Window Wall AC System
Window wall systems are popular because of their simple look and operation. It forces hot air outside, making the air indoors cool and more comfortable during the hot summer days.
What is a Window Wall AC System?
Window wall AC systems are fairly common and in demand due to their straightforward construction and use. These air conditioning units use refrigeration. Warm air is drawn in from the sides, hot air is forced through the condenser coils and cooled air is forced over the evaporator coils within.

Low Cost
Window air conditioners’ inexpensive and reasonable cost is their primary advantage. They are not only reasonably priced to buy, but they are also quite economical to run on a monthly basis.
Extremely Energy Efficient
Most window air conditioners have excellent energy efficiency ratios, which help you compare how much space they cool to how much energy they use to operate them. If you want to save the most energy possible, choose a window unit with a high energy efficiency rating.

How good is Teknicool?
We've had a ducted air conditioner installed on mounts that were required last year and also had it serviced. The Teknicool team have been great to deal with and definitely recommend. Sam and the team have been nothing but helpful and professional. I do not usually leave reviews but am doing this for the great work, ease in dealing with the teknicool team and hassle free process. Really appreciate the hard work!
Highly recommend this business. Very professional, great price, and very efficient. Sam recommended how to upgrade our old ducted air system for our 2 storey home. We have a much quieter and sleeker unit. They cleared away old existing aircon and left our place very tidy. Glad we found this business online through great reviews.
Very happy with Sam and his team. Quoting was quick and easy. He helped me get strata approval within 24hrs. The install was quite difficult but he managed do it while not charging any extra for the complexity. Will definitely use and recommend his services again in the future.
Sam and his team installed a ducted air con unit for my house. The whole process of getting the quotes, advice on units and planning was efficient. Easy to communicate to and straight to the point. No fuss. Price was the best of my 4 quotes. Sam provides the information and allows input but at the same time give honest opinions.
Sam & and his team were very polite, courteous and thorough. Absolute minimum of mess, resulting in the absolute minimum of clean up. It is Sam's business and so he is always protecting it. Did not leave until he had tested each "zone" for air flow. Explained digital display and pre-set all that he could. No hesitation in recommending his company, right down to initial contact when he did an on site inspection & quote.
Sam and the boys turned up ontime and firstly explained what they were going to do, they then did the installation and cleaned up on completion. The price was very competitive and Sam also gave us some advice on some electrical issues he spotted in the roof. Great service and value for money. Trevor
Had a Daikin Cora 4.6 split system installed in my 2 bedroom unit last week & I'm very happy with it. It's so quiet inside & outside. Perfect for apartment living. Although I haven't had the opportunity to really use it for a longer period, but I know I will have a very comfortable summer this year. Sam advised me via many emails the best unit for my situation & was always very quick with his responses,.
Great business to deal with. Everything was upfront and the process and install was simple. Also helped removed the old unit.
Teknicool were a pleasure to deal with from start to finish. We ordered a split Daikin air con unit for our home and Sam was very helpful from the opening phone call, subsequent home visit to quote and finally the installation. They returned my phone calls in a timely manner, turned up to scheduled appointments on time and also phoned me before the appointments to let me know they would be arriving soon.
Sam and assistant did a great a job installing my Air con unit.They were extremely efficient, methodical and they didn’t leave a mess. I am very pleased with the service I have received. Teknicool was highly recommend to me by my son in law and I will surely be recommending them to family and friends.
My husband and I are very happy to have chosen Teknicool air and we will definitely recommending! Sam installed our ducted air con system and is the best thing we did for our home. From customer service to installation we were very pleased with Sam's professionalism, honesty and knowledge. Sam booked a date for installation suiting our needs and there was no delay. Ticked all the boxes for us.
Super impressed with the professional, timely and efficient service from Teknicool. We were offered very affordable prices, our options were clearly explained without any pressure or persuasion, and the installation was done professionally, courteously and 100% on schedule. I highly recommend this business, we will certainly work with them again next time we need to replace another one of our older units.
Thanks for doing a great job installing our AC, for discussing the vent and unit placements beforehand and for explaining how it all worked. It’s working well and looks great, especially the customised hallway exhaust vent. Great value for money.
Sam and his team were absolutely fantastic for my ducted air-con install. I had 4 different air-con installers come to look at the job. 3 of them said that ducting to back part of my house wasn't possible due to a flat roof extension. Teknicool were the only ones to say it would be fine. And it was. Making the impossible, possible. And their prices were really good too. They were on time, professional and courteous.
These guys are great. Sam and his team installed our Daikin air conditioning system in a very efficient manner at a great price. The highlight of the installation was that the team managed to install an air conditioning outlet on flat roof extension area (which was considered almost impossible to install!) which we normally use for entertaining. This is a huge value add for us.
Sam and his team installed our 3 zone today and they did a really amazing job. Right from the very point when we first contacted Sam, he listened to our requirements and made very helpful suggestions. When he came out to site with his team, they were really efficient and ensured nothing was damaged while drilling holes and cutting out the outlets for the vents. I would not hesitate in recommending Teknicool for any air conditioning work!
Sam and his crew did a great job installing our new Split System Daikin air conditioner. They did not try to upsell me, they suggested a smaller package given the area size, which I really appreciated. The installation job was done quickly, in an hour, and very professionally, no mess. Polite, friendly service. Very smart idea to give prices for standard back-to-back packages on the website as well.
Sam was very helpful from the planning phase right through to the installation phase. Where other installers were recommending me to install a bigger KW system, Sam advised a smaller system was more appropriate for our townhouse and usage. This saved money for the installation and will save me for the ongoing running cost.
We recently had our ducted air conditioning replaced. My dealings with Sam right from the beginning was professional, prompt and honest. Sam provided the most appropriate options and did not over sell which was refreshing. It was great dealing with a local company, that showed up at the time. I would recommend Sam and Teknikool Air conditioning Team.
I cant recommend TekniKool highly enough. We were recommended to them by our neighbours and Sam lived up to his name. He arrived on the day he said and on time. He arrived with his team of 3 and installed a 12.5Kw ducted system within 6hrs . This was in a 2 storey house with 5 outlets and 3 different zones and a complicated roof space. I did pay for the AirTouch3 system which gives me access via my phone with its own App.
