⚡ What Is EER and Why Does It Matter?
EER (Energy Efficiency Ratio) measures how efficiently an air conditioner uses electricity to cool a space.
A higher EER means your unit provides more cooling per watt consumed, lowering your electricity bills while keeping your home comfortable.
The U.S. Department of Energy recommends choosing higher EER units to save energy and reduce environmental impact.
❄️ Amana PBE123J35AA EER Overview
The Amana 11,900 BTU Through-the-Wall AC with Electric Heat (PBE123J35AA) offers a high EER rating, making it an energy-efficient choice for:
-
Bedrooms
-
Living rooms
-
Offices
-
Small apartments
Its efficient design ensures reliable cooling while reducing electricity consumption, aligning with Mike Sanders' practical homeowner approach to long-term savings.
💡 How EER Impacts Your Energy Bills
Consider this example:
-
A unit with an EER of 10 vs. one with an EER of 8 will use 20% less electricity to provide the same cooling.
-
If cooling costs are $60 per month with an EER 8 unit, using an EER 10 unit could save around $12 per month.
-
Over five years, this can save you $720 or more, depending on usage and local rates.
The Energy Star program offers tools to estimate savings with high-efficiency units.
🏠 Factors That Affect Energy Efficiency
1️⃣ Room Size and Insulation: Proper sizing ensures your AC isn't overworked.
2️⃣ Sun Exposure: Rooms with heavy sunlight require more cooling power, slightly increasing energy use.
3️⃣ Air Leaks: Sealing leaks around windows, doors, and the AC sleeve improves efficiency.
4️⃣ Filter Maintenance: Clean filters improve airflow and reduce strain on your unit.
5️⃣ Thermostat Use: Setting the thermostat to a reasonable temperature reduces energy waste.
🧰 Tips to Maximize Efficiency with Your Amana AC
✅ Clean Filters Monthly: Improves airflow and efficiency.
✅ Use Curtains or Blinds: Reduce heat gain in sunny rooms.
✅ Seal Air Leaks: Around the AC and doors/windows.
✅ Install a Programmable Thermostat: To reduce runtime when not needed.
✅ Regular Coil Cleaning: To maintain heat transfer efficiency.
Following these practices aligns with the DOE’s guide for reducing energy use while maintaining comfort.
🌡️ Understanding Supplemental Heat and Energy Use
The Amana unit includes electric heat, which is resistance heating:
-
Converts electricity directly into heat (nearly 100% efficient at the source)
-
Typically more costly per BTU than cooling
-
Best used for supplemental or emergency heating rather than primary heating
Use the heating function strategically to avoid high electricity costs during winter months.
🔋 Environmental Benefits of High-Efficiency ACs
Using a high EER unit helps reduce:
-
Greenhouse gas emissions
-
Power plant demand during peak hours
-
Environmental strain from excessive energy consumption
As noted by Energy Star, energy-efficient units contribute to a more sustainable household.
💲 Is an Energy-Efficient AC Worth the Investment?
Although high-EER units like the Amana PBE123J35AA may have a higher upfront cost, they offer:
-
Lower monthly energy bills
-
Reduced environmental impact
-
Long-term cost savings
-
Quieter, more effective operation
Over the lifespan of your unit (10–15 years), the savings typically outweigh the initial higher cost, making it a smart investment for practical homeowners.
✅ Final Takeaway: Efficiency That Pays Off
Choosing a high-efficiency, high-EER through-the-wall AC like the Amana 11,900 BTU PBE123J35AA ensures:
-
Lower energy bills
-
Reliable cooling performance
-
Reduced environmental footprint
-
Long-term value for your home
