Window air conditioners are one of the best ways to cool off a room quickly, but you don’t have to put them into storage when winter rolls around. The best window heat pumps can heat and cool rooms up to 1,000 square feet and are an excellent alternative to portable systems when you need a system with more power.

Choosing a way to provide supplemental heating for a room in your home can be challenging. From portable air conditioners with heat to mini-split systems, there are plenty of options to choose from. That includes window air conditioners with a heating feature, which are often the best alternative for year-round usage in rooms from 300 to over 1,000 square feet.
#1 Frigidaire Median Air Conditioner with Heat
The Best Window Air Conditioner with Heat
While window heat pumps aren’t as popular as AC units that just blow cold air, Frigidaire has more dual models available than other companies. Our favorite is the Frigidaire Median FFRH1822R2, a high capacity unit that’s built for larger areas.
Compared to the other systems on our list, this window air conditioner with heat doesn’t feel outdated when it comes to the design. A small display is in the middle of this unit with an LED readout and flush-mount electronic controls. While it still has a large intake grate, it has dual vents at the top, which gives you 8-way venting for total control of the airflow.
On that note, the Frigidaire FFRH1822R2 has plenty of power, with a rating of 446 CFM on high. It’s rated for areas up to 1,170 square feet, and the heating capacity doesn’t lag far behind the cooling on this model. It has 16,500 BTUs of heat and 18,500 BTUs of cooling power, which makes it suitable for year-round use. You will need a 230/240-volt plug for this model, however.
Standard features on this AC and heat unit include a 24-hour on/off timer, three speeds for cooling, heating and fan mode, and an auto cooling mode. When activated, the system will automatically adjust the speed to coincide with the temperature in the room. Energy-saving and sleep mode are options as well, along with a washable mesh filter.
With a modern style and enough power to handle large rooms with ease, there are a lot of reasons to like the Frigidaire FFRH1822R2. That includes the 8-way venting and auto-restart, two features we’d like to see on more models from other companies. There’s really no downside to this particular model, and there is a larger 25,000 BTU variant available as well.
#2 Koldfront WAC25001W Heat/Cool Window AC
The Best Window Heat Pump with Dehumidification
Koldfront may not have the brand recognition of companies like GE or Frigidaire, but they are popular amongst builders and consumers interested in efficient units at affordable prices. The Koldfront WAC25001W certainly fits that bill, and it’s an excellent option if you want to keep moisture out of the room you’re trying to cool or heat.
Measuring 26.5”W x 26.5”D x 18.6”H, this window AC unit is large and heavy with a weight of 136 pounds. While that may not be ideal for some homes or windows, the Koldfront WAC25001W can cool or heat areas up to 1,500 square feet. With a rating of 25,000 BTU, it has more than enough power to keep you comfortable but is tied with the Frigidaire when it comes to heat.
Due to the size of this heating and cooling window AC unit, it needs access to a 240-volt power outlet. It’s relatively quiet for its size with a decibel rating between 58 to 63dBA and has four modes with heat, cool, auto, and dry. The first three are standard, while dry mode allows this system to double as a dehumidifier.
Like all of the best window heat pumps, the WAC25001W comes with a remote control and an electronic thermostat. It has a 24-hour timer, three speeds, and a couple of handy modes as well. Sleep mode adjusts the temperature over a 6 hour period as you sleep, while Energy-saving mode cycles the fan on in 10-minute intervals.
If the size isn’t an issue, it’s hard to go wrong with this AC and heat combo considering the price and its capacity. You’ll definitely need to consider a sturdy support for this system beforehand, but the weight is really the only drawback in our opinion. The Koldfront WAC25001W comes with a 2-year warranty with in-home service from the company.
#3 LG Window-Mounted AC with Heat Function
The Best Window AC unit with Heat for Medium Rooms
LG is more known for their high-tech appliances and smartphones than air quality equipment, but they make some of the quietest dehumidifiers around. If you’re looking for a small but powerful window heat pump for your home, the LG LW1216HR should be high on your list.
This is another AC unit with a simple design featuring top to bottom venting across the front and a directional louver on one side. A discreet control panel sits below the long louvered panel and lets you adjust the speed, temperature, or set a mode. This system has a 4-way directional airflow louver and can be controlled through a remote or via the onboard control panel.
