Keystone KSTAP14A Portable AC Review

Keystone KSTAP14A Portable AC ReviewOne of the very best deals right now in a more powerful model is the Keystone KSTAP14A 14,000 BTU 115-Volt Portable Air Conditioner with “Follow Me” LCD Remote Control. However, there is a ton of misinformation out there concerning this model, which can make appreciating the true value of this air conditioner difficult. Here we take a closer look at the KSTAP14A and clear up some confusion that exists to help give you a better idea of what you are actually buying.

Keystone KSTAP14A – Key Specifications & Features

Great Power and Coverage Area

While this unit is often described as a 14,000 BTU model – in reality it is a 13,500 BTU portable air conditioner. We are not sure how this mis-characterization started, but there you have it. In reality though, this should not make too much of a difference for most users. Instead of the 700 square foot coverage area we normally associate with 14,000 BTU models, we’d suggest using this in a room no larger than 650 square feet. As usual though, coverage area depends more on the particular features of your room. For instance, high ceilings and large sunny windows will significantly reduce coverage area; whereas, well-insulated rooms with small or dimly-lit windows not facing a southern exposure will maximize coverage area.

Outstanding Energy Efficiency Ratio

This is the biggest source of confusion on the web today concerning this model, which is only made worse by other review sites that just copy and paste the error. In case you don’t know, Energy Efficiency Ratios (“EERs”) are the standard way for comparing electrical efficiency between models. EERs are simply calculated by dividing total BTUs by total wattage. Anything around an EER of 10.0 is very good, with higher scores being even better. Most models fall somewhere between 8.5 and 10.5 in our experience.

Somehow, an apparent (and very ironic) error occurred when setting up this model’s product description, and an EER of 2.67 was published. But this is obviously wrong! You must do the math!

The total BTUs of this model are 13,500, which, when divided by the unit’s total wattage (1,125 watts) gives you an EER of 12.0! So not only did someone mess up – the did so badly.

The true 12.0 EER Keystone KSTAP14A is actually quite extraordinary, meaning that this model is extremely efficient. In fact, this is one of the highest EERs we’ve seen for any portable air conditioner!

Single Hose Exhaust System

Portable units come in two types, single or dual exhaust systems. Single hose systems are more common, less expensive and a bit more simple to set up. Dual hose systems are more expensive and have somewhat bulkier window kits (b/c of the dual hose) but are more inherently efficient than single hose models – all other things being equal of course. This is because a dual hose unit sucks up and uses outside air to cool off the compressor, rather than using indoor air as single hose unit necessarily must.

However, as we’ve expained before, exhaust design is not the end of the story. A single-hose model with a high EER can still be very efficient, and in this case this unit’s phenomenal EER of 12.0 easily mitigates the slight efficiency loss associated with the single exhaust.

The Keystone KSTAP14A "Follow Me" remote control.“Follow Me” LCD Remote Control

Most portable air conditioners come with a decent remote, but the Keystone KSTAP14A uses one that also comes with a temperature sensor that uses the temperature of the remote’s location (rather than the unit’s) to determine room temperature. This is great, since your armchair may be in a warmer or cooler spot than the actual air conditioner. A very smart feature that we really wish more models used!

Self-Evaporating Condensate System

The Keystone KSTAP14A does not contain a drainage bucket because it uses a self-evaporating system that blows off the moisture as it accumulates so you shouldn’t have to worry about any condensate buildup under most conditions. This is a nice feature that eliminates the need to constantly check to see if a drain pan is full.

Other Nice Features

Beyond coming with good power, outrageous energy efficiency and a high-tech remote, this portable unit is nicely appointed with other features we like, including:


  • Electronic control panel with LED display;
  • Three cooling/fan speeds with a turbo mode for fast cooling;
  • A sleep mode for particularly quiet operation;
  • Auto restart (restarts unit in the case of a power outage);
  • 24-hour on/off programmable timer;
  • Heavy duty rolling castors for portability.

Price and Value
