Buying Guide: Key Factors to Consider When Choosing a Mini Split for Your Home
Cooling and Heating Capacity
Assess the size of the area you wish to heat or cool. Mini splits come in various BTU ratings. For small rooms (up to 400 sq. ft.), 9000 BTU is typically sufficient, while larger spaces up to 750 sq. ft. benefit from 12000 BTU units or higher.
Energy Efficiency Ratings
Look for mini splits with a high SEER (Seasonal Energy Efficiency Ratio) rating. Models with 17 SEER2 or above offer better energy savings. Inverter technology further optimizes compressor speed for consistent temperature control and lower electricity use.
Heating Capability
If year-round comfort is important, choose mini splits with integrated heat pumps. These units efficiently switch between heating and cooling modes, providing reliable warmth in colder months.
Noise Level
Consider models with low operational noise, especially for bedrooms or quiet spaces. Units operating around or below 28 decibels help maintain a tranquil environment.
Additional Features
- Smart Controls: WiFi-enabled mini splits offer remote operation via smartphones or voice assistants.
- Multiple Modes: Auto, dry, fan, turbo, eco, and sleep modes enhance comfort and convenience.
- Installation Kit Included: Buying a unit with a complete installation kit can simplify setup and reduce additional costs.
Environmental Considerations
Newer refrigerants such as R32 are more environmentally friendly and recommended to minimize ecological impact. Confirm the type of refrigerant used for eco-conscious purchasing.
Mounting and Installation Accessories
Ensure you select appropriate wall mounting brackets and line set covers for a neat and secure installation. Accessories made from durable, weather-resistant materials help maintain system longevity outdoors.