LG may not win any design awards for this system, but it does have a 24-hour timer you can set and forget. The usual handful of modes are present as well, along with an auto-restart feature that will come in handy in the event of a power failure. A light will remind you when it’s time to clean and replace the filter, but there are only two speeds on this system, whereas others have three.
With a coverage rating of roughly 550 square feet, this heating and cooling system is best suited for small to medium rooms. It has a 12,000 BTU cooling rating and is listed at 11,200 BTU for heat, so it’s equally effective whether you need to cool down a room or warm it up. This system is small for its size at 14.97”H x 22”W x 23.6”D and tips the scales at 93 pounds.
This is another entry-level window air conditioner with heat that won’t break the bank but is one of the better options when you want a system that can heat as well as it can cool. The only common complaint we found from users was the noise level, although some of those issues come to quality control issues. This AC unit is backed by a standard 1-year warranty from LG.
#4 Friedrich Kühl Series Air Conditioner with Heat
The Best Window Air Conditioner with Heat for Connected Homes
Most window air conditioners share one thing in common – their design. While Friedrich has several systems that have a traditional sense of style, this Kühl series air conditioner bucks that trend and is one of the smarter units on the market.
The Friedrich KEQ08A11A is a sleek machine that will look great hanging from any window in your home. Modern is the first word to come to mind with this system, which has dual louvers next to a small digital control panel. It’s well-built with steel inner walls, a solid steel blower wheel, and a fully encased fan motor.
This sleek machine is also designed with noise levels in mind. While we couldn’t find a decibel rating, the company used dense sound-blocking insulation in this air conditioner and thick rubber motor mounts. Dual filters are another unique feature as the KEQ08A11A has both carbon and antimicrobial filters. It’s rated for rooms around 300 square feet in size with 8,000 BTUs of cooling power and 4,000 BTUs of heat.
Another advantage of this heat and air window unit is its connected nature. This version has Wi-Fi connectivity, which allows you to control the system from anywhere through the Friedrich Connect app. You can control multiple systems from the app, set 7-day schedules, or adjust the temperature, modes, and timer.
Friedrich put a lot of thought into the design of this system, and while it’s expensive, it’s the best option for small to medium rooms in connected homes. While it’s not the most powerful unit, it’s packed full of useful features and comes with an excellent 5-year guarantee from Friedrich.
#5 GE Heat/Cool Window Air Conditioner
An Affordable Window Air Conditioner with Heat from GE
General Electric has been a mainstay in American households for decades, and while their catalog has narrowed in recent years, they have an excellent line of HVAC products. That includes window-based AC units like the GE AEE08AT, which is perfect for smaller rooms that need supplemental heating and cooling.
The GE Heat/Cool window air conditioner has a classic design with a large grill in the front and a long 4-way adjustable louver across the top that blows hot or cold air. A small electronic control panel allows you to adjust the settings, but you can also take control of this system with the included remote. This air conditioner uses the companies EZ Mount system, which allows for window or in-wall installations.
As for the features, this unit comes with a 24-hour timer you can use to turn the system on or off. There is a reminder for the washable filter and three modes with cooling, heating, or fan-only. Each mode has three speeds with a maximum airflow rating of 270 CFM. It’s not Energy-Star certified, but it does have an energy saver feature.
Measuring only 22.6”W x 24.6”D x 15.8”H, this unit is small enough to work with a variety of windows and is one of the lighter models with a heat pump at 80 pounds. The heat rating for this system is 3,800 BTU, while the cooling capacity is listed at 8,000 BTU. It’s not as powerful as other 2-in-1 window units from that standpoint but only requires a 115-volt plug for power.
This window air conditioner may not be the sleekest model on our list, but it’s efficient and affordable. At a little over 15” tall, it won’t take up much space in a window and has all the features you could as for from a unit this size. That said, the GE AEE08AT is geared more towards cooling than heating, given the heating power.
