HIC license required for general contractors managing the project — Consumer Protection Bureau: 914-377-3000. New York does not require HERS third-party testing (California-specific). Con Edison serves Yonkers for both electricity and natural gas (1-800-752-6633 / coned.com).
Yonkers' CZ5A climate (NYC metro, design temperature approximately 10°F) makes heat pump installations highly cost-effective. Cold-climate heat pumps (NEEP ccASHP, -13°F rated) are recommended for effective performance at Yonkers winter temperatures. Con Edison rebate programmes and NY State NYSERDA incentives both apply to qualifying heat pump installations in Yonkers — check coned.com and nyserda.ny.gov for current programmes before finalising equipment selection.
Many Yonkers homes use steam or hot-water radiator systems heated by gas boilers. Converting to heat pump requires either replacing the distribution system or using high-temperature heat pumps designed for radiator systems. Specify contractors with hydronic-to-heat-pump conversion experience for radiator homes.
