This 50 ft insulated copper AC line set (3/8" x 1-1/8") is designed for select 3–5 ton air conditioning and heat pump systems that require a larger suction line. It’s ideal for high-capacity residential or light commercial HVAC applications where proper refrigerant return is critical.
If you're searching for a professional-grade AC line set that supports peak system performance, this model delivers superior flow capacity, energy efficiency, and durability. It’s a top choice for contractors and property owners who need a reliable solution for larger HVAC systems.
Who installs the AC unit after I purchase it?
ACDirect does not yet provide installation services directly. However, most of our customers successfully arrange installation through local licensed HVAC contractors. These systems are designed for professional installation and typically include the components your installer will need.
Here’s how it works:
Note:
Please be aware if you choose to install HVAC equipment yourself and don’t possess proper HVAC licensing, you will void the manufacturer’s factory warranty. If you are capable of a factory-compliant installation yourself, you will need a licensed HVAC contractor to sign off on your work, fully confirming factory-compliant workmanship.
