What does PTAC stands for?
An example of PTAC unit in Manhattan
PTAC air conditioners (packaged terminal air conditioners, abbreviated PTAC) are autonomous heating and air conditioning unit systems.
Often used in hotels, hospitals, condominiums and apartment buildings. PTACs - standard window or wall air conditioners - are suitable for in-wall installations. Each unit has ventilation holes and radiators both inside and outside.
What makes PTAC different from commercial ACs?
Unlike other systems, PTAC units consume refrigerant alternately to efficiently cool and heat room spaces. Large commercial ACs consist of separate sections: the condenser and evaporator are located at a large distance from each other. PTAC combines parts within one unit, which is usually mounted through an external wall.
What is inside a PTAC unit?
The interior of the PTAC unit consists of an evaporator coil, filters, fans, and air conditioning controls. The piping, compressor, condenser, and fan are located on the external surface of the device.
How does a PTAC air conditioner work?
Depending on the model, the PTAC unit can perform cooling or cooling and heating. It is designed to meet the specific goals of a single room and is powered by electricity.
Condensate from the air through a fan enters the heat exchanger, where it completely evaporates
PTAC units operate in hot and harsh climates, malfunction, do not like sudden changes in temperature, and require good ventilation.
How long does PTAC usually last?
The average lifespan is 7 to 10 years, if unit is well-maintained.
If following happens your PTAC unit isn't working properly
When your PTAC spits water, there must have been a problem with the position of the unit, which can be adjusted. It should be level or tilted slightly to the outside to drain properly.
When a unit fails to cool or heat a room as wanted, it may need a new thermostat or refrigerant, particularly if it is more than 5 years old.
Before you take any step, check if there is anything that blocks the front of the AC and limits the airflow, like furniture or curtains.
Change PTAC filters
Check the filter every month, clean or replace it if it has lint build up. A filter is much less expensive than a repair.
