Buying Guide for the Best Ductless Mini Split for Garages
When selecting a ductless mini split for your garage, it’s important to consider a range of factors to ensure the unit meets your specific needs. Here are key aspects to evaluate:
1. Cooling and Heating Capacity
Calculate your garage’s square footage to select a unit with adequate BTU capacity. Garages from 400 to 750 square feet commonly require 9000 to 12000 BTU mini splits. Proper sizing is critical for effective temperature regulation and energy efficiency.
2. Energy Efficiency and SEER Ratings
SEER (Seasonal Energy Efficiency Ratio) ratings reflect overall energy efficiency. Higher SEER numbers translate to lower electricity consumption and savings over time. Choosing models with inverter technology and SEER ratings above 17 is advisable for garages.
3. Heating Features
The presence of a heat pump allows both heating and cooling, essential for year-round garage comfort. Check operating temperature ranges for cold climates if your garage is exposed to extreme weather.
4. Noise Levels
Since garages may be used for hobbies or work, quieter units (below 40 decibels) are preferable to minimize disturbances.
5. Smart Controls and Connectivity
Wifi connectivity, remote controls, and voice assistant compatibility (Alexa, Google Assistant) improve user convenience. Some units offer advanced health features like air filtration and dehumidification.
6. Installation and Included Accessories
Many mini splits come with pre-charged condensers and installation kits. Ensure you have or arrange professional installation, especially for refrigerant line connections and electrical work.
7. Certifications and Warranty
Look for AHRI and ETL certifications which assure safety, reliability, and efficiency compliance. Warranty coverage adds protection and peace of mind.
