How to Make Your Home More Energy Efficient in the Quad Cities

At Doug’s Heating & Air Conditioning, we believe home comfort and energy efficiency go hand in hand. Whether you live in Moline, Davenport, Bettendorf, or Rock Island, small upgrades can lead to significant savings. From sealing air leaks to upgrading your HVAC system, there are smart ways to cut costs and boost comfort.

1. Seal Air Leaks & Upgrade Insulation

Drafty windows, doors, or poorly sealed ducts can allow heated or cooled air to escape, wasting energy and money.

• Inspect and seal air leaks around windows, doors, and ductwork.
• Add insulation to attics, crawl spaces, and walls.
• Ensure ductwork is properly sealed and insulated.

This simple step can reduce heating and cooling costs by up to 20%. If your ductwork needs attention, explore our Duct & Dryer Vent Cleaning Services.

2. Upgrade to a High-Efficiency HVAC System

Older HVAC units work harder and use more energy to maintain a comfortable temperature. Replacing outdated equipment with a high-efficiency heating and cooling system can significantly lower your monthly energy bills.

• Look for ENERGY STAR® certified units with high SEER and AFUE ratings.
• Consider switching to a heat pump for year-round efficiency.
• Take advantage of available rebates and tax incentives.

3. Use a Programmable or Smart Thermostat

Smart thermostats help regulate temperature based on your schedule and usage patterns, allowing you to cut energy waste automatically.

• Set temperatures lower at night or when away from home.
• Program energy-saving schedules based on occupancy.
• Control the thermostat remotely with your smartphone.

If your current thermostat is outdated, our team can help with installation and upgrades.

4. Use Ceiling Fans to Improve Air Circulation

Ceiling fans can supplement your HVAC system by distributing air more evenly.

• In the summer, set fans to spin counterclockwise to push cool air down.
• In the winter, reverse the direction to circulate warm air.

This helps maintain comfort while allowing you to raise or lower the thermostat slightly—saving energy without sacrificing comfort.

5. Replace Outdated Appliances and Light Bulbs

Lighting and appliances can consume more energy than you think.

• Replace old incandescent bulbs with LED lighting.
• Choose ENERGY STAR® certified appliances.
• Unplug electronics when not in use or use smart power strips.

6. Maintain Your HVAC System

Routine maintenance is one of the easiest ways to ensure your system runs efficiently.

• Replace air filters every 1–3 months.
• Schedule seasonal maintenance for both heating and cooling units.
• Clean vents, coils, and drain lines regularly.

At Doug’s, we offer convenient maintenance services to keep your system running like new year-round.

7. Improve Water Heating Efficiency

Water heating is the second-largest energy expense in most homes.

• Turn your water heater down to 120°F.
• Fix leaky faucets promptly.
• Consider a high-efficiency water heater if yours is over 10 years old.

These adjustments can reduce your energy usage while ensuring you never run out of hot water when you need it.

8. Consider a Whole-Home Energy Audit

An energy audit gives you a full picture of how your home is performing.

• Identify air leaks, insulation gaps, and inefficient equipment.
• Get expert recommendations tailored to your home.
• Make informed decisions about upgrades that deliver real savings.
