When to Schedule an Oil Burner Tune-Up

From the Alcus family · Alcus Fuel Oil & Sons, Amityville · Updated October 30, 2026

An oil burner should be cleaned and tuned once a year. The best time is late spring to early fall — but if your system hasn't been serviced in over a year, the best time is before the next cold snap.

Why it matters

• Fewer no-heat calls. A clogged nozzle or filter is one of the most common reasons a burner quits in January.
• Less oil burned. Soot on the heat exchanger acts like insulation, so more heat goes up the chimney.
• Safety. A technician checks for leaks, draft problems and signs of trouble before they're dangerous.

What a tune-up usually includes

• Replacing the nozzle and oil filter(s)
• Cleaning the burner and the combustion chamber / heat exchanger
• Checking the flame, draft and combustion and adjusting the burner
• Checking controls, safety devices and visible oil lines
• A look at the tank for rust, wet spots or weeping seams

Exact steps depend on your equipment; we'll tell you what we did.

Signs you need service now, not next summer

• Soot around the burner or smoke from the chimney
• Oil smell, rumbling or banging at start-up
• The reset button trips
• Your oil use jumped without a cold winter to explain it

Save with a service contract

A service contract includes a yearly tune-up and priority service when it's coldest. Equipment 20+ years old and needing repairs every winter? Ask about a free boiler replacement or furnace replacement estimate.
