When it hits 40 outside, you’ll be glad you chose quality

Wall-mounted Reverse-cycle split system air conditioners are a fantastic choice for efficiently cooling and heating individual rooms. But the quality of your split system air conditioner installation in Perth is everything. It’s the difference between a system that struggles through summer, inflating your electricity bill, and one that stays cool on a 40-degree day. The difference between costly replacements and simple maintenance. The difference between a company that fits and forgets… and WestOz, a team of experts who respect your property and ensure your air remains fresh for years to come.

Easy on the wallet

Efficient at both heating and cooling, split systems provide reliable, year-round comfort without sucking too much juice.

Simple maintenance

With accessible components, split systems are a breeze to service and maintain, ensuring smooth operation all year round.
