This air conditioning FAQ is predominantly for Daikin systems, although many pointers will apply equally to any other brand of air conditioning system.
Hopefully this helps with waiting for office hours to talk to someone, and could save you a call out fee too.
However if you require a service call after reading this please go to air conditioning service.
Air Conditioning FAQ – Problem Solving
Indoor dirt, dust and debris can build up inside the air conditioner; mix this with humidity and the condensate drain can get blocked. Regular servicing should keep this clear. Condensate drains can be run into down pipes of the house; if this get blocked with leaves and debris, it can back up your condensate drain. If your water is coming from the indoor unit switch OFF immediately and contact Peninsula Air Conditioning.
Indoor Units – If your indoor unit is in the roof there will be a safety tray installed to catch any condensate that overflows, this will then drain to a small pipe coming out of the side of your house, usually just above the eve. If you see this leaking, switch OFF your system immediately and contact Peninsula Air Conditioning.
Outdoor Units – The condensate drain on the outdoor unit works when the system is on the heating mode. A drain kit may have been installed at installation. If this is not the case, it maybe possible to install a drain kit for you. Water can also come from your outdoor unit if it’s iced up. This can mean that that there is a problem with the system… generally a refrigerant gas issue. Contact PenAir for service.
If there is no display on the remote check the batteries. To remove the batteries slide the remote panel down to reveal the other buttons, when it stops give it an extra tug to slide the panel off completely. The battery compartment should now be exposed. If replacing the batteries does not fix the issue, then make a note of the model number (ARC) on the back of the remote and contact Peninsula Air Conditioning for a replacement.
Alternatively, there are some remotes that can be purchased from our website – visit our store. If the remote has a display but it is not controlling the air conditioner, there maybe an issue with one of the boards inside the air conditioner. Try resting the system from the main power source, switch the power to the air conditioner off and leave off for 20 to 30 minutes. When you switch the system back on, leave it for 15 mins to gather itself. If you continue to have issues you will need a technician to assess.
Fixed Wall Controllers
If your wall controller isn’t working, check that the main power to your air conditioner is on. Check the isolator switch by the outdoor system along with the trip switch in your fuse box. If these are all on contact us.
- The repair required is going to take a few hours. Sometimes the system needs a lot of time spent on it to repair, and in these circumstances we would need to arrange to return to complete this. We will have other jobs booked in for that day and we cannot anticipate how long a repair will take without a technician assessing first. If this is the case the technician will be report his findings to the office and our repair recommendations will be emailed to you. Once this is accepted we will schedule in our soonest available date for repair.
- Parts are required – Air conditioning systems are made up of lots of parts, both electrical and mechanical, and each model has different parts which are generally not interchangeable. It is not possible for us to have every part for every system with us. If this is the case the technician will report his findings to the office and our repair recommendations will be emailed to you. Once this is accepted we will order the parts and as soon as they arrive schedule you in for our soonest available date for repair.
- Two Technicians are required – Health and safety of our technicians is paramount. If it becomes apparent that the access is difficult and/or unsafe we would have to return for further works with two technicians.
- The age of the system?
- How much is it going to cost to replace the system?
- How much is the repair? Taking into consideration that other faults may occur after the initial diagnosed fault is repaired.
- Warranty period on parts/repair compared to a replacement.
- Wait time for repair – for some older system parts can be unavailable or even have to be sourced from overseas, and these can take 6-8 weeks minimum.
We would say it’s worth paying for a technician to assess the faulty system before making a decision. If you decide to go with a replacement rather than a repair we will credit your Diagnostic Callout fee.
- If the “Operation” lamp is on, the system is in its normal operating condition. It may not restart immediately because one of its safety devices has activated to prevent the system from being overloaded. The system will turn on again after about three (3) minutes.
- In cooling mode the air conditioner will not start blowing air until such time as it has cooled the fancoil such that any air produced is cooled. This is to avoid blowing warm air before cooling has taken effect.
- Wait one minute until the micro computer is prepared for operation.
- Check to see if there is a power failure. Wait until power is restored. If power failure occurs during operation, the system automatically restarts immediately after the power supply recovers. Check if a fuse has blown or circuit breaker has tripped.
- Change the fuse or reset the circuit breaker; switch off and leave for 20 minutes then switch back on again. If the system fails again or there is still no power call Peninsula Air Conditioning for repair.
- Check if the air inlet or outlet of the outdoor or indoor unit is blocked by obstacles. Remove any obstacles and make the area well ventilated.
- Check if the air filter(s) is/are clogged. Clean the air filter(s) (This is done with a soft clean cloth – if stains are difficult to remove use water. The filters should be cleaned at the start of summer and the start of winter.)
Check the following:
- See if the air outlet of the indoor or outdoor unit is blocked with obstacles. Remove the obstacle and make it well ventilated.
- If the air filter is clogged. Clean the filters.
- What temperature the system is set to.
- If the fan speed control is set to a low speed.
- If the doors or the windows are open. Shut doors and windows to prevent external air from coming in.
- See if direct sunlight enters the room. (When cooling) use curtains or blinds.
- When there are too many occupants in the room, the cooling effect is decreased, as there is too much heat in the room.
- Check if the heat source of the room is excessive. The cooling effect decreases if the heat gain of the room is too large.
