🌡️ Electric Heat Built In — What It Means for Year-Round Comfort

When you live in a climate where summers feel endless but winter sneaks up with a chill, having a cooling system that can also heat your space just makes sense. That’s exactly what makes Amana’s through-the-wall units with electric heat so versatile.

They cool efficiently in the summer, take the edge off winter mornings, and keep you comfortable without needing two separate systems. In this guide, we’ll unpack everything you need to know about built-in electric heat—from how it works and when to use it, to the real-world advantages it offers for year-round comfort.

⚙️ How Electric Heat Works Inside a Through-the-Wall AC

At the heart of Amana’s design is a heating element, much like what you’d find in a space heater—but built right into your air conditioner. When you switch to heating mode, the unit redirects electrical current to a metal coil. That coil heats up, and your fan pushes air over it, sending warm air throughout your room.

Unlike heat pumps, which transfer heat from outside air, electric resistance heating actually creates heat. That means it’s dependable even when outdoor temperatures drop below freezing—perfect for mild to moderately cold climates.

According to the U.S. Department of Energy, electric heat offers instant, steady warmth because it converts nearly 100% of the electricity it consumes into heat.

🧊 Cooling + 🔥 Heating = True All-Season Control

If you’ve ever used a traditional window AC or portable unit, you know the trade-off: you get cooling, but when temperatures drop, you’re on your own. A through-the-wall unit with integrated electric heat changes that.

With one appliance, you can:

• Cool in the summer — using the compressor and refrigerant system.

• Heat in the winter — using the built-in resistance heater.

• Dehumidify during shoulder seasons — removing excess moisture to keep indoor air balanced.

This dual-function setup means you don’t have to swap systems or store seasonal units. It’s a permanent, efficient solution for consistent comfort.

For multi-family buildings or retrofits, this is especially valuable—tenants or homeowners get both heating and cooling without needing ducts or expensive infrastructure upgrades.

🏠 Ideal Use Cases: When Built-In Electric Heat Shines

1. Apartments and Condos

Compact living spaces benefit from space-saving, wall-mounted systems that don’t interfere with windows or need exterior compressors.

2. Home Additions and Garages

Electric heat is perfect for newly finished basements, sunrooms, or garage conversions, where central HVAC may not reach.

3. Vacation Rentals and Guest Suites

Guests can easily control their own temperature—no need to mess with the home’s main thermostat.

4. Small Businesses or Offices

From salons to small offices, a built-in heating element keeps your workspace comfortable year-round with no floor clutter.

Amana’s lineup, including the PBE123J35AA 11,900 BTU model, delivers targeted comfort where you need it most.

⚡ Why Electric Heat Is So Reliable

Electric resistance heating is mechanically simple—no refrigerant switching or compressors needed. The system relies on metal coils that generate heat instantly when powered. This simplicity means:

• Fewer moving parts = fewer repairs.

• Immediate heat delivery = faster comfort.

• 100% indoor installation = no outdoor exposure or winterization needed.

As the Electric Power Research Institute notes, resistance heating systems are among the most dependable forms of electric comfort heat available today, offering long-term stability with minimal maintenance.

💰 Energy Use and Efficiency: What to Expect

Electric heat is nearly 100% efficient at converting energy into warmth, but that doesn’t always mean it’s the most cost-effective option—especially in regions with high electricity rates.

That said, Amana’s hybrid through-the-wall systems are designed for targeted heating, not whole-home coverage. Instead of heating every square foot, you’re focusing warmth exactly where it’s needed—like a bedroom, office, or apartment suite.

To make it even more efficient:

• Use a programmable thermostat to maintain consistent comfort.

• Pair your unit with Energy Star-rated insulation and windows (Energy Star recommendations).

• Set heating mode to 68°F when occupied and slightly lower when you’re away, following DOE’s comfort guidelines.

This targeted approach can result in significant annual savings, especially compared to central systems that heat unoccupied zones.

🧠 The Difference Between Electric Heat and Heat Pumps

It’s easy to confuse electric heat with heat pump technology—but they operate differently.

If you live in a region where temperatures dip below 40°F, an electric-heated wall unit offers consistent performance when a heat pump might struggle.

According to ENERGY.gov, heat pumps are ideal for moderate climates, but for cooler regions, electric backup is often recommended—which is exactly what’s built into the Amana PBE123J35AA.

🧩 Built-In Electric Heat = Simplified Installation

One of the main benefits of Amana’s integrated electric heater is ease of setup. You don’t need separate heating circuits or ductwork. Once your wall sleeve is installed, the unit simply plugs into the appropriate 230/208V connection.

You’ll get:

• All-season functionality in one compact system.

• Clean wall integration—no bulky baseboards or space heaters.

• Remote control convenience for quick mode switching.

If you’re planning to DIY your install, make sure to review your local electrical code and match your power receptacle to the model’s rating. For safety and warranty protection, Amana recommends professional verification of the final electrical connection.

🧽 Maintenance Tips for Electric-Heat Units

Even though these systems are low-maintenance, regular care keeps them efficient year after year.

🧼 1. Clean or Replace Filters Monthly

Dust buildup restricts airflow, making both cooling and heating less effective.

💧 2. Check Drain Pans and Coils

Keep condensation areas clean to avoid mold or odors.

⚙️ 3. Inspect the Heating Element Seasonally

Before switching to “heat” mode each fall, test the system briefly to ensure the element glows and the fan distributes warm air.

🧯 4. Verify Electrical Connections

If you notice tripped breakers or inconsistent heating, have an electrician inspect the wiring and outlet amperage.

Amana units are designed for easy access to filters and coils, minimizing service time and costs.

🧊 Smart Controls for Year-Round Comfort

Modern Amana wall units, like the PBE123J35AA, come with digital displays and remote controls that let you:

• Adjust temperature modes instantly.

• Switch from cool to heat without reinstallation.

• Use energy-saving features like sleep mode or fan-only cycles.

If you want more control, you can pair your unit with a Wi-Fi-enabled smart plug or thermostat, allowing app-based scheduling and remote temperature checks.

For best results, consider devices certified under the EPA’s Connected Thermostat Program, which helps manage comfort while cutting energy waste.

🌎 Environmental Impact: Cleaner Heating for the Future

Electric heating technology has evolved dramatically in recent years. With the rise of renewable power sources and stricter efficiency standards, electric heat is becoming a cleaner, greener option.

When powered by solar or other renewable sources, the carbon footprint of electric heat drops significantly. According to the International Energy Agency (IEA), the electrification of heating systems is one of the most effective ways to cut emissions in residential spaces.

For eco-conscious homeowners, pairing an Amana through-the-wall unit with renewable energy or time-of-use rate plans can deliver real sustainability benefits—without sacrificing comfort.

🧮 Cost Breakdown: What You’ll Actually Spend

Let’s talk numbers.

While electric heat isn’t always the cheapest to run, the low upfront cost and simplicity often make it the most practical choice for smaller zones.

And unlike portable or space heaters, Amana’s system provides even, thermostatically controlled warmth that’s built into your wall—safe, efficient, and stylish.
