Is It Possible to Relocate an AC Line Set If Needed?

Table of Contents

When it comes to installing or moving air conditioning units, one of the critical components to consider is the AC line set. These sets of copper pipes carry refrigerant between the indoor and outdoor units, playing a vital role in the cooling process. But what if you need to relocate them for various reasons? Is it possible to do so without compromising the efficiency and performance of your air conditioning system? Let’s explore this question further.

What Is an AC Line?

Before discussing relocation, it’s essential to understand what an AC line set is. The AC line set consists of two copper pipes – a smaller, insulated one called the liquid line and a larger one known as the suction line. These pipes transport refrigerant between the indoor evaporator coil and the outdoor condensing unit, facilitating the heat exchange process that allows your air conditioner to cool your home.

Is It Possible to Relocate an AC Line Set?

Relocating an AC line set is indeed possible, but it’s a task best left to HVAC professionals. It involves several steps and considerations to ensure the proper functioning of your air conditioning system.


A professional technician will thoroughly assess the new location for the AC line set. This assessment involves considering factors like the length of the new run, potential obstacles, and environmental conditions such as exposure to sunlight or extreme temperatures.

By carefully evaluating these factors, the technician can determine the most suitable route for the line set and anticipate any challenges that may arise during the relocation process. Additionally, they will assess the electrical requirements and ensure that the new location meets local building codes and regulations.


Depending on the specifics of the new location, the technician may need to reroute the line set to avoid obstacles or accommodate the desired placement of the indoor and outdoor units. This could involve adjusting the path of the line set, installing new piping, or making modifications to existing structures to create a clear pathway for the lines. The technician will take into account factors like the optimal placement for efficient airflow, accessibility for future maintenance, and aesthetic considerations if the lines are visible.

Refrigerant Handling

Handling refrigerants requires specialized expertise and equipment to ensure safety and prevent environmental harm. During the relocation process, the technician will carefully recover any existing refrigerant from the system using approved recovery equipment. This step is crucial for preventing the release of harmful substances into the atmosphere.

Once the line set has been relocated, the technician will recharge the system with the necessary amount of refrigerant to guarantee optimal performance. They will also check for any leaks in the system and repair them before recharging.

Sealing and Insulation

Proper sealing and insulation of the line set are important for maintaining energy efficiency and preventing heat loss or gain. The technician will ensure that all connections between piping sections are securely sealed to prevent leaks. Additionally, they will install insulation around the piping to minimize heat transfer and sustain the desired temperature within the system. Effective insulation not only enhances energy efficiency but also helps prevent condensation and corrosion, prolonging the lifespan of the components.


After relocating the line set, the entire AC system must undergo comprehensive testing to verify its performance and efficiency. This testing process may include pressure testing the lines to check for leaks, verifying that the refrigerant levels are within the manufacturer’s specifications, and testing the system’s overall functionality to guarantee it operates effectively in its new configuration.

The technician will also conduct airflow measurements to ensure proper ventilation and temperature distribution throughout the space. By thoroughly testing the system, the technician can identify any issues and make any necessary adjustments to ensure optimal performance and reliability.


Is it necessary to relocate an AC line set?

Relocating an AC line set may be necessary in situations where the current placement doesn’t meet practical or aesthetic requirements. For instance, if you’re remodeling your home and need to move the indoor or outdoor unit, relocating the line set becomes essential.

Can I relocate an AC line set by myself?

It’s not recommended to relocate an AC line set without proper training and expertise. Handling refrigerant and making adjustments to the system requires specialized knowledge and equipment. It’s advisable to hire a professional HVAC technician to ensure the job is done safely and correctly.

Can an AC line be repaired?

In some cases, depending on the nature and severity of the damage, there are instances where an AC line can undergo repair instead of replacement. Small leaks or minor damage to the line set may be repairable using specialized techniques such as brazing or soldering. However, extensive damage, corrosion, or deterioration may warrant the replacement of the entire line set to guarantee long-term reliability and performance.

Will relocating the line set affect the performance of my AC system?

When done properly by a qualified technician, relocating the line set should not significantly affect the performance of your AC system. However, it’s crucial to make sure that the new location is suitable and that proper procedures are followed during the relocation process to maintain optimal performance.

How can I find a reliable HVAC technician to relocate my AC line set?

Look for licensed and experienced HVAC contractors in your area. Seek recommendations from friends, family, or neighbors, and research online reviews. Be sure to verify the contractor’s credentials, insurance coverage, and warranty offerings before hiring them for the job.


While relocating an AC line set is possible, it’s a task that should be entrusted to experienced HVAC professionals. With their expertise, they can ensure that the relocation is done safely and efficiently, preserving the performance and longevity of your air conditioning system.
