Enhancements to packaged terminal air conditioner technologies and designs continue to assist hoteliers in boosting guest comfort and cutting energy usage. Over the years, PTACs have grown from a cheap alternative that could heat or perfect space to highly efficient machines while still keeping the cost benefits and ease of maintenance associated with the devices.

“The efficiencies have not only improved on the cooling side but also on the heating side,” said Sabby Sabharwal, Friedrich’s product manager of specialty goods. “The heat pump units have a coefficient of performance of up to 3.6, helping save substantially on operational costs.” Units also have gotten more efficient and are quieter through design advancements, said Douglas Mackemer, director of parts, supplies, and specialist equipment at Carrier Enterprise. “I also think there is a greater knowledge of the correlation between unit maintenance and equipment performance, longevity and visitor comfort as well,” he said.

It’s agreed—not only is there increasing acknowledgment that the units work better when properly maintained, but the PTACs are becoming more service-friendly. This allows hotel employees to perform repairs rapidly.
A new, two-motor design with separate motors for the inside blower and the exterior fan has helped make the PTAC units quieter, Sabharwal said. The insulated indoor-outdoor partition compartment on the Friedrich PTAC units further helps in better sound attenuation.

Occupancy-sensing energy-management thermostats with built-in occupancy sensors are also aiding efficiency. When rooms are empty, smart thermostats automatically alter the temperature to prevent wasteful heating and air-conditioning, helping realize enormous savings on the electricity bills, Sabharwal added.

A remote administration website allows monitoring and tweaking of these energy-management thermostats from any computer, tablet, or smartphone connected to the internet. Wireless control offers additional flexibility and convenience for hoteliers, said Matt Conant, national sales manager of air conditioning products at ECR International.

Looking to the future, the experts foresee more of the same breakthroughs enhancing PTACs. The changes will contribute to enhanced guest comfort, experience, and pleasure. Conant said while variable speed compressors are already available in PTACs, he expects the technology to progress significantly within the next five years. He also anticipates sophisticated control capabilities such as occupancy sensors to advance PTAC technology further.

“We will not only discover ways to further increase the operating efficiencies of the units but we also can add features that will boost the overall value of the product category,” Sabharwal said.

What to Look for When Buying PTACs

Hoteliers should consider various aspects while purchasing new PTAC units. The experts believe that there are six crucial factors when buying a PTAC.


Are PTAC units energy-efficient? New PTAC models are substantially more energy-efficient than previous ones. With room heating and cooling costs contributing as much as 70 percent of a property’s energy costs, hoteliers should purchase models with a high-efficiency rating to decrease those costs.
Noise level\sLook for devices with low operational noise levels and high sound insulation is reflected by high sound transmission class and high outdoor-indoor transmission class ratings.


Two-fan systems, drain kits and remote thermostats are among technological improvements that hoteliers should consider when purchasing units.


The most crucial thing about a PTAC is that it runs consistently. A malfunctioning unit might render a room inoperable, resulting in income loss.


PTACs must be adequately maintained to operate efficiently, and new models make preventative maintenance activities even more accessible. The experts advise consumers to seek features such as easy access to the air filter. It’s quick to attach power connections and universal heaters.

Support for products

Additionally, experts agree that product assistance from the manufacturer is critical if necessary. How fast can the manufacturer address any product-related concerns? A non-operational unit results in revenue loss. “Are you getting everything you desire from that company?” inquired Conant.

The Use of New Technology has Enhanced Day-to-Day Operations.

First, hoteliers must select an efficient, dependable, and durable product. A responsible and durable product entails fewer problems when servicing the unit, Sabharwal explained. A certified third-party unit (Air Conditioning, Heating, and Refrigeration Institute) should instill trust in the unit’s operational efficiency.

Interfacing the units with property management systems enables equipment control. Additionally, it provides input on the operation and efficiency of the equipment, Mackemer explained. “Notification of underperforming equipment and issues to maintenance. As well as management before guests are aware of a potential performance issue,” he explained.

Conant concurred. “It is critical to monitor the equipment’s efficiency and anticipate future difficulties,” he explained.
Conant further stated that preventative maintenance has made PTACs much easier to maintain. “The equipment should be removed and cleaned every three months to twice a year,” he explained.

“I’ve seen four-year PTACs look worse than decade-old PTACs, simply because the decade-old ones were properly maintained,” Mackemer explained. “It is critical to maintaining proper cleaning and upkeep.”Additionally, experts agree that product assistance from the manufacturer is critical if necessary.
