My HVAC Hobby

Hello, my name is Nigel and I live in New South Wales with my partner and our three kids. I am really interested in HVAC systems. It isn't my job or anything, I just got interested in it. My friends often poke fun at me because of my unusual hobby but I don't mind. It all started when I visited my friend who is an HVAC contractor. He was working on a unit and he started to explain how the different components worked together. I was fascinated and when I got home, I took the cover off my HVAC system and cleaned it out. Since then, I have started to maintain and repair HVAC systems for friends if they can't get hold of a professional. I decided to start this blog to help others.

Four Fundamental Factors Taken Into Account During Split-System Installation

DIY jobs around the house are popular among a good number of homeowners because they can save money by avoiding expensive repairs. But when it comes to the installation of major systems in your home, such as new air conditioning, it is inadvisable to risk DIY installation. Air conditioning systems comprise a multitude of components that require intricate assembly. Overlooking one aspect of the installation process will not only lead to malfunction, but you could even irreparably damage the system. Thus, if you are replacing your old AC with a modern split system, then it is imperative to have it undertaken professionally. To help you understand the complexity of this project, here is a brief list of four fundamental factors that are taken into account during split-system installation.

Wall strength

A mistake you can easily make when you choose to DIY air conditioning installation is going ahead with the mounting of the units without taking into consideration if the walls in your home can bear their weight. A professional technician, on the other hand, will understand that before the unit is installed onto the sidewall, they have to run some tests to ensure the wall will retain its structural integrity. Moreover, they will know how to identify false walls and avoid them during installation.

Wall separation

When you see a split air conditioning system already installed, you may assume that the units lie flat against the wall. However, this is a misconception. When the outdoor and indoor units are being installed, the air conditioning contractor will allocate several centimetres between the unit and the wall. This space functions to ensure there is adequate air circulation when the split system is in use and subsequently minimise the risk of overheating. Furthermore, they will allow sufficient room both above and below the units.


You could be thinking that the best place to situate the exterior unit is wherever it will be unobtrusive in your yard. However, this is untrue. For the outdoor unit to function optimally, it needs to be in the perfect location. First, it should never be in direct exposure to the elements, especially rainfall and sunlight. Secondly, it should not be obstructed by any objects since it needs optimal airflow to ensure the heat it emits dissipates quickly.

Bracket tilt

One of the parts that the outdoor unit of a split system comprises is brackets. These brackets have the primary function of ensuring that the units installed inside the home receive an unimpeded flow when condensation is redirected away from them. To function their best, the brackets should be tilted at an angle or the indoor units will be vulnerable to breakdown.
