Roof mounted installation in two identical townhouses

These two townhouses each had 6 wall split systems installed. 1 x Samsung 7.0kw AR24FSSSBWK1 and 5 x  2.5kw AR09FSSSBWK1. These units covered the open plan living area, bedrooms and study. As you can see the right and left sides of the house are butted right up against other properties. This made it impossible to locate the out door units at ground level down the sides of the townhouse.

Our solution was to mount the units on the pitched roof. Understandably the client did not want to have the outdoor units visible from the front so we moved them all as far back as we could from the street. Installations like this add cost to the project as more materials and labour is required. Unfortunately in a situation like this, the back area of the house was already taken by the hot water service and water tanks.

Another option for this client was to install multi split systems. These units are capable of running multiple indoor units with only one outdoor unit. It is a great solution for properties that do not have the space or are difficult to install in for what ever reason. The client decided not to due to the extra costs involved in installing a multi split system air conditioner.

Roof mounted installation on a pitched colour bond roof

In some cases people will choose to install the outdoor unit up on their roof to keep it out of site. In this installation it was decided because most of the house had decking around it that was used alot for entertaining and the back side of the house didn’t have enough space between the house and the fence. It would have restricted access for things like rubbish bins, wheel barrows and generally moving things in and out of the back yard.

The pipes go out and straight up into the eaves and through the roof to the air conditioner. The drain was neatly saddled to the side frame of the doors and down under the dacking to a drain. Lifting units up onto pitched roofes like this requires safety harnesses and railings and adds costs to the installation. But as you can see, the finished job is nice and neat and the air conditioner hiden from view from the front of the house. It is also hidden when standing down on the decking.

Roof mounted installation on a pitched tile roof

The body corporate on this installation we adamant that the outdoor air conditioners had to be located on the roof of the building.

The roof is a pitched tile roof.

We located the indoor units on an external wall to allow us to get the pipes and drain outside. At that point we run the piping up through the eaves and run the pipes through the roof to the out door units. The pipes exit onto the roof out of a cut out section of tile that is then weather sealed.

The drains run down out of the duct cover and across the outer wall to the closest down pipe. The use of a scissor lift was required to get the air conditioners onto the roof. Fortunately we were able to take that into the carpark on the other side of the building. All the work done on the outer side of the wall was done using a ladder.

Complying with body corp requirements can be annoying and also add considerable cost to a job.

Roof mounted installation on a flat roof

In many new homes, apartments and townhouses the design allows for air conditioners to be mounted on a flat roof that runs all or at least on parts of the exterior of the building. This is a perfect location for air conditioners located on a second floor of the dwelling.

Not only does it simplify the installation it is an opportunity to have the out door unit up out of the way and in many cases hardly visible.

It does require lifting the unit onto the roof which is work in its self so it is a bit more complicated than a single storey installation and will cost some more.

Even better if the units can be located on the blind side of the home in an aesthetic sense.
