Best Window Heat Pumps: A Complete Buyer’s Guide

Window heat pumps are one of the essential items every homeowner needs. As the winter months approach, staying warm is a must, and window heat pumps are a cheaper alternative than other traditional ways to heat your home.

Window heat pumps give you the flexibility to bring the heat where it’s needed, instead of heating your entire home unnecessarily and throwing away your hard earned cash. Installation is quick and painless and accomplished easily with no more than two people.

With such an important purchase to be made (your warmth is at stake!), it’s vital to understand the different types of window heat pumps available to you before making your purchase decision. Options vary by type, power, size, brand, and, of course, price.

Outlined below is an in-depth review of the top 5 window heat pumps to aid you in your purchase decision before those frigid months hit.
Different Types of Window Heat Pumps

Like any product, there’s more than just one kind of window heat pump to consider. The most common are installed in your window and sealed to keep out the cold air. However, there’s also an option for a wall-mounted unit, though traditionally less common, and slightly pricier. We’ve listed the two main types of window heat pumps – window-mounted and wall-mounted – to help you better understand the pros and cons of each.


The more traditional of the two options, window-mounted heat pumps fit in most windows and typically heat a 400 square foot area. More powerful models can heat upwards of 600 square feet. Most models come with a 24-hour timer, multi-speed electronic controls, the ability to dehumidify a room at up to 2 pints per hour, and a remote control for hassle-free temperature regulation.

Window-mounted heat pumps also come in various BTU (British Thermal Units) outputs. Low-end units produce 4,000 BTU, while bigger, more powerful units can produce up to 11,000 BTU. The larger the room you desire to heat, the more powerful heat pump you’ll need. All window-mounted products include window installation kit and the necessary cords to fully set-up your unit.

Window-mounted units can be especially convenient due to their easy installation to make moving from room to room easier, in the event you have a limited amount of units. While occasionally moving your heat pump may not be ideal, it does make heating various rooms in your home cheaper than other standard heating options during those cold winter months.


The less traditional, wall-mounted heat pumps have most of the same functionality as their window-mounted counterparts but differ in a few key aspects that must be considered before reaching a purchase decision.

While the power of models can still vary significantly, wall-mounted units can be placed in more convenient locations, such as above your windows, to avoid unnecessary air leaking through your window, resulting in a quicker, more efficient heating process. This functionality is convenient during those winter days that are mild when a gentle breeze is welcome. Window-mounted units are incapable of allowing open windows, as the heat pump would only fall out and break.

One negative about wall-mounted heat pumps is the inconvenience of moving them. Usually, these units require a hole put in your wall, making it rather permanent. These types of units are usually more expensive, and often need a professional service to correctly install, adding to its initial cost.

Best Heat Pump Brands

Many brands specialize in the heat pump category, but there are a few that stand above the rest in regards to performance and accompanying reviews. Top brands include Frigidaire, Energy Star, Thermocore, LG, and Celiera.

Frigidaire specializes in the mid-quality heat pump category, at very fair price points. Their products get top reviews, and you get good bang for your buck.

Energy Star focuses on higher-end models, which come with a higher price tag, but are more user-friendly and aesthetically pleasing if that’s your cup of tea.

Thermocore, while less known than Frigidaire, has mid to high-end heat pumps for a slightly steeper price than its competitors, making it a reliable option.

LG, the well-known electronics brand, leaves its mark on the heat pump market as it does in numerous others. LG competes in the same price point as Frigidaire and Thermocore, making it a solid alternative to either option.

Finally, Celiera, specializes in the wall-mounted version of the heat pump category, making it a contender if this type of heat pump is desirable for your home. Understandably pricier, this is a more permanent heating option for your home, and more pleasing to the eye, as it doesn’t forfeit your window space.

Since a window heat pump is a pricey, substantial investment, we’ve created a list of the top 5 best window heat pumps. We based our rankings on a few factors we deemed most relevant to the consumer purchase decision: power, price, size, type, and ease of use.

1. Frigidaire 8,000 BTU 115-volt Compact Slide-Out Chasis Air Conditioner/Heat Pump with Remote Control


Frigidaire 8,000 BTU 115-volt Compact Slide-Out Chasis Air Conditioner/Heat Pump with Remote Control

This heat pump product is our top recommendation, and for good reason. At $440, it’s the lowest price point on the list, with the highest customer satisfaction reviews. This unit has the ability to be either a wall-mounted unit or a window-mounted unit, giving you extra flexibility.

This heat pump’s traditional look is exactly what you’d expect. Its multi-speed electronic controls with 24-hour on/off timer and remote control make it perfect for controlling your everyday heating needs. With a 7,000 BTU capacity and room to supplement, Frigidaire’s product has the ability to heat 350 square feet and dehumidify the space at 1.5 pints per hour. This unit’s dimensions are 23.3 x 22.6 x 15.4 inches.

If you’re looking for a standard, reliable heat pump, without the bells and whistles, this product is right up your alley and deserves serious consideration for your heating needs!

2. Energy Star 10,000 BTU 115-volt Room Air Conditioner with Reverse Cycle Heat Pump

Energy Star 10,000 BTU 115-volt Room Air Conditioner with Reverse Cycle Heat Pump

Coming in at an impressive 10,000 BTU, the Energy Star heat pump is another great option to heat your home during the cold winter months. With a price tag just north of $1,100, you pay for the added luxury of the Energy Star heat pump. This model is also available as either a window or wall unit.

