Beginner’s Guide to the Best Window Air Conditioners With Heat

What Is a Window Air Conditioner With Heat?

A window air conditioner with heat is, much as you’d suspect, a window-installed air conditioner that doubles as a heater during cooler weather. There are two main design options when it comes to such units:

  • Air Conditioner/Heat Pump Combination: These units use the refrigerant cycling process of air conditioners to produce heat instead of cool air when they’re in heater mode.
  • Supplement Heat: These models rely on conventional compressor, evaporator coil, and condenser components for their air conditioning function with the addition of heat strips. These strips have a heating element that, with the built-in fan, fills a room with heated air instead of using the conventional AC’s refrigerant cycling function.

Air conditioner/heat pump varieties are more efficient than supplemental heat units but tend to be significantly more expensive. However, the higher price tag is more than made up for with their lower energy costs, somewhat the reverse of the best portable air conditioners.

Supplemental units generally come at a lower price but are less efficient, which will increase your power bill despite inferior performance. They’re often smaller, however, which means their main benefits are space-saving and lower initial costs.

Window Air Conditioners With Heat vs Other Models

The most obvious difference between window air conditioners with heat and other window air conditioners is that they combine an air conditioning function with some sort of heating capability. The design of the heating component also comes in two basic types. One uses the standard refrigerant-cycling method for both heating and cooling, and the other uses a separate heating element to blow hot air into a room.

The dual functionality and the differences in design also introduce other differences. These units are often less efficient for cooling compared to standard models with the same BTU output, EER rating, and Energy Star status. However, their overall efficiency as appliances is often superior when it comes to the combined overall energy costs of using a separate heater and air conditioner throughout the year.

Finally, they’re generally more expensive and have fewer special features, like Wi-Fi connectivity, than comparable (in terms of British Thermal Units or BTUs) AC-only models. Again, however, the increased upfront cost is offset by the overall energy savings you’ll see using a combination unit rather than two dedicated appliances, like a basic air conditioner and a space heater, but that also depends somewhat on the amount of use they get.

How Window Air Conditioners With Heat Work

Window air conditioners with heat can work in one of two possible ways. Air conditioner/heat pump combination models use the refrigerant cycling method of standard air conditioner models for both their cooling and heating function. To cool air, indoor air is pulled into the unit, while outdoor air is blown inside. The air passes through refrigerant-cooled components and is continuously recycled. For the heating function, a heat pump uses the refrigerant and essentially reverses the process to heat the air.

In supplemental heating models, the refrigerant-cycling method is used only for the cooling function. The heating function is performed by a strip containing an electric heating element, which warms the air the unit’s fan blows across it, somewhat like in portable ventless air conditioners. These often have lower heating speeds than heat pump models.

Why Should You Buy A Window Air Conditioner With Heat?

If you live in a climate with both cold and hot seasons and you have a small garage, workshop, or other space without central air conditioning or heating, a combination model is a wise investment. It eliminates the need to install and uninstall a window AC unit every fall season and saves floor space by removing the need for a portable radiator-style heating unit.

If you have the budget for a high-quality, high-BTU model (with a cooling capacity matched to your room’s square footage) but would like to save on energy costs throughout the year, these models are a great pick. Similarly, if you’re concerned about your carbon footprint, these types of units will lower your overall energy costs.

Lastly, if you live in a mild climate without extreme changes in temperature and humidity or have a space that generally doesn’t need a lot of air conditioning or heating throughout the year, a combination model can be a good all-purpose option that’s efficient and easy to install. For this specific purpose, a supplemental heat model may be a better choice since they’re generally less expensive than the AC/heat pump variety and will perform both functions sufficiently.

Is a Window Air Conditioner With Heat Worth Buying?

  • You have a small space not connected to central air in a variable climate: If you have a small or medium-size room, like a garage or workshop, that’s not connected to central air, this could be a cost-effective option. This is especially true if you live in an area with seasonal temperature extremes.
  • You have a reasonable budget but would like to save on overall energy costs: If your initial budget is generous enough but are concerned about long-term energy costs, a combination AC/heat unit may be a good fit.
  • You have a space that doesn’t require much air conditioning or heating: If you have a space that doesn’t generally get too cool or too hot but want an option for either with minimal installation, combination models can be a good option. And if you’re looking to save a bit of money, a supplemental model would be the best choice between the two variations.
  • You want to save space without sacrificing cooling or heating efficiency: A combination model can be a great way to save space, either on the floor or in multiple windows.
  • You’re short on outlets: A less obvious reason a combination model can be a great pick is if you have a space with limited wall outlets. Provided they can handle the voltage, AC window units with heat can save valuable outlet space.

