Valley Air Conditioning Resolves Whirring Noise in Hitachi Air Conditioner at Tenambit

At Valley Air Conditioning, we pride ourselves on delivering high-quality service and efficient solutions for all kinds of air conditioning issues. Recently, our team was called out to a service request in Tenambit for a Hitachi 3.5kW split system air conditioner that was experiencing a persistent whirring noise. The homeowners were concerned about the unusual sound coming from the unit’s fan, fearing that it might lead to more significant problems if left unchecked. After a thorough inspection, we identified the root cause of the issue as faulty motor windings. With our expertise, we not only fixed the problem but also performed a comprehensive chemical clean to ensure optimal performance.

Initial Air Conditioner Assessment

A Troublesome Whirring Noise

When we arrived at the Tenambit residence, the customer greeted us with relief, eager to resolve the whirring noise that had disrupted their air conditioning system. The Hitachi 3.5kW air conditioner, a popular model known for its energy efficiency and reliability, had served the household well. However, over time, it began emitting a loud, distracting noise from the fan whenever it was turned on. The homeowners had attempted some basic troubleshooting, such as cleaning the air filters and inspecting the outdoor unit for debris, but the noise persisted.

As with any service call, our first step was to conduct a thorough inspection. Listening to the sound and examining the unit, we quickly confirmed that the issue was originating from the indoor fan. The whirring noise was particularly noticeable when the fan was set to higher speeds, which suggested that the problem was likely related to the fan motor or its components.

Air Conditioner Diagnosis

Faulty Motor Windings

Upon closer inspection, we identified that the root cause of the noise was the motor windings within the fan motor. Motor windings are an essential part of the air conditioner’s motor system, responsible for generating the magnetic fields that cause the motor to spin. When these windings start to deteriorate or become damaged, the motor struggles to function properly, often resulting in unusual noises, such as the whirring sound the homeowners were hearing.

In this case, the windings had suffered wear over time, which is a common occurrence in air conditioning systems that have been in use for several years. As the windings degrade, the motor can become imbalanced, leading to friction and noise during operation. If left unresolved, this issue could have caused further damage to the motor or other components of the air conditioning system, potentially resulting in more extensive repairs or even the need for a complete replacement.

The Air Conditioner Repair Process

Once we identified the issue, we carefully disassembled the air conditioner to access the fan motor. After confirming the faulty windings, we replaced the necessary components, ensuring that the motor would operate smoothly and quietly moving forward. Replacing the windings not only eliminated the immediate noise but also improved the overall efficiency of the system, as the motor could now function without the added strain caused by the imbalance.

Our skilled technicians ensured that all components were securely reassembled and that the fan was functioning correctly before proceeding to the next crucial step: a chemical clean of the air conditioner.

Chemical Cleaning the Air Conditioner for Optimal Performance

While the primary issue was the faulty motor windings, we took the opportunity to perform a thorough chemical clean of the entire air conditioning unit. Over time, dust, dirt, and mould can accumulate within the system, particularly on the evaporator coils and fins, reducing efficiency and potentially leading to poor air quality.

A chemical clean is a deep-cleaning process that uses specialised cleaning solutions to break down and remove stubborn dirt, mould, and bacteria from the air conditioner’s internal components. This process not only restores the unit’s cooling capacity but also improves the quality of air circulating through the system.

For the Hitachi 3.5kW unit, we applied a chemical cleaning solution to the evaporator coils, fins, and other key components, ensuring that all debris and buildup were removed. This process is particularly important in split system air conditioners, as the accumulation of dust and dirt can restrict airflow, forcing the system to work harder and increasing energy consumption. After the chemical clean, the air conditioner was running more efficiently, and the homeowners could enjoy cleaner, fresher air.

Post-Service Testing and Customer Satisfaction

After completing the repairs and chemical clean, we thoroughly tested the air conditioning system to ensure it was operating at peak performance. The whirring noise was completely gone, and the fan motor was functioning smoothly. The cooling capacity of the unit had improved, and the airflow was unrestricted, thanks to the chemical clean.

The homeowners were delighted with the results. Not only had the annoying noise been resolved, but the air conditioner was now running more efficiently than before. They expressed their gratitude for our prompt and professional service, particularly appreciating the extra step of the chemical clean, which they hadn’t initially requested but were happy to have received.
