How Long Will It Take To Replace An AC Unit?

Replacing an AC unit in your Northern California home can be a complicated and risky process, especially if you do not have any experience with a task of this nature. It’s critical to note that this process can take between one and two days to complete, but in some cases may take longer. It all depends on several factors, such as your skill and experience in this arena, the type and size of your AC system, the complexity of the installation, and the availability of the necessary parts and tools.

A skilled technician will typically install an air conditioner in less than a day. The average installation time is usually somewhere between 4 and 8 hours.

Steps for AC Replacement

Here are the steps involved in replacing an AC unit:

  • Get a new AC system that fits your space and budget. You can do this by visiting a local hardware store or looking online. Ensure that you have all the necessary measurements, such as height and width, to find the right size unit for your home or business.
  • Contact a licensed contractor to install your AC unit. The contractor will be able to determine whether any structural changes need to be made to accommodate the new system properly.
  • Disconnect all power sources before beginning work on your new system by shutting off all circuit breakers in your home's electrical panel or flipping off the main circuit breakers in your home's fuse box.
  • Prepare the installation site following the manufacturer's directions to install the new unit. Also, ensure that there are no obstacles present.
  • Next step involves the installation of the new system. Professional installation will ensure that the new unit is properly secured to the mounting bracket, connected to necessary lines, and tested to confirm it's working correctly.

Factors Affecting the Time Taken to Replace an AC Unit

Size of the AC

The size of the AC unit is one of the most significant factors that will impact the time it takes to replace it. The larger the unit, the more time, effort, and skill are required to install it. This is because large units are typically installed outside the home or in a basement or attic space, which means they are heavier and harder to move. Conversely, a smaller system can be installed more quickly than a larger one because it weighs less, takes up less space, and requires fewer tools to move.

Type of AC

The type of AC unit you have will also impact the length of the replacement process. Some units, such as window units, are relatively easy to replace, while central air conditioning systems can be more complex and time-consuming. To fully understand the length of the replacement process for your particular AC system, you will need to consult with your contractor about what needs to be done and how long it might take to complete. In addition, make sure you are prepared for the expense of replacing an AC unit.

Age of the AC

Older units are likely built with older technology and require more work during their removal and installation processes than newer ones. This typically means that they are made with more parts that must be removed, cleaned, and replaced with a new system. This adds time to the entire process.
