Yes, eligible Victorian homeowners can access rebates via the Victorian Energy Upgrades (VEU) program when replacing inefficient systems with approved reverse cycle units[cite: 76, 77]. Climatic can guide you through eligibility[cite: 79].

Can I control my air conditioner from my smartphone?

Yes, many modern systems feature built-in Wi-Fi connectivity, allowing you to control temperatures, schedules, and energy usage from your smartphone[cite: 81, 82, 83].

Why is my air conditioner not turning on?

Check whether the system has power. Confirm that the wall isolator is switched on, the controller or remote has working batteries, and the relevant circuit breaker or safety switch has not turned off. If the controller is blank or the indoor unit does not respond, do not open electrical covers. If the circuit breaker or safety switch turns off again after being reset, leave the system off and contact a licensed electrician or air conditioning technician.

Why is my air conditioner running but not cooling?

Check that the system is set to COOL mode and that the selected temperature is lower than the room temperature. Close external doors and windows, clean accessible filters, check indoor airflow, and ensure the outdoor unit is not obstructed. If the unit runs continuously without reducing the room temperature or cooling performance has suddenly declined, arrange professional testing.

Why is my reverse cycle air conditioner not heating?

Confirm that the system is set to HEAT mode and select a temperature above the current room temperature. Reverse cycle systems may briefly delay the indoor fan while the coil warms and may pause during normal defrost cycles. Check filters and outdoor airflow. Arrange a service if the system continues blowing cool air or cannot reach the selected temperature.

Why does my air conditioner temporarily stop heating in winter?

The system may be completing a normal defrost cycle. During defrosting, indoor and outdoor fans may stop while frost is removed from the outdoor heat exchanger. Heating should resume automatically. Arrange a service if defrosting becomes unusually frequent, lasts much longer than normal, or heating performance remains poor.

Why is the airflow from my split system or ducted vents weak?

Weak airflow can be caused by dirty filters, low fan speed, blocked supply vents, an obstructed return-air grille or incorrect ducted zone settings. Clean only accessible user-serviceable filters. If airflow remains weak, the indoor coil, fan, zone damper or ductwork may require professional inspection.

Why is one room not heating or cooling properly with ducted air conditioning?

Check that the room or zone is enabled on the controller and that its supply-air grille is open and unobstructed. Check the return-air filter and system settings. If one room remains noticeably different from the rest of the property, the cause may involve zone controls, a damper, damaged ductwork, air leakage or airflow balancing and should be professionally inspected.

Why is one indoor unit in my multi-head system flashing and not operating?

Check that all indoor units connected to the same outdoor unit are set to the same operating mode. Multi-head systems generally cannot heat one room while cooling another. If all indoor units are already set to the same mode and one continues flashing, record the flashing-light pattern and arrange a service.

Why does my air conditioner keep turning on and off?

Some cycling is normal with inverter air conditioners. Frequent short cycling may be caused by dirty filters, restricted airflow, timer settings, controller or sensor issues, incorrect system sizing, or electrical or refrigeration faults. Arrange a service if the system starts and stops every few minutes or cannot maintain comfort.

Why is water leaking or dripping from the indoor unit?

Turn the system off if water is dripping from the indoor unit, ductwork or ceiling. Possible causes include a blocked or damaged drain, failed condensate pump, restricted airflow, a frozen coil or another internal fault. Do not dismantle the unit or use chemicals in internal drains. Arrange professional inspection.

Is water or frost around the outdoor unit normal?

Some water beneath the outdoor unit and light frost can be normal during heating and defrost operation. Heavy ice that remains, water entering the building, hazardous drainage or leaks from unusual locations should be investigated. Do not chip ice from the coil or pour hot water over the outdoor unit.

Why is my air conditioner making an unusual noise?

Brief clicks and normal airflow sounds can occur during operation. New, loud or persistent rattling, grinding, scraping, squealing, buzzing or strong vibration may indicate a fan, motor, bearing, electrical or compressor-related fault. Turn the system off if the noise is severe or accompanied by a burning smell, poor performance or water leakage.

Why does my air conditioner smell musty, stale or like it is burning?

Musty or stale smells may be caused by dust, moisture or microbial growth on filters, coils, fans or drainage components. Clean accessible filters according to manufacturer instructions. A persistent burning, melting-plastic or electrical smell may indicate overheating or an electrical fault, so switch the system off and arrange professional inspection.

Why is my air conditioner remote control not working?

Replace the batteries, confirm they are installed correctly, point the remote at the indoor unit and check for obstructions. Check whether a timer, lock or controller setting is active and confirm the operating mode. Refer to the model-specific manual if the unit still does not respond.

What should I do when an operation light is flashing or an error code appears?

