Time required to install a new aircon

New aircon installation is a tricky yet doable DIY task. It would help if you analyzed the factors to estimate the required time to complete the project. Aircon Installation Services Singapore suggests the following key factors to assess the time to install a new aircon in Singapore.

Factors Affecting Installation Times

Type and Size of AC Unit

The type and size of the aircon system significantly impact the installation duration. Standard split system units, commonly used for single-room cooling, typically take 4 to 8 hours to install. 

On the other hand, more complex systems like ducted aircon or multi-zone setups may require 1 to 2 days or even longer. The size of the unit also plays a role, as larger units involve more components and require additional time for setup and configuration.

Existing Infrastructure

The condition of your home’s existing infrastructure can affect installation times. Homes with existing ductwork, electrical wiring, and suitable mounting locations for the unit often have shorter installation periods. 

On the other end, homes that require extensive modifications, such as new ductwork or electrical upgrades, may experience longer installation times as additional work is needed to prepare the space for the new system.

Location and Accessibility

The location and accessibility of the installation site are critical factors. Ground-level installations are usually quicker and more straightforward than rooftop installations or installations in hard-to-reach areas. Clear pathways, enough space for equipment, and easy access to electrical connections result in a smoother and faster installation process.

Complexity of Installation

The complexity of the system and the installation requirements impact the overall installation time. Systems with additional features may take more time to install. These features include zoning capabilities, programmable thermostats, humidity control, or integrated smart technology. Customized setups or specialized requirements also contribute to extended installation periods.

Preparation and Site Readiness

Proper preparation and site readiness are essential for an efficient installation. Clearing the installation area, ensuring suitable ventilation, and having all necessary tools and materials ready beforehand can streamline the process. Any required permits or approvals should be obtained in advance to prevent delays and ensure a smooth workflow for the installation team.

Professional Expertise

The installation team’s experience and expertise significantly impact installation times. Trained professionals like LS Aircon Servicing Singapore, familiar with the specific model and installation procedures, can complete the job more efficiently and accurately. Their knowledge allows proper equipment setup, wiring connections, and system testing, reducing installation duration.

Additional Services

Additional services such as ductwork modifications, electrical upgrades, or structural adjustments can enhance the new aircon installation time. Coordination between different contractors or service providers may also impact the timeline. 

Homeowners should discuss any additional services required during the initial consultation to obtain a detailed timeline and cost estimate for the entire project.

Tips for Efficient Installation

  • Plan Ahead

Scheduling the installation during favourable weather conditions and planning well in advance can help avoid delays. Homeowners should communicate their preferred installation dates and specific requirements with the installation team to ensure a smooth and timely process.

  • Communicate Clearly

Clear communication between homeowners and the installation team is essential. Discussing expectations, project timelines, and potential challenges upfront can prevent misunderstandings and ensure the installation progresses smoothly.

  • Obtain Detailed Timeline

It is crucial to obtain a detailed timeline and installation plan from the contractor before the process begins. The timeline should outline the sequence of tasks, estimated completion time, and any milestones during the installation process. Having a clear roadmap helps homeowners track progress and manage expectations effectively.

  • Prioritize Professional Installation

Investing in professional installation services is key to a successful and efficient installation. Trained technicians have the expertise to handle complex installations, troubleshoot issues, and ensure the system is installed correctly and optimally. Professional installation also helps maintain warranty coverage and long-term performance.


In conclusion, the time required to install a new aircon system varies depending on several factors, including the type and size of the AC unit, existing infrastructure, location, complexity of installation, preparation, professional expertise, additional services, and testing procedures. Standard installations may take a few hours, but more complex setups can extend the timeframe to a day or more.
