How to Choose the Best PTAC Units

Not all PTAC units are created equal, and in reality, not all of them will work well for every building. To help you find the best match for your needs, let’s take a closer look at factors to consider while shopping.

Your Region

One of the best ways to initially narrow down your search is to consider where you live. In short, are you in an area where it’s hot all year round? On the contrary, do you need your unit to act as a heating system as well?

If you live in a region with four seasons, you’ll unquestionably want to look at units that offer heating and cooling. On the other hand, if you happen to live in the south where the weather is rarely chilly, you can likely save money by purchasing a one that only offers cooling functionality.

Assuming you intend to use the PTAC as a primary heat source, you should concentrate your search particularly on units which have an electric heat pump.

Room Size

Before you start shopping for a unit, determine the square footage of the room you’ll use it in.

Your square-footage will explicitly determine how many BTUs the unit needs to efficiently cool or heat the space. In essence, the larger the room, the more BTUs you need. However, you may also need to purchase a higher BTU unit if the room experiences more extreme temperatures.

To summarize, purchasing the right level of power for your space will ensure you have an efficient unit that creates a comfortable environment all year long.

Noise Level

Some units generate more noise than others, so it’s smart to look into reviews and get a sense of how much noise it will add to your space, especially if you’re a light sleeper or spend your day talking on the phone.


You’ll also need to know the voltage of your unit. If you’re shopping for a home unit, the voltage will be 208/230, simultaneously, if you’re shopping for a commercial space, your unit may be 265/277 volt.

Amps and Electrical Cords

Above all, check your electrical panel to determine how many amps your unit needs. It will always be either 15, 20, or 30 amps.

The amps also affect what type of power cord your unit will have, although many manufacturers allow you to specify the type of cord you need when you make your purchase.

The Cost

Certainly, the cost of the unit will play a part in your decision, and how much you pay depends on a number of different factors, including the type of unit you choose and how powerful it is. You’ll also need to factor the cost of accessories like an external grill and a wall sleeve into the total purchase price.

When determining the cost, keep the energy use in mind. PTAC units use a considerable amount of energy to function, and consequently that cost can add up if you’re using the unit daily. While energy-efficient models generally cost more upfront, the long-term savings may make it worth your while.

Unit Durability and Available Warranties

When you invest in a PTAC unit, it’s important to make sure your purchase will stand the test of time. After all, you plan to rely on it to keep you comfortable. Take your time to read customer reviews, and likewise, investigate how long the manufacturer guarantees the unit through warranties.

If you’re searching for an affordable option while protected by a warranty, explore refurbished PTAC units. These warranty-backed units are professionally restored by industry experts, thus offering you the opportunity to get a high-quality product at a great value.

Final Thoughts

Purchasing a PTAC unit for your home or building is a simple, and undeniably a smart way to create an ideal environment in any room. No matter where you live or what your needs are, there’s surely a unit fit for your needs.
