  • Smart Features and Controls: WiFi connectivity, voice assistant compatibility (Alexa, Google), mobile app control, and programmable timers increase convenience and energy savings.
  • Installation Kit and Support: Models with a comprehensive installation kit (including copper piping and drain tubing) simplify setup. Verify what is included beforehand.
  • Operating Noise Level: Quiet operation (below 30 dB) is important for bedrooms or workspaces to ensure minimal disruptions.
  • Durability and Certifications: Look for AHRI and ETL certifications to ensure reliability, safety, and performance standards.
  • Climate Suitability: Some units can operate in very cold environments (-4°F or lower). Choose based on your local climate for optimum performance.
