7 Ways to Reduce HVAC Energy Use and Save Money

Are you looking to cut your home energy bills? Your heating, ventilation, and air conditioning (HVAC) system is one of the biggest residential energy users. Check these ten simple HVAC energy-saving tips to slash costs without sacrificing comfort.

1. Change HVAC Filters Regularly

One of the easiest and most effective ways to save energy is by regularly changing your HVAC filters. Dirty filters force your system to work harder, restricting airflow and reducing efficiency. When air can’t circulate properly, your system uses more power to maintain comfortable temperatures. Replacing filters every 1-3 months can help maintain optimal airflow and reduce wasted energy.

2. Schedule an Annual HVAC Tune-Up

Like your car, your HVAC system needs regular maintenance to perform at its best. An annual tune-up by a qualified HVAC technician is a great way to ensure your system is running efficiently. During a tune-up, the technician will:

  • Check refrigerant levels
  • Ensure ductwork is properly sealed
  • Diagnose and replace worn parts

This thorough inspection and maintenance routine helps prevent minor issues from becoming costly repairs. This will not only extend the life of your system but also help it run more efficiently, leading to energy savings throughout the year.

3. Adjust Thermostat Set Points

The thermostat is your control center for energy savings. Adjusting your thermostat set points when you’re home and away can dramatically reduce energy consumption. Here are some suggested thermostat settings:

  • Heating: 68°F when home / 60-65°F when away
  • Cooling: 78°F when home / 82-85°F when away

For even more convenience, consider investing in a programmable or smart thermostat. These devices allow you to set heating and cooling schedules that automatically adjust based on your daily routine. Smart thermostats can learn your habits and make real-time adjustments to maximize comfort and efficiency.

4. Upgrade Insulation

Proper insulation is essential for maintaining your home’s temperature and reducing the load on your HVAC system. Heat or cooled air escapes without proper insulation, forcing your HVAC system to work harder to maintain your desired temperature. Insulating your attic, walls, basement, and crawl spaces can save energy.

5. Install an ENERGY STAR Certified HVAC System

If your HVAC system is over ten years old, it might be time for an upgrade. Older systems are less efficient and may cost you more than you realize. Replacing your outdated system with a new, ENERGY STAR-certified model can reduce energy use by up to 20% or more. New HVAC systems are designed to use energy more efficiently while maintaining comfort. In addition, newer models come equipped with advanced technology that makes them easier to control and maintain. By choosing an ENERGY STAR system, you’re making a long-term investment in both comfort and savings.

6. Use Zoned Control

Zoned HVAC systems are a game-changer for energy savings. Instead of heating or cooling your entire home, you can set different temperatures for different areas or zones based on occupancy. This means you can heat or cool only the areas you use, reducing unnecessary energy use. If your home has multiple levels, a zoned HVAC system can help balance temperatures throughout the house, providing more comfort and control. Additionally, closing vents in rooms you rarely use ensures that air is directed to the areas that need it most.

7. Adjust Fan Settings

Your HVAC system’s fan settings can significantly impact energy consumption. It’s best to set your fan to “auto” mode in the summer, which will only run when your system is actively cooling. This prevents the fan from running continuously, saving energy. In the winter, briefly setting the fan to “on” mode can help distribute heated air more evenly throughout your home. This simple adjustment ensures that all rooms are heated consistently without wasting energy on unnecessary fan operation.

Maximize Your Savings

These tips can significantly reduce your HVAC energy use and lower home energy bills. Whether performing regular maintenance, upgrading your insulation, or investing in a new HVAC system, each step contributes to a more energy-efficient and comfortable home. Remember to take advantage of rebates and tax credits when upgrading your system. With the right maintenance and smart usage, your HVAC system will run more efficiently and help you save money for years.
