A successful installation begins with a high-quality Line Set, which connects the indoor and outdoor components of your Single-Zone System. We provide several lengths of Insulated Copper Line Sets, often featuring a Flare Nut Connection for a secure, leak-free seal. For the ultimate ease of use, our DIY Mini Split collection features Quick-Connect Line Sets that are pre-charged with refrigerant. You will also need a Disconnect Box and an electrical Whip to safely provide power to the outdoor condenser. To protect your equipment from voltage spikes, we highly recommend adding an HVAC Surge Protector to your order. The Communication Wire (14/4) is included in many of our Installation Kits to ensure the indoor and outdoor units talk to each other correctly. To keep the exterior of your home looking sharp, a Decorative Line Cover (Slimduct) can be used to hide the pipes. Don't forget a Condenser Pad or Mounting Bracket to keep your unit level and off the ground.
