What to Consider When Choosing an Air Conditioning Unit for Your Home

What to Consider When Choosing an Air Conditioning Unit for Your Home

We got through another scorching summer—that public holiday weekend, with consistent temperatures near 40 degrees, we had customers across Melbourne calling in—they needed air conditioning!

Don’t leave it until you’re sweltering in your living room. Autumn in Melbourne is the perfect time to consider the effectiveness of your air conditioning system. Precision Refrigeration understands the importance of a comfortable living space, which is why we’ve put together this comprehensive guide to help you make an informed decision about air conditioning for your home.

Before selecting an air conditioning system, it’s crucial to understand the unique characteristics of your home. Here are some factors to consider:

  • Orientation: The direction your home faces can significantly impact its temperature. North-facing rooms tend to be warmer, requiring more cooling.
  • Size: The size of the area you want to cool will determine the capacity of the air conditioner you need.
  • Insulation: Well-insulated homes retain cool air better, reducing the workload on your air conditioner.
  • Windows: Large or poorly insulated windows can let in heat, affecting the efficiency of your cooling system.
  • Ceiling Height: Higher ceilings require more cooling capacity as there’s more space to cool.

For example, you live in a north-facing property with large, single-glazed windows that trap the late afternoon sun. Those rooms are going to get pretty warm, especially in the summer, and could likely benefit from a larger system.

A property with low ceilings, south-facing, double-glazed windows and efficient insulation may require a much smaller air conditioning unit.

Here’s how to keep your house cool while keeping your bills down. 

Perhaps you need a heat load assessment…

What is a Heat Load Assessment?

A heat load assessment takes into account various factors, such as the size of your home, the number of occupants, and the type of appliances used. This assessment helps determine the right size and type of air conditioning system for your home.

For assistance with a heat load assessment, ask our air conditioning experts. We are happy to help. 

Location and Structure

In addition to the factors above, like insulation and orientation, you’ll need to consider the local climate and the building materials of your home. 

Whole Home or a Single Room:

Do you need to cool your entire home or just a single room?

Whole-home systems provide consistent comfort throughout the house, while single-room solutions can be more cost-effective if you only need to cool a specific area.

a single air conditioning unit

Choosing the right air conditioning for your home in Melbourne will depend on – your space’s characteristics, a heat load assessment, location, and whether you need a whole-home or single-room solution. 

Don’t wait until we’re back in summer and you’re melting in on your engineered timber floor. 

Whatever your needs, Precision Refrigeration is here to assist you every step of the way, ensuring you stay cool and comfortable during our hot summers.

When To Repair Your HVAC System And When To Replace It

When To Repair Your HVAC System And When To Replace It

Choosing Between Repairing & Replacing Your HVAC System

If you run or manage a commercial building, you’ll know that maintaining an optimal indoor environment is crucial for both productivity and efficiency. And central to ensuring that the building runs smoothly is your HVAC system. It operates as the backbone of your building’s climate control, ensuring a comfortable atmosphere for employees and clients. And, as a complex mechanical system, it’s subject to wear and tear. If you’re in a situation where your HVAC system is getting a little rickety or is underperforming and generating costly ad hoc repairs, the question arises: should you repair or replace your HVAC system?

A repair might resolve short-term problems and might appear to be the most cost-effective option, but it could be a band-aid on a larger, more systemic issue. Conversely, replacing an HVAC system represents a significant investment. Yet, it could lead to improved energy efficiency, lower maintenance costs, and more reliable climate control in the long term.

Whether you oversee a small commercial space or a large corporate facility, understanding the dynamics of repairing versus replacing your HVAC system is vital.

How HVAC systems work

A commercial HVAC system consists of a heating unit, like a furnace or boiler, that warms the air or water distributed throughout the building via ducts or pipes. The ventilation component ensures the exchange of indoor air with outdoor air to remove pollutants and regulate humidity. 

Air conditioning is achieved by extracting heat and moisture from indoors through a compressor and evaporator system that circulates cooled air. 

