Installing an air conditioning system is an important step in ensuring comfort in your home, but one of the most common questions homeowners ask is: how long does the installation process take? The answer depends on several factors, including the type of system, the complexity of the setup, and the condition of your home’s existing infrastructure.
In this guide, we’ll break down the factors that affect installation time, provide estimates for different types of air conditioning systems, and outline what you can expect during the installation process.
Factors That Affect Installation Time
Type of Air Conditioning System
The type of air conditioner you choose plays a major role in determining how long the installation will take. Some systems are relatively quick to install, while others require extensive work:
- Split system air conditioners – Generally take 4-8 hours, depending on the difficulty of mounting the indoor and outdoor units.
- Ducted air conditioning systems – Can take anywhere from 1 to 3 days, as ductwork installation requires more effort.
- Window units – These are typically installed within 1-2 hours, provided the window space is suitable.
- Portable air conditioners – Take 30 minutes to 1 hour for setup, including vent installation.
Size & Complexity of the System
Larger systems or those with multiple zones will naturally take longer to install. A basic split system in a small room is quicker to set up than a multi-zone ducted system that cools an entire house.
Installation Site Preparation
The time required for installation also depends on whether the home is already equipped with the necessary wiring, piping, or ductwork. If modifications or additional work are needed, such as upgrading electrical circuits or reinforcing walls, this can add extra time.
Weather & Environmental Factors
For systems requiring outdoor installation, factors such as bad weather, limited access to the property, or working in high-rise buildings can affect installation times.
Professional Installation vs. DIY
While some homeowners may consider DIY installation, most air conditioning systems require a licensed professional to ensure proper installation, efficiency, and warranty protection. Professional installation is strongly recommended, as incorrect setup can lead to inefficiency, higher energy costs, and safety hazards.
Estimated Time for Different Types of Air Conditioning Installations
Split System Air Conditioner
- Time required: 4-8 hours.
- What affects installation time? If new piping and electrical work are needed, installation may take longer.
Ducted Air Conditioning System
- Time required: 1-3 days.
- What affects installation time? The complexity of ductwork, roof access, and home layout.
Window Unit Air Conditioner
- Time required: 1-2 hours.
- What affects installation time? Whether the window space is suitable and if additional sealing is required.
Portable Air Conditioner
- Time required: 30 minutes – 1 hour.
- What affects installation time? Adjustments to the window vent may be needed.
What to Expect During Installation
Step-by-Step Installation Process
A professional air conditioning installation generally follows these steps:
- Site Inspection & Preparation – The technician assesses the area and determines the best placement for the unit.
- Electrical & Ductwork Setup – If needed, wiring and ducting modifications are carried out.
- Mounting the Indoor & Outdoor Units – The air conditioning system is securely installed.
- Connecting Refrigerant Lines & Wiring – The units are connected to ensure proper functionality.
- System Testing & Commissioning – The system is tested to confirm everything is working correctly.

Potential Delays & How to Avoid Them
- Permit approvals – Some installations may require council approval, which can extend the timeline.
- Structural modifications – If walls or ceilings need reinforcement, additional work will be required.
- Weather conditions – Heavy rain or strong winds may delay outdoor unit installation.
How to Prepare for a Smooth Installation
To ensure a quick and hassle-free installation, homeowners can:
- Clear space around the installation area to allow easy access for technicians.
- Ensure electrical requirements are met by checking power supply availability.
- Confirm installation details with the technician beforehand.
Last Thoughts
The time required to install an air conditioning system depends on the type of unit, the complexity of the setup, and any necessary modifications to your home. While a simple split system may be installed in under a day, more extensive systems like ducted air conditioning can take multiple days to complete.
For the best results, it’s always advisable to work with a professional installer to ensure efficiency, compliance, and long-term reliability. If you’re considering a new air conditioning system, consulting an expert will give you a better idea of the exact time required for your home.
