Summer is here, so now is the perfect time to talk about PTACs! When people purchase PTACs they often think that a more powerful unit with more BTUs is better. It should cool the room faster, and you will never have guests complain, right? Unfortunately, no. Although this misconception is common, oversizing PTAC units in hotel rooms can be a major problem for a number of reasons. 

1. Oversizing PTAC units can lead to discomfort for guests. If a PTAC unit is too large for a room, it can cool or heat the space too quickly, leading to uneven temperature fluctuations that can be uncomfortable for guests. 
2. If a PTAC unit is too large for a room, it may not be able to effectively dehumidify the air, leading to an increase in moisture levels in the room. This can lead to the growth of mold and other harmful substances, which can be dangerous for guests and can also damage the hotel's structure.
3. If a PTAC unit is too large for a room, it will do something called "short-cycling". This is where the unit will cycle on and off more often than it should due to uneven cooling of the room. This can be financially detrimental for hoteliers, who may struggle to keep up with the increased energy costs. In addition, oversizing PTAC units can lead to more frequent breakdowns and other issues, which can be costly to repair and can cause disruptions for guests.
4. Furthermore, oversizing PTAC units can be dangerous for the environment. If a PTAC unit is too large for a room, it will use more energy than necessary to cool or heat the space, leading to a negative impact on the environment.

So please remember when you are purchasing your next batch of PTACs that oversizing PTAC units in hotel rooms can be bad for you, your guests, and the environment. Hoteliers who take the time to properly size their PTAC units can avoid these dangers and provide a safer, more comfortable experience for their guests, and their bottom line.