This heat pump has a more appealing, modern look, and is available in multiple colors: Deep Red, Cobalt Blue, Designer White, Classic Beige, Black Onyx, and Pink Diamond. This model also has intrusion protection, a bonus for preventing the shenanigans often accompanied by small children, and effectively heats up to a 300 square foot space. You may also group this unit with others, if you happen to buy multiple, and program a central-air-like feel in your home.

Additionally, this heat pump is optionally Wi-Fi controlled from a smart phone, computer, or other mobile device, making its 7-day programmable schedule (with up to 4 setting changes per day!) a breeze.

3. Thermocore 12,000 BTU Window Air Conditioner, Heat Pump and Heater with Remote Control

Thermocore 12,000 BTU Window Air Conditioner, Heat Pump and Heater with Remote Control

With an impressive 11,000 BTU heating capacity, the Thermocore gives Frigidaire’s model a run for its money. While the Thermocore costs $540, it has more power than Frigidaire’s model, and the ability to heat almost double the space for only $100 extra. Unfortunately, this model is less versatile, and only available as a window unit.

The Thermocore also boasts 4 fan speed options, 4-way directional louvers, 24-hour timer, and auto-restart functionality in the event of a power outage, along with a remote control. Its mesh air filters are also washable, which reduces your maintenance cost.

Perhaps the most appealing feature of this product is its 1-year warranty on parts and labor. If your unit breaks within the first year, not only do you avoid having to buy parts, but the labor to fix your Thermocore is included as well. A definite bonus when you’re fighting those blizzard-like conditions!

4. LG Electronics 7,500 BTU 115-volt Slide In-Out Chassis Air Conditioner with 3,850 BTU Supplemental Heat Function

LG Electronics 7,500 BTU 115-volt Slide In-Out Chassis Air Conditioner with 3,850 BTU Supplemental Heat Function

With 3,850 BTU heat function capacity, LG’s product ranks lower on our list because of its lack of power, relative to its competition. Like the Frigidaire and Energy Star models, this unit has window-mounted or wall-mounted capability. With the LG costing around $500, it falls between the Frigidaire and Thermocore options listed earlier in our guide. Unfortunately, the heating component of this model is only usable when outside temperatures are above 45 degrees.
The LG can heat a room of 320 square feet with its multi-speed electronic controls, and can dehumidify at a rate of over 2 pints per hour. Additionally, this unit has “energy saver” mode, a 24-hour on/off timer, 4-way air deflection, and a “clean filter” alert when it’s time to wash/replace your filter. This unit also received some of the highest customer review ratings on our list.

5. Celiera 12,000 BTU Ductless Mini Split Air ConditionerCeliera 12,000 BTU Ductless Mini Split Air Conditioner + Heat Pump – Indoor and Outdoor Units

The Celiera weighs in as an impressive 12,000 BTU heating pump (the highest on our list), but it comes at a price. This product costs well over $1,000 from most authorized sellers, but has many features to help justify its higher price. Unlike the other models on this list, the Celiera is a solely wall-mounted unit.
This heat pump is a complete system, including an indoor (evaporator) unit, an outdoor (condenser) unit, complete installation kit, and wireless remote. This unit also has the ability to heat a large area of 540 square feet, more than capable of heating even your home’s largest rooms. There’s a quick install system included with this product that will reduce the time it takes to set up your product.
While slightly pricey, this unit also has a huge built-in perk: it frees up your window space for those uncannily nice winter days where you’d rather have a nice breeze flowing through your home. The Celiera enables this while opting for a window-mounted unit does not.

Features Any Heat Pump Must Have
While most of us probably have experience installing window-mounted heat pumps, wall-mounted units may come with more questions. Watch the video below to get a better understanding of how to install your wall-mounted heat pump!

There are many factors to consider before purchasing a heat pump to put your trust in to keep you and your family warm through the winter months. Below is a list we’ve compiled of the most essential factors to look for when shopping for your next heat pump unit.
Type – between wall-mounted and window-mounted units, it’s imperative you decide which model best fits your needs before purchasing a unit. If you think you’ll want to move the unit often, opt for the window-mounted variety, but if you’d like to keep your product stationary, a wall-mounted unit may be a better option.
Power – what size is the room you’d like to heat? Is it only 300 square feet? If so, you can get away with a lower BTU model, but if it’s a larger room (over 500 square feet), you’d be better off with a unit that provides a higher BTU output.
Price – heat pumps aren’t cheap, regardless of which model you’re looking for. If money isn’t a problem, you can find great models with nice perks for around $1,000. However, if your budget is half that, there are still solid models to choose from that will suite your heating needs.
Size – some windows are simply smaller than others, which may be a limiting factor in your purchase. While most heat pumps are similar dimensions, be mindful of your window dimensions while browsing for heat pumps. It would be a shame if the unit you purchased simply doesn’t fit!
Brand – some individuals have a particular affinity for certain brands. Maybe one brand offers a warranty while another doesn’t. Maybe you like LG products more than Frigidaire products. Ultimately, this comes down to preference, but could noticeably alter your purchase decision!

Final Thoughts

As you can see, there is a lot to consider before making a final purchase decision for a heat pump. It’s in your best interest to do sufficient research among products in order to make the best, most informed decision for your home needs.
Because heat pumps can be an expensive purchase, you want to make sure you buy the right one to avoid having to repeat your purchase in the near future. Hopefully, this guide has given you some insight into some of your top options, to help you make the most informed decision for you and your family!
