Generators on Long Island, NY

generatorOver the past couple of years, the Long Island 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 is pleased to offer our customers automatic standby generators.

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.

The New A/C is Wonderful

Excellent service from beginning to end. The new A/C is wonderful.

Installation was First Rate and Professional

Tom did a great job. Got 5 other estimates: one did not respond, another sent a proposal via email which I could either accept or decline with no questions entertained. We had a special situation and only Tom was able to understand it and figure out a way to do the job. We're very happy with our new Daikin unit-operates exactly like Tom said it would. The installation was first rate and professional as well. Would certainly recommend.
