Your Guide To What NOT To Do During
A Ductless Mini-Split Installation

Do you have rooms in your home where you just can’t ever seem to get the temperature right? Investing in a mini-split installation in Grand Rapids, Michigan might be the best solution.

These systems enable you to create customized climate zones in key areas of your home for maximum comfort and reduced energy consumption. However, to ensure you reap all the benefits a mini-split system has to offer, you’ll want to avoid several installation mistakes.

At SULLIVAN Heating Cooling Plumbing, we want your installation to be as stress-free as a day at the Downtown Market. So, we break down all the missteps to avoid, from DIY installations to incorrect placement.


Mistake #1: Incorrect Placement During
Your Mini-Split Installation

The placement of your new mini-split system is more than just a matter of aesthetics – where you position the indoor and outdoor units matters for both efficiency and functionality. When the system is placed correctly, you’ll enjoy reduced energy consumption and optimized airflow.

So, where should your new system go?

For optimal results, position your indoor unit 6–8 feet above the floor, allowing sufficient space around it. This allows for even distribution of the air throughout the entire room.

The outdoor unit must be placed on solid ground or securely attached to an exterior wall. In either location, you’ll need to plan for enough space around the unit to allow for proper airflow and prevent overheating.


Mistake #2: Choosing The Wrong Size Mini-Split Setup

You’ve probably heard the saying, ‘Bigger isn’t always better.’ Well, that’s also true when it comes to your new mini-split system.

One of the most common mistakes homeowners make is choosing a system that’s too large for their space. While it may seem that a larger system will cool a room more efficiently, that’s not always the case.

Oversized units tend to cycle frequently, which means you’ll spend a lot more money on your energy bills than you expected. On the other hand, if your mini-split system is too small, it’ll have to work twice as hard to maintain the correct temperature in your room.

Choosing the proper size setup for your heating and cooling needs is essential.



Mistake #3: Not Insulating Your New Mini-Split System

Insulation is a crucial component of any heating and cooling system. You cannot maximize the efficiency of your mini-split system without it.

Refrigerant lines must be adequately insulated to prevent costly energy loss. In addition, electrical components require their own insulation to keep you and your equipment safe.

Skipping this step during the installation of your new system can result in uncomfortable temperature fluctuations and reduced overall efficiency.

You’ll also need to ensure that the room where you install your mini-split has adequate insulation. This enables the system to maintain steady, even temperatures with reduced runtime. Your system will function more efficiently and last longer.


Mistake #4: Improperly Wiring Your
Kent County, MI Mini-Split Setup

A mini-split system isn’t your average electrical appliance – it has different requirements that must be met for optimal system efficiency and safety.

Each mini-split system has specific current and voltage ratings that must not be exceeded. Additionally, these systems are sensitive to voltage fluctuations. Mistakes in wiring can lead to overheating and constantly tripped breakers.

You’ll also want to consider the overall aesthetic appeal of your new system. No homeowner wants a jumbled-up mess of wires hanging from their mini-split system.

Partnering with a factory-trained HVAC technician is crucial to guaranteeing your family’s safety and ensuring your new system is barely noticeable.


Mistake #5: Attempting A DIY Mini-Split Installation

There are a ton of videos on YouTube that explain how to do pretty much anything, including installing your own mini-split system. The problem? Not everything is meant for an afternoon DIY project.

Not only does this project involve electrical risks, but it also requires handling refrigerant. Accidents can be catastrophic and costly.

From crooked mounts to inadequate airflow, the problems that can arise from installing your own system are nearly limitless. So, why not skip them altogether and hire a team of professionals like us at SULLIVAN?
