Your through-the-wall AC, such as the Amana 9,300 BTU PBC093J00AA, can consume a significant amount of energy during peak summer months. However, with proper setup, habits, and maintenance, you can reduce your energy use by 20-40% while keeping your living space comfortable.
This comprehensive guide will cover: ✅ Pre-installation steps to boost efficiency.
✅ Smart usage strategies.
✅ Maintenance practices for optimal performance.
✅ Upgrades and accessories to enhance efficiency.
✅ How to monitor and lower energy costs sustainably.
🏗️ 1. Pre-Installation Steps for Maximum Efficiency
Proper Sizing
An oversized unit short-cycles, wasting energy, while an undersized unit struggles to cool the space efficiently.
Use the Energy Star AC Sizing Calculator to match your room size, insulation, and climate zone with the appropriate BTUs.
Location Matters
Install your unit on the shadiest side of your home to reduce heat gain. Avoid areas where heat-producing appliances or direct sunlight will affect your AC’s thermostat.
Seal and Insulate
Before installation:
✅ Weatherstrip doors and windows.
✅ Seal air leaks around the unit and within the room.
✅ Insulate walls and ceilings for better climate control.
See EPA's Home Sealing Guide for detailed steps.
Use the Correct Wall Sleeve
Ensure your AC is installed in a compatible wall sleeve with a proper rear grille, allowing efficient airflow and drainage. Learn more in Wall Sleeve Guide.
🌞 2. Daily Usage Habits to Save Energy
Set the Right Temperature
The U.S. Department of Energy recommends 78°F (26°C) as an optimal cooling temperature when you are home and higher when away. Every degree lower increases energy use by 3-5%.
Use Energy-Saving Modes
Most modern through-the-wall ACs feature "Eco Mode" or "Energy Saver Mode," which cycles the fan and compressor to maintain temperatures efficiently.
Block Heat During the Day
✅ Use blackout curtains or shades on sunny windows.
✅ Apply reflective window film to reduce solar heat gain.
✅ Close windows and doors during peak heat hours.
Learn about reducing heat gain with Energy Saver’s Cooling Strategies.
Supplement with Ceiling or Box Fans
Fans improve air circulation, allowing you to set your AC 2-4 degrees higher without sacrificing comfort.
🧽 3. Regular Maintenance for Optimal Performance
Clean or Replace Air Filters
Dirty filters block airflow, causing the system to work harder. Clean filters every 30 days during heavy use, or replace them if damaged.
Refer to Amana's Filter Maintenance Guide for specific instructions.
Inspect and Clean Coils
Dirty coils reduce heat transfer efficiency. Clean evaporator and condenser coils seasonally or more frequently in dusty environments.
Use the Family Handyman Coil Cleaning Guide for DIY tips.
Check and Maintain Proper Drainage
A clogged drain can cause leaks and humidity issues. Ensure the unit is slightly tilted backward (1/4 inch) for effective drainage.
Check Seals and Insulation
Inspect the seal between the AC and wall sleeve annually to ensure no air leaks. Reapply weatherstripping or caulking as needed.

⚙️ 4. Smart Upgrades and Accessories
Programmable Thermostats
Some through-the-wall ACs are compatible with programmable or smart thermostats, allowing you to:
✅ Schedule cooling cycles around occupancy.
✅ Control the unit remotely.
✅ Optimize cooling while reducing energy use.
Smart Plugs and Energy Monitors
Use smart plugs with energy monitoring to track usage patterns and identify inefficiencies.
Insulated Wall Sleeves
Upgrade to a high-quality, insulated wall sleeve to reduce heat exchange with the outdoors and dampen noise..
💡 5. Advanced Strategies to Reduce Energy Use
Zone Cooling
Cool only occupied rooms instead of the entire home, using your through-the-wall unit for targeted cooling while reducing reliance on central AC.
Night Cooling
If your climate allows, turn off the AC at night and use fans with open windows to cool the room naturally.
Dehumidify When Necessary
High humidity makes it feel warmer, prompting lower thermostat settings. Use your AC’s "Dry Mode" or a standalone dehumidifier to maintain comfort while reducing cooling demand.
Learn more about humidity management with EPA's Indoor Humidity Guide.
💸 6. Track and Lower Your Energy Bills
Use Utility Apps and Tools
Many utility providers offer energy monitoring tools to track usage and costs.
Compare Your Unit's Efficiency
Check your unit’s Energy Efficiency Ratio (EER) and compare it with ENERGY STAR-rated models on the ENERGY STAR Product Finder.
Look for Rebates and Incentives
Rebates can offset the cost of efficient units. Check DSIRE for federal, state, and local incentive programs.
Conduct a Home Energy Audit
A professional audit identifies insulation gaps, air leaks, and other inefficiencies. Learn more from Energy Saver’s Home Energy Audit Guide.
🧩 FAQs About Saving Energy with Through-the-Wall ACs
Is "Eco Mode" worth using?
Yes. Eco Mode reduces compressor runtime by maintaining temperatures within a comfortable range while saving energy.
Should I turn off my AC when leaving home?
If you’re away for extended periods, turning off your AC saves energy. For shorter periods, raise the thermostat to reduce usage while preventing humidity buildup.
Can I use solar energy to power my AC?
While through-the-wall ACs require consistent power, pairing them with a solar system and battery storage can offset energy costs, depending on your system size.
📝 Final Efficiency Checklist
✅ Correctly size and position your AC.
✅ Seal and insulate your home and wall sleeve.
✅ Set your thermostat to 78°F during summer.
✅ Use fans to supplement cooling.
✅ Clean filters and coils regularly.
✅ Use "Eco Mode" when possible.
✅ Track and monitor energy use.
✅ Look for rebates and incentives.
