Buying Guide for Mini Splits for 1000 Sq Ft Garages
When selecting a mini split system for your 1000 sq ft garage, here are key factors to consider for optimal comfort and efficiency:
1. BTU Capacity and Coverage
Choose a system around 16500 to 18000 BTU to effectively cool and heat a garage of 1000 sq ft. Undersized units may not maintain desired temperatures, while oversized units can short cycle, reducing efficiency.
2. Heating Performance in Low Temperatures
If you live in a cold climate, prioritize mini splits with heat pump capabilities that function well below freezing (below 20°F). Models like DELLA Hyper Heat that operate down to -13°F provide reliable winter heating.
3. Energy Efficiency Ratings
Devices with higher SEER2 ratings (19 or above) and features like DC inverter technology offer better energy savings, leading to lower electric bills. Look for certified products by ETL, AHRI, or Energy Star.
4. Refrigerant Type
Modern units using R32 refrigerant are preferred for environmental concerns as they have lower global warming potential compared to older types like R410A.
5. Installation Requirements
Professional installation is generally recommended, especially for line-set adjustments and refrigerant charging. Check if the system includes a full installation kit with copper piping and drain lines.
6. Smart Features and Controls
Look for WiFi-enabled mini splits with app or voice control compatibility (Amazon Alexa) for convenient remote operation. Additional features like 4D airflow, sleep mode, and timers enhance comfort and control.
7. Noise Levels
Garage mini splits should operate quietly to avoid disturbance. Units with noise ratings around 50 dBa or lower are ideal for residential or hobby garages.
By evaluating these attributes based on your climate, garage size, and comfort preferences, you can select the best mini split system tailored for your garage’s unique requirements.
