About Danisi Energy

Danisi Energy is a true family owned and operated full service HVAC and Fuel delivery company servicing the Suffolk County area on Long Island, Danisi Energy has been in business for over 60 years. We are the only true full service Heating, Ventilation, Air-Conditioning Company in the area. When we say Full Service we Mean Truly FULL SERVICE. Installation, Repair, Service, Maintenance, on ALL types of Heating, Ventilation, and Air Conditioning systems. We also Deliver Home Heating Oil, Kero (Kerosene) and Diesel for both your residential homes and commercial buildings.

When it comes to service, we don’t tell you to call the A/C “guy”, or the heating “guy”, or a plumber, or an electrician; we handle it ALL as full service company should be. We are also a family-owned and operated business. Even though it has been a challenge to compete with larger corporate companies, we have shined through because of our commitment to our valued customers. In the past, we have lost customers to our competitors only to have many return to us after being disappointed by the “Just a number” impersonal way in which they were handled by the larger corporations . A Danisi Energy customer knows we care about them and we’re here for them 24 hours a day  / 7 days a week. 

Do it once, Do it right, Do it with Danisi!

“We realize that it is families, like ours, that rely on Danisi Energy Company Inc. service. Therefore, our commitment is to every family and household who uses our services.”
-Will Sanchez, Director of Customer Relations

“Oil is Oil? True. Service is Service? Not True. Service is not service unless it is preceded by quality, reputation, integrity, and the willingness to stand behind your product.”
-Chris Ghosio, Managing Partner
