Factors Affecting How Long It Takes to Install an Air Conditioner
When you are trying to estimate how long it will take to install an AC, there are a number of factors that impact the time it takes. The size of the system, the current system you have, the type of system you decide on all matter. Where you want the system to be installed also plays a part in this, as it could be on the roof or on the side of your home.
We’ll get a little deeper into each aspect here:
Size of Your Home
The time it takes to install an air conditioning unit can vary depending on the size of your home. Square footage and home size are essential factors, as they affect the time needed for the in-home estimate and initial inspection. Larger homes may require more time for the installation of a central air conditioning unit, as well as additional time to address complication factors such as ductwork modifications and electrical issues.
Location of the Unit
The installation location plays a significant role in the time needed to install an air conditioner. If the location is difficult to access, this may extend the installation time. During the in-home estimate, the technician will assess the home condition and determine the best location for the central air unit, taking into consideration the indoor evaporator coil, outdoor condenser, and line set.

Type of AC Unit
Different types of air conditioning units, such as mini split units, packaged units, and condensing units, may require different installation times. For instance, split units have separate indoor and outdoor components, while packaged units combine these components into one.This difference in design can affect the time needed for installation.
Size of Unit
The size of the AC system, including the outdoor condenser and indoor evaporator coil, also impacts the installation time. Larger systems may require more time to install the line set, connect the refrigerant, and ensure proper functioning. During the in-home estimate, the technician will perform a manual load calculation to determine the appropriate size of the air conditioning unit for your home, ensuring optimal performance and efficiency.
Whether You Need Ductwork or Not
Ductwork modifications can significantly impact the installation time. If your home needs new or updated ductwork, expect the process to take longer than a standard installation. This might involve EPA regulations regarding asbestos removal in older homes. If your home already has ductwork in place that needs no adjustments, it’s a time saver.
Replacement Or First-Time Installation
A changeout, or AC unit replacement, may require less time than a first-time installation. Existing infrastructure, like wiring and ductwork, can expedite the process. However, any additional work, such as disconnecting and wiring an air conditioner to a furnace, could add time.
How Long Does It Take To Replace An AC Unit?
Replacing an AC unit usually takes less time than a new installation. HVAC contractors are familiar with the process and can efficiently remove the old unit, capture refrigerant, and install the new system.
How Long Does It Take to Install Central Air Vs. A Mini Split?
Central air installation typically takes longer than split units due to the complexity of the ductwork and wiring. Mini splits are quicker to install since they don’t require ductwork. In both cases, system commissioning is essential to ensure optimal performance and energy efficiency.
What To Expect On the Day Of An AC Installation
On the day of your AC installation, you as the customer should expect the contractor to have everything handled. The most work you should have to do is clearing around the space your system will be placed, removing personal items and anything you may not want in the way. From there, the contractor should be able to take the wheel!
HVAC Professional Preparation
On the day of the AC installation, an HVAC professional will arrive at your home to start the process. They will lay drop cloths to protect your flooring and assess the current system for the best removal method.
Brazing and Wiring
The HVAC contractor will remove the old system, and then connect the new outdoor unit to the indoor unit. This involves brazing the line set with nitrogen to create an airtight seal free of contaminants. Wiring is crucial for the AC to communicate with the rest of the HVAC system and seamlessly switch between heating and cooling, and communicate with the thermostat.
Thermostats and Crawl Spaces
The HVAC professional will also ensure that your thermostat is compatible with the new system. They may need to access crawl spaces or other hard-to-reach areas for wiring and ductwork modifications.
Furniture Dismantling and Air Filter Replacement
In some cases, furniture dismantling may be necessary to provide ample space for the installation. After the installation, the technician will recommend regular air filter replacement to maintain your system’s efficiency and avoid strain on the unit.
Maintenance, Utility Bills, and HVAC Contractors
To keep your HVAC system running smoothly and avoid higher utility bills, schedule yearly maintenance with a professional. This not only preserves your warranty but also ensures the best performance from your HVAC system, and the most longevity for your system.
