MRCOOL DIY System: Included Components & Installation Must-Haves

What’s Included with Your MRCOOL 4th Gen DIY System

Applies To: DIY Series

When someone orders a MRCOOL DIY system, they’re not just getting a box—they're getting the whole package (minus a few tools and electrical odds and ends). Our kits are built to empower homeowners to install their systems confidently, without calling in a pro. Here’s what comes in the box, what extra gear they might need, and the tools required to get the job done.

📦 What’s in the Box?

Every MRCOOL DIY system includes a thoughtfully packed set of components to make setup as smooth as possible:

• Indoor Air Handler Unit: This is the sleek piece that goes on the wall inside the home, quietly circulating clean, conditioned air. It houses the fan, filters, and control system.

• Outdoor Condensing Unit: The hardworking outdoor unit does all the heavy lifting when it comes to cooling and heating. It’s built to withstand the elements and deliver consistent performance all year long.

• Pre-Charged Line Set: No need to handle refrigerant—our line sets come pre-charged and ready to connect. Just hook it up and go.

• Remote Control: Because comfort should be convenient. Adjust temps and settings from across the room with ease.

• WiFi Dongle: Download the app, pair your unit, and control it from your phone—whether you’re home or not. Total climate control in your pocket.

• Communication Cable: Keeps the indoor and outdoor units in sync so everything runs smoothly.

• Mounting Plate & Template: Helps nail the perfect placement for the indoor unit and gives it a secure base.

• Hardware Kit: Screws, bolts, brackets—everything you need to hold things together.

• Remote Control Holder: No more digging through the couch cushions. Mount this holder and give your remote a proper home.

• Allen Wrench: You’ll need this to open refrigerant valves during install. We’ve got you covered.

• Neoprene & Insulating Material: Keeps things efficient and protected from the elements.

• Sound Dampening Pads: Shhh—comfort shouldn’t come with a side of noise. These help keep things quiet.

• UV Tape: Protects refrigerant lines from the sun’s harsh rays, helping extend the life of your system.

• Wall Sleeve: Creates a clean, sealed path through the wall for your line set.

• Drain Hose: Helps route condensate safely away from the unit—no drips, no mold, no problem.

➕ A Few Extras You Might Need

While we try to include just about everything, here are a few extras the customer may need to grab depending on their setup:

• Wiring/Disconnect: For connecting the system to their electrical panel.

• Extra Drain Line: If they need a longer run than what’s provided.

• Mounting Bracket: For those who want to lift the outdoor unit off the ground.

• Line Guard: To neatly conceal and protect refrigerant lines.

• Local Code Items: Like float switches or surge protection—these vary based on local building codes, so it’s good to double-check.
