George Hafner Oil Burner Service

George Hafner Oil Burner Service maintains a 4.4-star rating across 98 customer reviews as a heating-focused contractor serving Nassau County, New York. Based in Levittown at 86 Harvest Lane, the company specializes exclusively in oil-fired burners and boilers, along with hot water heater systems. The business operates around the clock year-round, offering 24-hour emergency service with a dedicated late-night number at (516) 754-8560. All technicians are licensed and insured for residential oil-fired equipment work throughout Nassau County.

What distinguishes this contractor is their narrow focus on heating and hot water systems rather than broader HVAC offerings. The company provides free estimates on boiler and water heater installations, yearly maintenance servicing, and burner repairs. They advertise military and senior discounts plus a 10% first-call incentive for new customers. Their 24-hour availability during winter months (8 AM to 1 AM) reflects the urgency of heating emergencies in the Long Island climate.

Customer reviews reveal mixed but informative experiences. Reviewer John Pfeifer praised technician Kevin for completing a boiler installation with excellence and following up the next day to verify peak efficiency. Michael Squires described a same-day Sunday emergency response when an oil-fired water heater cracked, with the crew stopping the leak that night and installing a replacement by the following afternoon. However, negative reviews from Frank Collora and Keith Macdonald cited service failures including no-shows after promised arrival windows and dismissive responses to post-service complaints.
