IMPORTANT NOTICE:
Please take careful notice of the "Ducting and Componentry" outlined below! This part of the ducted installation is equally as important as the quality of the air conditioning unit itself, and will be the difference between a system that costs you money to run and one that will save you in running costs in the long term.
Did you know that with inferior quality ducting, you can lose up to 10 degrees by the time the air reaches the room in heat gain/ heat loss alone?! If you are unsure of what type and quality of componentry our competitor is offering as part of their quotation, please contact our office to discuss these differences because they will absolutely make a difference to your running costs!
Ducting and Componentry
Ducting
• Superior R1.5 thermal rated ducting will dramatically reduce any potential heat gain or heat loss. Morphett Air Conditioning chooses to use Ductair's "ENERGY SMART" flexible duct with a 1.5 thermal rating, which exceeds the Australian building code for all of South Australia!
ALWAYS ensure that you are familiar with what thermal rating duct you are being offered because this is where you will either save money or waste money in running costs! Remembering that you will lose up to 10 degrees by the time the air reaches your room with inferior quality ducting.
So please be warned, many other componentry manufacturer's falsely claim that that they have superior duct because they produce a 75mm Polyester duct where "Energy Smart" duct is 60mm.
Sounds good in theory, however don't just look at the insulation thickness, it is more important to know the actual "thermal rating" of the duct. (F.Y.I .The 75mm Polyester ducting has a thermal rating of R1.0 and the 60mm Rockwool ducting has a thermal rating of R1.5! The insulating properties (or thermal ratings) tell us the full story!

The "FlexRight" system
• Unfortunately in the air conditioning game most installers tend to be a bit lazy and will cut corners at every opportunity. Sometimes when a duct length is a bit short, the installer will stretch the duct onto the ceiling register (or outlet). This will sometimes "kink" the duct as it connects to the register causing restrictions with air flow as well as placing unnecessary stress on the ducting.
At Morphett Air we have adopted a very clever idea that will eliminate both of these concerns by using the "FlexRight" system! The FlexRight is a small addition that we add to each outlet that connects to the neck adapter on the top of the ceiling register. (See below) With its unique arched design the fitting allows the duct to arch easily and connect to the neck adaptor allowing for perfect air flows.

Zone Motors
• "Siemens" heavy duty drive open/drive close Zone motors (NOT SPRING RETURN).
The motors are a "START/STOP" motor and ARE NOT continual drive motors that most air conditioning companies offer.
With a continual drive motor that most of our competitors offer, it is necessary for the motor to continue to "run-on" for the entire duration that the zone is open! Start/stop motors will only activate for the open or close function and will sit idle at all other times.
Siemens zone motors are backed by a 15 year warranty on replacement of motor AND INCLUDES 15 YEARS ON LABOUR. The labour warranty is also a rarity in this industry.
Return Air
• Return Air "Egg Crate" grilles with removable filters.
Surface area here is critical.
If a return air grille is undersized, you will dramatically increase the noise levels, resulting in whistling. We will also ensure that regardless of distance between the Return Air Grille location and the indoor unit, we will use as an absolute minimum of 6 metres of flexible ducting between the two. This will further ensure that the Return Air is as quiet as possible.
• Return Air Ducts are Acoustic enhanced.
Unlike most air conditioning suppliers Morphett Air chooses to use R1.2 Rated (Tested to Australian Std AS4254) ACOUSTIC ductwork from the return air side of the unit to your Return Air grille(s). The inner skin of this duct is lined with a black acoustic fabric, preventing any potential noise relating to airflow and noise transfer from the indoor unit in the roof space. The outer liner is a tear-proof and fire resistant foil.
Joiners (Y- Collars)
• Metal Collar Y-piece joiners with V-clamp system and are insulated with foam spray.
The V-clamps on each fitting prevent ducts from blowing off of the fitting which is an extremely common occurrence with plastic fittings. (We will not use plastic fittings under any circumstances!)
Ceiling Outlets (Supply Air)
• Multi-directional ceiling outlets with ADJUSTABLE BLADES.
With the outlets used in our systems, not only can each section of the outlets be faced in one of four different directions, but the actual blades can be manually adjusted to any pitch or angle desired. The adjustable blades are extremely beneficial for taller ceilings because when on a heating cycle, we know that hot air rises.
Upon commissioning of the system, we will position the angle of the blades to be almost vertical. This will then allow the warm air to be pushed to the ground. The majority of our competitors will use "fixed blade" outlets and the only reason being is because they are cheaper to manufacture. The disadvantage here is due to the angle of the blades being fixed, most of the warm air stays up and around the ceiling.
Air Balancing
• Each outlet is fitted with an additional Manual Damper Blade to ensure even airflow distributions when air balancing the system.
As standard practice, we will ALWAYS air balance the system to ensure that the air flows are similar in each of the rooms. Without air balancing a ducted system, you will always find that there is too much air in some rooms and not enough in others. An age old and very common problem experienced.
