8 Best 15000 BTU AC Units – Comfortable Temperature during Sweltering Summer Heat!

View Article Statistics

If all you know about air conditioning units is that they keep your home at 68℉, you know next to nothing about them. The best 15000 BTU air conditioner will shelter you from the sweltering summer heat. But, be careful – the wrong one will make your energy bills go through the roof and leave areas of your home uncomfortably hot and humid.

On our quest for the best 15000 BTU air conditioner, we considered four key characteristics. The type of unit was most valuable, as some consumers prefer window units while others enjoy portable air conditioners. BTUs and coverage areas go hand in hand, so we focused on 15000 BTUs and 300-800 square feet of indoor coverage. Dimensions were critical because some consumers have more space to work with, and the warranty was vital for saving money in the long-term. Now, let’s take a closer look at our top 15000 BTU air conditioners.

This system is so powerful that you no longer have to be a stickler for keeping the RV door shut.

The environment and electronics don’t usually go hand-in-hand, but you can expect that with this AC unit. This Perfect Aire window unit boasts an energy saver mode that’ll keep your monthly energy bill at the forefront — it’ll turn itself off automatically when your desired temperature is reached to save energy and cash.

This unit from Perfect Aire comes with a nifty remote control with a “Follow Me” function that’ll essentially turn your remote into a thermostat.

The TCL 15W3E1-A 15,000 BTU Window Air Conditioner is what your new home needs if you crave the chill while keeping money in your wallet.

This AC unit covers 700 sq. ft. of living space for a fraction of the cost of other popular units — and, it sure covers every nook and cranny. This TCL air conditioner has multi-direction louvers that blow in eight different ways. Now, you don’t have to sit right in front of the AC to cool off on a hot day, just sit back and relax as this air conditioner keeps you comfortably cool.

The energy efficiency this unit provides will be enough to seal the deal for any Earth lover. With an EER of 11.9, this unit is about 50% more energy-efficient than the average air conditioner. The Eco Mode setting makes this possible — this AC unit will automatically turn off the compressor once your room is cooled to your ideal temperature.

Whirlpool 14,000 BTU Dual-Exhaust Portable Air ConditionerBest Air Conditioner & Dehumidifier Combo

Features
  • Type: portable
  • BTUs: 14,000
  • Coverage area: 400 sq. ft.
  • Dimensions: 15.6 x 17.9 x 39.3 in.
  • Warranty: 1-year limited

 More features: remote control, dehumidifies up to 3.8 pints per hour, dual-exhaust, 3 speeds, 24-hour timer, comes with window kit

The Whirlpool 14,000 BTU Dual-Exhaust Portable Air Conditioner is the perfect solution if your rooms tend to get scorching hot and unbelievably steamy.

This portable AC unit (15000 BTU) is a dehumidifying phenomenon that can wick up to 3.8 pints of water from the air every hour. Lowering the humidity can make the air less heavy to breathe, drop the “Feels Like” temperature by several degrees, and keep gross grime and mildew from growing on the surfaces. Your air will always be dry, crisp, and clean!

The dual hose exhaust system turns this “good” AC unit into a “great” one. Single hose systems are problematic, to say the least — they create negative pressure that allows hot air to leak back into your room from the cracks in your windows and doors. The two hoses on this unit will keep warm air out for good and draw cold air to keep your system chilled. This AC unit will never have to work against itself as it tries to keep your room comfy. But, it can still be quite loud.

Pros
  • Dual-exhaust
  • Can pull nearly 4 pints of water out of the air every hour
  • Rolls nicely on carpet
Cons
  • Can be a little loud
  • The remote is sometimes non-responsive

An all-in-one HVAC unit doesn’t exist unless you’re purchasing this wildly overlooked TCL 14PH31 14,000 BTU Portable Air Conditioner.

Many AC units do a wonderful job keeping bedrooms cool, but they’ll collect dust in your closet when winter finally arrives. This TCL AC unit also doubles as a heater, making a cool and cozy temperature a year-round guarantee. For an extra $100, you can count on this powerhouse to beat the heat, cold, and moisture. Unfortunately, the remote can be a bit tricky to use.

This nifty AC unit will give you 350 sq. ft. of coverage and reach every square inch with coolness thanks to the automatic-swivel blowers. When the high temperatures come with insane humidity, this unit has your back. It’ll suck any excess moisture out of the air to keep indoor air cool and easy to breathe. The system will then automatically evaporate the moisture to keep you from getting down and dirty draining the device. Just set it and forget it!

Pros
  • Doubles as a heating system
  • Can chop indoor temperatures by 15℉ in as little as 30 minutes
  • Automatically evaporates all humidity

Buying Guide

Deciding to buy a brand new 15000 BTU AC unit is the first step toward a relaxing and comfortable home during the steamy summer months. But, not every AC unit on our list will make a great fit in your home. So in this buying guide, we’ll be discussing how to figure out which of our favorite units best meets your needs. To do that, we’re going to be reviewing the minor details that make each 15000 BTU unit unique. We’ll then conclude the buying guide section with the answers to some frequently asked questions.