The entire system is controlled by thermostats, allowing precise temperature quality control. Additionally, air filtration mechanisms are integrated to remove dust and particulates, ensuring clean indoor air. The distribution system, comprising ductwork, vents, and radiators, ensures even delivery of conditioned air or heat throughout the building, maintaining a consistent and comfortable environment.

We have a great blog post about the different HVAC systems available for commercial buildings, so we recommend you check that out.

Signs of HVAC Wear and Tear

The following are typical signs of wear and tear on commercial HVAC systems:

  1. Inconsistent Temperatures: If different areas of the building experience varying temperatures or if the HVAC system struggles to maintain the set temperature, it could indicate issues with the system’s efficiency or distribution components.
  2. Noises: Sounds like rattling, buzzing, grinding, or whistling from the HVAC system are not normal. These noises can indicate mechanical problems, loose components, or issues with the blower or motor.
  3. Increased Energy Bills: A spike in energy bills without a corresponding increase in usage could suggest the HVAC system is working harder than usual to maintain temperatures, indicating inefficiency or malfunction.
  4. Frequent Repairs: If the system requires frequent repairs, it’s a sign of aging and deterioration. 
  5. Poor Air Quality: can signal issues with the HVAC system, especially its ability to filter and ventilate air properly.
  6. Reduced Air Flow: Weak airflow from vents could indicate problems with the system’s blower, ductwork obstructions, or other issues restricting air movement.
  7. System Age: HVAC systems typically have a lifespan of around 15-20 years. If your system is approaching or has exceeded this age, signs of wear are more likely, and its efficiency is probably reduced.
  8. Thermostat Issues: If you frequently need to adjust the thermostat to keep the building comfortable, or if the thermostat doesn’t seem to respond accurately, it could indicate a problem with the control system or the HVAC unit itself.
  9. Moisture or Leakage Issues: Signs of moisture around the system, like leaks or pooled water, can be a symptom of a refrigerant leak or a problem with the condensate drain.
  10. Strange Odours: Unusual smells coming from the HVAC system can indicate a range of problems, from mould or mildew in the ducts to burned-out electrical components.
The Costs of Repairing Vs Replacing Your HVAC System

The cost of repairing an HVAC system in Melbourne varies depending on the type of system and the nature of the issue. For different types of air conditioning systems. 

At a minimum, for a basic repair, you’re looking at a cost of $X (to be provided by the client). This will include labour. 

An HVAC professional will need to assess the problem, provide a quote for the work, and complete the repair. This could be as quick as an hour, or it could take weeks, depending on the fix required. 

The cost of replacing an HVAC system in Australia in 2024 can vary significantly based on several factors, including the type of system, size, brand, and installation complexities. Not to mention, commercial buildings come in all shapes and sizes. You could be looking at anything from $2,500 to $50,000 (client confirmation needed)

Technological Advancements in HVAC Systems

Modern HVAC units are now equipped with sophisticated technologies like smart thermostats, Wi-Fi integration, and energy-efficient designs, offering enhanced control, improved energy usage, and better overall performance. These advancements allow for more precise temperature control, remote monitoring, and predictive maintenance, leading to reduced operational costs and increased longevity of the system.

On the other hand, the cost of upgrading to a technologically advanced system might be prohibitive, especially if the existing system is relatively young and can be effectively repaired. In such cases, integrating smaller upgrades, like smart thermostats, into an existing system could be a more viable solution.

Maintenance Tips to Extend the Life of Your Existing HVAC System

If you opt to repair your existing system, the following maintenance tips will help keep it running for longer.

  1. Change your filters regularly to ensure they’re clean and the system works efficiently
  2. Seasonal inspections. Choose an HVAC service professional to inspect your HVAC system. They can also check your filters, refrigerant levels, and clean components.

The Different Types of HVAC Systems for Commercial Buildings

TheThe Different Types of HVAC Systems for Commercial Buildings

You’ve found this article because you own or manage a commercial building, and you’re researching your options for commercial HVAC systems. Well done! You’ve come to the right place.

