This content hopes to give you a useful knowledge base on Air Conditioning at hand, no matter what your previous skills and experience on the topic. People often wish to know whether they are able to change their existing ducted evaporative system to a new ducted reverse cycle (HVAC) ac system by utilizing the same ductwork and outlets. The easy answer isn't any. Below is a summary of reasons why you can't simply change the machine over to become reverse cycle (HVAC) system. Firstly, reverse cycle grilles (or outlets) are often placed near windows and from the doors. This enables the air to condition the heat/cold that is available in directly through the windows. The airflow for a reverse cycle system also needs to take the longest route right back from the outlet to the get back air grille. If an outlet was placed alongside a door, the air would simply be sucked back beneath the door towards the get back air grille and the area would have hot spots close to the window. The problem with evaporative grilles is that they're usually located by the doorways. The evaporative units airflow should just take the longest possible path via a room and from the window. When they were located right alongside a window, the air would simply flow out the window and hot spots will be caused close to the doorways and in the far side of rooms. Due to these reasons it's not advised to put reverse cycle grilles in a same spot the place where a ducted evaporative grille was once located. Although you'll be able to do it'll severely lessen the effectiveness and capacity of the machine. The smartest choice is to begin fresh and put the brand new reverse cycle grilles in the right desired location as required. However, this means you will have to patch and paint the holes in the ceiling left by removing the old evaporative grilles which is a expensive job. Another option is always to add extra grilles as needed. You are able to consider leaving grilles close to the doorways from the evaporative system and add extra grilles by the windows if needed. Special Note: If you copy and paste the term “call air conditioning guy” into the search box of Google, you will be resulted with a lot of useful information and ideas about mcdonough heat & air which is one of the useful subjects that most people search for. Another problem undergone when swapping the systems over is that the old ducting can't be used. The ducting employed for evaporative units is far bigger than that necessary for reverse cycle ducted ac units. Evaporative units use ducting round the 16-20 inch mark. This large size duct can be used by evaporative ac units as the air is very fast blowing also it aims to attract air to the quantity of 40 times the cubic area of your property per hour. Reverse cycle ducting is mainly only round the 12 inch mark in diameter. The reason being reverse cycle ac is far slower moving than it's evaporative counterpart. Evaporative ducting can also be usually only slightly if insulated. Reverse cycle ducting must always be insulated by no less than 2 inches to preserve the cooling/heating and also to prevent condensation from occurring. So if you wish to swap your present evaporative system to a new reverse cycle ducted system, you are better to start from scratch. Make sure to get a number of quotes for the price to patch and paint the ceiling before beginning any work. And when air conditioning contractors let you know they can easily swap something over utilizing the existing duct and outlets, ask plenty of questions and become wary because they might not be around to assist you once you have paid good money as well as your system isn't working efficiently.
