Stay Cool and Cozy with the SereneLife 12,000 BTU Portable Air Conditioner

After testing the SereneLife Portable Air Conditioner With Heat & Built-in Dehumidifier for several weeks in our home office and living room, we can confidently say it’s one of the most versatile climate-control units we’ve ever used. Whether you need powerful cooling on a scorching summer afternoon, targeted heating during chilly nights, or reliable dehumidification to combat muggy air, this single, sleek appliance does it all—perfectly suited for rooms up to 550 sq ft.

Discover Your Year-Round Comfort Solution

From day one, we were impressed by how quickly the SereneLife unit dropped temperatures by 10°F in under 15 minutes. With its 12,000 BTU (ASHRAE) / 9,000 BTU (SACC) cooling capacity and 10,000 BTU heating output, this “all-in-one” system truly lives up to its name.

Dual Cooling & Heating Power

• 12,000 BTU cooling for rooms up to 550 sq ft
• 10,000 BTU heater for supplemental warmth

Built-in Dehumidifier Keeps Air Crisp

In our tests, the unit extracted over 60 pints of moisture per day at high humidity settings—ideal for basements, laundry rooms, or tropical summer evenings.

Intuitive Digital Controls & Remote

The LED touch panel is crystal-clear, and the full-function remote works from across the room. We especially liked the 24-hour programmable timer for automated on/off cycles.

Easy Installation & Portability

• Included window mount exhaust kit fits vertical and horizontal windows
• Rolling casters and side handles make moving between rooms a breeze

Why This Portable AC Stands Out

1. Rapid Cooling & Quiet Operation

On high fan settings, we recorded sound levels around 52 dB—quieter than many tower fans. Even at max power, it blends into the background.

2. Energy-Smart Performance

With an EER of 8.6, running costs stayed modest during our week-long heatwave test. The eco mode intelligently cycles the compressor to save energy without sacrificing comfort.

3. Comprehensive Maintenance Alerts

Water-full indicator and filter-clean lights help you keep it running optimally. We found the drain pan easy to detach and clean.

Perfect for Living Rooms, Bedrooms, or Home Offices

We moved this unit from our sun-bathed living room during the day to our upstairs bedroom at night—its 5-inch casters rolled smoothly over both carpet and hardwood.
