LG Electronics LP1414SHR Review

LG Electronics LP1414SHR ReviewIf you like the idea of being able to cool and heat a room efficiently with the same unit, then we suggest you take a good look at the LG Electronics LP1414SHR 14000 BTU Portable Air Conditioner with Heat Pump. However, what should you know about the LP1414SHR? And is it worth the hefty price tag?

For all of this and more information about this new portable air conditioner from LG, including our own candid thoughts and impressions, please keep on reading.

Key Features & Specfications

~Cooling Coverage Area and Power

The LP1414SHR is a 14000 BTU air conditioner capable of cooling rooms of up to a maximum of 600 square feet in size. As always, we encourage you to take this rating as only an approximation of the room size this unit can handle. For example, if the room to be cooled has vaulted ceilings or has one or more sunny windows, you can expect this coverage estimate to shrink considerably. Nevertheless, most users should find this model effective for larger rooms (or adjoining rooms) of around 500 square feet in area.

~Heater Function

Unlike many dual air conditioners/heaters, the LG LP1414SHR provides supplemental heat through a true heat pump, rather than a simple heating element (like those employed by infrared heaters, for example). Heat pumps are among the most efficient ways to heat a space, and essentially work by running the AC unit in reverse. To learn more about how heat pumps work and why they are so advantageous, check out this wiki entry here.

The heater, like the cooling function, is rated at 14000 BTUs. This makes the LP1414SHR an excellent choice for those seeking year round use for effective and efficient heating/cooling.

~Exhaust Hose Configuration

It is important to understand how a portable air conditioner vents, as it has some relevance to its overall efficiency. Just about all portable AC units come in one of two possible venting configurations: either single or dual-hose vents. Each has its advantages and disadvantages.

Dual hose vents are technically the most efficient kind (all other things being equal). This is because one of the vents is actually an intake – which pulls in outdoor air for the sole purpose of cooling off the compressor. This air is then ejected back outside, making it a dedicated compressor cooling loop. This allows the air within the room to be undisturbed, and the cooling loop to be completely segregated. The only real disadvantage of this type of system is its relatively higher cost compared to a single hose system.

A single hose exhaust is just that – one hose that exhausts air which has been passed over the compressor to cool it. The only hook is that this system by necessity must use indoor air to cool off the compressor. This has two consequences: 1) by removing some of the room air that is being cooled, the unit must work harder to replace it; and 2) because air is only being exhausted by the single hose, a weak negative air pressure (i.e., vacuum) is created in the room, which coaxes outdoor (warm air) to infiltrate around gaps and cracks and enter the room, which also creates more work for the unit. The big benefit of these systems is that they are considerably cheaper than dual hose systems.

In this case, the LP1414SHR uses a single hose exhaust. However, this does not mean that this air conditioner is “inefficient.” To judge efficiency overall, one must also take into consideration an air conditioner’s Energy Efficiency Ratio (“EER”) as we discuss in more detail next.

~Energy Efficiency Ratio (EER Rating)

The best way to compare the energy efficiency of air conditioners (portable or otherwise) is to: 1) understand how they vent (i.e., whether they are single or dual hose models); and 2) calculate their EER or “Energy Efficiency Ratio”.

An EER is just a fancy way to express the product of an air conditioner’s total BTUs divided by its wattage. Higher numbers are better; however, most air conditioners will fall between 8.5 and 10.0, with the average model running around 9.0.

Here, the LP1414SHR draws a maximum of 1380 watts, so if 14000 (BTUs) is divided by 1380, we get an EER of 10.1 – this is a very good score, and means that, despite losing a bit of efficiency with the single hose exhaust, the LP1414SHR is still a very cost effective model that delivers lots of cooling for every watt of energy it consumes.

~Condensate Removal System

The LP1414SHR uses a modern self-evaporating condensate removal system. Unlike the old days when you needed to either manually dump out a collection pan or install a drain hose, this model essentially dries the condensate quicker than it can accumulate by passing it through the exhaust air stream. This works great in most cases, and you probably will never need to drain any water from this unit. Take note, however, that this system can sometimes be overwhelmed in environments with extreme humidity, in which case some condensate may still accumulate and require periodic draining.

~Operating Noise Level

We can spend hours going over the challenges of quantifying noise levels, but at the end of the day, it is ultimately a subjective response. As far as decibels are concerned, the LG LP1414SHR is rated to produce only about 58 db of sound pressure from the front of the unit. That is actually quite good for a unit that has 14000 BTUs of cooling power, but if you are very sensitive to sound, this unit – and just about any unit – is likely to be a bit noisy for you. For the average consumer, however, the LP1414SHR should be relatively quiet or at least tolerable in terms of operating noise.

~Weight & Dimensions

Portable air conditioners – even under the best of circumstances – tend to be big, bulky things. Nevertheless, the LP1414SHR presents a comparatively tall and sleek outline. This model measures 18.50″ wide, 33.3 tall and just 13″ inches deep. As such, it occupies relatively little floorspace and can be situated easily among/around your furniture.

As far as its heft, you won’t want to lug this puppy up or down the stairs too often – at roughly 72 pounds it is quite a handful! However, this is a pretty typical weight for most portable air conditioners in this BTU class.

~Other Notable Features

  • Digital thermostatic control & display;
  • Full function remote control;
  • Automatic louver swing;
  • Energy saving mode;
  • Three fan speeds;
  • Auto restart (in the event of power interruption);
  • Bucket (water) full indicator;
  • Washable air filter;
  • Rolling casters for mobility.

Price and Value

In case you haven’t noticed, 14000 BTU portable air conditioners tend to be expensive, and those with true heat pumps carry an additional premium. That’s why we think that the LP1414SHR’s current price, which is hovering around $643 shipped (at the time of writing), is actually very good in our view. Add to that the contemporary LG styling and sophisticated digital controls, and you have a great deal on a combination air conditioner/space heater.

LP1414SHR User Reviews

As a relatively new model for 2014, this unit (at the time of this writing) has only a handful of reviews, but they are predominantly 4 and 5-star. Below are the actual reviews from for this product on amazon.com; see what people had to say for yourself:

Overall Pros/Cons

Concluding Thoughts & Opinions

You can certainly find a slightly less expensive 14000 BTU portable air conditioner that cools only. But if you want a model that both cools and heats – and looks very good while doing it, the LG Electronics LP1414SHR is a good choice. This unit provides a lot of value and performance for the price, and leverages a modern design and digital controls that most users will appreciate.

In addition, while it a single-hose system, the high EER of 10.1 means that you are spending your cooling dollars wisely. And if you use this unit to provide supplemental heat in winter, you are certain to reap additional savings thanks to the terrific efficiency of the heat pump. All-in-all, this is a great combination cooling/heating unit that can provide year-round comfort.
