Nassau County Generator Contractor

generatorOver the past couple of years, the Nassau County area has had more than its fair share of weather crises, and that’s why owning a home generator is so important. When devastating weather hits, people are often left without power for days, causing massive damage to homes and businesses. To help our customers be better prepared, T.F. O’Brien Cooling & Heating is pleased to offer our customers Honeywell automatic standby generators.

Honeywell automatic standby generators back up the circuits you choose during a power outage. They automatically start within seconds of detecting power loss, and run on the home’s existing natural gas or LP fuel supply. You’ll be able to choose a backup option from essential circuit, managed whole-house or complete whole-house coverage.
