Wall Mounting 101: Best Locations for Your MRCOOL Easy Pro Indoor Unit

0 comments

When you install a MRCOOL DIY Easy Pro mini split, the indoor wall-mounted unit is the star of the show. It’s sleek, quiet, and delivers heating and cooling where you need it most. But here’s the catch: if you mount it in the wrong spot, you won’t get the comfort or efficiency you paid for.

Many first-time DIYers make the mistake of treating placement as an afterthought. In reality, the difference between a perfectly mounted unit and a poorly placed one can mean:

Uneven temperatures in the room
Higher energy bills
Noisy or drafty airflow
Extra wear on the system

This guide breaks down everything you need to know about choosing the right wall location for your MRCOOL Easy Pro indoor unit, with practical tips for different rooms and layouts.

📏 Step 1: Mounting Height

The height of your mini split unit matters more than you think.

✅ The Sweet Spot

Mount 7–8 feet above the floor.
Leave 6–12 inches of clearance above the unit and at least 6 inches on each side.

⚠️ What Happens If It’s Too Low?

Airflow gets blocked by furniture.
Cooling feels drafty because it blows directly at you.
Temperature readings can be inaccurate.

⚠️ What Happens If It’s Too High?

Heat accumulates near the ceiling, so the system works harder.
Uneven temperatures in the lower part of the room.

🌬️ Step 2: Airflow & Circulation

The goal of placement is to maximize circulation across the whole room.

Tips for Better Airflow

Point airflow toward the center of the room.
Avoid corners, alcoves, or recesses that trap air.
For rectangular rooms, mount on the shorter wall so air travels across the length.

Example:

Mark installed his Easy Pro in his basement rec room. By mounting it on the shorter wall facing the open space, the cool air traveled evenly across the room. A friend who mounted his unit in a corner? He had hot spots on the far side of the room.

🚪 Step 3: Avoid Obstructions

Your MRCOOL Easy Pro needs clear air paths to function properly.

Keep 3+ feet clear in front of the unit.
Don’t mount above wardrobes, tall bookshelves, or cabinets.
Avoid drapes, blinds, or wall décor that can block airflow.

👉 Pro tip from Mark: Think ahead about how you’ll use the room in the future. Don’t mount above a wall where you might later add shelving or a big screen TV.

🧊 Step 4: Stay Away from Heat Sources

Mini splits rely on a thermistor sensor in the indoor unit to measure room temperature. If the unit is mounted near heat, it will misread the room’s true temperature.

Places to Avoid:

Direct sunlight (especially west-facing walls).
Above stoves, ovens, or radiators.
Near televisions or gaming consoles.

Instead, mount on a neutral wall away from heat fluctuations.

🔇 Step 5: Noise Considerations

MRCOOL Easy Pro units are quiet, but placement still matters.

Don’t mount directly above your bed — even gentle airflow can disrupt sleep.
Avoid corners where sound can echo and amplify.
If you work from home, mount away from desks for a quieter Zoom call experience.

Mark’s tip: “In bedrooms, mount opposite the bed. In living rooms, avoid blowing directly at couches.”

🌡️ Step 6: Room-Specific Mounting Strategies

Every room has unique challenges. Here’s how to get it right:

🛋️ Living Room

Best: Center wall facing open space.
Avoid: Above TV or electronics.

🛏️ Bedroom

Best: Wall opposite the bed.
Avoid: Direct airflow at the bed.

🧰 Garage or Workshop

Best: Longest open wall with few obstacles.
Ensure clearance from tools, shelves, or vehicles.

🏢 Home Office

Best: Behind your chair or to the side, not in front of your desk.
Avoid: Direct airflow at your computer setup.

🏠 Open-Concept Rooms

Best: Mount where air can travel across the widest span.
If space is over 1,000 sq. ft., consider a larger BTU unit or multiple zones.

📖 Comfort standards from ASHRAE explain why air distribution matters.

🛠️ Step 7: Indoor-to-Outdoor Line Set Path

The MRCOOL Easy Pro is a DIY system with pre-charged line sets. This means planning the line set run is crucial.

Pick a wall that allows a short, direct line set exit to the outdoor condenser.
Avoid running lines through multiple walls if possible.
Keep the drain line sloped downward to prevent leaks.

👉 Mark’s advice: “Measure twice, drill once. A good line set path makes the install cleaner and faster.”

🚫 Step 8: Common Placement Mistakes

❌ Mounting inside alcoves or closets.
❌ Above doors and windows (draft interference).
❌ On weak walls without solid framing.
❌ Ignoring furniture layout — airflow ends up blocked later.
