Home Energy Efficiency Consultants delivers complete HERS rating services designed for compliance, accuracy, and long-term performance.
Services include:
Each test is conducted methodically. Assumptions are verified. Results are checked before submission. Reports are produced in a format accepted by building officials and program administrators.
Massachusetts enforces some of the strictest residential energy codes in the country. For many projects in Wellesley, a verified HERS rating is required to close permits, pass inspections, and obtain a certificate of occupancy.
HERS ratings are commonly required for:
Projects that fail performance testing late in construction often face costly corrective work. Air sealing, duct repairs, or insulation fixes are far more expensive once drywall and finishes are installed. Early and accurate testing reduces that risk.
New construction offers the greatest opportunity for energy efficiency—and the greatest risk if testing is treated as an afterthought.
Home Energy Efficiency Consultants works with builders and project teams throughout the construction process, not just at the final inspection stage. This approach allows efficiency issues to be identified when corrections are still practical and affordable.
Common areas addressed during new construction:
Waiting until the end of the project to discover failures often leads to rushed fixes, compromised performance, or failed inspections. Early verification prevents those outcomes.
Air leakage is one of the largest contributors to poor energy performance. Uncontrolled air movement increases heating and cooling costs, reduces comfort, and introduces moisture-related risks.
Blower door testing measures how much air enters and exits the building envelope under controlled pressure. This data directly affects the HERS score and determines whether a home meets code requirements.
Improperly performed blower door tests produce unreliable results. Accurate testing requires proper setup, calibrated equipment, and experienced interpretation of the data.
Duct systems frequently lose a significant percentage of conditioned air before it reaches living spaces. Leaky ducts increase energy use, strain HVAC equipment, and compromise indoor comfort.
Duct leakage testing quantifies these losses and verifies whether the system meets allowable thresholds. This testing is especially critical in new construction and major renovations where system layout and sealing quality vary widely.
Correcting duct leakage early improves efficiency and prevents costly retrofits later.
Not all HERS raters operate with the same level of diligence. Incomplete inspections, rushed testing, or incorrect modelling lead to inaccurate scores and rejected documentation.
Common consequences include:
A low-cost rating that fails review is not a bargain. Accurate testing the first time protects schedules and budgets.
Homes in Wellesley present region-specific construction styles, age-related issues, and inspection expectations. Familiarity with local enforcement practices reduces surprises and keeps projects moving.
Home Energy Efficiency Consultants serves Wellesley and surrounding MetroWest communities with a clear understanding of Massachusetts energy codes and common regional failure points.
Local experience matters when compliance is on the line.
A qualified HERS rater provides more than a number. Professional service includes:
If results cannot be clearly explained, they are unlikely to be reliable.
A HERS rating is proof of performance, not marketing language. It confirms compliance, validates efficiency investments, and protects against costly surprises.
Home Energy Efficiency Consultants provides dependable HERS rating services for projects that require accuracy, accountability, and results that withstand inspection.
