About Maselli Contracting & HVAC LLC
Maselli Contracting & HVAC LLC holds a 4.9-star rating across 387 reviews, reflecting years of dedicated service throughout Westchester County. Based in Hawthorne with headquarters in White Plains, the company operates as a full-service residential and commercial HVAC and plumbing contractor. Their service area covers more than a dozen communities including Mamaroneck, Scarsdale, Dobbs Ferry, and Eastchester, delivering installation, maintenance, and emergency repairs to homeowners who need systems functioning reliably year-round.
What distinguishes Maselli is their commitment to same-day emergency response combined with transparent pricing and respectful in-home service. The company maintains 24/7 availability for heating and cooling emergencies, understanding that a failed furnace during a Hudson Valley winter or an AC breakdown during a heat wave cannot wait for Monday morning. Their technicians undergo ongoing training to service all major boiler, furnace, heat pump, and central air systems, and they offer customized preventative maintenance contracts designed to extend equipment lifespan and prevent costly breakdowns.
Customer reviews consistently highlight specific technicians who went above and beyond. Stevens arrived at a home within four hours during a blizzard aftermath to restore heat for a household with an elderly, bed-bound resident. Nancy Sinnott's heating zone problem, unsolved by multiple HVAC companies over several years, was finally resolved by a Maselli technician who took the time to diagnose the root cause. Reviewers repeatedly praise the lack of upselling pressure and the technicians' respect for homeowners' time and property.
What Customers Say
Every customer review rates 5 stars, with 4 of 6 reviewers specifically naming the technician who served them and noting same-day or rapid response times. Multiple reviewers contrast Maselli favorably against other area contractors who failed to diagnose problems or communicated poorly.
