Long Island Generator Contractor

generatorLong Island has suffered through a number of weather crises over the past few years, 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 for any emergency, T.F. O’Brien Cooling & Heating is now a full-service generator contractor offering top-quality 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.

"Exceeded Expectations Throughout"


"The installation of a new central a/c unit exceeded expectations throughout the entire process...a true professional team throughout.

Thorough explanation of available options, responsive scheduling, seamless installation in one day by a diligent crew that took great care to be neat and clean, including the complete removal of the old system.

Would highly recommend the T. F. O’Brien team for installation of a new A/C system."
