Danisi Energy CO

We are a family-owned and operated HVAC and fuel-delivery provider based in Medford, New York. For more than 60 years, we have served homes and commercial buildings throughout Suffolk County on Long Island. We provide full-service support for heating, ventilation, air-conditioning, fuel, plumbing, and electrical needs.

Our HVAC services include installation, repair, routine service, and maintenance for all types of heating, ventilation, and air-conditioning systems. Because we handle a broad range of related needs, our customers do not have to search for a separate air-conditioning technician, heating technician, plumber, or electrician each time a different issue arises. We handle these needs as part of our full-service approach.

We also deliver home heating oil, kerosene, and diesel for residential and commercial properties. Our regular hours are Monday through Friday from 7:00 a.m. to 6:00 p.m. and Saturday from 8:00 a.m. to 1:00 p.m. Emergency service is available 24 hours a day, seven days a week, 365 days a year. Customers can find us at 3205 Route 112, Medford, NY 11763, or call us at (631) 732-6666. For the East End, our number is (631) 283-0400. As a family-run operation, we care about the people we serve and remain available when they need our help.
