The last thing the family needs is a faulty heater in the middle of winter. Melbourne’s weather fluctuates quickly, and a working heater provides consistent comfort throughout the year. 

Although heating systems are high-performing, it’s good to be aware of how to identify minor issues and the steps to fixing them early. Whether users recently installed gas ducted heating, a split system, or a ducted reverse cycle heating and cooling system, this article will explore signs of immediate repair, giving users insight into what system will suit their needs.

Importance of a Functioning Heating System

Why is a functioning heating system essential for residential or commercial property?

1. Energy efficiency and environmental impact

Accounting for a large proportion of energy usage in buildings, a functioning heating system – whether split system, reverse cycle, or ducted heating- cuts back operational costs and greenhouse gas emissions.

2. Indoor air quality and building integrity

Excessive moisture can lead to mould growth and damage to the building structure

A functioning heater can protect the property from damage by directly influencing the air quality in homes or commercial properties. 

Excessive moisture can lead to mould growth and damage to the building structure. For example, wet winter months require a dehumidifier function to correct and stabilize moisture levels.

3. Commercial space productivity

Temperature and air quality impact worker productivity, so clean, conditioned air contributes to a comfortable and efficient working environment.

A quality heating system is also critical in healthcare, restaurants, and other settings, controlling and reducing odors and preventing safety hazards.

4. Regulatory compliance

Functioning split systems, ducted reverse cycle heating, and gas ducted heating must meet building regulations and indoor air quality and energy consumption standards. Failing to meet these standards results in penalties or legal issues.

For example, the National Construction Code (NCC) sets the minimum requirements for building construction, design, and performance across Australia. The NCC specifies certain standards regarding energy efficiency, health concerns, and more. The Australian Standards (AS) also offer guidelines for HVAC standards, such as AS 1668.2-2012, governing the use of ventilation and air conditioning in buildings.

5. System longevity and cost-effectiveness

Regular maintenance prevents minor issues from escalating, saving users money

Keeping the heating system maintained ensures its longevity.

Regular maintenance prevents minor issues from escalating, saving users money on maintenance and heater repair costs in the long run.

Signs Gas Ducted Heating Needs Repair

What are some clear telltale signs that the gas ducted heating system needs a professional inspection?

Uneven heating

Feeling a warm, cozy feeling vanishing is frustrating. Uneven heating in different areas of the home means there’s a high chance the ductwork is damaged.

Responsible for transferring hot air around the property, duct leakage means that warm air is escaping from these openings.

Yellow pilot light

the ducted gas heating system should always have a blue pilot light. If it is yellow or flickering, there could be an issue with the gas line or combustion process.

Not only can this reduce the system’s efficiency, but it also poses health and safety risks. If the user notices a yellow pilot light, speak to an Aust Climate technician to have the combustions and gas pressure checked.

Frequent cycling

Users don’t want to increase wear and tear on components with constant cycling, so don’t be afraid

Does the gas ducted heater turn off and on frequently? This could be a sign of a malfunctioning thermostat, overheating, or poor airflow.

Users don’t want to increase wear and tear on components with constant cycling, so don’t be afraid to speak to a professional for guidance.

Poor air quality

If dust and debris come from the vents, gas-ducted heating filters could need cleaning. Dirty filters and ductwork circulate pollutants and allergens in the home, cutting back air quality. Commit to regular filter changes and duct cleaning!

The ducted heating system circulating these allergens can cause increased allergy symptoms such as sneezing and coughing or respiratory problems such as asthma. Inspect and clean the system to improve indoor air quality.

Unpleasant smells

If users notice a burning smell, this could be dust burning off after the gas ducted system has been inactive or more serious issues such as electrical faults or overheating components.

Likewise, if the user suspects the smell is gas, turn off the heating system immediately and call a technician. Never ignore the smell of gas in the home.

Signs a Split System Needs Repair

Although a split system is less complex than ducted reverse cycling heating and cooling or a multi-head system, it can still require maintenance and repair.

Let’s look at some of the most common signs.

It’s making weird noises

In some cases, vibrations and increased noises are caused by incorrect indoor or outdoor unit mounting

A split system’s quiet humming is comfortable, but if it makes odd noises such as rattling, gurgling, or grinding, it’s often a sign to book a repair and maintenance service as soon as possible. The split system could have loose or damaged fan blades, compressors, or motor mounts.

It could be a mechanical failure or damage if the system makes these sounds. In some cases, vibrations and increased noises are caused by incorrect indoor or outdoor unit mounting. A professional can ensure they are level and stable.

It smells strange

If users notice a musty, burning smell coming from the split system, moisture and mildew could be trapped in the system, forming mould.

Chemical smells can come from a refrigerant leak or foul odors from pest infestations. Smells can also be caused by electrical faults, such as components failing or overheating motors or wiring. Users don’t want a fire hazard.

It’s taking longer to cool

Do users prefer to keep the room cool, even during the chilly months? An old system, unclean air filters, an outdoor unit cluttered with debris, or a malfunctioning thermostat can cause an inconsistent temperature. The compressor, blower motor, or evaporator coil can sometimes be problematic.

Users should feel the cooling in minutes, but if it’s taking longer than it usually does, it’s time for a service. A drop in cooling efficiency often is due to blockages, faulty parts, or a loss of refrigerant.

Signs Ducted Reverse Cycle Heating and Cooling Needs Repair

How do users know if the ducted reverse cycle system needs a quick fix?

Inconsistent airflow

The ductwork system delivers heating and cooling, and it can leak or block up dust or debris, affecting airflow distribution

Does one bedroom feel colder than the others? The ducted reverse cycle system could have zone control issues, such as faulty dampers or a malfunctioning control panel. The ductwork system delivers heating and cooling, and it can leak or block up dust or debris, affecting airflow distribution.

Seals can also wear out, leaking ducts, causing conditioned air to escape before reaching the intended room and creating cold and hot spots around the home. Thermostat malfunctioning or blockages also slow air movement or redirect it, causing uneven cooling.

Unusual noise

A peaceful operation means a functioning air conditioner, but strange noises will require a specialist opinion. 

Rattling sounds from the outdoor unit can be caused by sticks, leaves, and signal loose parts. Grinding sounds suggest compressor problems or worn motor bearings for the ducted reverse-cycle system. Whistling noises imply a refrigerant leak and are potentially hazardous.

Moisture or leaks

Have users spotted moisture around the central indoor unit in the roof space or leaks around the outdoor compressor?

Dampness can indicate further problems with refrigerated cooling or structural damage to the home. Likewise, a build-up of ice formations on the ducted reverse cycle system can cause more leakage.

A sudden spike in energy bills

Increasing energy bills is a crystal-clear sign of malfunctioning for split systems, gas ducted heating

If the reverse-cycle system uses more power than it needs to, it isn’t as efficient as it should be. User may not be an obvious sign as it’s gradual, so having the heating elements checked at least once a year is critical.

If users would like to learn more, have a read about how to replace the gas heater with electric heating and cooling. Increasing energy bills is a crystal-clear sign of malfunctioning for split systems, gas ducted heating, and reverse-cycle heating systems. It’s important to book a service for all heating and cooling models twice a year or at least once annually.
