Still impressed 3 weeks later! Had my aircon installed by 81 Aircon and wanted to wait before reviewing to ensure everything works well. Peiee from sales was patient and thorough in addressing all my questions. Kannan and his colleague handled the installation professionally with clean work, punctual timing, and took time to explain the maintenance. Three weeks in, the unit is running smoothly with no issues whatsoever. Highly recommend 81 Aircon for their quality service and reliable workmanship!
