PTAC or PTHP? Breaking Down the Differences

The Packaged Terminal Air Conditioner known in the industry as simply PTAC is the most common type of through the wall heating and air conditioner system used in hotel guest rooms. The choices are clear. PTACs are completely self contained with no refrigerant line or outdoor compressor required. They are individually controlled by the guest with limits set by the hotel staff to conserve energy. The PTAC is the most affordable year round heating and cooling system you can find in the HVAC industry. The premium version of a PTAC is known as the Packaged Terminal Heat Pump or PTHP. A PTHP works just as a PTAC does however it has a built in "Heat Pump". Heat pumps as many know are served better in warmer climates where the outside temperature does not dip below freezing. A Heat Pump is very energy efficient because it reduces the cost of running electric heat however Heat Pumps in general do not perform well in colder climates because it needs a certain amount of warm outside air to efficiently heat the room. What makes the PTHP so special is that unlike conventional heat pumps these models have a built in electric resistance heater which automatically kicks in when the heat pump can no longer do the job. So whether the outside temperature is 45 degrees or 5 degrees the PTHP is always on the job. The cost difference between a PTAC and PTHP is minimal (about $50-$75) but certainly a smart choice when you consider the cost saving benefit.
