What are Window Wall Mounted
System Service and Repairs

Regular service and repairs of window wall mounted system are critical for continued reliability to maintain the designed operating efficiency of the unit.

Regular inspections and checks on operating performance are easily completed with little impact on the operation of the system or inconvenience to those in the conditioned space. In most cases, cleaning of the filters and finned coil fans can be checked at 6 week intervals by the home owner or occupant. However, more detailed inspections conducted by Alliance Climate Control technicians are recommended at least on an annual frequency.

Such inspections are an invaluable tool to highlight any faults and prevent unplanned equipment downtime which may result in costly repairs and frustration of occupants.

At Alliance Climate Control, we strongly recommend such regular service inspections at an annual frequency and advocate scheduling a no obligation appointment in advance.

Professional job completed, good as new. I had jet lag and left Giannis to get on with it while I went back to bed. Job done, cleaned up and door locked behind him - I didn’t have to worry about a thing! 👍

I was very pleased with Alliance and in particular - Jake, Ken, Shadi, Asa and Qais. The whole company has been extremely professional and detailed. We have a challenging older house that didn't have air conditioning. Several people we spoke with weren't interested in our project or didn't have the knowledge to give us confidence in their ability to do the job right. From the first meeting Jake spent hours with us and climbed through our attic twice to ensure clarity in what was required. While the price was not the least expensive, Alliance stuck to their quote even with a couple surprises. Ken and his team were very knowledgeable with the installation and every potential issue was discussed and handled with a "can do" attitude. The team took care with our house and furnishings and most importantly the system works!

Shadi and his team were very dedicated and professional. They did a fabulous job and I am thrilled with my new air conditioner. They worked tirelessly in the difficult conditions- heavy rain which soaked them each time they had to go outside. They remained focused, cheerful and helpful and completed by cleaning up which I was most grateful for. I would recommend Shadi to any person looking for a reliable, proficient technical expert. Thank you 🙏🙏🙏

The three technicians -Andres, Ivan And Drugan who were involved in removal of the three air conditioners from our apartment and installation of three new ones, were very good. I was impressed with their team co-ordination, dedication and professional attributes combined with polite and friendly manners during the whole process. I will be grateful if the administrator/owner of the Alliance Climate Control convey our sincere appreciation in appropriate way to these three staff members.

The team did a wonderful job taking away my old air con and replacing it with a shiny new one in a tricky spot. They went the extra mile to put it where I wanted it and to problem solve the obstacles.

First time using Alliance Climate Control when our old split system stopped working. Contacting ACC and arranging an assessment was easy, with the onsite assessment and quotes provided by Alex. Arrangement of installation of our new system was quick, clean, and use and details of the system communicated by BJ and Yunus. All communication from the customer care team- Ilce and Zac- was easy! Can’t ask for more- easy, no fuss, clear communication.

Matt and Aaron from Alliance were terrific. They were courteous and efficient and nothing was a bother. As an added bonus, they left my house cleaner than they found it!Alliance are so reliable that we just used them again. Apart from aircon maintenance, they replaced an old and broken video intercom system and diagnosed why our outdoor lights aren't working. An outstanding job - and service! - from Chris, JJ and Vashil.
