💲 Why Understanding Operating Costs Matters
Knowing the true cost of running your Amana 11,900 BTU Through-the-Wall AC with Electric Heat (PBE123J35AA) helps homeowners like Mike Sanders:
-
Budget accurately for summer and shoulder seasons
-
Compare costs with window ACs or central systems
-
Optimize usage for energy savings
The U.S. Department of Energy emphasizes understanding appliance energy use to reduce unnecessary expenses while maintaining comfort.
⚡ Key Factors Impacting Operating Costs
1️⃣ Energy Efficiency (EER): Higher EER units use less electricity.
2️⃣ Local Electricity Rates: Average rates vary from $0.10 to $0.30 per kWh in the U.S.
3️⃣ Usage Hours: Daily and seasonal runtime.
4️⃣ Thermostat Settings: Lower settings use more power.
5️⃣ Room Conditions: Insulation and sun exposure affect runtime.
6️⃣ Filter and Coil Maintenance: Clean units operate efficiently, reducing costs.
📊 Estimated Cooling Costs
The Amana PBE123J35AA typically consumes around 1,000–1,100 watts per hour while cooling.
At $0.15 per kWh:
-
Hourly: $0.15–$0.17
-
8 hours/day: $1.20–$1.36
-
30 days: $36–$41
-
Full season (4 months): $144–$164
Using programmable thermostats and ceiling fans can further lower runtime and costs.

♨️ Electric Heat Operating Costs
The electric heat function on the Amana unit uses approximately 1,500 watts per hour.
At $0.15 per kWh:
-
Hourly: $0.23
-
4 hours/day (shoulder seasons): $0.92
-
30 days: $27.60
-
2 months seasonal use: $55
Because resistance heat is more expensive per BTU than gas or heat pump systems, it is best used for targeted, supplemental heating rather than as a primary heat source.
🛠️ How to Reduce Operating Costs
✅ Clean filters monthly for unrestricted airflow. ✅ Seal air leaks around windows and doors. ✅ Use ceiling fans to circulate cool air. ✅ Install a programmable thermostat to optimize runtime. ✅ Close blinds or curtains to reduce heat gain in summer. ✅ Set the thermostat to 78°F when home, 85°F when away (per DOE recommendations).
Following Energy Saver guidelines can lower your cooling bills by up to 10% annually.
🧮 Comparing Costs: Amana vs. Window AC vs. Central AC
| Feature | Amana Through-the-Wall AC | Window AC | Central AC |
|---|---|---|---|
| Installation | Permanent | Temporary | Whole-house |
| Efficiency | High (EER) | Moderate | Varies (SEER) |
| Operation Cost (room) | Low | Low | Higher for single-room use |
| Noise | Low | Moderate | Low |
| Flexibility | Room-specific | Room-specific | Whole-house |
For cooling one or two rooms, a high-efficiency through-the-wall AC often offers the lowest operational cost with long-term stability, especially when replacing older window units.
✅ Is It Cost-Effective for Your Home?
Using the Amana through-the-wall AC is cost-effective if you:
-
Primarily need to cool specific rooms
-
Want to avoid cooling the entire home unnecessarily
-
Seek high efficiency for lower utility bills
-
Need a heating option for shoulder seasons without relying on central heat
🏡 Real-World Mike Sanders Example
Mike uses his Amana PBE123J35AA in a 450 sq ft home office:
-
Runs 8 hours/day during peak summer.
-
Sees an estimated $40/month increase in electricity, much lower than using the central system.
-
Uses electric heat for 2 hours in the morning during fall for under $15/month.
-
Finds the system affordable, efficient, and effective for targeted comfort.
