Your HVAC system can only do so much if your home is leaking air like a sieve. In Northwest Georgia, the combination of hot, humid summers and occasional cold winters makes proper insulation and air sealing one of the highest-ROI home improvements you can make.

At Anderson Heating, Air & Insulation (formerly John Anderson Service Company), we've been BPI Certified for years because we understand that HVAC is only part of the equation. The house matters just as much.

The Hidden Cost of Poor Insulation

Most homes in Calhoun, Dalton, Rome, and surrounding areas were built before modern energy codes. Many have R-19 or less in the attic — far below the R-49 to R-60 recommended for our climate zone.

When you combine that with air leaks around recessed lights, pipes, electrical boxes, and the attic hatch, your home can lose conditioned air equivalent to a 3x3 foot hole in the wall. Your HVAC has to work twice as hard, your bills go up, and your comfort goes down.

What BPI-Certified Air Sealing Actually Does

Unlike basic insulation companies, we use advanced techniques:

  • Blower door testing to measure exact air leakage
  • Infrared cameras to find hidden leaks
  • Spray foam and caulk to seal every penetration
  • Attic hatch sealing with weatherstripping and insulation
  • Recessed light covers (IC-rated)
  • Duct sealing in attics and crawlspaces
