Frequently Asked Questions
What does “BTU” mean, and how do I know what size I need?
BTU stands for British Thermal Unit and measures how much heat an AC can remove per hour. A good rule of thumb is 20 BTU per square foot. So, for a 300 sq ft room, you’d want around a 6,000 BTU AC. Check the product descriptions for coverage details; the DELLA 14K covers up to 700 sq. ft., for example.
Some of these ACs require professional installation. How much hassle is it to set up the Senville LETO or DELLA Versa?
Mini-split systems like the Senville LETO and DELLA Versa often require professional installation because they involve refrigerant lines. While it does add to the cost and require scheduling, professional installation ensures proper operation and maintains the warranty. The Senville LETO even includes professional installation in its price! The DELLA Versa needs professional vacuuming during installation.
The Dreo AC515S says “drainage-free.” Does that really mean I never have to empty any water?
Pretty much! The Dreo AC515S is designed to evaporate the condensation it collects. As long as the humidity is below 85%, you shouldn’t need to worry about draining it. If you live in a super humid place, you might have to drain it sometimes, but most users won’t have that issue.
What does “Smart” mean in the LG Smart Window AC and the DELLA 14K descriptions?
“Smart” usually means you can control the AC with your phone or voice assistants. The LG Smart Window AC works with Wi-Fi and voice control. This lets you adjust the temperature and settings from anywhere. The DELLA 14K features geo-location automation.
What’s the difference between the Senville LETO and the DELLA Versa, and which one is right for me?
Both are mini-split systems designed for year-round comfort. The Senville LETO packs a bigger punch (24,000 BTU) and is better able to work in even colder temperatures (-15°C). Also, it comes ready with professional installation and a five-year warranty. The DELLA Versa, on the other hand, is more energy-efficient and budget-friendly but may not be suitable for very large spaces or extreme cold. The Versa offers savings from the 19 SEER2 efficiency rating.
