The following tips will help you ensure your air conditioner is both comfortable and economical all year round:
You can if you use it economically, if you close windows, doors, curtains and blinds, you can help your conditioner cool a room more quickly. Air Conditioners with inverters and auto settings are economical in power consumption because they automatically adapt and maintain the temperature you want.
You can leave windows and doors open, but it’s not a very good idea if you are trying to heat or cool your room. If you are trying to cool down a room, it’s best to close the curtains, blinds and windows during the hottest part of the day. This will keep your home cooler and prevent your air conditioner from having to work harder or having to use more energy then it has to.
An inverter in relation to air conditioning terms is a type of air conditioning system that incorporates a power conversion circuit which provides optimum power control and extremely efficient operation by changing the frequency of the power supply which varies the cooling or heating capacity. So even though you get accurate, smooth and flexible operation, you use less electricity than conventional units.
Please note that energy savings are only realised when the system is correctly sized. Undersized inverter systems will cost more to run.
A general indication is when the filter light flashes. But depending on the environment or the air cleanliness, in a normal domestic situation once or twice every season can be adequate.
For a commercial situation, filter cleaning should be carried out once every month.
Some indoor units are fitted with Catechin and various Air Purifying Filters, which have specific maintenance instructions. Therefore the individual instructions supplied with each unit should be carefully followed.
You will need to press the filter timer reset button. On wall splits and floor consoles you will need to remove the grille to find the reset button. With ducted, light commercial and commercial situations the reset button is on the controller.
It is OK to turn the power off, especially if you are away for long periods or not using your air conditioner for weeks on end. Most units have a low wattage crankcase heater that keeps the compressor warm. If the compressor is cold, damage will occur at startup. If you turn your air conditioner off at the PowerPoint, isolator or fuse box it must be turned on at least 12 hrs before use.
Ducted systems can be designed so that only parts of the house (zones) can be air conditioned at a time. Check that the zone switch is turned on.
During winter, most air conditioners defrost when the outdoor temperature is below 6°C. This mist is normal, it is only warm water vapour being expelled.
The operation manual outlines the requirements when placing plants near an air conditioner. Plants should generally be kept from direct exposure to warm or cold air being blown from both the indoor unit and the outdoor unit. Try to place plants out of direct drafts from the indoor unit. The outdoor unit should never have plants or any other material obstructing airflow. At least 1m of space in front and 100mm behind the outdoor unit is required for trouble free operation. It is also a good idea to ensure that leaves and vegetation does not clog up the heat exchanger.
Yes, if your air conditioner is correctly sized and you know what your master zone is (the amount of area that your system was designed to cool or heat at a determined temperature) you can turn on that quantity of zones If it is cooler than the design temperature you can run more zones ok alternatively If you want to cool or heat up an area more quickly you can turn off a zone of two (depending on your design).
The ‘Master Zone’ is an important concept in understanding which air conditioning unit is right for your home and for your family. This can be the difference between an outstanding result and one that is perhaps a little less than perfect.
Essentially, the Master Zone represents the largest workload that the air conditioning unit will manage at any one time.
The unit should be placed on a firm level base. A qualified installer should be consulted to determine the need for securing bolts on a case by case basis. It is always a good idea to strap the unit to a wall or roof if it is not fastened down at the feet to minimise the risk of the unit tipping over.
Manufacturers have detailed information on how to locate their specific equipment which is generally included in the installation manuals, however here is some information if no other information is available.
At the front (fan side) of the unit, no less than a distance of 1m is recommended for a small split AC and 2m for a large package AC. More would be preferable. At the back (no fan side) of unit, no less than 100mm is needed for a small split AC and 200mm for a large package AC. More would be preferable. N.B All outdoor units not only need a minimum distance around them, but also must be located so that the discharge air they blow out can escape away from the unit, and new ambient air can be taken through the unit. Careful consideration regarding location is required by an experienced installer.
On the side of the outdoor unit where pipes enter, maximum space possible should be allowed so that the unit can be serviced more easily. The minimum distance at the piping end should be 300mm for a small split AC and 500mm for a large package AC. At the end opposite pipes the minimum recommended distance is 100mm but more is preferable.
No, this is not recommended. If one remote is used to start more than one unit, the load on the power supply is much too great. Each indoor unit should have a separate remote control. In this situation each remote must be set-up by the installer to operate its individual indoor unit correctly.
No, ice on the outdoor unit is not a problem. The unit has controls that allow it to monitor the ice build up on the outdoor unit and will occasionally go into a de-ice mode to clear the ice. The full de-icing mode can last up to 30 minutes.
If the desired temperature has been reached in the room space then the indoor unit will slow the fan but continue to circulate a small amount of air so as to measure room air temperature. This air is actually at room temperature but may feel “cooler” because the indoor unit has stopped heating the air until the room temp falls again.
When the indoor fan is set to auto and when the air conditioner is set to heating mode the indoor fan can turn on and off automatically in order to provide the temperature conditions set by the user and also to protect the unit from icing up and other potentially damaging conditions.
It is completely normal for the outside unit to drip water, particularly when operating a window unit or in heating mode. The unit has a drain outlet and coupling supplied should you wish to connect a drain pipe to remove this water.
Soft/Dry/Dehumidification mode is used to de-humidify the room space. The unit does this by air conditioning for a minimum amount of time, which allows collection of moisture from the air without changing the temperature noticeably.
The correct size unit for a room is not only decided by room area, but also many other factors. Qualified assistance should always be sought when purchasing a unit for a specific room size.
Residential air-conditioners should be serviced at least once a year and commercial systems between 4 and 12 times a year (depending on the class of building) to ensure you get the maximum benefit from your investment.
Note - Some classes of buildings like nursing homes and hospitals need to be serviced to Australian standards once per month for compliance.
The outdoor unit is too noisy -
Yes, In addition to a basic service and filter clean or replacement, additional treatments like –
Some ways to resolve this are to.
Yes, A Daikin photocataytic air purifier can further enhance the quality of the air you breath by providing multiple levels of filtration and absorbs viruses and bacteria.
Apart from being highly illegal, and releasing ozone depleting, global warming substance , you can contaminate the system with moisture and foreign matter which will ultimately result in an expensive equipment failure.
Please call Refresh air conditioning for decommissioning, disconnecting and moving refrigerant lines legally.
If an air conditioner becomes dirty and is not regularly serviced they can smell, Another reason is when the system is working on cooling the heat exchanger becomes moist, if the unit switches to heating the bacteria in the moist coil can smell and soon goes away.
This is ok, it is the reversing valve changing the direction if the gas, on some systems you can reduce this noise by setting the controller from auto to either heating or cooling.
If your air conditioner is losing gas and needs regasing regularly It means that there is a gas leak and needs to be correctly repaired, sometimes it takes a while to locate tiny leaks but the time invested in a proper repair will offer the following advantages.
Check that you have power and the power is on.
Check the settings e.g. select either cooling or heating.
Ensure the if you are trying to cool an area check that the temperature setting is set lower than the actual room temperature.
Ensure the if you are trying to heat an area check that the temperature setting is set higher than the actual room temperature.
