PTAC Air Conditioner Review


As air conditioning challenges continue to evolve and develop as a real concern to stakeholders of various industries—from hospitality establishments to healthcare facilities, and even residential buildings—the quest to find the most effective cooling and heating system becomes more significant than ever. At the core of these basic concerns rest the need for a powerful, energy-efficient, and operationally flexible air conditioning system that ensures the best level of comfort and the highest amount of savings. Across many industries, you can’t overemphasize the significance of this endeavor. For hospitality businesses, for example, like hotels and lodgings of various sizes, it’s all about providing the maximum comfort for guests. For business offices, it’s about creating a perfectly conducive environment that can help spike productivity. For residential buildings, such as dorms, apartments, and condominiums, it’s about maximizing utilities while ensuring comfort for tenants. And for healthcare establishments, for instance, such as hospitals, clinics, and assisted living facilities, it’s about ensuring better patient care. For ordinary homeowners, it’s not just about comfort but about having complete control over that comfort as well. Indeed, air conditioning has long transitioned from being a luxurious tool into a type of equipment that essentially has far-reaching significance to our day-to-day life. Undoubtedly, there are many types of air conditioning systems, and each one seems to have been technologically upgraded over the years, effectively facilitating the introduction of better cooling and heating solutions for various sectors and industries. But despite this, there remains some situations when these systems—even the most commonly used and popular—can hardly keep up in terms of flexibility, performance, and efficiency to meet the needs in unique applications and environments. But there are always some exceptions. And when it comes to the need for proper and effective air conditioning in hospitality establishments, healthcare facilities, and residential buildings, this exception comes in the form of an excellent, powerful, and highly energy-efficient cooling and heating solution—the PTAC. 

What is PTAC?

PTAC stands for Packaged Terminal Air Conditioner. It is a self-contained or unitary heating and cooling system where its main components—the compressor, condenser, evaporator, and expansion valve, among others—are housed in a single casing.

Where are PTACs Used?

PTACs are commercial-grade systems, which means they are best for commercial use, although they can work as well in residential applications. As a system, you will find PTACs being used in many commercial establishments, institutional facilities, and even residential properties.

How Does PTAC Work?

During cooling operation, the refrigerant pumped by the compressor helps cool the coils. This allows the unit to absorb the heat and humidity from the room and exhaust them outside. When used for heating, the process is reversed. This time, the refrigerant helps heat the coils. The heat warms the air which is subsequently blown inside the room. Remember that for heating, PTACs either use a heat pump or an electric heat.

What Does a PTAC Unit Look Like?

PTAC's vary in sizes, but it has a standard width of 42 inches and are typically bigger than the normal through-the-wall air conditioner.

How is PTAC Installed?

PTACs are installed through a wall. During setup, the side of the unit where the conditioned air passes through is faced inside the room, while the other side where the ventilation happens and the exhaust air is released is faced outside. To install a PTAC unit, you need to cut a hole in the wall with the exact dimension needed to attach an external sleeve with an exterior grille. These will serve as support for the PTAC unit when you finally put the system into place. To place the PTAC unit, simply slide it through the hole where the sleeve is already fixed. Normally, the sleeve and the grille are sold separately from the unit, so you’d have to consider this fact when calculating your possible expenses. If you can’t do the installation yourself, you can always ask for a professional help from a licensed HVAC contractor. Also, take not that the place where you will install a PTAC unit should have a power outlet nearby for electrical connection.

What Makes PTAC Very Easy to Install?

Unlike ducted systems like central air, a PTAC system does not require ductwork. And compared with ductless systems, a PTAC unit has no need for refrigerant lines.

What are the Other Accessories Needed for the PTAC Unit Installation?

PTAC system installation also requires you to purchase and prepare other materials, such as wiring cables for the connection, drain kit, and remote controllers or thermostats if they are not included in the system package.

How Can You Know that PTAC is Your Best Option?

When it comes to air conditioning an average-sized room, you have a luxury of having too many choices. But as it happens, not every system is ideal for certain environments and conditions. There will be situations when most of the available and commonly used systems will very difficult to install, impractical to use, or just plain impossible to be applied to your specific space and situation. When this is the case, PTAC, as a cooling system for single rooms, will always be a good option. Upgrade Your PTAC Choice with Gree ETAC
