Split System AC Repair Lutwyche: Heating Fixed
Is Your Air Con Blowing Cold Air When It Should Be Heating?
Is there anything worse than waking up on a chilly morning, grabbing the remote to warm up the house, and realising your air conditioner is refusing to cooperate? Instead of a warm, cosy breeze, you are met with lukewarm air – or worse, nothing at all.
For homeowners, a reliable heating system is essential when the temperature drops. Recently, the team at Fallon Solutions attended a property in Lutwyche to assist a local resident facing this exact frustration. They had a multi-unit setup where one critical unit had failed, and others were overdue for attention.
Here is how we handled the diagnosis, repair, and maintenance to get their home comfortable again.
The Problem: A Fujitsu Unit Not Heating
The customer called us with a clear issue: their Fujitsu split system was not heating. While the fan was running, the unit was failing to produce warm air, leaving the room uncomfortably cold.
In addition to the broken unit, the homeowner noted that they had two other split systems in the house that hadn’t been looked at in quite some time. They wanted to ensure these units were operating efficiently before they developed similar faults.
Signs Your Air Con Is Not Working Correctly
If you are wondering whether your system needs an air conditioner repair, look out for these common symptoms that our Lutwyche customer experienced:
- Inconsistent Temperature: The unit blows air, but it never reaches the set temperature.
- Weak Airflow: You can hear the fan, but the air pressure is low, often caused by blockages.
- Strange Noises: Grinding, rattling, or hissing sounds often indicate mechanical failure or gas leaks.
- High Energy Bills: A unit struggling to heat will work twice as hard, spiking your electricity costs.
If your system is stuck in cooling mode or simply won’t heat, it requires professional diagnosis.

The Solution: Diagnosis, Repair, and Service
Upon arrival in Lutwyche, our technician conducted a thorough inspection of the faulty Fujitsu unit. We specialise in split system ac repair Lutwyche residents can rely on, which means we look for the root cause rather than just applying a “band-aid” fix.
Step 1: Fixing the Heating Issue
The primary unit was diagnosed with a fault preventing the reverse cycle function from engaging. In simple terms, a reverse cycle air conditioner uses a component to switch the flow of refrigerant, allowing it to pump heat into the room rather than removing it. When this fails, the unit cannot switch from cooling to heating.
Our technician identified the specific component failure within the HVAC system. We repaired the heating mechanism, tested the refrigerant pressures to ensure they were within the manufacturer’s specified range, and verified that the unit was blowing hot air at the correct capacity.
Step 2: Servicing the Additional Units
The job didn’t end with the repair. Regular servicing is often overlooked, but it is vital for longevity. For the two working units, we performed a comprehensive service. This involved:
- Deep Cleaning the Filters: We removed dust and particulate build-up that chokes the system and reduces air quality.
- Coil Inspection: We checked the evaporator and condenser coils. Dirty coils reduce the system’s ability to absorb or release heat, making the motor work harder.
- Drain Flushing: Blocked drains are the number one cause of water leaks in split systems. We flushed the condensate drains to prevent future water damage to the customer’s walls.
By the time we left, the faulty unit was heating perfectly, and the other two units were running cleaner and quieter than before.
The Benefits for the Homeowner
By addressing both the immediate breakdown and the maintenance of the other units, this Lutwyche homeowner gained more than just a warm room.
- Restored Comfort: The primary living space is now warm and inviting, perfect for the cooler months.
- Improved Energy Efficiency: Serviced air conditioners run much more efficiently. By cleaning the filters and coils on the two additional units, the homeowner can expect lower electricity bills this quarter.
- Extended Lifespan: Catching minor issues during a service prevents them from turning into major, expensive repairs later on.
- Better Air Quality: Removing dust and mould spores from the filters ensures the family is breathing cleaner air.
