HVAC ducting designs come in numerous of types at this time. Basically, this situation is purposed to accommodate various requirements of many custumers. But on other hand, sometime it can make some custumers confuse to choose and determine the best one of them! Some popular issues that usually must be considered well when choosing and discussing about them are; evaporative model, reverse cycle mechanism, acoustic mechanism, insulation accessories, fire-retardancy issue, etc.

The other factor that influence when understanding what is the best criteria of HVAC ducting system that match to your requirement is about the central nervous system of your house comfort level. Generally, the air circulation has super important function that can influence your HVCA system can work optimally and efficiently or not! It is usually dependent on the good windows and surely the insulation. Generally the air circulation consist of three major mechanisms that are; (1) the air supply process, (2) air converting (the time when the air will be cooled or heated), and (3) return air process! Ok, below are some common forms of ducting designs that you should understand clearly!

Evaporative ducting;

It is popular system which uses a single duct mechanism with one inch of insulation confining the core and has larger designed in diameter than others particularly if compared to reverse cycle model! This system usually only has not many period for cooling and heating effect to be processed, therefore the air circulation on these designs must flow super quickly.

Reverse cycle;

It is the ducting system that also familiar called as heat pump system and usually consist of several major parts that are; (1) the unit itself (heat pump device), (2) ducting design, (3) vent, and (4) grille (it has function to re-circulate the air back to the system). An air filter usually is already attached in the grille. The outside air temperature has important function that can influence the reverse cycle significantly when working because it extracts the heat gape from the not-indoor air.

Some experts recommend this system because it can work efficiently and just only need one-third energy cost of units that use direct heating concept. And factually it can be utilized up to more than 15 years (it is so durable, isn’t it). It also can be functioned to provide effective refrigerative cooling system. Not only that, it also come with various modern technologies and features such as inverter technology, portable style, split installation, thermostat, etc. In addition, it must be insulated with minimal 2 inches of material enclosing the core in order to prevent of heat & cool energy losing quickly.

Acoustic ducting designs;

They are also popular known as whispaflex model. They use reverse principle of reverse cycle method. The big benefit when using them is about their quietly ore noiseless performance as obvious as their familiar nickname since they have tiny holes in the interior core. The tiny holes are excellent deign that will decrease the loud noise inside of the ducting when running.

HVAC ducting fire retardancy and insulation types;

There are currently available variety materials of insulation and you will find the fact that polyester becomes the dominated and popular standard model at this day. What is polyester? Well, it is similar like fiber that usually used for people’s pillows. The other popular insulation material is fiberglass that usually offered relatively more expensive but they promise better quality and performance than polyester model. In addition, considering about fire retardancy is related to the fire laws that each area has different value! Therefore don’t miss to consider about it that will meet to the right specification of your local area where you live.

Additional information about the long warranty;

Checking about the long warranty is the basic and simply procedure that so useful and helpful to save your money in the future (at least in the next few years). Well, five up to ten years or more are general standard long warranty of ductwork. And factually, most of ductwork models will become quite aged after ten years. The frequently factors that can decrease the reliability of ductwork is rodents (such as rats, mice, etc) and build up of bacteria .Therefore the proper maintenance like regular duct cleaning maintenance as well as based on the manufacture’s instructions must be obeyed as well.
