Why are split systems so popular for rental properties?

 

Why are split systems so popular for residential properties?

When we look at answering this question, we are not evaluating the physical property itself, rather the landlord vs tenant arrangement. Obviously, the physical aspect of the property comes into play, however, it is a case-by-case basis in regard to what air conditioning system is going to suit one property over another. For this blog we will focus on stand-alone investment rental properties, as opposed to apartments or unit complexes. The types of air conditioning systems available, and most popular, in the residential market are wall mounted split systems, multi split systems (multiple indoor units and one outdoor unit), ducted air conditioning systems.

Wall mounted split system air conditioners have seen a surge in popularity in recent years and are now an extremely popular climate control option when investing in rental properties in Queensland and NSW. Nevertheless, as you can expect when looking at an investment rental property it mostly all comes down to the numbers. What numbers you may ask? Firstly, there is the initial outlay, or upfront cost, of the air conditioning equipment and installation. Secondly, being an investment rental property the landlord needs to factor in the time to pay back that upfront cost. Thirdly, ongoing electricity and servicing, or maintenance, costs. This will depend on the rental agreement the landlord has with the tenant and what the inclusions are and, who pays the electricity bills.

What is the cheapest air conditioning option?

The initial cost outlay for a wall mounted split system and installation is lower than a traditional central ducted air conditioning system. This may change when you start to look at multiple wall mounted split systems, or a multi split air conditioning system at the property. The cost outlay is a lot lower as usually there is a lot less involved with the installation itself, and the wall mounted split air conditioner cost is more minimal in comparison to a larger ducted air conditioning system. However, when looking at the ‘big picture’, the cheapest outlay might not be the best option in the long run for landlord.

How long will it take me to get return on my air conditioning investment?

There are so many variables to answering this question. If you look at the initial outlay alone, a wall mounted split system can cost anywhere between $1500 – $4000 to have installed. You may be able to earn an extra $30-$50 per week in rental income as your property is now more attractive having air conditioning installed, and this may enable you to pay off your investment in as little a 2.5-3 years. Not to mention the landlord may be eligible for tax benefits on this investment, and the capital value increase. Mind you there are other factors to consider that effect the payback rate such as securing long term tenants and minimising your vacancy rates. All these variables need to be considered.

Who benefits from an energy efficient air conditioning system?

Generally, it is the tenant that pays the electricity. From the landlord’s perspective this removes the financial incentive to outlay more initial cost to invest in the most efficient air conditioning system, or system with the most bells and whistles. If, however, the arrangement is that the landlord pays the electricity, then it might be more in their interest to have a more energy efficient air conditioning system installed.

Obviously, energy efficient air conditioning systems will run better and save you money in operating costs, and they are also better for the environment. Daikin, for example, invests heavily in research and development to continuously improve the energy efficiency of their products. Efficient, computer-designed air control surfaces, proprietary inverter technology and ‘intelligent eye’ sensors are just some of the innovations that make Daikin air conditioners amongst the most energy efficient on the market.

What are the air conditioning maintenance costs?

Finally, the last major factor to consider is ongoing preventative maintenance and breakdown and repair costs of the air conditioning system/s once installed. Maintaining your new investment by servicing it on a regular basis (we recommend yearly at a minimum) is highly recommended, after all, you want to get the maximum lifespan from your investment. Regular preventative maintenance not only assists in the prevention of unexpected, unfavourably timed and costly breakdowns, it will help to prolong the life and efficiency of your air conditioning system, whilst saving you money in unwanted electricity costs.

Servicing costs are usually per system, so if you were to have one wall mounted split system in your investment property this would be one set cost (well, that is how we charge our fees). Most air conditioning companies will then charge you a reduced fee for every other wall mounted split system you have to be serviced at the same time. Again, this is all quoted before attending site to service your systems, so there are no surprise monetary costs. The same operation with a ducted system, however, most residential properties only have one ducted system and so therefore only one fee every year for servicing. Depending on how many split systems you have in the property, it may be more expensive in maintenance costs to service yearly.

In summary, it will generally depend on the personal circumstances and investment strategy of the landlord as to the type of air conditioning system they choose to install. Wall mounted split systems are a great option as they are more cost effective to install and because you can control the operations per room, the electricity costs can be quite efficient. If the landlord is planning in investing for the long term, having an air-conditioned rental is appealing to secure a good long-term tenant and maintain low vacancy rates (oh, and to also keep the tenant appreciative in the hot and humid summers of Brisbane, Sunshine Coast and the Gold Coast).