Air Conditioning FAQ – General Questions
- Check your filters are clean – if they are clogged this restricts the air flow and the system then overworks and gets noisy trying to draw in the required air.
- A fan could be out of balance, or a problem with the fan motor. Contact Peninsula Air Conditioning for service.
- If you have a ducted system with zones, one of the zone motors may be faulty. Contact Peninsula Air Conditioning for service.
This happens when the smells of the room, furniture or cigarettes are absorbed into the unit and discharged with air flow. An internal clean of the system is recommended. Contact Peninsula Air Conditioning for service.
Vermin can rips holes in the duct and make it their home, especially if it’s underfloor. Live and dead vermin have been found in ductwork on several occasions. Contact Peninsula Air Conditioning, we can assess and remove the offending animal if possible. We may advise that you need a pest controller to attend as well.
Slide the remote panel down to reveal the other buttons. Find the mode button – this will toggle between various operation modes: Dry (rain drops), Cool (snowflake), Heat (sun), Fan (fan) and Auto (A in a box). Each press of the mode button will switch between each of these different modes. Select which mode you would like.
Note for Multi-Split systems – one outdoor unit to multiple indoor units. When more than one indoor unit is operating, priority is given to the first unit that was turned on. In this case, set the units that are turned on later to the same operation mode as the first unit. Otherwise they will enter the ‘Standby Mode’, and the operation lamp will flash — THIS DOES NOT INDICATE A MALFUNCTION COOL / DRY and FAN mode may be used at the same time. However, if AUTO / COOL / HEAT are required, then the required mode has to be selected on the first unit to switch on with the others to follow suit.
Fixed Wall Controllers
There will be a mode button on the wall controller, this will toggle between various operation modes:Dry (rain drops), Cool (snowflake), Heat (sun), Fan (fan) and Auto (A in a box). Each press of the mode button will switch between different modes. Select which mode you would like.
These generally have two types of filters, a standard filter and a bio anti-body filter. If you have the model number of the system, we can order them in prior to your service. Alternatively, we can carry out a general service, take details and order the filters. Daikin Split System Air Conditioners feature air purifying filters that not only trap most microscopic airborne particles, but also help to decompose odours, and absorb and deactivate bacteria and viruses.
This depends upon your setup and location of your return air and filter type; also sizes can vary. The main ones are…
- Cloth filter/media – which can be washed and vacuumed. Over time the filter media will need replacing or a whole new filter with frame will be ordered in for you. These are not always standard sizes and generally have to be custom made.
- Filter Boxes – These are cardboard filters coming in standard sizes and generally need replacing on a regular basis. Green filters are the standard pleated filters, white filters have better filtration with finer media blend – great for Asthma suffers.
- Purtech filters – These filters fit Purtech return air grilles and have a plastic surround with a nylon mesh and come in 3 different sizes. These will last a long time and can be washed with warm soapy water.
- That all doors and windows to outside are shut.
- Close all blinds.
- Keep doors to unconditioned areas closed. (laundries, bathrooms, etc)
- Air coming out of all outlets.
- The correct thermostat has been selected. (Ducted systems)
The Daikin Cora Split system also has a sophisticated titanium apatite photocatalytic air purification filter that traps even microscopic airborne dust particles, absorbs bacteria and viruses, and even breaks down odours. A well maintained air conditioning system can only contribute to a healthier environment.
- Because it controls humidity, the growth of dust mites and moulds is reduced. Air conditioning maintains humidity levels of 40 – 60% which is a great feature for people with allergies.
- All units are equipped with a filter. The effectiveness of a filter includes: catching dust, pollen, bacteria, viruses, odours, and even microbes and smoke.
- Additionally, extreme heat has a clear negative impact on the intellect and on physical activity and the use of air conditioning can go some way to rectifying this.
- It improves comfort levels at work and at leisure.
- Improves job performance.
- It can result in increased physical and intellectual activity.
- A lower temperature reduces the presence of insects and parasites.
- Lower temperatures mean less sweating, reducing the risk of dehydration.
- If the air conditioning installation is good, and if it is well maintained, it renews and improves air quality.
Air Conditioning FAQ – Service Questions
An annual service is usually sufficient for most domestic environments, however there may be times where we advise more often.
This can vary and is dependant upon location and type of usage, such as server rooms, medical areas, etc. For some clients an annual visit is sufficient, however others may require service as frequently as monthly. If you are interested in a commercial maintenance contract contact Peninsula Air Conditioning to arrange for a technician to assess the best course of action for you.
It depends on the time of year and what’s already scheduled, but as an average about week. At quieter times we can usually fit you in sooner; at busy times there can be a 2 to 3 week wait. So if it’s just a service you are looking for, contact us during Spring and Autumn rather than waiting until Summer/Winter
Quote for installation of new system
Again, depends on time of year, but as an average about a week. Again Spring and Autumn are good times to start thinking about getting quotes. At busy times, such as October/November we can get booked up 2 to 3 weeks in advance. If this happens we stop taking on bookings and would ask you to contact us again in a week or two’s time if you’re still wanting us out to quote.
Lead time from acceptance of quote to installation.
We always try to book appointments for the soonest available date. In quieter times this could be just a few days, busier times can be u a few weeks. We can advise at the time of acceptance.
