Frequently Asked Questions About Ductless Mini Split Air Conditioners
Are ductless mini splits energy efficient?
Yes, ductless mini splits are among the most energy-efficient HVAC systems available, thanks to inverter technology and the elimination of heating or cooling loss common with ductwork.
Can ductless mini splits heat a home?
Yes, most modern mini split systems include built-in heat pumps, which are capable of providing heating during colder months. The temperature range a mini split can operate efficiently in may vary depending on the model and brand, but the Senville Aura Series Mini Splits are a great option that can efficiently heat in temperatures as low as -22 degrees F.
What size mini split do I need?
The size of the mini split that you need will depend on the room square footage, insulation, ceiling height, and climate. Most mini split product pages will state their coverage area in square footage, but our Mini Split Buying Guide walks through sizing considerations step-by-step.
Is 18 SEER or 20 SEER better?
SEER and SEER ratings are better as the number increases, so a 20 SEER-rated system is more efficient than an 18 SEER-rated system. A higher-rated SEER score lowers your long-term energy costs, but can cost more upfront. Sylvane’s “What's the Difference Between EER and SEER?” article further explains what SEER is and how it compares to other energy rating systems.
Are mini splits worth it for multiple rooms?
Yes, multi-zone mini splits are a good alternative to other ductable heating and cooling solutions. Mini splits like the Senville 36,000 BTU Quad Zone Mini Split Heat Pump with Wi-Fi are ideal for flexible, efficient comfort, allowing for more individual room temperature control. They are great for homes or offices that have different temperature requirements for individual rooms or for more energy savings by adjusting the temperature based on whether the room is occupied or not.
Which Mini Split is Right for Your Space?
No matter which ductless mini split AC you choose from this year’s top models, you’re investing in comfort, efficiency, and flexible climate control for your home or business.
