Buying Guide: How to Choose the Best Mini Split for a 1200 Sq Ft Garage
When selecting a mini split air conditioner for a large garage around 1200 square feet, consider these critical factors:
- Capacity (BTU Rating): For a 1200 sq ft garage, units with at least 18,000 to 24,000 BTU of cooling and heating power are recommended. Higher BTU ratings ensure efficient temperature control for larger spaces.
- Energy Efficiency (SEER Rating): Look for units with SEER ratings above 17 for lower electric bills. High SEER2 ratings (19-20) mean better efficiency and energy savings.
- Voltage Requirements: Confirm your garage’s electrical supply supports the mini split’s voltage (typically 208-230V for higher-capacity models, 110-120V for compact units).
- Heat Pump Capability: Choose models with heat pumps to provide both cooling and heating, useful for garages in climates with cold winters.
- Smart Features: WiFi and Alexa compatibility allow remote control and scheduling, increasing convenience and energy management.
- Installation Needs: Larger units may require professional installation due to refrigerant charging and line-set adjustments. Check if the package includes copper lines and drain pipe kits.
- Airflow Control: Features like 4D airflow (up, down, left, right) help uniformly condition the garage space.
- Environmental Impact: Refrigerants like R32 offer improved air quality and lower environmental harm compared to older types.
For a 1200 sq ft garage, investing in a higher BTU unit with advanced inverter technology and smart controls will provide the best combination of comfort, efficiency, and ease of use. Consider multiple indoor units or multi-zone systems if you have subdivided or multi-use garage spaces.
