Did you know?
The U.S. has about 88% of homes with air conditioning, which consumes nearly 12% of the electricity in the entire system. [Source: U.S. Department of Energy].
Undoubtedly, air conditioners are now becoming widely popular compared to before for obvious reasons. Nevertheless, consuming a huge part of home energy can be a concerning factor, especially when it spikes. It might be because its installation time was inappropriate.
Most people are still unaware that air conditioning installation time can vary based on multiple factors, not just the time of year. First, understand what impacts air conditioning installation time, then learn when and how to service your air conditioner.
Here is the guide that comprehensively describes the impacts and provides useful suggestions.

KEY TAKEAWAYS
- Different types of AC units, including ducted, split system, and window air conditioning units, can influence installation time.
- Most of the air conditioning services are busy during peak summer, so consider calling them during the autumn or winter season to save waiting time.
- Compact or old home layouts may make the process difficult and time-consuming.
- Location of AC units facilitates their accessibility and the distance between units, affecting the installation duration.
- A weak electrical support network required a few modifications in the wiring circuit system, extending the time to set up a unit.
The Type of Air Conditioning Unit
The most significant factor influencing installation time can be the kind of system you are setting up. Since each unit has a different level of complexity that directly impacts the work required, one needs to understand all of them.
Ducted Air Conditioning Unit
Starting with the most complex and time-consuming installation system, the ducted air conditioning unit. This ducted system has a network of vents and ducts hidden in the ceiling or walls, cooling the entire home. From installing a central indoor unit to laying all the ductwork and setting up the order condenser, it takes 3 to 5 days to complete.
Split System Air Conditioning Unit
A split system is less invasive than a ducted one, making out to be a popular choice for many homes. See what it involves:
- Mounting an indoor unit on a wall and connecting it to an outdoor condenser unit via electrical wiring.
- The standard split system takes between 4 and 8 hours of installation.
Window Air Conditioning Unit
The quickest and easiest type to install is indeed a window air conditioning unit. A straightforward installation process that only involves a few steps:
- Securing the unit in the window.
- Extending side panels to fill the gap.
- Plugging in and getting started.
With professional help, it can typically take just 1 to 2 hours to install the window AC unit.
The Time of Year Your Air Conditioning Unit is Installed
Air conditioning installation time is highly dependent on the season scheduled. Because during peak seasons like a hot summer, demand for AC installation companies hits its peak. This eventually causes you to wait for a longer time–the period between your initial inquiry and the installation day.
To deal with the case, booking and installation during off-season, including autumn or winter, can result in quicker schedules and potentially better pricing (as installers are less busy these days).
Your Home Layout
Every home brings a unique set of challenges and opportunities for AC installers. Understand it with the help of some examples.
- An aged home and its construction material may not support the drilling and wiring process.
- Homes with tight rope spaces or difficult to access crawl spaces will take longer for a ducted system.
In both cases, a well-organized layout can simplify the process, while a more complex floor can add a few extra hours to the job.
INTERESTING FACT
An incorrect installation can lead to a new unit consuming about 40% more energy and eventually higher utility bills.

The Location of Your Air Conditioning Unit
The location of the air conditioning unit consists of two major factors:
- Accessibility: In a tight roof space, a ducted system takes longer to get set up. Similarly, split system installation can be extended if the installer has to run the refrigerant lines through compact areas.
- Distance between units: Again, for split and ducted systems, the material and labor are required to connect them. Hence, the time to install the unit may extend with the distance.
If Additional Electrical Work is Needed
Some air conditioners may need a dedicated power source to operate safely and efficiently. This is where you need an effective electrical system to handle the power requirements.
This process may involve:
- Installing a new circuit breaker
- Running new wiring from switch board to unit’s location.
As a result, the overall wiring process may take a significant amount of time and cost.

How long does a general AC installation take?
The duration is based on different factors. A simple window unit can take 1 to 2 hours, a split system usually requires 4 to 8 hours, and a full ducted system may take 3 to 5 days.
Does a home’s age affect installation time?
Yes. Older homes may have some structural challenges when installing the latest AC units.
Are ducted systems good for the home?
Not always, as it requires a lot of open ceiling or floor space.
What is the best time to install an AC unit at home?
Peak autumn or winter off-season at the best time of the year to get the work done quickly.