Why a Window Air Conditioner With Heat May Not Be For You:

  • You’ve got a limited budget: If you’ve got a space with normal or heavy air conditioning needs but less frequent or extreme heating needs, the higher cost of combination models may not be worth their increased efficiency or convenience.
  • You have a space that needs much more cooling than heating: While they’re a great option if you live in an area with temperature extremes or little of either, combination models lose a lot of their usefulness if your cooling needs far outweigh your heating needs, especially considering their higher costs.
  • You’re concerned about noise level: Combination models, especially AC/heat pump units, are often noisier than their standard counterparts due to having more components inside similar-sized chassis.

How Long will a Window Air Conditioner with Heat Last?

Window air conditioners with heat have similar lifespans (10 years) to their single-purpose counterparts. But it really depends on how often they’re used, along with a few other factors:

Climate

Year-long seasonal temperature extremes (where both a hot summer day and below-freezing weather are seasonal possibilities) usually mean more frequent and heavy use for such models. This creates more wear-and-tear, both from increased use and increased temperature changes to the chassis and components.

Direct Sunlight

Just as it does with standard single-purpose models, regular or year-long exposure to direct sunlight can shorten the lifespan of combination models. It will consistently heat the chassis and components, making the unit work harder to perform efficiently and effectively, thus increasing wear-and-tear.

Cleaning and Maintenance

Regularly cleaning or replacing your filter and other components (if possible) will allow the unit to work more effectively since it won’t have clogged filters. Similarly, performing regular maintenance and repairs when necessary means the unit will run smoother, reducing wear-and-tear.

How to Choose a Window Air Conditioner With Heat

Now that you’ve decided to purchase a window air conditioner with heat, you should consider a few additional factors and features that will help you choose the right model for you.

Best Window Air Conditioner With Heat Key Factors

1. How often does your space need air conditioning and heating?

Combination models are often a great product for a small to medium-sized room in areas with mild climates where neither cooling nor heating is needed on a regular basis. They can also be a good backup option if an AC or heating unit fails.

2. How big is your initial budget?

Combination models are generally more expensive than single-use models with comparable BTU output or heating/cooling capabilities. So, a tight budget may make them an impractical option, despite the lower overall energy costs. Keep in mind, though, that supplemental models are usually the cheaper option when it comes to combination units.

3. Are you concerned about floor space?

One of the benefits of a combination model is that they can save on floor space in rooms where a portable heater would often be used alongside a window-install air conditioner.

4. Do you prioritize lower energy costs and carbon footprint?

Very often, the overall energy costs of using a combination model throughout the year are lower than using two dedicated units (a standard AC and a heater, respectively.) With those lower energy costs also comes a smaller carbon footprint, making them a good option overall for the eco-minded consumer. Like standard units, many also have an eco mode or energy-saving mode for increased power savings.

Best Vented Portable Air Conditioner FAQs

Do window air conditioners with heat work well?

Generally speaking, yes. Combination models are effective at both cooling and heating rooms, depending on factors like BTU class and EER rating. However, supplemental varieties, which use a built-in heating element and fan to warm air instead of refrigerant cycling, are generally a little less effective at heating.

Do I need a window air conditioner with heat or a central HVAC system?

Whether a window air conditioner with heat will serve your needs effectively and efficiently compared to a central air conditioner/HVAC system depends on the size of the space and your budget. An HVAC system requires a more extensive installation process and a much higher price than a window unit. The central HVAC system may be the only practical option to cool and heat multiple rooms or a larger room (like an auditorium). Small and medium spaces can usually be effectively served by a window combination unit, and don't require a professional installation.

What is an air conditioner with supplemental heat?

An AC unit with supplement heat uses a compressor, evaporator coil, condenser, and refrigerant for its cooling function and a dedicated heat strip with a heating element for its heating function. When in heating mode, a fan blows air over the heating element to warm the air instead of using the refrigerant cycling method for both heating and cooling. They tend to have fewer operation modes between their two functions and come at a more affordable price.
