Many homes in southern Maine still heat with oil. That isn't a reason to pass on a house, but the heating system is one of the biggest costs you'll take on, so it's worth understanding before you buy.
The furnace or boiler
Ask how old the equipment is and when it was last serviced. Oil systems should be cleaned and tuned every year, and the service company usually leaves a tag on the unit with the date. A missing tag or a long gap between services is worth asking about.
The oil tank
Find the tank and look at it. Note whether it is in the basement or outside, and look for rust, damp spots, or stains underneath. Many tanks have a manufacture date stamped on them. An old tank isn't automatically a problem, but replacing one is a real expense, and some insurance companies ask about tank age.
The chimney
Oil equipment vents through the chimney, so the chimney needs to be lined and in good condition. Your home inspector can tell you what they see, and a chimney professional can look further if needed.
Fuel usage
Ask the seller how much oil the home used last year. The delivery company can often provide a record. It's the most honest estimate of what heating will cost you.
