Heating Oil Basics → Annual Tune-Up
An oil furnace or boiler is one of the hardest-working appliances in your house, and the cheapest insurance against a no-heat night is an annual tune-up. A clean, properly adjusted system burns less fuel, lasts longer, and is far less likely to quit on the coldest day of the year. Here's what a tune-up actually includes and when to book one.
A proper annual service from a qualified oil technician typically covers:
Book your tune-up in late summer or early fall, before the heating season starts. You'll get earlier appointments, avoid the winter rush (when techs are slammed with emergency calls), and head into cold weather with a system you trust. Many suppliers include an annual tune-up in a service plan or discount it for delivery customers — ask.
A standalone annual tune-up typically runs $150–$300 depending on your area and system. If you're on a service or budget plan with your oil dealer, it's often bundled in. Compared to a single emergency no-heat call — especially after hours — the tune-up usually pays for itself.
Plan around your heating season with HomeHeat
Track usage, predict run-out dates, and stay ahead of refills and service — free, no hardware required.
Once a year, ideally before the heating season begins. Oil systems need annual service more than gas systems because the fuel leaves deposits that build up on the nozzle, filter, and heat exchanger.
Replacing the oil filter and nozzle, cleaning the electrodes and combustion chamber, running a combustion analysis, checking safety controls, and inspecting the flue. The combustion analysis — measuring and adjusting the burn — is the part that requires a professional.
Late summer or early fall, before cold weather. You'll get easier scheduling and avoid the winter emergency rush, and your system will be ready for the season.
Typically $150–$300 for a standalone visit, or bundled into a service/budget plan with your oil dealer. It's generally cheaper than a single after-hours emergency repair.
