Central Pennsylvania summers bring the kind of heat and humidity that can push your air conditioner into overdrive for months at a time. The good news is that most of the biggest savings opportunities don't require a major renovation. Small habit changes and a few targeted upgrades can add up to a noticeably lower electric bill by the end of the season. Here are 12practical ways to start cutting costs now.
- Unplug Unused Electronics and Turn Off Lights When Not in Use
Devices left plugged in continue to draw power even when they're switched off, a phenomenon often called phantom or standby load. Chargers, TVs, gaming consoles, and small kitchen appliances are common culprits. Get in the habit of unplugging what you're not using, or plug a group of devices into a power strip you can switch off with one flip. Same goes for lights: a room that's empty doesn't need to be lit.
- Optimize Your Fridge
Your refrigerator runs around the clock, which makes it one of the better places to look for savings. Check that the temperature is set correctly (typically 37-40°F for the fridge and 0-5°F for the freezer),and clean the condenser coils on the back or underneath the unit. Dust and pet hair buildup on the coils forces the compressor to work harder to release heat, which means more energy used for the same cooling result.
- Seal Air Leaks
Gaps around windows, doors, attic hatches, and wiring penetrations let hot, humid outside air into your home all summer long, forcing your AC to work harder to compensate. A hand test, a paper test, or a professional blower door test can help identify where you're losing conditioned air. Sealing these leaks is one of the most cost-effective ways to reduce your cooling load.
- Install a Smart Thermostat
A smart thermostat lets you automatically raise the temperature while you're away and bring it back down before you get home, without you having to remember to adjust it manually. Many models also learn your schedule over time and can be controlled remotely from your phone, which is useful if your plans change during the day.
- Maintain Your AC
A well-maintained air conditioner runs more efficiently and is less likely to break down mid-summer. Replace or clean air filters regularly, since a clogged filter restricts airflow and makes the system work harder. It's also worth having a technician check ventilation and refrigerant levels at the start of the season to catch small issues before they become expensive repairs.
- Use Window Coverings
Reflective or light-colored curtains, shades, and blinds can block a significant amount of solar heat before it enters your home, especially on windows that face south or west. Closing coverings during the hottest part of the day is a simple, no-cost habit that reduces the work your AC has to do.
- Choose Energy-Efficient Appliances
When it's time to replace an appliance, look for ENERGY STAR certified models. These are built to use less electricity than standard models while performing the same job, and the savings compound over the life of the appliance.
- Use Energy-Efficient Landscaping
Shade trees and shrubs planted strategically around your home, particularly on the south and west sides, can block direct sun before it heats up your walls and windows. Over time, mature shade trees can meaningfully lower the temperature immediately around your house, which reduces how hard your AC needs to work.
- Run Laundry and Dishes During Off-Peak Hours
Many utility providers charge more for electricity during peak demand hours, typically in the late afternoon and early evening when everyone's AC is running at once. Shifting laundry and dishwasher loads to late evening or early morning can lower your costs if your utility offers time-of-use rates, and it also avoids adding extra heat to your home during the hottest part of the day.
- Use Ceiling Fans
Ceiling fans don't actually cool a room, they cool the people in it by creating a wind chill effect. Running fans alongside your AC lets you raise the thermostat a few degrees without sacrificing comfort, which reduces how often your AC cycles on. Just remember to turn fans off when you leave a room, since they don't do any good cooling an empty space.
- Add or Upgrade Insulation
Insulation slows the transfer of heat into your home, which directly reduces how hard your AC has to work to keep up. Attics are typically the highest-impact area to address, since heat gain through an under-insulated attic can affect the whole house. If your home has visible gaps, thin insulation, or rooms that never seem to cool down properly, it maybe time for an upgrade.
- Grill Outdoors Instead of Heating Up the Kitchen
Ovens and stovetops add heat and humidity directly into your living space, which your AC then has to remove .Moving meal prep outside to a grill during the summer keeps that heat where it belongs, outside, and can noticeably ease the load on your cooling system on hot days.