We’re going to highlight the three primary types of HVAC systems available in the market today (for commercial properties). We’ll lay out their unique features, benefits, and potential drawbacks, giving you the knowledge you’ll need to assess which system might be right for the business you have in mind.

Whether you’re installing a new system or upgrading an existing one, the right choice can lead to substantial savings in energy and maintenance costs while also ensuring optimal comfort.

Finally, we will look at an essential part of your decision-making process—something often neglected—the lifespan of these systems. Understanding how long an HVAC system is expected to last and what factors influence its longevity is essential for planning maintenance schedules and budgeting for future replacements.

So, let’s stop with the preamble and dive right in.

The Types of HVAC Systems Available for Commercial Buildings:

1) Single Split Systems:

Description and How They Work

Single split systems are among the most popular and cost-effective HVAC solutions for small to medium-sized commercial buildings. They contain two main components: an outdoor unit containing the compressor and condenser and an indoor unit that houses the air handler and evaporator. The indoor and outdoor units are connected by a conduit carrying refrigerant and power lines.


Single-split systems are ideal for small commercial spaces such as individual offices, shops, or cafes. Their biggest advantage lies in their simplicity and affordability. Each indoor unit operates independently, which means different rooms can have different temperatures, catering to varying comfort needs.

They’re easy to install and do not require extensive ductwork.

Potential Limitations

They’re inefficient for large commercial spaces due to the need for multiple outdoor units.

2) Multi-Split Systems:

Description and How They Work

Multi-split systems are an advanced version of the single split system. They address the limitations of the smaller systems, particularly in terms of scalability. Multiple indoor units are connected to a single outdoor unit. This setup allows for individual control of the temperature in different rooms or zones within a commercial building but with fewer outdoor units needed. Utilising space more effectively.


Multi-split systems are more suited to larger commercial spaces like medium-sized offices, restaurants, or retail stores, with limited space for multiple outdoor units. They balance efficiency and convenience, allowing different areas to be heated or cooled independently based on occupancy or preference.

Did you know multi-splits are more energy-efficient than having multiple single splits?

Potential Limitations

The installation and technology of a multi-split system can be more complex and, therefore, expensive. Thoughtful planning is required to ensure the outdoor unit is powerful enough to support all connected indoor units and the system is optimally configured for the specific layout and needs of the building.

3) VRF/VRV Systems

Description and How It Works

Variable Refrigerant Flow (VRF) or Variable Refrigerant Volume (VRV) systems consist of one or more outdoor units connected to multiple indoor units via a network of refrigerant lines. They’re controlled by a sophisticated system that varies the flow based on the demand of the indoor units.

In VRF/VRV HVAC systems, each indoor unit can be controlled independently, allowing for precise temperature control in different zones or rooms. This is facilitated by advanced inverter technology and sophisticated electronics.


By operating at varying speeds, these systems consume only the amount of energy needed at any given time, significantly reducing energy consumption. Energy efficiency means lower operational costs and a smaller carbon footprint, making these systems a more environmentally friendly choice.

Additional benefits:

  • Flexibility in terms of installation and design.
  • Adaptability for large, multi-zoned spaces like hotels, large offices, and mixed-use buildings.
  • Quiet operations, improving the comfort of the indoor environment.

Potential Limitations

Due to the complexity of the technology and the need for carefully planned and specialised installation, they have the highest cost of the 3 HVAC options.

These specialised installations will also require expertise for troubleshooting and repair, potentially leading to higher maintenance costs.

The Lifespan of Commercial HVAC Systems

The lifespan of HVAC systems will vary, dependent on the technology, brands, maintenance, usage, and more. But here are some rough lifespans to give you a good idea:

Single-split systems typically have a lifespan of around 10 to 15 years. Factors that can affect this include the quality of the unit, the climate in which it operates, and how well it is maintained.

