What To Choose? Ducted Air Conditioners vs Split Air Conditioner 

So, you’re after an air conditioner but are stuck on which type to purchase – a ducted reverse cycle system or a high wall split system?

Both are effective at cooling a space, but the way that they do this differs dramatically. Your choice will often depend on a number of factors such as the space that you are wanting to cool, your budget, whether your home can accommodate the system, and much more.

Ducted Air Conditioning

Ducted reverse cycle air conditioners work just as the name suggests – through a series of ducts. These are hidden within the roof space and out of sight, making it the more attractive choice. They contain a central unit, known as the fan-coil unit. Ducts then branch off of this fan-coil unit and run to different rooms/zones within your home. The air is expelled from the vents in your ceiling, which are the only visible parts of the system.

There are many pros for ducted air conditioning in comparison to split systems, with one of the biggest being that you can easily and efficiently heat or cool your whole home at the touch of a button. Controlled by a thermostat, ducted systems are much better at keeping a consistent temperature throughout your whole home, but the option to have your system zoned means that you can individually control the amount of conditioned air to each room. There are two ways that you can do this; with a simple on/off switch, or a variable air volume controller which you can increase or decrease the amount of airflow to suit your requirements. The last option also allows for better air balancing throughout your system. The entire system is completely hidden within the roof cavity of your home (besides the vents in your ceilings), making it the more attractive option over split systems. Ducted systems are often a lot quieter than their counterparts, with the only noise being a quiet fan noise from the outdoor unit, and gentle passing of air through the central filtration grille.

Despite the extensive list of pros, ducted air conditioning systems also have their limitations. Ducted systems are the more expensive option to purchase and have installed. As the system is installed within your roof, technicians will need to spend a large amount of time and effort, cutting into your ceiling and this can often add to the cost. Having a ducted system installed is best done during the building or renovation of your home (but not limited to), and they can often be restricted to which homes they can be installed in. Apartments and dwellings with limited roof space often may not be able to have ducted systems installed due to this reason, and already built two-storey homes need a large amount of extra consideration and planning. They are also not the best option if you only spend an extensive amount of time in only a small area of your home.

Split System Air Conditioning

Split system air conditioners are the most ideal solution for single room heating and cooling. They are made up of two components – an indoor unit (head unit) and an outdoor unit (compressor). The indoor unit moves the cool air around the room, while the outdoor unit dissipates the heat from the cooled area (heat exchange).

Split system air conditioners are the more cost-effective choice to purchase and have installed. Due to the fact that you are not purchasing an entire system of ductwork and vents, the costs can be minimal in comparison to ducted systems. A considerably less amount of time is needed for technicians to install them, and there is minimal modification required to your home. If budget is a restraining factor, more split systems can be added to your home if you require later on, or as your budget allows. Due to the fact that split systems only heat or cool one room or space of your home, they have lower energy demands and therefore are quite cost-effective to run.

However, there are also cons involved with having a split system installed within your home. The heating or cooling capacity is limited with splits, and therefore may not be a possible option for your space. While they are the cheaper option singularly, if you need multiple units within your home, the costs can add up. The bulkiness of both the indoor unit and the outdoor unit, and the inability to hide them can often become an eyesore and stand out on your wall. So if you are looking for a neat and tidy option that is easily concealed, then a split system is not your choice.

So which option is best for me?

Each of these systems essentially performs the same job, but personal preferences and limitations can restrict which one is best for you. It is important to take into account each of the pros and cons provided so that your system benefits you for years to come.

Factors to think of when deciding include:

  • What maintenance/upkeep is included – A ducted system will require yearly services by a professional, while a split system will require more regular cleaning that can be completed by the homeowner, and professional servicing less frequently.
  • How much you want to spend – A ducted system will cost more to purchase and have installed upfront but the options to zone your system means that their running costs can be reduced. While a singular split system will cost less upfront, should you need to add more in the future, the costs can add up.
  • What area you are looking to cool – Do you want to cool your entire home or just one room? Should you only need one room cooled, is important to think about whether you will be wanting to cool more in the future.
  • Aesthetics – The way the system will look is also something to think about. While split systems stand-out on both an indoor and outdoor wall, they are becoming much more visually appealing.

Signs That Your Air Conditioner Needs A Service

5 Signs That Your Air Conditioner Needs Attention

Our hot South Australian climate means that we rely a lot on our air conditioners in our homes and businesses to keep us cool and comfortable. But air conditioners are a lot like cars – they need regular servicing and maintenance to run at their most efficient.

Regular servicing should be carried out yearly, but every now and then small issues may arise which can indicate a need for a technician to thoroughly inspect it.

Here are some signs that you may need to book a service:

1. Your System Isn’t Cooling

If your system isn’t doing what it is designed to do, then it needs an inspection. A unit that isn’t blowing out cold air may indicate an issue with its compressor, mechanical failure within the system or that the system has lost its refrigerant charge. Neither cause is impossible to fix, but you will need to have it seen to if you plan on using your system to stay cool throughout summer.

