Best 14000 BTU Air Conditioner

Best 14000 BTU Air Conditioner Guide

Having an additional cooling or heating source that supplements the central HVAC system helps maintain an even temperature throughout a household and lower its power consumption. The best 14,000 BTU air conditioners offer an easy way to regulate the temperature in a specific part of your home at affordable prices.

Even though their coverage range is limited, 14,000 ACs are still a reliable cooling source for mid-sized rooms. With so many models to choose from, selecting a 14,000 BTU AC that is a good fit for the space you want to cool is a daunting task.

In this article, I’ll supply you with the information that will make this process easier and recommend some of the best 14000 BTU Air Conditioner models produced by industry-leading brands.

Bottom Line Up Front

AC’s cooling output is one of the countless factors I consider while evaluating the unit’s performance capabilities.

Even though determining if an AC is suitable for a particular space without knowing its coverage range in impossible, this aspect doesn’t reveal much about the model’s efficiency or the options is offers.

Hence, I recommend choosing a portable 14,000 BTU model like the Whynter ARC-14S in case you need an AC stacked with advanced features.

On the other hand, GE AHEK14AC is one of the best available options for homeowners searching for a window-mounted unit with supreme cooling and dehumidification capacities.

Types of 14,000 BTU Air Conditioners

Every time I start looking for a new AC, I ask myself the same question. Which AC type do I want? The answer to this simple question helps me navigate the selection process faster by eliminating all AC types that don’t meet my requirements.

Depending on their installation method, air conditioners fall into three categories. Let’s take a look at the most common AC types.

  • Portable – Unlike other AC types, portable air conditioners are equipped with casters and handles that enable the user to change their position quickly. However, all portable models dispose of the warm air through an exhaust vent connected to a window, so users can’t move the unit freely.
  • Wall-mounted These ACs are compatible with sliding or double-hung windows and come with installation kits designed to support their weight. Their cooling outputs span from 5,000 to 24,000 BTUs.
  • Through-the-wall – Complicated installation process is the most common reason homeowners choose other AC types over through-the-wall models. However, these units have excellent performance capabilities.

The Coverage Range of 14,000 BTU ACs

The maximum size of an area a 14,000 BTU can cool varies from 500sq/ft to 800. However, the unit’s coverage range also depends on its type, so wall-mounted and through-the-wall models often cover slightly more space than portable ACs.

Moreover, the following factors can affect the air conditioner’s cooling range:

  • Unit’s position in a room
  • Ceiling height
  • Climate and outdoor temperatures
  • Insulation quality
  • Number of doors and windows in a room

Top tip: Use a free online BTU calculator to determine if a 14,000 BTU air conditioner is the right choice for the space you want to cool. 

Moreover, 14,000 BTU units aren’t a good fit for spaces under 500sq/ft as they’ll have to work harder to maintain the room temperature at the same level. Hence, a combination of contextual factors and the model’s cooling output can help you choose the right AC size for the space you want to cool.

Power Consumption and Energy Efficiency

Portable, through-the-wall, and window ACs use considerably less power than mini-splits or heat pumps. Most 14,000 BTU units need around 1,250 Watts to supply cooling for an hour at their maximum capacity.

So, you’ll have to spend between 5kW and 7.5kW of electricity to run a 14,000 BTU air conditioner for four to six hours. Hence, these units draw less power than most home appliances. What’s more, most models have Energy Saving and ECO modes that lower their power consumption.

My advice is to check the unit’s Energy Efficiency Ratio (EER) and opt for a model with an EER rating over 8.5. Also, getting an Energy Star-certified 14,000 BTU AC model will ensure you won’t have to spend a lot of power to control the room temperature in a specific part of your home.

It’s worth noting that outdoor temperatures also affect the AC’s power draw because they have to work longer to achieve and maintain a set temperature level during sweltering days.

Key Features of 14,000 BTU ACs

Most 14,000 BTU AC models offer an identical set of features. In addition, models with mechanical controls are rare, as most brands offer units with LCDs and digital control panels that grant the user access to all unit’s functionalities.

Here are some of the most common features of 14,000 BTU air conditioners:

  • Cooling, Dehumidification, and Fan-Only modes
  • Variable fan cooling and fan speeds
  • Sleep, ECO, and Energy Saver modes
  • Clean Filter reminder

Top tip: Besides reading the unit’s spec sheet, you should also try to learn more about the quality of its components to determine its long-term performance capabilities. 

The majority of high-end models are WiFi-enabled and compatible with Amazon Alexa or Google Assistant. The noise level of 14,000 BTU air conditioners varies from 40dB to 65dB depending on the type and the model, so units with low noise levels are an ideal fit for bedrooms or kids’ rooms.

Upkeep Requirements and Cost

Cleaning the air filter after approximately 250 hours of continuous operation and draining the condensate are the only maintenance requirements of 14,000 BTU air conditioners.

Moreover, opting for a self-evaporative model or a unit with a continuous drain function will eliminate the need to drain the water the unit accumulates while operating in Dry or Cool modes. Inspecting the unit after long periods of inactivity is advisable to ensure all its components are working properly.

Even though most brands offer one and two-year warranties for their 14,000 BTU AC models, their lifespan is significantly longer. On average, a portable AC lasts five to ten years, while a window or through-the-wall model usually lasts ten to fifteen years.

Prices of these units range from $400 to $600 for models with advanced features, while entry-level options usually cost between $200 and $300.

Selection Criteria

My main goal during the selection process wasn’t just to identify the best 14,000 BTU AC models but to find the units suitable for use in different residential contexts.

As a result, I couldn’t rely solely on my experience with 14,000 BTU air conditioners, and I had to utilize a variety of parameters to pick the models included in this article. Let’s take a look at the vital criteria I used while choosing the best 14,000 BTU ACs.

  • Brand reliability – I only considered the models manufactured by reliable brands that vouch for the quality of their products.
  • AC’s energy efficiency – This criterion has enabled me to eliminate 14,000 BTU air conditioners that need a lot of power to keep a 500sq/ft to 750sq/ft space cool.