Record the full error code, controller message or flashing-light pattern before switching the system off. Note which units are affected and whether the problem occurs in heating, cooling or both. Do not repeatedly reset an unresolved fault. Provide the exact error code and model number when booking a service.

Why has Mitsubishi Electric Wi-Fi Control stopped working?

Check that the internet connection and router are working, the air conditioner has power and the Wi-Fi Control app is logged in. Re-pairing may be required after a router replacement, network name change, password change or network reset. Use the Mitsubishi Electric instructions for the specific adaptor.

Why has my air conditioning electricity use increased?

Higher electricity use may result from longer operating hours, extreme weather, very high or low temperature settings, dirty filters, blocked airflow, open doors and windows, poor insulation or conditioning more rooms. Arrange a maintenance check if electricity use rises significantly without a corresponding change in weather or usage and performance has also declined.

How often should I clean the filters and have the system serviced?

Follow the maintenance schedule in the manufacturer manual. For many wall-mounted Mitsubishi Electric systems, filters should be checked and cleaned approximately every two weeks during heavy use. A yearly professional service is a practical starting point for many residential systems, while commercial or heavily used systems may need more frequent servicing.

When should I stop troubleshooting and call a technician?

Stop using the system and arrange professional assistance for repeated circuit-breaker or safety-switch trips, smoke, sparks, persistent burning smells, electric shock or tingling, water near electrical parts, major indoor leakage, loud grinding noises, heavy ice that does not clear, recurring error codes or complete loss of heating or cooling after basic checks.

Why is my air conditioner not turning on?

Check whether the system has power. Confirm that the wall isolator is switched on, the controller or remote has working batteries, and the relevant circuit breaker or safety switch has not turned off.

What Is Reverse Cycle Air Conditioning?

Reverse-cycle air conditioning is a system that both heats and cools your home. In winter, it draws heat from the outdoor air, even on cold nights, and moves it inside. In summer, it reverses the process and removes heat from your rooms. Because it moves heat rather than generating it, a reverse cycle system typically delivers three or more units of heat for every unit of electricity it uses.

How it works

The refrigerant absorbs heat through the outdoor coil, the compressor pumps it to the indoor fan coil unit, and the unit releases the warmth into the room. Reversing the refrigerant flow provides cooling.

Why homeowners choose it

Lower running costs than portable, panel and off-peak storage heaters, which heat with electric elements
One system for year-round heating and cooling
Built-in air filtration and dehumidification

Our Residential AC Solutions

Split AC Systems

Split systems are permanently mounted with the condenser/compressor unit located externally and a separate evaporator/fan coil unit inside the home. These are joined together by insulated piping, which carries the refrigerant. The remote location of the compressor makes these units significantly quieter than window or wall units. The internal unit of a split system is most commonly installed on a wall. However, units can be installed at floor level, ideal for heating, in the ceiling as a cassette or ducted system.

Multi-Head AC Systems

Multi-systems are split systems with more than one internal unit connected to an external compressor. There are multiple indoor styles and capacity combinations available. These systems have individual on, off, and temperature controls.

Ducted AC Systems

Ducted systems are designed to centrally heat and cool a large number of rooms or an entire home. They can be suitable if you have an open-plan house and prefer heating or cooling in all or most of the rooms in your house simultaneously.

Multi-Pump Systems

The CITY MULTI PUMY-SP Series air conditioning system allows the connection of multiple indoor units to a single outdoor unit. Choose from CITY MULTI indoor units using the standard branch pipework, M-S-P series indoor units via a multi split system branch box, or a combination of both for selection convenience.

Ceiling Cassettes

Ceiling cassette air conditioning systems are an ideal option for air-conditioned rooms where there are no available walls to mount a split system or where there is limited ceiling space for a ducted system. Its whisper-quiet operation is ideal for master bedrooms, living rooms and other single-room residential or commercial uses.

Bulkhead AC Systems

Where air conditioning installation is not possible due to a lack of wall space or concrete ceilings, a bulkhead can be created to house the SEZ system. Its quiet operation makes it suitable for bedrooms, living rooms and other single-room residential or commercial uses.

Wall Mounted AC Units

The range of wall-mounted reverse cycle split system air conditioners includes inverter and non-inverter models, suitable for single rooms through to larger open plan living areas. As a leader in air conditioning technology, Mitsubishi Electric has introduced new features such as Plasma Duo filter systems, i-see Sensor and Catechin filters.

Residential Air Conditioning Installation FAQs for Geelong Homeowners

What size air conditioner do I need?

Choosing the correct air conditioner size is one of the most important factors in achieving year-round comfort and energy efficiency. The right size depends on your home's floor area, ceiling height, insulation, window placement, and how you use each room. A system that's too small will struggle to maintain the desired temperature, while an oversized system may use more energy than necessary and cycle on and off too frequently.

