10 Best Ways to Lower Your Dominion or Berkeley Electric Bill This Summer

Hot Lowcountry summers mean your AC is running almost constantly, and those energy bills can spike. The plain answer: small adjustments and strategic upgrades can save you $50–$150 per month without sacrificing comfort.

1. Set Your Thermostat Wisely

• Aim for 76–78°F when home and higher when away
• Each degree lower can add 5–10% to your cooling cost
• Use programmable or smart thermostats for automatic adjustments

2. Upgrade to a High-Efficiency AC or Heat Pump

• Older systems lose efficiency over time
• Modern units with high SEER ratings use less electricity for the same cooling
• Consider variable-speed compressors for more consistent temperature and humidity control

3. Maintain Your System

• Replace filters monthly during peak season
• Clear debris around the outdoor condenser
• Schedule a professional tune-up to ensure proper refrigerant levels and airflow

4. Seal and Insulate Ductwork

• Leaky ducts can waste 20–30% of cooled air
• Insulated ducts reduce energy loss in unconditioned spaces like attics or crawlspaces

5. Add Ceiling Fans or Portable Fans

• Fans make you feel cooler without lowering thermostat
• Circulating air lets you set your AC 2–3 degrees higher comfortably
  

6. Limit Heat Gain Inside the Home

• Close blinds or curtains during peak sun hours
• Avoid using ovens or stovetops during the hottest part of the day
• Seal gaps around windows and doors

7. Use a Whole-Home Dehumidifier or AC Dehumidification Settings

• Humidity makes you feel hotter and forces the AC to work harder
• Controlling indoor humidity improves comfort and efficiency

8. Inspect and Upgrade Insulation

• Attic, wall, and crawlspace insulation reduce heat transfer
• Better insulation reduces runtime and lowers bills

9. Schedule Major Electrical Loads Strategically

• Run washers, dryers, and dishwashers during off-peak hours if your utility offers time-of-use pricing
• Avoid running multiple heavy appliances at the same time as your AC

10. Consider Energy-Saving Upgrades

• LED lighting instead of incandescent bulbs
• Smart power strips to reduce phantom loads
• Solar panels or battery-backed energy storage (long-term investment)

Calm Next Step

Start with the simple, low-cost steps like thermostat settings, filters, and fans. If bills are still high, schedule a professional inspection to assess AC efficiency, ductwork, and insulation. A good technician can identify hidden energy drains and help plan cost-effective improvements that keep your home comfortable without overpaying for electricity.
