How Long Does AC Installation Take? What Homeowners Should Expect

If you are planning an AC installation in Phoenix, one of the first questions that probably comes to mind is simple: how long is this going to take?

It is a fair question. Living in Arizona without a working air conditioner is not just uncomfortable. It can feel like you are slowly melting into your own couch. When summer temperatures climb well above 100 degrees, timing matters.


The truth is that most residential ac installation projects can be completed in one day. However, the exact timeline depends on several factors, including the size of your home, the condition of your existing system, and whether any upgrades are needed. In this guide, we will walk you through what to expect before, during, and after installation so you can plan with confidence.


Let’s break it down step by step.

Average AC Installation Timeline: What Is Typical for Most Homes?

For many homeowners, a standard ac installation takes between 4 and 8 hours. In straightforward situations, your new system can be up and running before dinner. But that is only if everything goes smoothly.


Here is what a typical installation day might look like:

1. Removal of the Old System

If you are replacing an existing unit, the team will first disconnect and remove the old equipment. This includes the outdoor condenser, indoor air handler or furnace coil, and refrigerant lines if needed. This process usually takes 1 to 2 hours.

2. Preparing the Installation Area

Technicians inspect the pad or mounting surface outside and the indoor space where the new equipment will sit. Minor adjustments, leveling, or modifications may be needed to ensure everything is secure and up to code.

3. Installing the New AC Unit

This is the core of the ac installation process. The team sets the outdoor condenser, installs the indoor evaporator coil, connects refrigerant lines, and wires the system. This stage typically takes several hours.

4. System Testing and Calibration

Once installed, the system is vacuumed, charged with refrigerant, and tested. Technicians check airflow, thermostat communication, and temperature output to make sure everything is operating properly.



In ideal conditions, the entire process can be completed in a single workday. That means you are not stuck without cooling overnight.


However, certain situations can extend the timeline.

Factors That Can Affect How Long AC Installation Takes

Not all homes are the same, and not all installations are simple replacements. Several factors can influence how long your ac installation will take.


Size of the Home

Larger homes typically require larger systems or more complex setups. If ductwork spans multiple levels or zones, installation can take longer.

Condition of Existing Ductwork

If your ducts are leaking, undersized, or damaged, repairs or modifications may be necessary before the new system is installed. Ductwork upgrades can add several hours or even an additional day to the project.

Electrical Upgrades

Older homes may not have the proper electrical capacity for modern high efficiency systems. If a panel upgrade or new circuit is needed, this can increase the timeline.

Switching System Types

If you are switching from one system type to another, such as from a traditional central unit to a ductless system, the installation process can be more involved.

Permit and Inspection Requirements

In Phoenix, certain installations require permits and inspections. While much of this happens behind the scenes, scheduling inspections can sometimes impact overall timing.


The key takeaway is this: while most ac installation projects are completed in a day, complex situations may require additional time. A professional assessment will give you a clearer picture.

What Happens Before Installation Day?

Many homeowners focus only on the day of installation, but preparation plays a big role in how smoothly things go.


In Home Evaluation

A professional technician should perform a detailed evaluation before recommending a system. This may include:

  • Measuring square footage
  • Evaluating insulation levels
  • Checking ductwork condition
  • Performing a load calculation to determine proper system size

This step is critical. An oversized or undersized unit can cause efficiency problems, uneven cooling, and premature wear.


System Selection

Once your home is evaluated, you will choose a system that fits your needs and budget. Efficiency ratings, features, and warranty coverage all come into play.


Scheduling

Once the system is selected and ordered, installation is scheduled. During peak summer months in Phoenix, availability can fill up quickly. Planning ahead can help you avoid emergency situations where you are scrambling for last minute service.


Preparing your home ahead of time also helps. Clearing access to indoor equipment areas and ensuring pets are secured will make the process faster and safer.

What to Expect on Installation Day

Installation day might feel a little chaotic at first. There will be tools, equipment, and technicians moving in and out of your home. But a well organized team makes the process efficient and professional.


Here is what you can typically expect:

Arrival and Setup

The team will arrive with your new system and necessary tools. They will lay down protective coverings to keep floors clean and safe.

Removal of Old Equipment

Old equipment is carefully disconnected and removed. Refrigerant is handled according to environmental regulations.

Installation and Connections

The new system is installed, connected to electrical components, and tied into ductwork. Refrigerant lines are sealed and insulated.

Testing and Walkthrough

After the system is powered on, technicians test performance and verify airflow. You should receive a walkthrough explaining thermostat operation, maintenance tips, and warranty details.


A professional ac installation should leave your home as clean as it was before the team arrived. If anything feels rushed or incomplete, it is okay to ask questions.