During a home consultation, Climatic technicians assess these factors to recommend the most suitable air conditioning system for your home.
Should I choose a split system or ducted air conditioner?

The best option depends on your home's layout, budget, lifestyle and heating and cooling requirements.

A split system is ideal if you want to heat or cool a single room or a specific area of your home. It is generally more affordable to install and operate than a whole-home system.

A ducted air conditioner is designed to heat and cool multiple rooms throughout the home while providing a discreet appearance with ceiling or floor vents. It is often the preferred choice for larger homes or homeowners wanting whole-home climate control.
How much does it cost to install an air conditioner in Geelong?

The cost of installing an air conditioner depends on the type of system, the size of your home, the installation complexity and any electrical or building work required. Requesting a detailed quote ensures you understand exactly what's included before installation begins.

Climatic provides free, no-obligation quotations throughout Geelong and surrounding suburbs.
How long does air conditioner installation take?

Most split system air conditioner installations take around 4 to 6 hours. Larger or ducted air conditioning systems may require one or more days, depending on the property's layout and the amount of ductwork involved.

Before installation begins, your installer should provide an estimated timeframe so you know what to expect.
What is the most energy-efficient air conditioner for my home? Can I use it for both heating and cooling?

Reverse cycle air conditioners are among the most energy-efficient heating and cooling systems available for Australian homes. They provide cooling during summer and heating during winter using the same system.

Instead of generating heat like traditional electric heaters, reverse cycle systems transfer heat from the outside air, making them significantly more energy efficient and helping reduce winter running costs.

Choosing the correct size and using the system efficiently will maximise both comfort and energy savings.
Can one air conditioner cool my entire house?

It depends on the size and layout of your home. A single split system may effectively cool an open-plan area or smaller home, but it usually won't provide even temperature control across several closed rooms. For whole-home heating and cooling, a ducted or multi-split system may be a better fit. A home assessment can determine the most efficient option based on your layout and comfort requirements.
Which air conditioner brand do you recommend?

There isn't one air conditioner brand that's right for every home. The best choice depends on your home's size, layout, budget and heating and cooling requirements.

Mitsubishi Electric is widely recognised for its reliability, energy efficiency and long-term performance, while Panasonic is another trusted brand offering excellent value and quality.

Every homeowner has different priorities and budgets. Comparing features, warranty, energy efficiency and long-term running costs is often more important than choosing a particular brand.

As a Mitsubishi Electric Diamond Dealer, Climatic can help you compare different systems and recommend the most suitable option for your home.
Do I need council approval to install a home air conditioner?

In most homes across Geelong and surrounding areas, council approval isn't required to install an air conditioner.

However, there may be exceptions for heritage-listed properties, apartments, homes affected by planning overlays or where body corporate requirements apply.

If approval is required, your installer should advise you before any installation work begins.
Are there rebates for a new air conditioner in Victoria?

Yes. The Victorian Energy Upgrades (VEU) program offers discounts on approved high-efficiency reverse cycle air conditioners. The amount depends on your property, your existing heating and cooling, and the model installed. Climatic can check whether your home is eligible and explain your options.
How often should my air conditioner be serviced?

Most manufacturers recommend servicing a residential air conditioner at least once every 12 months.

Regular servicing helps maintain energy efficiency, improves indoor air quality, extends the life of the system and reduces the likelihood of unexpected breakdowns.

If your air conditioner is used frequently throughout the year, more regular servicing may be beneficial.
What happens during an air conditioner installation?

Most residential air conditioner installations follow four simple steps:

1. Home assessment
The installer assesses your home or building plans to understand your heating and cooling requirements.

2. System recommendation
A suitable air conditioning system is recommended based on your home's layout, budget and comfort needs.

3. Professional installation
Licensed technicians install the indoor and outdoor units, complete all electrical connections and test the system.

4. Testing and handover
The installer demonstrate how to operate your new air conditioner, explains Wi-Fi controls (where applicable) and provides any required compliance certificates.

At Climatic, we also ensure every customer is comfortable using their new system before we leave.

Victorian Energy Upgrades (VEU) Discounts for Reverse Cycle Air Conditioning

Victorian households can receive an upfront discount when they install an approved, high-efficiency reverse cycle air conditioner through the Victorian Energy Upgrades program. Discounts can reach up to $1,610 off upfront costs, with a further discount of up to $5,530 possible when an existing ducted gas heating system is replaced with an efficient ducted reverse cycle system. The exact amount depends on your existing heating, the size of the new system, and the model you choose, and only approved models qualify. Renters need landlord approval for heating and cooling upgrades. Climatic can check whether your home qualifies, recommend an eligible system, and show the discount on your quote.
