What’s the Most Energy-Efficient Way to Heat My Home?
Every fall, homeowners across Missouri ask the same question: What’s the best way to heat my home without spending a fortune?
The answer depends on your home’s size, insulation, and system age, but one thing is certain: modern HVAC systems can save you hundreds each year when installed and maintained correctly.
Here’s how to choose the most energy-efficient heating setup for your Chesterfield home.
1. Upgrade to a High-Efficiency Furnace
If your furnace is more than 10–15 years old, it’s probably operating at 70–80% efficiency, which means up to 30% of your energy is wasted.
Today’s high-efficiency gas furnaces reach AFUE ratings of 95–98%, turning nearly every bit of fuel into heat.
✅ Benefits:
Lower monthly gas bills
Even heating across all rooms
Quieter operation and improved airflow
🧠 Pro Tip: Choose an ENERGY STAR®-certified model and pair it with a programmable thermostat for maximum efficiency.
2. Consider a Heat Pump for Mild Missouri Winters
Heat pumps have become one of the most energy-efficient ways to heat and cool homes, especially in climates like Missouri’s, where winters are cold but not extreme.
A heat pump transfers heat instead of generating it, using up to three times less energy than a traditional furnace.
💡 Bonus: Heat pumps double as air conditioners in summer, giving you year-round comfort from a single system.
✅ Best for:
Homes with moderate winter temperatures
All-electric households
Homeowners looking to reduce carbon footprint
3. Don’t Overlook Insulation and Ductwork
Even the most efficient system can’t perform if your home leaks heat.
In older Chesterfield homes, air leaks around windows, attic access panels, and duct joints are common energy drains.
🏠 Efficiency Boost Checklist:
Seal duct leaks with mastic or foil tape
Add attic insulation to R-49 or higher
Install weather stripping around doors and windows
You’ll feel the difference in comfort and your utility bill.
4. Schedule Regular HVAC Maintenance
Routine tune-ups keep your system running at peak efficiency. A dirty filter or clogged coil can raise energy use by 10–15%.
During a fall furnace inspection, your Fresh Air technician will:
Clean burners and ignition components
Check gas pressure and airflow
Calibrate the thermostat
Inspect safety switches and sensors
🛠️ Maintenance Tip: Replace filters every 1–3 months, especially during heavy use.
5. Use Smart Thermostats Wisely
Smart thermostats like Nest or Ecobee can reduce heating costs by learning your habits.
Set schedules around your lifestyle: lower temps at night or when away, then warm up just before you wake or return.
💡 Pro Tip: Each degree you lower your thermostat for eight hours can save up to 3% on your heating bill.
