7 Factors To Consider When Buying A PTAC


A Packaged Terminal Air Conditioner (PTAC) might be the ideal choice if you need an energy-efficient solution to cool and heat spaces without any ductwork. If you’re going to renovate an old house, outfit a guest room, or replace an existing model, a PTAC is the best option to ensure long-term comfort in any space.

Factors To Consider When Buying A PTAC

In most cases, PTAC units are popular in the hotel industry or houses that lack central air conditioning. These are space-saving appliances that provide both cooling and heating. As a ductless system, it works as a through-the-wall installation near the floor of the space with an external grille facing outside and the controls facing the room.


Choosing the suitable PTAC model for your space is crucial to ensure the best comfort and conserve energy at the same time. If you want to learn more about PTAC units and how to find the right one for your needs, you can click here.

Here are several important factors to consider when buying a PTAC.

  1. BTU Output

You should also determine the British Thermal Units or BTUs that your space requires by using a BTU calculator. The output of your ideal PTAC will depend on the area’s size where you’ll install it. Buying a unit with the appropriate BTU amount is essential to prevent the space from getting too humid.

Using a unit with a higher BTU isn’t a good idea since it can cause uncomfortable levels of humidity and affect the unit’s overall functionality. A PTAC unit that isn’t strong enough for space will utilize more energy than necessary, resulting in overstrain and shortening its lifespan.

  1. Price

If you want an energy-saving option to keep your home comfortable all year round, a PTAC unit is a good choice. Since it offers both cooling and heating, a packaged terminal air conditioner can help save on the yearly utility costs.

Remember, though, that PTAC units will cost more and need an external sleeve and grille, which isn’t part of the appliance’s cost. The wall sleeves hold the unit in place, while the grilles are primarily an aesthetic consideration. When replacing an old PTAC unit, you’re most likely to reuse the current sleeve and grille.

  1. Plug Types

When getting a new PTAC, you should carefully consider the plug type. There are three options for amperage when selecting a PTAC – 15-amp, 20-amp, and 30-amp.

You can plug in your PTAC unit or hard-wired to the wiring within the building. When selecting the location to install the unit, the plug type should correspond with the outlet you’ll use. If you are replacing an existing unit, inspect the chassis’ data plate to determine the amp draw and ensure that the plug matches the one already in place.

  1. EER And SEER Ratings

The Energy Efficiency Ratings (EER) and Seasonal Energy Efficiency Ratings (SEER) measure a unit’s overall energy efficiency. If the rating is high, the more energy-efficient it is. A PTAC typically displays EER.

  1. Two-Fan Systems

The PTAC units include either a one-fan or two-fan system. A two-fan system is quieter, with one fan on the condenser side and the other on the evaporator side.

If you want a peaceful system in your space, selecting the fan system is reliable since several popular brands all have the same noise levels. Although various PTAC brands in the market utilize data to distinguish the noise levels, they all use multiple testing standards, so there isn’t much continuity.

  1. Drain Kits

The drain kits include fittings, spouts, plus gaskets that connect to the base pan of the PTAC. Even though drain kits are unnecessary, they’re beneficial in diverting the excess condensate from leaking directly onto the ground.

The majority of the condensate moves back onto the coil to boost the efficiency level, but some are likely to seep out via the exterior grille on the unit’s rear. When a drain kit is present, you can utilize a hose to redirect any surplus moisture.

  1. Remote Thermostats

Although PTAC units include built-in thermostats, having a remote thermostat will offer convenience by allowing you to customize the space where you intend to install it.

In case the room is under construction, the thermostat wiring should be in place before the walls will be sealed. If you install a PTAC in an already built room, a wall-mounted thermostat is available and offered by the manufacturer.


If you’re eager to install a PTAC unit in your home or workplace, there are several factors to consider to ensure the best possible comfort for years to come. Depending on your specific needs, these factors will help you find a suitable model for your space in no time.
