Buying Guide

What should you consider when selecting an inside A/C solution or cover?

  • Room size and cooling needs: For portable units, match BTU to room square footage. Larger rooms may require higher BTU or supplemental dehumidification.
  • Ventilation and installation: Portable units need a venting path; window adapters simplify setup. Inside covers require precise sizing to seal effectively.
  • Seasonal protection: Covers reduce dust and drafts but should be breathable and weather-appropriate to avoid moisture buildup.
  • Durability and material: Look for water-resistant fabrics for covers and corrosion-resistant hardware for mounts.
  • Vehicle compatibility: Automotive evaporator assemblies require proper integration with vehicle power and controls; consult a professional if unsure.
  • Safety and compatibility: Always confirm window types (sliding, double-hung, casement) and weight limits for any mount or bracket.
