Replacing our devices is part of our lives, and we know that when we invest in an appliance, we will have to maintain it properly, and no matter how good it is, sooner or later, we will have to change it and get a new one. The whole-home AC systems are the most popular type nowadays, and they are going to help you cool down several rooms of the space without having to invest too much or complicate the process. Even though they are durable, there will be a time when you need to change them and get new ones installed. If that time is due, you are probably wondering how long does it take to replace a central air conditioning unit, and here we will answer that question and give you more information about the process.


Before we get to the main question, let’s first see what are the things that are going to affect this and what you should expect depending on the type of unit that you have. The size is going to make one of the biggest differences, as well as the access to the location of the existing unit.

The systems that are smaller, easier to take out, and easier to install are going to take much less time when compared to the ones that are large, bulky, and heavy. If you have a big unit that will need to be carried by more than one person, the whole demounting process is going to be much more difficult and it is going to take far more time.

On the other hand, if the unit is relatively small and light, and if the crew can be just one person or two at the maximum, chances are, the whole ordeal is going to be finished in just a few hours.



The next thing that is going to have a huge effect on the process is the location of the system. If there are no obstacles between the units and the workers, then they can dismount them with ease, without having to use different types of equipment and without having to be extra careful.

Note that if the system is installed in a place that is difficult to reach or if there are any larger obstacles that cannot be moved, then the crew is going to take much more time.

Know that if you choose to hire specialists to get this done instead of you, the process will be done much faster, than if you have to do it on your own.

Type of replacement

The next thing that will affect this process is the type of replacement. If you are changing the old model of AC with the same exact one just a brand new one, then the process is going to go much faster. The crew can just come in, take the old unit out, and easily install the new one. This process should go pretty smoothly and there should not be any delays.

On the other hand, if you are interested in getting something extremely different, then there might be some complications. Know that every system needs to be connected with the second device that is placed outside, and this means that there should be openings or any type of connection between the outside device and the indoor one.

If the openings that are already in place are the right size, and if there is enough room for the new model, then this process should be relatively quick, but if there is the need for new openings, or making the old ones bigger or smaller, then it may take a few extra hours. Should you consider getting one, you consider engaging professional aircon installation companies.

How long will it take?

As you can see, there are a lot of things that are going to affect the process, and it is pretty difficult to speculate on the time without having any information about the units, the space, as well as other important details.

Other things that are going to affect the process include the number of people in the crew, their knowledge, as well as the state of the ACs that you already have. If the system is working properly, and if there are no damages, the whole thing should get done faster. However, if there were any leaks, if there is damage to the walls and the foundation, or if there are any pests or mold, you will first need to take care of that before you install the new devices.

The rule of thumb is that if everything is in perfect order, and if there is no need for other openings, cleaning, and if the units are accessible, the process should not take more than a few hours. However, if things turn out to be more complicated than you have planned, it may take the crew a day or two to get everything done.

If you want to know the exact time that this change is going to take, then you should just talk to your preferred service and ask them not only for a quote for the replacement but also ask if they can tell you how long it is going to take. More often than not, this is going to take less than one day, so you should not be worried that you are going to be left without your colling system during the hot days. If possible, get this thing done either before or after the cooling season, so that you don’t have to be left waiting for the new AC when you need it the most.
