Guestrooms that include PTACs have some basic constraints that every designer and owner should know.

The hotel introduced 15 new Pure rooms, which create an allergy-friendly environment and are said to remove up to 98 percent of bacteria and viruses.

Six months after an international environmental agreement deadline, new PTAC units that run on an alternative refrigerant, R-410A, are gaining solid footing in the industry.

Guestroom technology constantly evolves and changes. But since the '60s, the PTAC has been the staple heating-and-cooling system. Will there ever be a successor?

PTACs are usually the best option in the guestroom, but certain projects may benefit from a different strategy.

As tough as it is to calculate true utility bill savings after installing an energy-management system, those hoteliers who have done so say there is no doubt that installing a system has a direct impact on reducing PTAC runtime.

Last week, La Quinta offered some members of the media a peek behind the curtain, so to speak--an opportunity to observe one of the company's brand council meetings. The council, which meets at least three times per year, includes corporate executives and franchisees.

The owners and operators of Denver’s first hotel, The Oxford Hotel, recently completed upgrades on the building that improve energy efficiency while decreasing average monthly utility costs by 47 percent.

PTACs and HVACs should be treated similarly to how a person treats a car. Every 3,000 miles you change the oil and perform proper engine maintenance to keep the car operating efficiently—the same care must go into air conditioning your hotel.

A new regulation in the heating and cooling industry will have a Casablanca-like effect on hoteliers. Maybe not today, maybe not tomorrow—but sometime, the units at your hotel will have to be updated to a new, environmentally friendly refrigerant.
