You’ve chosen the perfect AC unit to keep your home cool; but how long does it take to install the AC? While some installations seem to drag on for days, others are done in just hours. What’s the real story? Let’s break down the timeline, uncover the factors at play, and help you plan for a seamless installation experience.
Factors Affecting Installation Time
Different factors are the main reason the installation time varies so much. Before jumping into how long does it take to install air conditioner, let’s go through the factors that affect this period quickly.
Type of AC Unit
Different AC types and unit sizes impact how long it will take for the AC to be installed. For example, installing a central air conditioning unit takes more time than installing a mini-split AC. Similarly, multiple units take considerably more time than installing a traditional single-unit cooling system.
Property Size
A larger property or residence generally requires more time for ductwork installation and system configuration. As a result, the property needs a longer AC installation duration. The cost also increases for these extra works.
Existing Infrastructure
New houses without any existing infrastructure need everything installed from scratch. This includes installing the ductwork, exhaust line, and ventilation. Because of this, it’ll lengthen the installation duration.
Besides, upgrading your outdated system will consume more time than an empty set-up place.
Accessibility
When there is no ease of access to the air conditioning installation site, it can delay the procedure. Limited space or hard-to-reach locations can also extend the installation time.
Permitting and Regulations
Permits and regulations exist for homeowners’ safety, and efficiency, and to comply with building codes. However, applying for it takes time. An inspector needs to take time for the approval. There are potential delays and additional costs too for corrections.
Timeline Breakdown: Step-by-Step Installation Process
Usually, the installation of the machine takes a few hours to complete. However, there are many steps involved in the process that can add more time to the overall.
This is an overview of the whole AC installation process with time requirements for each step:
Pre-Installation Assessment (1-2 hours)
This is the crucial first step for a smooth AC installation process. First, a qualified HVAC technician visits the place to:
- Assess cooling needs
- Inspect existing infrastructure
- Discuss options
- Take measurements
- Provide estimates
After this assessment, the technician recommends the required AC size for your house and needs.
Equipment Preparation (1-2 Hours)
This step can take place in either the installer’s workshop or on-site.
The first step is to unpack and check for any shipping damage. The necessary components include refrigerant lines, wiring, mounting brackets, etc.
This stage also includes assembling minor components and checking the refrigerant charging time (whether pre-charged or required during installation).
Some additional tools are provided by the HVAC company you hire. Otherwise, it can take up some more time to gather them. You can skip this additional time with providers like Green Leaf Air.
Ductwork and Electrical Preparation (2-4 hours)
After unpacking, the next preparation step is to check your infrastructure. Professionals check the ductwork’s quality (existence of leaks, blockages, or damage) and the modifications necessary at this stage.
Different AC units have different electrical requirements. Technicians check for the load capability of your existing system in comparison to the AC.
Installation of AC Unit (4-8 hours)
This is the core of the installation. All the pre-works come together at this stage. Most people also count only this section as the “installation time”. It requires 4-8 hours.
This installation phase includes:
- Indoor unit installation
- Outdoor unit installation
- Connecting refrigerant lines
- Connecting electrical lines with both indoor and outdoor units
- Installation of condensate drain lines
Testing and Calibration (1-2 hours)
If the AC unit isn’t pre-charged with refrigerant, the technician adds it at this stage. After all of the installations are over, he checks for:
- Proper airflow
- Cooling performance
- Thermostat operation
In case it is not performing optimally, some further calibration and adjustments take place.
Final Inspection and Cleanup (1-2 hours)
After going through all the steps above, the technician performs a final inspection of the system. This step confirms that everything is installed correctly and meets the code requirements.
The technician then walks you through the operation of the system and the procedure to perform basic maintenance. You will also receive all necessary documentation and permit information.
How Long Does It Really Take to Install A New AC?
In the previous section, we covered time lengths for different stages of the AC installation process. But what would be the whole AC setup duration?
The average time to install an AC unit would be between 4 to 8 hours.
With the preparations, testing, and cleanup, it may take from 10 hours to a couple of days. As mentioned earlier, there are different factors at play that affect this timespan. If your home and ductwork are prepared with the unit, which is most often the case, it takes 4 hours plus the time for testing.
Timeframes Based on AC Type
When people talk about average time to install an “AC”, they mostly refer to split or central air conditioning systems. Because these systems require somewhat more complex installations. There are different components for different types of units hence the difference in the installation time.
Here is a comparison of just the installation time about different AC types:
| AC Type | Installation Time | Notes |
| Window AC | 30 mins – 1 hour | These units just require mounting and securing the unit on the window. |
| Split AC | 2-5 hours | Requires:
|
| Central AC | 4-8 hours (or more) | Requires:
Involves some additional process that can take up more of the time. |
Keep in mind, this is the time required for just the air conditioner without any modification to your household like ductwork or electrical connections.
Preparing for AC Installation
After hiring the HVAC contractor for AC installation, you’ll have to complete the following steps to make the project successful:
Step 1: Clear the installation area
Relocate objects or clutter in the installation area and surroundings. This will streamline the air conditioning process.
Step 2: Discuss installation preferences
If you have any specific preferences regarding the placement of the AC unit, the thermostat location, and other details, communicate clearly with the HVAC contractor.
Step 3: Schedule installation during off-peak times
HVAC contractors are more available during off-peak times like winter. They can dedicate more time to your project instead of just getting it “done”.
Step 4: Have a contingency plan
While AC installation typically doesn’t cause significant disruption, it’s still advised that you plan accordingly. Inform all your family members and neighbors about the upcoming AC installation and make all the necessary adjustments to accommodate the installation project.
Things to Keep in Mind
According to experts, always follow some “general rules” for a successful AC installation project:
- Proper sizing is paramount. Both oversized and undersized units have their shortcomings and perform poorly.
- Ductwork matters for central AC. Leaky ductwork can waste up to 30% of cooled air.
- Proper placement of outdoor and indoor units as well as the thermostats is key for maximizing efficiency.
- Look for units with higher SEER ratings for higher efficiency.
- Always monitor and perform a post-installation check before wrapping up the installation process.
Conclusion
AC installation times vary depending on different factors. The type of AC unit, the size of the property, site accessibility, and existing infrastructure – all play an important part in the duration. While most installations take approximately four to eight hours, complex projects or issues with permits and tool availability can extend the process to several days.
