frost naturally forms on the outdoor coil. To keep your system operating efficiently, it automatically enters a defrost cycle from time to time.

As the frost melts, the resulting water drains from the base of the outdoor unit onto the ground. This often creates puddles or damp patches around the unit.

This is a normal part of your system’s operation and is nothing to be concerned about.

Is water around my outdoor unit normal?

Yes.

It’s completely normal to see:

• Water dripping from underneath the outdoor unit.
• Small puddles forming on the concrete or surrounding ground.
• Damp areas around the unit during or shortly after heating operation.

Many homeowners mistake this for a leak, when it’s actually just condensation and melted frost being drained away.

Why does it happen more in winter?

During winter, your reverse cycle air conditioner spends more time in heating mode.

Colder temperatures increase the amount of frost that can form on the outdoor coil, meaning your system may enter its automatic defrost cycle more frequently.

As a result, you’ll often notice more water around the outdoor unit during the colder months than you would in summer.

When should I be concerned?

While water outside is generally normal, there are a few situations where it’s worth having your system inspected.

Contact Morphett Air if you notice:

• Water leaking inside your home.
• Your system isn’t heating or cooling effectively.
• Your outdoor unit is surrounded by excessive ice that doesn’t clear.
• Error codes appearing on your wall controller.
• Unusual noises or poor performance.

If you’re unsure whether what you’re seeing is normal, it’s always better to ask.

How can I help the water drain away?

There isn’t usually anything you need to do, but it’s a good idea to:

• Keep leaves, mulch and debris away from the base of the outdoor unit.
• Make sure the area around the unit isn’t blocked.
• Avoid placing objects underneath the unit that could prevent water from draining freely.

Allowing the water to drain naturally helps your system continue operating efficiently.

Regular servicing keeps your system performing at its best

Routine maintenance helps ensure your air conditioner continues to operate efficiently throughout winter and all year round.

During a service, our qualified technicians inspect your system, check its operation, and identify any issues before they become costly repairs.

Regular servicing can help:

• Improve efficiency.
• Reduce running costs.
• Extend the life of your air conditioner.
• Keep your home comfortable all year round.
