Both Marriott International and Hilton Worldwide require PTAC units that meet standards for:

• Energy efficiency (EER/CEER ratings)

• Noise levels for guest comfort

• Heating and cooling capacity

• Reliability and serviceability

Brands may also require compatibility with energy management systems (EMS) to optimize energy usage.

Approved or commonly accepted manufacturers include hospitality-focused providers such as Amana and GE Appliances.

Choosing the wrong units can lead to guest complaints, higher operating costs, and potential compliance issues during inspections.
