What does oil heat service involve in Wilmington?
Oil systems need a yearly tune-up that replaces the nozzle and oil filter, cleans the combustion chamber, and tests efficiency. Common repairs include burner motors, ignition transformers, cad cell eyes, and fuel pumps. Oil furnaces cost about $4,000 to $10,000+ to replace, so converting to gas or a heat pump is often worth pricing.

- Burner locked out (red reset button)
- Smoke, soot, or oil odor

What is different about Wilmington properties?
Some older homes in Wilmington and parts of Greenville, Centreville, and Hockessin still heat with oil. Buried or basement oil tanks, chimney condition, and whether a gas main runs down the street shape the long-term decision.
Which brands and equipment are covered?
Oil burners are most often Beckett, Riello, or Carlin, fitted to boilers from Weil-McLain, Burnham, Peerless, and Utica, or to oil furnaces from Thermo Pride, Lennox, and others. See all brands and common issues.
