How to Lower Your HVAC Energy Bill Without Sacrificing Comfort

Texans know that heating and cooling systems run year-round—especially during intense summers and chilly winters. With HVAC usage being one of the biggest contributors to your utility bill, it’s no surprise that homeowners and businesses want to cut costs without compromising comfort.

At Tarrant Mechanical, we help DFW residents and businesses improve energy efficiency with expert HVAC guidance. Here are our top tips for lowering your HVAC energy bill while keeping your home or building perfectly comfortable.

1. Schedule Regular HVAC Maintenance

Routine HVAC maintenance ensures your system runs efficiently all year long. A well-maintained system:

• Uses less energy
• Experiences fewer breakdowns
• Lasts longer
• Maintains better air quality

Tip: Schedule spring and fall tune-ups with a trusted HVAC company like Tarrant Mechanical.

2. Upgrade to a Programmable or Smart Thermostat

A programmable thermostat adjusts the temperature based on your schedule. A smart thermostat goes even further by learning your habits and optimizing settings automatically.

This small upgrade can result in major savings—up to 10% annually on heating and cooling costs.

3. Change Air Filters Regularly

Dirty filters restrict airflow, making your HVAC system work harder. Changing them every 1–3 months:

• Reduces strain on your system
• Improves airflow
• Lowers energy usage

This is one of the simplest and most cost-effective energy-saving steps.

4. Seal Air Leaks and Insulate Properly

Air leaks around doors, windows, and ductwork let conditioned air escape and force your system to run longer. Proper insulation and sealing:

• Reduces wasted energy
• Keeps indoor temps stable
• Lowers heating and cooling demand

Check your attic, walls, and ducts for proper insulation and sealing.

5. Use Ceiling Fans to Improve Air Circulation

Fans help distribute cool or warm air more evenly, reducing the load on your HVAC system. In summer, set fans to rotate counterclockwise; in winter, reverse them.

Fans don’t lower the temperature, but they help you feel more comfortable, allowing you to set your thermostat a few degrees higher or lower.

6. Close Blinds and Curtains During Peak Heat

Texas summers bring intense sunshine. Closing your blinds or curtains during the hottest parts of the day can block heat gain and reduce the load on your air conditioner.

Bonus: It helps protect furniture and floors from UV damage.

7. Consider a System Upgrade

Older HVAC systems (10+ years) are far less efficient than modern models. If your system is outdated, upgrading to an energy-efficient unit with a high SEER rating can lower your monthly bill significantly.

Tarrant Mechanical offers expert guidance and installation for homeowners and businesses looking to invest in long-term savings.

8. Keep Vents Open and Unobstructed

Contrary to popular belief, closing vents in unused rooms can disrupt airflow and reduce efficiency. Instead, keep vents open and free of furniture or rugs to allow balanced airflow throughout the home.