Advantages of 15000 BTU air conditioners

It’s safe to say that a 15000 BTU air conditioner boasts quite a few unique benefits. Below, we’ll discuss some of the key features and advantages that stand out most.

  • Portability: You probably won’t be using your AC in the winter the same way you use it in the summer. 15000 BTU units are small and portable enough to be detached from the window and stored in a hall closet until those hot summer months eventually return.
  • Medium-sized coverage: A 15000 BTU unit can cool a small-sized apartment on its own, so you won’t need to purchase an individual unit for every bedroom.
  • More energy-efficient: Central AC units rack up heft energy bills and run practically 24/7. Portable 15000 BTU air conditioners, like the TCL 15W3E1-A 15,000 BTU Window Air Conditioner, are Energy Star rated, which can keep your monthly energy bills low.
  • Convenience: Many 15000 BTU units come with remote control functionality, meaning you can adjust the temperature and turn it on and off from across the room.

It’s important to understand that a 15000 BTU AC unit won’t make sense in all homes, especially in scorching areas of the country or in large spaces.

Things to consider before getting a 15000 BTU AC unit

8 Best 15000 BTU AC Units – Comfortable Temperature during Sweltering Summer Heat!

Before you buy a brand new 15000 BTU air conditioning unit, you’ll want to think about the following things:

  • How much window or floor space you have;
  • Whether the room you plan to put it in has a window;
  • How large the desired room or area is (in square feet);
  • How much you value energy efficiency and low energy bills;
  • What you’re willing to spend on an AC unit;
  • Whether you need a high-tech unit (Wi-Fi, remote control, LED, etc.).

Now that you have a general idea of what you’re looking for, we’re going to walk you through decision-making and buying processes.

Type

There are three major types of 15000 BTU AC units: portable, window-mounted, and rooftop.

Portable AC units like the Whirlpool 14,000 BTU Dual-Exhaust Portable Air Conditioner will rest on the floor next to a window. An air hose will be wedged within the window to allow hot exhaust and air to escape. These units also have wheels so you can roll them from room to room.

Window-mounted units like the TCL 15W3E1-A 15,000 BTU Window Air Conditioner are lodged directly below an open window and are a bit too bulky to move. The noisier pieces of the unit are housed outside the window, meaning these AC units tend to be on the quieter side.

Rooftop units like the Dometic 15000 BTU RV AC are primarily installed on large vehicles like RVs and campers. This style of AC unit can improve cooling and airflow in your camper as you’re road tripping across the country.

Power and efficiency

The power of an AC unit is described in BTUs, which stands for “British thermal unit.” In our reviews, we focused mostly on AC units within the 13000 to 15000 BTU range. A unit of this power will consume about 1250 to 1875 watts per hour, on average.

To figure out if an air conditioner is energy-efficient, all it takes is a simple equation. Divide the BTU value by the approximate wattage to get the EER or the “energy efficiency ratio.” The higher the number, the more energy-efficient the unit is.

If you value energy efficiency and want to save a few bucks on your electric bill, you may wish to purchase an Energy Star certified air conditioner with a high EER rating (11+).

For example, the Friedrich CCW15B10A Air Conditioner costs just $125 to run each year.

Coverage area

The power of your air conditioning unit will determine how much indoor coverage it offers as well. The coverage area is often defined in square feet and describes what space your AC unit can keep cool.

An AC unit should be able to keep one square foot cool for every 20 BTU. However, this isn’t an exact science. That explains why AC units like the Black + Decker BPACT14WT Portable Air Conditioner offer just 350 square feet of coverage while the Perfect Aire 15,000 BTU Window Air Conditioner can cover an impressive 700 square feet (the size of a tiny apartment).

A 15000 BTU unit will have a coverage range of 350 to 700 square feet. Portable units tend to hover around the lower end of the spectrum, while window-mounted units offer maximum coverage.

Design and controls

8 Best 15000 BTU AC Units – Comfortable Temperature during Sweltering Summer Heat!

One of the most important things to consider when buying a new 15000 BTU AC unit is how it works. Nearly every basic AC unit comes with button controls on the unit to adjust settings, temperature, and fan speeds.

Most AC units these days will come with remote control for convenience purposes as well. Now you can control the temperature and fan speed of your air conditioner from across the room or while you’re lounging on the couch.

Modern AC units, like the Friedrich CCW15B10A Air Conditioner, also have Wi-Fi connectivity and voice command capabilities. These tech-savvy systems allow you to control your home’s ventilation via your smartphone or your voice.

Functions

AC units usually have one primary function: distributing cool air to maintain temperature control. However, some units offer more advanced features that can get you more bang for your buck and greater convenience overall.

For example, the Whirlpool 14,000 BTU Dual-Exhaust Portable Air Conditioner also doubles as a dehumidifier.

A dehumidifier feature can pull moisture out of the air and lower indoor humidity, helping your room feel even cooler. Less humidity can also make air easier to breathe and reduce the growth of mold and mildew in your home.

Most AC units will also come with a “fan-only” function that’ll simply distribute whatever air is currently in the room. This is a great feature to have if you enjoy a nice gentle breeze while you’re sleeping.

