If you’re a homeowner in Middle Tennessee, especially in neighborhoods like Brentwood, Franklin, Nashville, Murfreesboro, Mount Juliet, Nolensville, Old Hickory, Hendersonville, Goodlettsville, Columbia, Thompson’s Station, Smyrna, La Vergne, Fairview, Dickson, Bellevue, Antioch, Hermitage, Donelson, or Lebanon—you’ve likely noticed the pain of rising energy bills. One major reason? Unsealed attics and crawl spaces.

Here’s why air sealing these areas is one of the smartest home improvements you can make:

How Much Energy Is Being Lost?

• The U.S. Department of Energy estimates that up to 25% of heat loss occurs through the attic when it’s improperly sealed or under insulated.
• Combine this with crawl spaces, and you’re potentially losing up to 30% of your home’s energy just through leakage and poor insulation in these areas.
• According to the EPA, proper air sealing and insulation can save 15% on heating and cooling costs and 11% on total energy use.

If you live in Franklin, Mount Juliet, or Smyrna, that could mean hundreds in annual savings—especially during those hot Middle Tennessee summers and chilly winters.

Crawl Spaces Are a Hidden Culprit

In areas like Columbia, Nolensville, and Dickson, many homes have vented crawl spaces that pull in hot, humid air in summer and cold, damp air in winter. This not only hurts energy efficiency but can create serious air quality and moisture problems.

Benefits of sealing your crawl space in Middle Tennessee include:

• Lower humidity levels
• Reduced risk of mold and pests
• 15–18% HVAC energy savings
• Cleaner, healthier air—especially important for families in allergy-prone cities like Old Hickory, Fairview, and Hendersonville

 Ducts in Attics & Crawl Spaces = More Waste

Many homes across Antioch, La Vergne, and Lebanon have HVAC ductwork running through unconditioned attics or crawl spaces. If those areas aren’t sealed and insulated, you’re likely losing 25–40% of your heating or cooling energy through duct leaks alone.

 Top Benefits of Air Sealing for Middle Tennessee Homes

1. Lower Energy Bills — Whether you’re in Brentwood or Bellevue, better sealing means lower monthly bills.
2. Increased Comfort — No more hot upstairs bedrooms or freezing cold floors in your Hermitage or Donelson home.
3. Improved Air Quality — Especially in crawl-space-heavy homes in Thompson’s Station or Smyrna.
4. Longer HVAC Lifespan — Sealed systems work less and last longer—ideal for homeowners across the region.
5. Higher Home Value — Efficient homes in Middle Tennessee neighborhoods sell faster and for more.