#6 Amana Window Heat Pump Air Conditioner
A High-Powered Heat Pump from Amana
Amana is another brand that’s produced their fair share of AC units over the years. They also have one of the larger selections of AC and heat systems on the market today. Our top pick from the company is the Amana AH183G35AX, a powerful unit with a heat pump.
This heating and air conditioner is capable of producing 17,300 BTU of cooling power or 14,300 BTU of warmth. It has a heat pump with a reverse cycle but also has an electric backup rated at 11,000 BTU. The system has three speeds with Low, Medium, and High in both modes, and an impressive airflow rating of 590 CFM on high.
Simplicity is part of the charm of this system with a smooth curved front and streamlined design. Four-way louvers are on the right side of the unit, while an electronic control panel sits discreetly behind a small swinging door. You can set the speed and temperature from the front of this unit or by using the included remote control.
With a weight of 143 pounds, you’ll need some assistance and additional bracing to lock this unit into place unless you opt for a thru-wall installation. The Amana AH183G35AX is geared towards double-hung windows and measures 26”W x 32.5”D x 16.8”H. It’s a deep unit due to the small heat pump and backup, but of average height and width for its capacity.
This AC unit with heat is more expensive than models with comparable ratings but is highly effective in colder climates and has an electrical backup heater as well. It’s one of the more powerful systems in terms of airflow, and we like the tiered warranty. On the downside, we did notice some complaints related to noise levels, although that’s expected to a degree because of its size.
How to Find the Best Window Heat Pump
While there are plenty of appliances in the HVAC world that can produce both warm and cool air, the selection begins to narrow when you want a window AC unit with heat. These systems are only sold by a handful of manufacturers, and only larger units have heat pumps while most have an electric coil heater. Both can be highly effective in the right size room, which is the first area you need to consider.
Think about the room you are trying to heat…
Most window AC units are designed to work in standard single or double-hung windows, so you can install these systems in a variety of rooms in your home. If it has a large enough window, you can probably find an air conditioner to fit it, although models with heat tend to start out at 8,000 BTU and top out at around 25,000 BTU.
You will need to measure the window to make sure the unit will fit, but you should also consider how well it’s insulated. Is it a drafty area that loses a lot of heat during the winter? Unless you plan on adding insulation and weather stripping, you may want to go with a more powerful system to compensate for the heat loss.
The other area many consumers overlook are power outlets. Window AC units will require a 115-volt or 220-volt outlet. Both are found in homes, apartments, and condos across America, but 220v outlets are typically reserved for rooms like kitchens and laundry rooms. 115v outlets can be found in any room of your home, but units that use these plugs aren’t as powerful as 220/240v models.
Window vs. Portable Air Conditioner
While a central HVAC system is the best way to cool an entire home, they are expensive and overkill for smaller residences. They are also a permanent solution, whereas window-based air conditioners and portable systems can be stored out of sight when they aren’t needed. Both models are also capable of producing heat, which leads many consumers to pit one system against the other.
The biggest advantage of a window air conditioner with heat compared to a portable model is power. While there are plenty of portable systems over 10,000 BTU, window-based units are more powerful across the board. They provide more cooling and heating power for a lower price but can be unsightly depending on the location.
Window air conditioners will take up more space when removed from a window and are harder to install. General maintenance, bugs, and even intruders can be a concern with this style as well, but they can be incredibly efficient compared to their portable counterparts.
With a portable air conditioner, you have the freedom to use the system in a variety of rooms, whether it has windows or not. They have more venting options and can have just as many features as a large window AC unit. While easier to store, they will take longer to cool down larger areas and aren’t as efficient overall.
Heat and Air Window Air Conditioner Sizing
If you’ve purchased or have looked into HVAC systems or portable AC units, you may be familiar with the term BTU. It stands for British Thermal Units and is the main measurement you need to be aware of when sizing a new window AC unit with heat for your home. Unlike traditional window air conditioners, there are two numbers to take into account with these systems.
Every window air conditioner with heat will have a BTU rating for both heating and cooling. In some cases, you’ll notice that number is significantly skewed towards cooling while other systems provide a more even experience. This is where you need to consider how often you will use the heat feature and the system as a whole.
For living areas that see a lot of usage, you’re better off choosing a system with even heating and cooling capabilities. They can be a bit more expensive but are suitable for use at any time of the year regardless of the weather outside.
