If we’ve learned anything here in Suffolk over the last few years, it’s that the weather can be unpredictable – and disastrous. Owning a home generator is more important than ever, because severe weather can leave people without power for days, which can cause damage to equipment and appliances. To better serve our customers, T.F. O’Brien is now a full service generator contractor, offering top-quality Honeywell standby generators.
Automatic standby generators from Honeywell provide back up to the circuits you choose during a power outage. They start automatically within seconds of detecting power loss, and run on your 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.
