Not sure? Most Hampton Roads homes built before 2000 have R-6 or less.
Hampton Roads Dominion Energy summer average: ~$260/mo. Summer cooling is the biggest driver of high bills.
Why Hampton Roads Homes Lose So Much Energy
Hampton Roads sits in DOE Climate Zone 4A — a hot, humid region where your HVAC system works overtime all summer. Inadequate attic and crawl space insulation lets radiant heat blast through your ceiling and floor, forcing your AC to run constantly and driving up your Dominion Energy bill every month from June through September.
HVAC Drives Seasonal Costs
Heating and cooling are often among the largest household energy costs. Better insulation can reduce that demand, especially during Hampton Roads summers.
DOE Recommends R-49 Attic / R-19 Crawl
Most Hampton Roads homes have R-6 to R-19 in the attic. Upgrading to Climate Zone 4A standards may reduce HVAC costs; actual savings vary by home, HVAC system, usage, and energy rates.
Typical Planning Range: 3–7 Years
Some insulation projects may recoup their cost over several years. Actual payback depends on the home, existing insulation, HVAC use, project scope, and energy rates.
