Quick answers
Common questions
Can I book or pay online?
No. Every appointment is set by phone and every job is invoiced after the work. Call 516-761-1525. We'll talk it through and set a time with you.
My oil burner stopped. Should I keep pressing reset?
Press it once at most. If the burner locks out again, stop: repeated resets can pump extra oil into the chamber and make the problem worse. Call us instead.
Do you work on both homes and businesses?
Yes. Residential and commercial heating and air conditioning across all of Long Island, Nassau and Suffolk Counties, on oil, gas and electric systems.