How to Know If Your Ducted System Needs Servicing

 

Ducted air conditioning systems are efficient, cost-effective and one of the wisest HVAC options you can choose to have installed in a new home or as an upgrade to your existing premises. By allowing you to independently control the temperature of different zones within the house they afford you maximum comfort at minimum cost while helping safeguard your family’s health.

Like any mechanical or electrical system, ducted air conditioners need regular maintenance to keep operating at their best. Ideally you would have your ducted air conditioning system inspected and serviced by a professional every six months to assure your comfortable enjoyment and avoid major repairs in the future. Unfortunately, air conditioners are one of those items that many people only think about once a problem arises.

This is a recipe for heartache as bad things never happen at good times. The truth is that if you have a ducted air conditioning system you need to have it serviced regularly to avoid major issues. Ducted air conditioners are complex systems that are subject to some unique complications if not properly maintained.

To help you stay cool and comfortable when the summer heat comes to Queensland and New South Wales, here are some of the problems a ducted system can develop if not properly maintained.

Leaking ductwork

The ductwork in most residential appliances is made from a flexible or rubber material. As your air conditioner cycles airflow the natural heating and cooling of the ductwork causes it to move and flex ever so slightly. Over time, this movement can cause tiny tears to develop, fittings to loosen and allow air to escape into or out of the system.

This will reduce the efficiency of your system causing it to run longer and more often to maintain the comfort of your home. At a minimum, this will make it more expensive to operate and shorten the lifespan of your unit. It can however cause more serious problems.

Openings in your ductwork can cause condensation to form and lead to water damage or the formation of mould and mildew. This along with the fact that unfiltered air can be drawn into the system could have health ramifications.

In many cases, minor damage to ductwork can be repaired. Past a certain point, it will become necessary to replace the ductwork. An expense that is easily avoided with routine maintenance.

Dirty ducts

In a properly functioning air conditioning system, the air is filtered as it passes through the unit. If leaks develop or filters are not properly cleaned or replaced when needed, ducts can be contaminated with dirt, dust, dander, pollen, mould and other allergens affecting the air quality within your home.

For people with respiratory issues like asthma, or eye and nasal allergies this can become a major concern if left unchecked. For homes with pets or in humid environments such as coastal areas in northern New South Wales and Queensland these issues can develop very quickly.

Unbalanced airflow

A correctly designed, installed and functioning ducted air conditioning system will have a balanced supply/return flow and maintain a neutral air pressure within the house. If out of balance, whether from a design deficiency or unmaintained and damaged ductwork, it will place a greater strain on the unit causing unnecessary wear and tear and excessive power use.

Insufficient insulation

Unlike other HVAC systems where the entire unit is in fairly close proximity, a ducted system relies on its ductwork to carry air from a centralised location. Depending on the home this can entail considerable distances and a certain amount of heat exchange is to be expected.

To minimise this loss, ductwork should be properly insulated. The insulation can be easily damaged from moister or vermin and can simply come loose with time and should be inspected and repaired or replaced regularly.

Malfunctioning zoning gates

If your home or building has a zoned system then it has gates that open and close to regulate the flow of air to each area. If these gates become stuck or malfunction the system will not be able to properly regulate itself. Highly sensitive, these gates should only be serviced by properly trained technicians.

Clogged condensation drain

Condensation is a natural part of any air conditioner’s operation. Dehumidifying the air is one of the primary functions an AC unit performs. Every unit has a drain line or hole to allow the excess water to be channelled safely away. If this drain becomes clogged it can cause negative pressure, musty odours, clogged filters, and in extreme cases severe water damage due to overflowing or water being sent through the ductwork into the house.

Dirty Coils

Air conditioners have two coils: a condenser coil that dissipate the heat that the refrigerant in your system has absorbed, and the evaporator coil that heats the refrigerant from the air as it passes over the coil. Over time these coils can become dirty and clogged inhibiting their ability to exchange heat and your ducted cooling system’s ability to deliver peak performance.

What Air Conditioning System is best for me?

There are only so many times in a summer that it’s appropriate to run around the backyard sprinkler in your underwear before the neighbours start to complain, not to mention the water bill! If the Australian sun has finally made you go bonkers, then it might be time to invest in an air conditioner. Which one is the best to suit your needs? We’ve broken it down for you..

