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.
