Buying Guide

  • Room size and BTU: Match the unit’s cooling and heating capacity to the space. Hotels typically target 20–30 BTU per square foot for climate control, adjusting for ceiling height and occupant load.
  • Unit type decisions: PTACs are ideal for wall-mounted hotel rooms with integrated heating, remote management, and multiple control options. Window and through-the-wall units offer cost-effective alternatives but may reduce window views and guest room flexibility.
  • Energy efficiency: Look for inverter or variable-speed technology and Energy Star-rated models to reduce energy consumption over time.
  • Electrical requirements and installation: Verify voltage (115V, 230/208V), circuit requirements, and whether a sleeve, grille, or wall installation kit is needed. Some units include these accessories; others require separate purchases.
  • Control and smart features: Wireless kits, app control, and compatibility with Alexa/Google Assistant can streamline guest experiences and housekeeping operations.
  • Maintenance and air quality: Consider units with washable filters, accessible components, and straightforward maintenance routines to ensure consistent performance in busy properties.
  • Quiet operation: Especially important for guest rooms; review dB ratings and fan speeds to minimize disruption.