Home air conditioning systems come in several types, ranging from large central systems driven by outdoor compressors to small plug-in units that stand on the floor or mount in a window. No matter what form they take, air conditioning systems have similar working components, including a refrigerant, a compressor, a condenser, an expansion valve, and an evaporator coil. All of these work together to transfer heat and moisture from the inside of your home to the outside.

Split Air Conditioners

The split system is commonly found in homes as well as hotels and other multi-unit buildings. It has become an increasingly popular option for homes that are not served by a forced-air HVAC system, such as those with hot-water heating or electric heating. Most split air conditioners also offer heating as well as cooling functions.

The split system breaks the air conditioning system into two packages: The condensing unit is located on the building’s exterior and includes the compressor, condenser, and condenser fan. The evaporative unit is located on the interior and handles the air cooling and distribution. This is usually a rectangular box unit mounted high on an interior wall and contains a circulation fan, expansion valve, and evaporator coil. Refrigerant tubing passes through the wall between the condensing and evaporative units.

Multi Split Air Conditioning

As above, the information is the same, the difference with multi split systems are that they can heat or cool multiple rooms using only one outdoor unit connected to multiple indoor units. Each indoor unit can also be individually controlled, scheduled and set to the desired room temperature.

Ducted Air Conditioning 

A ducted air conditioning system is the largest type of conventional air conditioner.  Unlike a split system, a ducted system provides discreet air conditioned comfort. It can be installed in a new home or tailored to suit an existing one, and once installed, only the controller, the return air and discharge grilles are visible inside your home.

Ducted air conditioners are typically the most effective type of air conditioner for cooling entire homes. They work primarily through a series of ducts to keep you cool. Ducted air conditioning has an internal fan coil unit installed in the roof space of the home. From this central location, a series of ducts run from it and into as many rooms in the house as the owner desires. From these ducts, this allows you to cool or heat each room individually – called zoning. This is done so by the thermostat on the wall, allowing you to select the temperature and other settings.

When installing a new ducted system, the primary consideration is making sure the system is sized appropriately for your home. If a system is too large, it will not perform well and will not adequately dehumidify the interior air. If it’s too small, it will not cool adequately. Proper maintenance of a central air conditioning system is also very important.

VRV  Air Conditioning

VRV stands for Variable Refrigerant Volume. A VRV system is still the only system that continuously adjusts the refrigerant volume within the system to match exactly the heating or cooling requirement in each area, for optimum comfort and maximum energy efficiency. VRV air conditioning systems are basically large multi-split systems where a number of indoor units are connected to the outdoor unit. These VRV air conditioning systems are generally used for larger applications where the alternative might be a central chilled water system or central ducted system. Against these other types of system VRV air conditioning would generally be comparable in capital cost but would quicker to install and more energy efficient to run.

Early in the morning, no matter what the time of year, the north facing rooms of a building are likely to be quite chilly, whilst those on the south side will feel a bit warmer. As the sun rises, the temperature inside the building will rise more quickly on the elevations facing the sun. Consequently, those rooms which do not benefit from this solar gain continue to maintain a requirement for heating at the same time that those south facing rooms need cooling.
With conventional air conditioning systems the occupiers of the building would be unable to enjoy simultaneous heating and cooling.
With VRF/VRV technology, however, the desired temperature is set on the user control panel and the system will constantly adapt and change with the external conditions to maintain that temperature without further user interference. It does this by ensuring that the air introduced into the room is cooled or heated to the correct temperature with the degree of cooling or heating automatically adjusted. The temperature of air introduced to different rooms will differ according to the conditions in that location.

Winter is Coming

If you live in Brisbane, you would understand how dramatically 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 with layers of clothing on.

In case you haven’t noticed, winter is upon us 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.

What Is Reverse Cycle Air Conditioning?

A reverse cycle air conditioner is one that can cool your home in summer, and keep you warm during winter, all with one energy-efficient unit. It’s so brilliantly simple! Hands down, it’s one of the most efficient ways to heat your home using electricity.

Benefits Of Reverse Cycle Air Conditioners

They warm in winter
They certainly do, and it’s all about the heating technique! A reverse cycle air conditioner works very differently to conventional gas or portable electric heaters. Conventional heaters have to ‘create’ heat energy, while a reverse cycle system ‘absorbs’ heat from the outdoor air to warm the air inside, which is a more energy efficient technique.

When in heating mode, the unit works in the opposite way to cooling, in that it draws heat in from the air outside before distributing it around the room. To get a bit technical, 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, releasing heat into the room. It doesn’t have to be warm outside for the unit to do this, as it can perform this function even in freezing conditions.