Multi-Split Systems generally last between 10 to 15 years. However, regular maintenance can extend their lifespan, especially since these systems often serve larger spaces and endure more extensive use.

VRF/VRV Systems are known for their durability and can often last upwards of 15 to 20 years. The advanced technology and higher build quality contribute to their longer lifespan. Regular maintenance is essential to ensure they continue to operate efficiently over time.

What is the difference between domestic and commercial refrigeration?

What is the Difference Between
Domestic & Commercial Refrigeration?

One of the questions we get asked by hospitality professionals who are stepping out into their own business is whether they need to invest in commercial refrigeration straight away. After all, if you are opening a small café or bar, chances are you are only servicing a small number of people at a time, and perhaps don’t see the value in investing in a commercial refrigerator. But there are some significant differences between domestic and commercial units – and having the right kind of unit can end up saving you money on running costs.

Domestic Fridges

Domestic fridges are much quieter than commercial fridges and chill products efficiently without consuming a lot of power. However, they are not designed to cope with products being continuously taken out or replaced and this is the main reason a domestic refrigeration unit is not suitable for commercial businesses. One of the other drawbacks to domestic refrigeration units is that they tend to come only in a small range of standard sizes. And finally, domestic units generally come with freezers attached, whereas commercial units typically do not.

Commercial Fridges

Commercial fridges come in a huge range of shapes and sizes to suit whatever retail space you are looking at. From upright display models to smaller units designed to fit under a bar or kitchen benches and fridges which are designed for transportation of produce or liquids, you can select the shape and type of fridge specific to your requirements.

Commercial fridges and freezers have been designed specifically so that they can remain cold despite being continuously in use. They have larger compressors, condensers and fans which work to continuously distribute chilled air inside the unit and remove excess heat from the coil. All this power comes at the cost of a noisier unit than what you would experience with a domestic refrigeration unit – but means that your products will stay chilled regardless of how often the unit is opened in an hour.

Looking After Your Commercial Fridge or Freezer

It is even more important to regularly service a commercial unit thanks to the supercharged motherboard, compressors, fans and insulation. Because your unit is working hard virtually all the time, any stress (such as very hot days in summer) can have an impact if your fridge or freezer is not taken care of.

Most people don’t realise that the refrigerants in air-conditioners and refrigerators can be extremely harmful. However not only can chlorofluorocarbons (CFCs) and greenhouse gases damage the ozone layer, but freon can also cause poisoning in humans if inhaled.

That’s why it is crucial to choose a licensed professional to install and service any cooling system. And to make sure your technician has a current ARC license before they perform work in your home or business.

What is the ARC?

The Australian Refrigeration Council (ARC) is an independent body appointed by the Minister for Environment and Heritage to administer the national refrigeration and air conditioning permit scheme. The ARC grants Refrigerant Trading Authorisations and Refrigerant Handling Licenses to approved businesses and individuals who acquire, posses, handle or dispose of fluorocarbon refrigerants. Their aim is to ensure that ozone depleting substances (ODS) and synthetic greenhouse gases (SGG) are handled in such a way as not to damage the environment.

How can I check an ARC License?

The best way to check if a technician holds a current ARC Refrigerant Handling License is to go to the ARC website and do a license check. You just need to enter the technician’s license number and surname and the search function will tell you if their permit is valid.

What is the ARC Tick?

The ARC tick is given to businesses and individuals who are authorised to install, service and repair fridges, freezers and air conditioners, in your home, office or car. The tick identifies the license holder as complying with Australian law regarding safe handling of fluorocarbon refrigerants.

How do refrigerants affect humans?

Freon is the trademark name for the liquid refrigerant used in refrigerators and air-conditioners. Without regular servicing, leaks can develop, making your cooling system less effective and potentially exposing you and your family to the escaping gas. Although mild exposure is generally harmless, poisoning can occur in confined spaces or through misuse. Symptoms include migraines, nausea, and fainting.

How do refrigerants affect the environment?

