Living in Mount Pleasant, SC, means enjoying warm coastal weather for most of the year—but it also means high energy bills, especially during the peak of summer. Keeping your home cool and comfortable doesn’t have to come at the expense of sky-high utility costs. With a few innovative HVAC strategies, you can effectively reduce energy usage without sacrificing comfort.
At Dunes Heating and Air Conditioning, we help homeowners maximize efficiency while keeping their homes comfortable year-round. Here are some practical ways to lower your energy bills in Mount Pleasant without compromising your indoor climate.
1. Upgrade to a Smart Thermostat
Installing a smart thermostat is one of the easiest ways to save energy. These devices automatically adjust your home’s temperature based on your schedule and habits, ensuring your HVAC system isn’t running unnecessarily.
- Set your thermostat higher when you’re away in the summer and lower in the winter.
- Use programmable schedules to cool or heat your home efficiently.
- Many smart thermostats can be controlled via an app, allowing you to make adjustments remotely.
Pro Tip: For optimal efficiency, the U.S. Department of Energy recommends setting your thermostat to 78°F in summer and 68°F in winter when you’re home.
2. Use Ceiling Fans to Reduce HVAC Strain
Ceiling fans help circulate air throughout your home, making rooms feel cooler without overworking your air conditioner. In summer, set your ceiling fans to rotate counterclockwise to push cool air down. In winter, switch them to clockwise to distribute warm air.
- Running a ceiling fan allows you to raise your thermostat setting by 4°F without noticing a change in comfort.
- Turn fans off when leaving a room—fans cool people, not the air itself.
3. Seal Air Leaks and Improve Insulation
Poor insulation and air leaks around doors and windows can cause your HVAC system to work harder than necessary. Sealing these leaks and improving insulation helps keep conditioned air inside where it belongs.
- Use weatherstripping or caulk to seal gaps around windows and doors.
- Insulate attics, crawl spaces, and ductwork to prevent heat loss in winter and keep cool air in during summer.
- Check for drafts and seal any cracks in your home’s foundation.
4. Schedule Regular HVAC Maintenance
A well-maintained HVAC system runs more efficiently, reducing energy consumption and preventing costly breakdowns. Preventive maintenance ensures your system is working at peak performance.
- Change air filters every 1-3 months to improve airflow and efficiency.
- Have your HVAC system professionally tuned up twice yearly—once before summer and once before winter.
- Clean evaporator and condenser coils to remove dust and debris that can reduce efficiency.
Pro Tip: According to ENERGY STAR, regular maintenance can lower your energy consumption by up to 15%.
5. Reduce Heat Gain from the Sun
The South Carolina sun can make your air conditioner work overtime. Reduce indoor heat gain by:
- Closing blinds or curtains during peak sunlight hours, especially on south-facing windows.
- Installing energy-efficient window films or shades to block out heat.
- Use landscaping like trees and shrubs to provide natural shade around your home.
6. Use Energy-Efficient Appliances & Lighting
Your home’s appliances, lighting, and electronics contribute to your overall energy usage. Switching to ENERGY STAR-rated appliances and LED light bulbs can make a noticeable difference.
- Replace incandescent bulbs with LEDs, which use 75% less energy.
- Unplug electronics or use smart power strips to prevent energy waste from devices in standby mode.
- Run large appliances (like dishwashers and dryers) in the evening to reduce strain on your HVAC system during peak heat hours.
7. Optimize Your AC Usage
Your air conditioning unit is likely the most significant contributor to your energy bill. Optimizing how and when you use it can lead to significant savings.
- Keep interior doors and vents open to maintain consistent airflow.
- Avoid setting your thermostat too low—each degree below 78°F can increase cooling costs by up to 8%.
- Consider zoning systems for multi-story homes to cool only the areas that need it.
8. Consider an HVAC Upgrade
If your heating and cooling system is over 10-15 years old, it may be time for an upgrade. Newer, high-efficiency models can cut energy costs by up to 30%.
- Look for ENERGY STAR-rated HVAC systems for the best efficiency.
- Consider ductless mini-splits if you only need to cool or heat specific rooms.
- Ask about variable-speed systems, which adjust output based on real-time needs instead of running at full blast all the time.