2. Reduced Airflow

If air is not circulating through your rooms as strongly, then your unit’s fitler may be clogged, it’s ductwork may be squashed or damaged or its zone motors may have malfunctioned. It’s important to clean your filters regularly as mentioned here, to avoid overworking your system. But damaged ductwork or zone motor failure needs to be left for a technician to inspect and attend to during a service.

Regularly using your system when it is struggling to maintain airflow can severely overwork your system’s compressor and can easily cause extra damage.

3. Strange Smells or Noises

During operation, an air conditioner should be relatively silent. It should also not be emitting any strange smells after being turned on. If your unit is doing one, or both of these things, then a service is needed immediately to get to the bottom of it.

One role of an air conditioner is to filter dust and small debris from the air, as well as dehumidifying it. A musty smell may indicate that there is dust entering your ductwork or a build-up of foreign material on your indoor coil, which can be harmful to your health if you breathe it in, and potentially dangerous to asthmatics.

A burning smell though may indicate something far more serious such as overheating of internal components, loose wire connections, mechanical issues, etc. If your system is giving off a burning smell it is best to turn it off and discontinue use until you can schedule a time for a technician to inspect it.

Depending on what noise you are hearing coming from your unit, there may be a number of issues it could be:

Humming or Rattling

An air conditioner naturally hums due to the mechanics involved with it. But if a light hum or whir turns into a much more sinister noise, often followed by a rattling, then it may indicate that a fan is loose, there is debris caught in your unit, there are issues with your ductwork or more.

Grinding

Any grinding noise coming from your unit during operation is cause for concern and needs immediate attention from a professional. This noise may indicate serious mechanical issues within your system and operation should cease immediately.

Hissing

A hissing sound can either indicate a minor issue such as a water leak, or a major issue such as a refrigerant leak. If you are untrained, distinguishing between the two can be difficult, so it is best to have a professional take a look at it.

Any other noises coming from your system during operation should also be investigated by a professional. It is better to be on the safe side and have a clean, healthy running unit, than one that may fall apart at the wrong time of the year, or worse yet, create an unsafe situation.

4. Leaks

As mentioned, if your unit is leaking it can either be a minor issue that results in a quick fix or a major issue that can have an unsuspected effect on your home. If you do notice a leak, it is important to cease the systems operation and contact your installer/service mechanic. They will ask a number of questions that can help them distinguish what the leak might be and just how serious it is. Water leaking from your unit isn’t a large issue and is generally a quick fix, however a refrigerant leak is potentially dangerous. Don’t try to distinguish between the two yourself. Call a professional and have them assess the situation.

5. High Energy Bills

If your energy bills seem higher than normal but you are not using your system any differently, then there may be an underlying reason why. When you don’t maintain your air conditioner regularly, it will become less energy efficient and your energy bills will start to rise. This may be due to issues with your ductwork, you may not be using your system correctly, or maybe your unit is reaching the end of its life.

If you are finding that one, or a number of these issues are occuring during operation of your system, the best thing to do is schedule a technician to do a thorough inspection and service on it to find the leading causes.

As summer is fast approaching, the smartest thing to do is to have a professional from Green Efficient Living come and do a pre-summer service on your unit to ensure that it is in prime working condition before constant use during the upcoming hot weather.

Why Should You Have Your Air Conditioner Serviced?

Why Should You Have Your Air Conditioner Serviced?

Having your air conditioner serviced before the hot weather hits is smart for two reasons. Not only does it mean that you will be prepared for when the temperature starts to rise, but it also means that you will beat the rush of people trying to get theirs serviced during summer.

What Is Done During A Service?

During a scheduled routine service, a Green Efficient Living technician will complete a number of checks on the outdoor unit and indoor unit to ensure its compliance and that it is operating as it should.

The first thing that our technicians do will ask you whether or not your system is functioning properly. Have you heard any noises lately? Has it been playing up or not running as it normally would? Etc.

The return air will be then taken out and checked over, during which time our technicians run your system to inspect the outdoor unit. They will get the pressure readings, check electrical voltages and currents and ensure that there is no debris on the rear coilers of the unit.

After the service of the outdoor unit, they will then get into your roof to inspect that all electrical terminals are still tight, that the ductwork does not have any imperfections such as rips and that the main condensate drain isn’t blocked. During this time they will also inspect all zones by turning them on and off to ensure that they are all opening and closing as they should.

Can You Service Your Own Air Conditioner?

There are basic maintenance jobs that you can do yourself as the homeowner, such as cleaning the filters and ensuring that the outdoor unit stays unrestricted (see our post on that here). But when it comes to a complete annual service of your unit before using it again, this MUST be left entirely to the professionals. The smallest of attempts at servicing your own air conditioner can lead to serious unit damage or even electrocution!

