👋 Introduction: Why Noise Levels Matter for Savvy Homeowners
When choosing a heating and cooling system, performance and energy savings often take the spotlight. But for Savvy homeowners, sound matters too. Whether you're installing the MRCOOL Easy Pro in a nursery, home office, bedroom, or meditation room, a noisy mini split could be a daily distraction.
Luckily, the MRCOOL Easy Pro 12,000 BTU Mini Split was designed for whisper-quiet comfort. But just how quiet is it, really?
In this guide, we’ll cover:
-
Official indoor and outdoor decibel (dB) ratings
-
Real-world noise tests in different settings
-
Comparisons to common appliances

Tips to reduce noise even further
📊 MRCOOL Easy Pro Decibel Ratings: What the Specs Say
| Component | Noise Level (dB) | Notes |
|---|---|---|
| Indoor Unit | 23–38 dB (low to high) | Equivalent to whispering |
| Outdoor Condenser | 50–58 dB | Similar to rainfall or a fridge |
Understanding dB Levels:
Decibels are measured on a logarithmic scale, meaning a 10 dB increase equals 10x more noise energy. That’s why small-sounding differences matter.
| Sound Source | Approx. dB |
| Whisper (3 ft away) | 20–25 dB |
| Quiet library | 30–35 dB |
| Normal conversation | 60 dB |
| Vacuum cleaner | 70–75 dB |

🔧 How to Reduce Noise Even More
Even a whisper-quiet unit can get even quieter with smart setup and maintenance:
1. Proper Mounting
-
Use anti-vibration pads on wall brackets
-
Mount away from structural beams or vents
2. Keep Filters Clean
-
Dirty filters force fans to work harder = more noise
-
Clean every 30 days
3. Use Sleep Mode at Night
-
Slows fan + turns off display light
4. Clear Outdoor Obstructions
-
Keep unit at least 24" from shrubs or walls
-
Obstructions can echo sound back at you
