Buying Guide for Gas Mini Split Systems
BTU Capacity and Room Size
Choosing the correct BTU rating is essential for effective cooling and heating. Smaller rooms typically require 9,000 to 12,000 BTUs, while larger spaces may need systems rated 18,000 BTU or more. Oversizing or undersizing can affect comfort and energy efficiency.
Energy Efficiency Ratings
Look for systems with a high SEER2 (Seasonal Energy Efficiency Ratio) and HSPF2 (Heating Seasonal Performance Factor). Higher ratings indicate more efficient use of energy, leading to lower electric bills. Many top mini splits use inverter technology for improved efficiency and quieter operation.
Installation and Kits
Some mini splits come with full installation kits, including copper piping and mounting hardware, which simplify setup. DIY-friendly models also reduce costs and installation complexity. Verify whether you need professional installation or can install the system yourself.
Heating Capabilities and Climate Suitability
For colder climates, consider units with strong heat pump performance and capabilities to operate efficiently at low temperatures. Features like automatic defrosting are beneficial in snowy or freezing environments.
Smart Features and Controls
WiFi connectivity and compatibility with smart home assistants like Alexa offer remote control and convenience. Timer settings, multiple fan speeds, sleep modes, and silent operation modes enhance usability and comfort.
Noise Level
Assess the noise output, especially for bedrooms or quiet areas. Most modern mini splits operate quietly below 50 decibels, ensuring they do not disrupt daily activities or sleep.
Environmental Considerations
Choose systems using eco-friendly refrigerants like R32 and with energy-saving modes to reduce environmental impact. Certifications like ETL and AHRI guarantee safety and efficiency compliance standards.