Why Should You Have Your Air Conditioner Serviced?

The easiest way to understand exactly why you need to regularly service your air conditioner is for the same reason that you regularly service your car. You do not drive your car unserviced until it breaks down beyond repair and you are forced to buy a new one. Instead, you service it regularly to AVOID any serious breakdowns – an air conditioner is much the same.

There are many reasons why having your air conditioner professionally serviced is important:

1. It improves energy efficiency and saves you money on your electricity bills

Without periodic maintenance, your air conditioner will find it hard to run in prime condition. When this happens, it has to work a lot harder and consume more energy which in turn costs you more on your electricity bills! Avoid paying more by having a professional complete a service on your air conditioner to ensure that it is running as efficiently as possible.

2. It improves air quality

When your air conditioner isn’t working efficiently, it cannot properly filter the air is distributed into your home. An air conditioner that is running in perfect conditioner successfully filters out pollutants, pollen, dust and allergens, meaning the air that you and your family are breathing is cleaner and safer.

3. It extends your unit’s lifespan

Regular servicing and maintenance will extend the lifespan of your unit for all of the reasons mentioned above. It faults are left undetected, they can cause serious issues for your system in the future. These issues may result in costly repairs or even a unit replacement! However, by servicing it regularly you are increasing your system’s lifespan and keeping it running in perfect working order for many more years to come.

The professionals at Green Efficient Living recommend having your unit serviced annually, even if it is not showing any signs of faults or issues. To book your annual service, call us today on (08) 8297 3422.

Winter Is Here

If you live in Adelaide, you would surely understand just how drastically the temperature can change between summer and winter. One moment you are sitting in a puddle of your own sweat and within a matter of weeks, you are sitting in that same spot, with four layers of clothing on, clutching your coffee close to you.

Well, in case you haven’t noticed, winter is here and we think that it is time that you understand how to best care for and use your reverse cycle air conditioner during the colder weather to maximise your energy efficiency and save on your bills (you will thank us later).

Hitachi Wall Split Reverse Cycle Air ConditionerWhat Is Reverse Cycle Air Conditioning?

The name suggests it all. A reverse cycle air conditioner is one that can both cool your home in summer and keep you warm during winter.

A refrigerant is passed through an external coil, absorbing heat from the outside air. This refrigerant is then pumped through a compressor, into a fan coil unit inside the home, which then releases warm air into your room. When in heating mode, the unit works in the opposite or reverse way to when it is cooling.

Note: It absolutely does not have to be warm outside for this process to be successful. Reverse cycle air conditioners can perform this function in even the lowest of temperatures.

Benefits Of Reverse Cycle Air Conditioners

The first and in our opinion, the greatest benefit of reverse cycle air conditioners is that they are extremely efficient when it comes to their energy use and their cost over time. Most portable heaters or gas heaters may be cheaper to buy outright, but their energy usage is much higher than that of a reverse cycle system and therefore will cost you much more over time to run.

Another benefit is when purchasing a reverse cycle air conditioner, you are purchasing two systems in one and avoiding having to purchase both a cooling system and a heating system, thereby saving you money.

Reverse cycle air conditioners also help to purify the air during operation by trapping airborne particles. Some systems may also rid the air of odours and remove bacteria and viruses, which is especially handy in the homes of allergy sufferers and people with asthma.

How To Prepare Your System For Winter

If you do already have a reverse cycle system installed in your home, there are a few things that you can do before the cold weather really sets in.

Clean Your Filters 

We have already written a blog on the importance of making sure that your filters are clean (read here), but we can’t stress enough just how damaging blocked filters can be. Blocked or dirty filters are often the first issue that we look for when on a service call, due to the fact that…

Adjust Your Thermostat 

Most people think that turning their heater up to 26 degrees in winter will warm the room up faster and keep them warmer for longer. All this will do is result in your system working harder and your energy bills increasing. During winter, have your system set to 18-22 degrees. Your room will still warm up just as fast and you will still feel just as warm, you just won’t be paying the extra on your energy bills or shortening the life of your system. It has been estimated that increasing the temperature on your air conditioner by just one degree can increase your costs by a large ten per cent!

Have It Serviced 

One very important point to remember is to have your system professionally serviced before a long summer or winter of using it. When a technician services your system, they make sure that everything is working as it should be and that your system is still providing the most energy efficient service that it can for your needs.

Conclusion

Using your reverse cycle air conditioner is no different in winter than it is in summer. Just remember to keep the temperature down, you will still stay warm, and to make sure your filters are clean. If you haven’t had your system serviced yet, Green Efficient Living have a special offer for you! You can have your Ducted Reverse Cycle system serviced from a low $200 ex GST, or a High Wall Split from $170 ex GST. Our offer ends VERY soon, so give us a call today to make sure that your system isn’t costing you more than it should this winter!
