Jones Energy Solutions in Carlsbad is a CalCERTS-certified HERS Rater operating from Faraday Avenue near the El Camino Real corridor, conducting Title 24 energy-compliance testing for new construction, HVAC alterations, and additions throughout San Diego County. Duct-leakage and blower-door tests verify envelope tightness for insulation contractors such as All Type Insulation Services, whose batt and blown-in installations must pass Quality Insulation Installation verification before the HERS rater signs the CF-3R compliance certificate. The firm holds BPI Building Analyst and BPI Multifamily Building Analyst certifications, qualifying it for whole-house HERS II energy ratings on both single-family and multifamily properties across SDG&E, SCE, and SoCalGas utility territories. Testing protocols include refrigerant-charge verification, thermostatic-expansion-valve inspection, fan-watt-draw measurement, airflow-rate confirmation, and infrared thermal scanning — each documented on California Energy Commission compliance forms for builder permit sign-off with electrical verifiers such as Green Earth Electric. LEED-certification projects require additional HERS verification of solar-photovoltaic system output and building-envelope performance, with the rater producing third-party documentation that confirms the as-built home meets or exceeds the modeled Title 24 energy budget.