Dimensions and weight

Since a 15000 BTU air conditioning unit is considered “middle of the road” in terms of power, these units also tend to be on the smaller side.

Portable AC units come with wheels so that you can move them from one room to another, and they typically don’t take up more than 4 square feet of floor space.

Window-mounted units tend to be a bit bulkier, but it’s important to remember that half of the unit will extend out of the window. These units are typically under 30” wide, so you’ll need to check that your specific model will fit in the desired window.

Warranty

A 15000 BTU air conditioner will cost you an average of $500 or more for a good unit. So, you want to be sure that you’re getting your money’s worth by purchasing a unit with a warranty.

Most of the AC units among our favorites come with a one-year warranty on labor and parts. If your AC suddenly stops working within 365 days of your purchase, you might be able to get a free replacement or repairs done by the manufacturer.

Some of the units on our list have extended warranties on specific parts. For example, the Friedrich Chill Series CP15G10B Room Air Conditioner comes with a five-year warranty on the sealed refrigerant system. This system keeps the Freon from leaking out of the AC unit, so this warranty can save you a lot in replacement costs.

What else can be important?

8 Best 15000 BTU AC Units – Comfortable Temperature during Sweltering Summer Heat!

15000 BTU air conditioners are pretty straightforward, but there are a few extra features or characteristics you’ll want to weigh. These include:

  • Window mounting & exhaust kits: Both portable and window-mounted AC units need to be secured to a window to allow airflow in and out. Make sure you measure your window’s width before buying an AC unit to ensure that the window mounting or exhaust kit will fit snugly.
  • Washable filter: AC units with washable filters will save you some cash on filter replacements every few months. These filters are easy to clean with soap and water.
  • Quiet operation: A 15000 BTU air conditioner can be powerful, so it’s not surprising that these machines can be loud. Check the decibel output of your desired AC unit to check that it’s low, preferably beneath 50 decibels.
Most of these features are purely for convenience purposes. You might find quiet operation to be crucial while another person prefers washable filters more. Decide what’s important to you.

Prices

Most 15000 BTU air conditioners will be a little more costly than you’d expect. You should anticipate paying between $300 and $800 on a new unit, with window-mounted air conditioners being pricier than portable ones.

The Black + Decker BPACT14WT Portable Air Conditioner is the most affordable air conditioner on our list. Listed at a little more than $400, this unit will offer up to 350 square feet of coverage, pull moisture out of the air with the dehumidifying feature, and have a remote control.

Higher-end models include the Friedrich CCW15B10A Air Conditioner, boasting a normal list price of over $800. This tech-savvy window-mounted unit can be controlled via voice or Wi-Fi connectivity, is Energy Star certified, and can keep large rooms comfortably cool.

FAQ

Not cleaning your 15000 BTU air conditioner can pose a few problems, such as a loss in efficiency and the build-up of grime and mold. Fortunately, cleaning an air conditioner is a relatively simple task. The most important thing to remember is to turn off the AC unit before beginning to clean it. Then, slide the filter out of the AC unit. After, you can vacuum the dirt and dust build-up. Some filters require a more intense cleaning, so you might be able to soak it in hot soapy water after cleaning. Detach the unit’s front grille, spray it down with soap and water, and use a rag or bristled brush to scrape away any grime. Scrub the unit’s interior and then allow all pieces to dry completely before putting it back together.

The exact amount of energy consumed by a 15000 BTU air conditioner will depend on the make, model, and power output of the unit. Generally speaking, a 15000 BTU unit will consume about 1250 to 1875 watts per hour. Recent data shows that it costs about $0.13 per kilowatt-hour of usage, also referred to as “kWh.” So if you’re running the unit 24/7 during the summer months (about 90 days), you’ll spend between $350 and $525 on cooling costs. These numbers equate to about $0.16 to $0.24 an hour, or an average of $146 a month for continuous usage in summer, so the real number will be much lower.

It can be challenging to get a high-powered air conditioning unit without the excess noise that comes with it. Some AC units are known for being “quiet,” recording under 50 decibels when in use. For reference, 50 decibels is quieter than the sound of normal conversation. Other units will produce sounds of 70 decibels or higher — this is about the same level of noise that comes from a vacuum cleaner or a washing machine. It’s also important to remember that your AC unit won’t make this loud sound 24/7. In most cases, an air conditioner on its lowest setting will sound like a muffled conversation.

Our Verdict

Our favorite AC unit in our 15000 BTU air conditioner reviews is the Friedrich Chill Series CP15G10B. This model offers 700 sq. ft. of cooling, keeps temperatures 20+ degrees lower than outside, and hardly makes a sound!

In a close second is the Black + Decker BPACT14WT Portable Air Conditioner. It can cool a room in as little as 15 minutes, keeps the air cool and dry, and has a convenient 24-hour timer.

The third place goes to the Dometic Brisk II Rooftop Air Conditioner. This model is simple to install on an RV. Also, it boasts several vents to keep all rooms cool and is the “gold standard” for RV AC units.

We hope that this guide helped you find the best 15000 BTU air conditioner, and now, you can enjoy the cool breeze during those hot summer months!