Gases contained in refrigerants cause ozone depletion and contribute to global warming. Just one kilogram of the most common has, R410a, has the same global warming impact as two tonnes of carbon dioxide!! This is the equivalent to driving a four-cylinder car for 6 months.

Why is it important to use a licensed technician?

Because the refrigerants used in air-conditioners and refrigerators can be extremely harmful to the environment and to humans, it is important to ensure you book a professional to handle your cooling systems. Licensed technicians have the training and skills to correctly handle refrigerants and minimise the risk of emissions.

How often should I get my fridge, freezer or air-conditioner serviced?

Most of our customers don’t even think about getting their refrigerator, freezer or air-conditioning unit looked at until a problem occurs. But just like your car, regular servicing will prolong the life of your cooling unit and help you to avoid expensive breakages. At Precision Air-Conditioning & Refrigeration we recommend you have a technician check your units at least once a year.

Get in touch with one of our friendly team today and we’ll send an ARC approved technician to assess your fridge, freezer or air-conditioning and ensure it is functioning efficiently and safely.

How to heat your home this winter using reverse cycle air-conditioning

How to heat your home this winter using reverse cycle air conditioning

It’s that time of year again in Melbourne! The temperatures have started to head south, and our winter clothes are making an appearance once more. This is the is the perfect time of year to start thinking about how you will heat your home this winter!

While there are many different options available, one of the easiest and most affordable options around is a Reverse Cycle Air Conditioning Unit. So, what makes this such a great option?


The beauty of a reverse cycle system is that you are getting two climate control systems in one. For cooling, your unit absorbs heat from inside your home and dissipates it outside. This energy efficient method means that Reverse Cycle cooling can work in temperatures of up to 45ºc – perfect for our intense Australian summers.

Then in winter, the system works in the opposite way, by absorbing heat from outside air and releasing it indoors. And it doesn’t need to be warm outside for this to work – in fact, a good reverse cycle air-conditioner can work in temperatures as low as minus 15ºc.


For most of our clients, one of the most important factors in selecting a heating and cooling system is the effect the new system will have on their power bills. And that is why the reverse cycle system is so popular. They are incredibly efficient in terms of energy use, heating and cooling even in the most extreme conditions. In fact, reverse-cycle air conditioning is 300–600% efficient, which means that it can take one unit of electrical energy and turn it into 3 to 6 times as much heating or cooling energy.

Talk to our expert technicians about the different energy ratings for reverse cycle air conditioning units. While it might cost you a little more initially to opt for a higher rated system, you can save money over time with a more efficient unit.


Most modern reverse cycle air conditioning units now have invertor technology which helps the system perform even more efficiently. Invertor technology allows the unit to adjust power to reach the desired temperature faster and then steadily maintain it for uninterrupted and more energy efficient climate control.


Some reverse cycle split systems can even purify the air inside your home, using a built-in filter to trap particles and in some cases, even reduce odours and neutralise bacteria and viruses. For families with asthma sufferers or other allergies, this can be a huge advantage to choosing a split system. Talk to our expert technicians to find out which model will best meet your family’s needs.


Thanks to their incredible efficiency, reverse cycle air conditioners produce around one thirds the greenhouse gas emissions of a standard electric heater.  And for some of the highest rated models, this drops to only around one fifth of a standard electric heater’s emissions. So not only are you saving money by using less energy. You’re also reducing your carbon footprint and heating your home in a more sustainable way.


Compared to ducted heating, installing a reverse cycle air conditioning unit is quite inexpensive and very quick. Precision Air Conditioning & Refrigeration technicians all hold the following certifications which are essential for the safe installation of your split system.

  • ARC Tick – authorises businesses and individuals to install, service and repair air-conditioners
  • Energy Safe Victoria – certifies that your technician is legally allowed to work with electricity and gas
  • VBA – your technician must be a registered plumber with the Victorian Building Authority.

With a 36-month warranty on all installations, you can rest easy knowing your air-conditioning will be installed to the highest standard.
