An air conditioner is one of the most crucial pieces of equipment in a home or office, and one common question that clients ask before installing a new one or replacing an old one is, how long does it take to install an AC unit? Normally, it takes 4–8 hours to get a system up and running, but the total time frame varies based on the factors below.
Size of the Home
One crucial factor determining how long it takes to install an air conditioner is the square footage of the home. Experts conduct home inspections before commencing work because they must check the square footage and the amount of work needed for the electrical wiring and ductwork. Usually, the larger the size, the longer it will take.
Unit Placement
Where the HVAC system will be installed also factors in. If the location of the new unit is not easily accessible, it means that the experts will need more time for installation. This will also come up during the assessment of the home’s condition as they figure out the best location for the unit.
Type of Unit
The unit type also determines how long it takes to install AC. There are various types of air conditioning units, each featuring a unique design, and of course, they are installed differently. For instance, if you need split units, each with its individual components that go indoors and outdoors, instead of a packaged unit, it will take the professionals more time.
Size of the Unit
When conducting routine inspections, the technician will perform load calculations to help determine the perfect size of air conditioning for the space. This is the best way to ensure that the system to be installed will be efficient. If you need a larger AC, it will take the experts more time to set it up.

Replacement or First Time?
Do you need a new AC unit or want a replacement? Installing a new AC unit will take more time. It means new wiring and ductwork installation, which will require more work. However, if it is a replacement, the infrastructure already exists, so unlike a first-time installation, it won’t need as much time.