Built with cold conditions in mind, a good reverse cycle air conditioner will have an automatic defrost cycle for more effective operation. So even when the mercury drops as low as minus 15ºC, your reverse cycle air conditioner can still heat your home.

They cool in summer
With a flick of the switch, your reverse cycle air conditioner is now in cooling mode. Again, using a super-energy efficient system, the unit will absorb heat from the inside air and dissipate it outside, leaving your home cooler. Today’s modern technology means your air conditioning unit can cool your home in temperatures as high as 46 ºC. So forget cumbersome or bulky fans. This is the perfect cooling system made for our climate.

They’re extremely efficient
The one word you’ll hear over and over again when talking about reverse cycle systems is efficient… efficient in terms of energy use, efficient in cost over time, efficient in heating, efficient in cooling. They really do provide one of the most efficient means of heating a home available.

In fact, modern reverse cycle air conditioning systems are becoming more efficient over time, particularly in terms of energy consumption and cost, making them a very good investment in comfort and health. And as electricity prices continue to rise, air conditioner efficiency is becoming increasingly important. They’re efficient even in the most extreme conditions. For example, one kW of electricity consumed, will generate three or more kW of heating or cooling.

When comparing energy consumption for different air conditioners, remember there are different energy ratings, so ask a specialist to explain what the numbers mean. As with other appliances, the more stars your heating and cooling unit has, the more energy efficient it is.

They’re adaptable and flexible
As part of a push for energy efficiency, many modern reverse cycle air conditioning units come with thermostats and advanced inverter technology, which means they’re able to adapt to the temperature and condition of the room. Inverter technology helps to deliver one of the most energy efficient ways to heat and cool your home using electricity. Unlike a conventional air conditioner’s on/off operation, inverter technology works like the accelerator of a car, gently adjusting power to reach the desired temperature faster, then steadily maintaining it without fluctuations, for uninterrupted comfort and more efficient operation.

More efficient than portable heaters
Reverse cycle air conditioning units are usually much more efficient than plug-in portable electric heaters, which can sometimes be cheap to buy but costly to run. Also, consider the size of the space you wish to warm with your heating source. Many portable heaters are only designed to warm a very small area like the ground around your icicle-cold feet, for example, and the heat may not emanate to a wide enough area to truly warm your environment, or your body, unless you literally sit on top of it, which is neither safe nor practical!

You only pay once
A particular advantage of installing a reverse cycle system is that you only pay once for a unit that performs two functions. All you need to do is change the unit’s mode to switch between cooling for those summer months and heating to quickly warm your home in the chilly winter months. Some Aussies actually live in an environment where they could use the heater one day and the cooler the next. So having a reverse cycle system could help make your home’s heating and cooling expenses much more efficient.

They help purify the air
Dust and smoke be gone! Reverse cycle air conditioning systems don’t just heat or cool your home, some split systems can actually purify the air inside it. Many systems feature a built in air-purifying filter that traps fine airborne particles, helping you purify the air inside your home. Some even decompose odours, and absorb and deactivate bacteria and viruses. Considering Australia has one of the highest rates of asthma in the world, as well as high levels of hayfever and other allergies, this is an unexpected advantage of a reverse cycle system and can make it an important factor when considering your growing family’s needs, not just in terms of heating or cooling, but in terms of health.

Less noise equals greater comfort
When it comes to a heating or cooling system, perfect climate control is the key factor that can affect comfort in your home, but it’s not the only one. Operating noise levels can also have an impact on comfort levels. Some manufacturers of reverse cycle air conditioning systems are investing in, and developing technology to reduce operating noise across their units, maximising a family’s comfort at every level.

Better for the environment
Here’s another fantastic advantage to choosing a reverse cycle air conditioner. These systems tend to produce only one third the greenhouse gas emissions of standard electric heaters. Some reverse cycle units that are rated above a 5 star energy rating such as Daikin’s only 7 star energy rated split system* (US7) will actually produce less than one fifth of the emissions of conventional electric heaters.

More split systems today are using the new R32 refrigerant with 66% lower global warming potential factor than R410A which is the common refrigerant type.

Less greenhouse gas emissions means a happier planet.

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 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.

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.

In Summary..

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, Advanced Air Conditioning have a special offer for you! You can have your Ducted Reverse Cycle system serviced from a low $210 inc GST, or a  Wall Split from $175 inc GST. Our offer ends VERY soon, so give us a call today on (07) 3256 6033 to make sure that your system isn’t costing you more than it should this winter!
