Planning Your MrCool DIY Installation

Before you even open the box, proper planning is crucial for a successful MrCool DIY installation. This ensures a smooth process and avoids costly mistakes.

1. Assess Your Space and Needs

Room Size: Determine the square footage of the room you're cooling or heating. MrCool offers various BTU sizes; choose one appropriate for your space. Using their BTU calculator on their website is highly recommended.
Electrical Requirements: Confirm you have the necessary electrical capacity. Your MrCool unit will require a dedicated circuit. Check your breaker box and consult a qualified electrician if unsure.
Wall Considerations: Ensure your chosen wall can support the weight of the indoor and outdoor units. Also consider the distance between the units and any obstacles that might hinder the refrigerant line installation.
Refrigerant Line Length: MrCool units have a maximum refrigerant line length. Measure carefully to ensure your chosen location falls within this limit. Exceeding the limit could affect performance or void the warranty.

2. Gather Your Tools

Having the right tools on hand will significantly speed up the installation process and prevent delays. You'll need:

Level: Essential for ensuring proper unit alignment.
Drill with various drill bits: For drilling holes for the refrigerant lines and electrical wiring.
Vacuum Pump: Crucial for evacuating air and moisture from the refrigerant lines. (Renting is an option if you don't own one.)
Refrigerant Line Cutting and flaring tools: For precise cutting and flaring of the copper refrigerant lines.
Wrench set: For tightening connections.
Wire strippers and crimpers: For electrical connections.
Measuring tape: For accurate measurements.
Safety Glasses and Gloves: Always prioritize safety!

3. Check Your MrCool DIY Kit Contents

Carefully inspect the contents of your MrCool DIY kit against the packing list. Contact MrCool customer support immediately if anything is missing or damaged. This proactive step prevents delays.
