⭐⭐⭐⭐⭐ James Carter - Hotel Operations Manager
"We installed the Gree Advanced Model duct AC units across 12 guest suites last April, and they’ve been flawless. The variable frequency inverter technology keeps room temperatures perfectly stable, even during peak summer. Guests consistently comment on how quiet the units are—much quieter than our previous system. Installation was faster than expected thanks to the modular design."Purchase Date: April 2024 | Usage Period: 8 months
⭐⭐⭐⭐⭐ Elena Martinez - Office Facility Coordinator
"Our open-plan office in Lisbon needed a reliable, low-noise climate solution. We chose the Gree Pro Model for its SEER 18 efficiency and 32 dB(A) noise level—and it’s made a noticeable difference. Energy bills dropped by nearly 25% compared to last year, and employees no longer complain about AC noise disrupting calls. The R410a refrigerant also helped us meet our corporate sustainability targets."Purchase Date: June 2025 | Usage Period: 3 months
⭐⭐⭐⭐☆ David Lin - Homeowner
"Installed the Base Model in our newly renovated apartment in July. It blends seamlessly into the ceiling, and the custom duct compatibility allowed our contractor to work around existing beams. The cooling is consistent, and I appreciate the eco-friendly refrigerant. Only reason I didn’t give 5 stars is that the remote interface feels a bit outdated—but functionally, it’s excellent."Purchase Date: July 2024 | Usage Period: 7 months
⭐⭐⭐⭐⭐ Dr. Anita Patel - Clinic Director
"We needed a discreet, quiet AC system for our outpatient clinic. The Gree ducted unit operates so silently that patients don’t even notice it. The RoHS and CE certifications gave us confidence in safety compliance, and the metal grille has held up well to frequent cleaning. Maintenance is minimal, which is a big plus for our small staff."Purchase Date: February 2025 | Usage Period: 5 months
⭐⭐⭐⭐☆ Marcus Johnson - Boutique Retail Owner
"Used the Advanced Model in my 800 sq ft store. The adjustable airflow direction lets me cool the display area without blasting customers at the entrance. Energy savings are real—I’m seeing about 30% less on my monthly HVAC costs. Only downside is the initial cost, but I expect it to pay off within two years."Purchase Date: November 2024 | Usage Period: 10 months
