A standard split-type aircon installation in the Philippines typically takes between two and four hours when conditions are straightforward, such as when the wall is accessible, the distance between the indoor and outdoor units is short, and the electrical connection is already in place. Window-type unit installations are faster and can usually be completed within 30 minutes to one hour. More complex installations involving longer refrigerant line sets, difficult wall materials like thick concrete or brick, high mounting locations, or the need for a new dedicated electrical circuit can extend the process to a full day, so it is best to schedule installation on a day when you can be home throughout the process.
