Energy Efficiency Assessment Rochester MN Homes

Rochester homeowners spend $2,000-4,000 annually on heating and cooling — significantly above the national average due to our extreme climate. An energy efficiency assessment identifies where your home loses energy and which improvements deliver the best return on investment.

Thermal Envelope Assessment

Your home's thermal envelope — walls, ceiling, floor, windows, and doors — determines how well it retains conditioned air. Using thermal imaging, we identify insulation gaps, air leakage paths, and thermal bridging that waste energy. Rochester homes built before modern energy codes often have significant opportunities for improvement.

Insulation Evaluation

We measure insulation levels in accessible areas and compare them to current Minnesota standards: R-49 for attics, R-21 for walls, R-10 for foundations. Many older Rochester homes have less than half the recommended insulation. Upgrading attic insulation from R-19 to R-49 typically costs $1,500-3,000 and reduces heating costs by 15-25% — one of the highest-ROI home improvements available.

Window and Door Efficiency

Windows are typically responsible for 25-30% of a home's heat loss. We evaluate window type (single, double, triple pane), seal condition, weatherstripping effectiveness, and storm window presence. For older Rochester homes with original single-pane windows, storm windows or replacement windows can dramatically reduce energy costs and improve comfort.

HVAC System Efficiency

We evaluate your heating and cooling system efficiency, ductwork condition and sealing, thermostat programming, and zoning effectiveness. A 20-year-old 80% efficiency furnace replaced with a 96% unit saves approximately $400-600 per year in a typical Rochester home, paying for itself within 6-8 years.
