Installing Air Conditioning – Things to Consider

Installing Air Conditioning – Things to Consider

Installing air conditioning is the solution to effective climate control in your home or business.  You can choose the perfect unit to keep things cool in the summer and warm in the winter.  A variety of factors must be considered when selecting and installing the best air conditioning unit suited to your space.

Things to Consider When Installing Air Conditioning

For the average person, you may not know very much about installing air conditioning units.  It can be an overwhelming decision not knowing what type and kW to go for to ensure your home is cooled and heated efficiently.  Air conditioning specialists are happy to discuss these options with you and help you consider other factors. These factors include the unit’s refrigerant, ductwork and air quality adjustment settings.

Do You have Ductwork?

The first thing to consider when installing air conditioning is what type you might need.  Ask yourself if your home or business has existing ductwork.  If so, you might opt to go for a ducted system that can reach every room.

Ductless Systems

Another popular option is ductless systems, which still allow you plenty of control over the way you cool or heat your home.  Consider if you want a dedicated air-conditioning unit, as many modern models have reversible functions and can be used to heat your home as well.  This will keep the temperature perfect all year around.

What Sized Air Conditioning Unit Do You Need?

Whatever type of system you go for, consider the size or kW.  This doesn’t refer to how much the unit weighs, but rather how much air the system is capable of moving.  The kW of the unit determines its output capacity and is an important factor to ascertain the correct sizing of your new unit.

Don’t Go Too Small

When installing air conditioning and choosing the size and output capacity, consider efficiency and longevity.  Remember that a low output can mean the unit is constantly running.  This uses up a lot of energy and is prone to failure in the hottest months of the year when you need it most.

Don’t Go Too Big

Conversely, choosing the biggest unit you can find doesn’t necessarily mean it will be the most efficient option to cool your home.  Short cycling is when the unit stops and starts often and this is a big energy waster.  The key is to find the perfect size in the middle – a unit that cools your home without running constantly but also isn’t unnecessarily large.


The size of the unit is not the only factor affecting its efficiency.  The rating system used to measure how effectively a system works is known as the Energy Efficiency Rating (EER) or Coefficient Of Performance (COP). When choosing a new air conditioning unit, look for a minimum rating of 3 for larger systems and 5 for smaller systems.  A more efficient rating will be kinder to the environment, while powerfully controlling the climate of your home.  An efficient unit ensures that the minimum amount of energy is used, working smarter and not harder.

What About Refrigerant?

Consider if the air conditioning unit uses Freon (R22), a common refrigerant that can periodically require replacing.  R22 refrigerant is particularly unkind to the environment and is being phased out in Australia.  Look for R410a refrigerant or the latest and most efficient refrigerant, which is R32.  A technician will be able to give you qualified advice on the different types of refrigerants and systems. This will be specific to the unit you choose and the size of your home.


Once you find the right sized system for your home, you’ll need to consider the different rated ductwork available.  Several different ratings exist for ductwork and it’s important to choose the right one for your installation.  It’s important to choose a system with efficient ductwork, as ductwork that leaks or is of insufficient insulation rating will not cool or heat your home efficiently and will use up excess energy.  Though ductwork can be fixed down the line if it’s necessary, choosing a well made configured system in the first place will save you time and money.

Air Quality

Find out if installing air conditioning includes a system that purifies and filters the air before it circulates back into your home.  Air quality is imperative to health and well-being and this can be a factor that homeowners forget to consider when investing in a new unit.


If you don’t want to waste time every day setting and adjusting the thermostat, you can choose a programmable option.  This allows you to preset the temperature to ensure your comfort and will actually save you money.  Constantly adjusting the unit’s thermostat is not only time consuming, but it’s counterproductive to the machine’s efficiency as well.

Environmentally Friendly

An upgraded air conditioning system will cool or heat your home more effectively and efficiently than an outdated system.  It will use less energy, which is better for both the environment and for your electricity bills.  Certain types of coolant have higher environment-friendly ratings as well and you can ask your technician about this.


When installing air conditioning the unit must be installed correctly to ensure it continues to run at peak efficiency.  Routine maintenance such as inspections and filter changes will keep the system working well.  This helps prevent any issues from developing down the line.  This preventative maintenance allows technicians to fix potential issues before they occur.


Installing air conditioning with the most up-to-date model is not the best solution in every scenario.  Some units can benefit by routine upgrades, which will improve the efficiency of the system.  However, a new system will likely last longer and work more effectively, instead of repairing an older outdated model.


Consider the wide variety of specifications installing air conditioning might have.  You might still be unsure which option will be most effective and efficient for your home.  Air conditioning specialists can help you make this decision and ensure you get the most out of your new system.
