Unboxing and Installing the Ductless Air 24,000 BTU Mini Split System: A Comprehensive Guide

Hey everyone, welcome back to the channel! Today, we’re diving into a comprehensive unboxing of the 24,000 BTU Ductless Air Mini Split system that I’ll be installing in my woodshop. This guide aims to explore the intricacies of the unit, compare it to other DIY options, and provide insights into its installation and functionality.

Introduction to Mini Split Systems

Mini split systems provide a valuable option for heating and cooling smaller spaces, bringing efficiency and convenience to residential and commercial applications. Unlike traditional HVAC systems, mini splits come in a compact, user-friendly package that can be perfect for workshops, additional rooms, or even entire homes.

What Makes Mini Splits Unique?

1. Independent Zoning: Each indoor unit operates independently, allowing precise control over different areas.
2. Energy Efficiency: With high SEER (Seasonal Energy Efficiency Ratio) ratings, these units are exceptionally efficient, reducing operational costs.
3. Installation Flexibility: Mini splits can be installed in various locations and require no ductwork, making them ideal for retrofitting scenarios.

Overview of the Ductless Air 24,000 BTU Mini Split System

Specifications

• BTU Rating: 24,000
• SEER Rating: 21
• Line Set Length: 25 feet
• Main Components: Outdoor unit, indoor unit, line set, control wires, and various accessories

Price Comparison

I purchased this unit on sale at Home Depot for $1300, whereas a similar DIY-friendly 24,000 BTU Mr. Cool system would cost around $2000. The main difference lies in the pre-evacuated line set, which the DIY set includes but my unit does not. This article will discuss whether the cost-saving trade-off is worth it.

Unboxing the Ductless Air Mini Split System

The Outdoor Unit

Upon unboxing, I noticed the outdoor unit is quite sizable, a sign of its robust 24,000 BTU capacity. The unit’s build quality seemed solid, featuring a service panel on one side and connections for the line set and electrical wiring.

Additional Accessories Found:

• 6-foot drain hose (Note: I needed to purchase a longer hose for my setup)
• Rubber pads for mounting

The Indoor Unit

The indoor unit was larger than expected, but its clean, streamlined design and quality build were impressive. The package included instructions, a remote control, mounting hardware, and some brass fittings.

Control Wires & Accessories

In the accessory boxes, we found the essential control wires that connect the indoor and outdoor units. Alongside these, there was a wall sleeve and protective cover for the line set penetration, a few rolls of tape, and sealing clay.

Line Set

The 25-foot line set comprises a 3/8-inch and a 5/8-inch pipe, pre-configured with ends. While you may not need a flaring kit, trimming the lines might be necessary to maintain a neat installation.

Preparing for Installation

Tools and Materials Required

• Vacuum pump and gauge set (a setup can be found on Amazon for under $150)
• Longer drain hose (if needed)
• Basic tools for mounting and connection
• Electrical wiring tools
• Protective gear

Pre-Installation Considerations

1. Placement: Consider the best location for both the indoor and outdoor units. Ensure adequate airflow around them and easy access for maintenance.
2. Separation and Airflow: For spaces like my woodshop that have divided sections, additional fans might be required to ensure consistent airflow between sections.
3. Power Supply: Ensure your electrical system can handle the load of the new unit.

Installation Procedure

Mounting the Indoor Unit

1. Wall Preparation: Mark the spots for mounting the bracket and drilling for the line set and control wires.
2. Bracket Installation: Secure the mounting bracket firmly to the wall.
3. Line Set and Wires: Guide the line set and control wires through the wall sleeve, ensuring they’re well-protected and sealed with the provided sealing clay.

Mounting the Outdoor Unit

1. Pad Placement: Position the rubber pads where the unit will rest, providing stability and reducing vibrations.
2. Unit Positioning: Place the outdoor unit on the pads, ensuring it stays level and has the required clearances for airflow.

Connecting the Line Set

1. Pipe Connection: Securely attach the line set to both the indoor and outdoor units, trimming if necessary for a neater fit.
2. Vacuuming the Line Set: Use the vacuum pump and gauge set to evacuate air and moisture from the line set. This step is crucial for efficient operation.

Electrical Connections

1. Control Wiring: Connect the control wires according to the provided schematics, ensuring they run from the indoor to the outdoor units correctly.
2. Power Supply: Connect the power supply to the outdoor unit, following safety standards and local codes.

Testing the Mini Split System

Initial Power-Up

With everything connected, it’s time to power up the unit and check for proper operation. Monitor the system for the following:

• Cooling and Heating Efficiency: Ensure the unit reaches the set temperatures within a reasonable time.
• Airflow: Check the distribution of air in all parts of the space.
• Noise Levels: Listen for any unusual noises during operation, which could signify issues with installation or the unit itself.

Troubleshooting

If the system does not function as expected:

• Verify Connections: Double-check all electrical and line set connections.
• Check For Leaks: Ensure there are no refrigerant leaks in the line set connections.
• Review Instructions: Revisit the installation manual to make sure no steps were missed.

Comparison to DIY Units

As mentioned earlier, the DIY Mr. Cool system comes with a pre-evacuated line set, simplifying the installation process but at a higher cost. While the non-DIY unit I chose requires extra steps, such as vacuuming the line set, it ultimately provides the same functionality with significant cost savings if you already own or can purchase a vacuum pump affordably.

Cost Analysis

• Ductless Air System: $1300 + $150 (vacuum pump) = $1450 approximately
• Mr. Cool DIY System: $2000 approximately

Effort vs. Savings

While the Mr. Cool system offers convenience, those comfortable with basic HVAC tasks might find the $700 savings worthwhile. The added effort of vacuuming the line set is minimal if you are equipped with the proper tools and follow instructions carefully.
