How to Choose Mini Splits
Cooling Capacity
Cooling capacity is measured in BTUs. A unit with 12,000 BTUs is commonly suitable for a room up to 550 square feet. Bigger areas need more cooling power. If your space exceeds this size, look for higher BTUs. A rule of thumb is to add 2,000 BTUs for each additional room.
Energy Efficiency Rating
Energy efficiency is measured by SEER ratings. Choose a unit with at least a SEER rating of 16 for better energy savings. Higher ratings mean more savings on your electric bill. A 20 SEER rating is excellent for energy conservation, especially for frequent use.
Ductless vs. Ducted
Ductless systems are easier to install and more efficient for cooling single rooms. Ducted systems cover larger areas but require more installation work. If you have multiple rooms to cool, a ducted system may be better, while a ductless system is great for individual rooms.
Heating Capability
Some mini splits also provide heating. Look for units that can heat down to at least 5°F, making them functional year-round. If you live in a cold climate, choose a model with reliable heating performance to ensure comfort in winter.
Noise Level
Mini splits are quieter than traditional window units. Check the noise level in decibels (dB) before buying. Aim for a model under 55 dB for peaceful operation. The quieter the unit, the better it is for bedrooms or offices.
