Routine heating maintenance is one of the most important ways to protect the investment you’ve made in your home heating system – but what actually happens during annual heating maintenance visit to make it so important?
Mostly, your technician is looking for ways to make your heating oil-fired system perform better or more safely, doing everything from checking exhaust draft composition and temperature to measuring combustion efficiency. But he’s also looking for common problems that occur with most heating equipment over the course of its lifetime.
Here are some of the issues typically uncovered during your heating system maintenance visit, and what the likely cause is for each:
| Issue | Cause |
| Clogged air filters | Soot/dust |
| Dirty nozzles | Soot/dust |
| Excessive wear and tear | Age |
| Electrical ignition | Faulty ignition Thermocouple problems Clogs in the device |
| Frequent cycling | Clogged filters Thermostat settings Poor airflow |
| Faulty Thermostat | Electrical wiring or age |
| Noisy Furnace | Mechanical issues Clogged burner |
| Blower won’t shut off | Broken limit switch |
| Not enough heat from furnace | Clogged filter Wrong size for home setting |