While larger BTU ratings mean more heating and cooling power, square footage and other factors come into play as well. If you want to keep things simple, our BTU calculator can help you hone in on the right sized system.
EER, HSPF, and Energy Star Ratings
BTU may be the main specification manufacturer’s use when it comes to heating and cooling power, but it’s not the only important one that should be on your radar. Depending on the model and company producing the window AC unit, you may encounter the terms EER, HSPF, or see an Energy Star seal.
EER is short for Energy Efficiency Ratio and is used to measure how efficient a room air conditioner is. Systems with a high EER rating are more efficient and will save you money in the long run, but can cost significantly more. While not as common on Window-based air conditioners, HSPF refers to the Heating Seasonal Performance Factor and tells you how efficient the heating function or heat pump is.
There are also systems that are Energy Star rated for efficiency, which means they are rated to use at least 10% less energy than non-rated models. These air conditioners are priced at a premium, and there isn’t a wide selection when you’re looking for a solid window air conditioner with heat.
Window Air Conditioner Features
How many features you’ll find on a typical window air conditioner depends on how much you’re willing to spend. That said, both budget-friendly and premium models share a select set of features, and we’re going to touch on the most common ones found on low and high-end systems.
- Venting – Warm or cool air is returned to your home through directional vents on a window AC system. Most modern systems have 4-way venting, which allows you to direct the airflow left, right, down, or up. 8-way venting is also an option that uses two 4-way vents for more control over the airflow in a room.
- Speeds – Every window air conditioner will have multiple speeds, and in our research, we found that most have three. More speeds doesn’t necessarily mean one system will have a higher CFM rate than another, and they should carry across heating, cooling, and fan modes.
- Eco Mode – If an Energy Star certified AC system isn’t in your price range, you could still save some money from operating costs through units with an Eco mode feature. How they work varies from one manufacturer to the next, but all are designed to conserve energy while heating or cooling a room.
- Sleep Mode – This feature is only important if you intend to use a window air conditioner in a bedroom or anywhere that noise could be a problem. Sleep mode can adjust dim the operating lights and adjust the speed while people are sleeping in the room or nearby.
- Filtration – Every air conditioner on our list will have some form of filtration, which usually comes in the form of a washable filter. Some manufacturers take things a step further, however, with carbon-based filters or multi-stage systems.
- Auto Restart – This simple feature is missing from a surprising amount of models and is incredibly handy if you have problems with power outages. Auto-restart will automatically start your system if the power goes out, and something you’ll be thankful for on a cold winter day.
- Timers & Scheduling – Delayed start timers are popular with this class of AC unit as they allow you to automatically start or stop your unit at a certain time. Some systems let you schedule running times as well up to 7 days in advance.
- Wi-Fi – If you live in a connected home or simply want to control your system with your smartphone, you’ll want to consider a Wi-Fi window air conditioner with heat. It’s the most expensive feature found on this type of system, but worth it if you appreciate the convenience.
In addition to the features above, most window air conditioners come with an electronic control panel and a remote. Some have dehumidification modes or offer advantages like intrusion protection or insect barriers as well.
Window AC Unit Warranties
Given the price of high-quality window air conditioners, you want to make sure your unit doesn’t stop working when the weather goes from mild to wild. Unfortunately, there are a variety of reasons why air conditioners stop working, from quality control issues to poor maintenance on the homeowner’s part. While a solid warranty can’t help you take care of your system, it can save you from some major headaches down the road.
In our research, we found that most manufacturers offer a warranty between 1 to 3 years on window air conditioners with heat. In many cases, it comes down to the brand as companies like Frigidaire and Friedrich tend to have longer guarantees than other brands. As always, consider an extended guarantee if you’re concerned about the warranty. We also recommend ensuring your unit is purchased from a reputable dealer to avoid quality control or shipping issues.
Window heat pumps may not be as popular as other supplemental heating solutions, but the best models are highly effective during the summer and winter. Just remember to keep your budget in mind along with your needs. If you feel a portable air conditioner heater combo or a powerful mini-split for DIY is better suited to your needs, we have you covered.
