What Is The Life Expectancy Of An Oil Furnace?

Oil furnaces have a reputation for being old technology. Nevertheless, they are still in use today because they have several advantages over other heating systems.

Now, you’re probably wondering how many years of service an oil furnace can give you before you have to replace it.

Well, let’s look at some of the factors given by furnace services that determine the life expectancy of an oil furnace.

Type of oil furnace

Oil furnaces can be divided into two types: air-cooled and water-cooled. Air-cooled models use a fan to cool the heat exchanger; water-cooled models use water from a home’s water supply to cool the heat exchanger.

An air-cooled model typically lasts longer than a water-cooled model because it doesn’t have to deal with corrosion caused by condensation. However, the fan can wear out over time and cause a breakdown.

Quality of Installation

The quality of installation is a major factor in determining how long your oil furnace will last. An improperly installed furnace will not operate efficiently and may cause damage to other systems in your home. A properly installed system functions well and will provide reliable service and save you money on repairs.


Regular maintenance is essential to keep your heating system running properly and efficiently. This includes changing filters, cleaning coils, performing safety checks, inspecting vents, and making sure that all parts are working properly.

Don’t wait until something breaks; have a professional come out at least once every year for an inspection to make sure everything is working properly.

Age of furnace

Older furnaces tend to be less efficient than newer ones because new technology has made improvements over the years.

If you have an older unit with poor insulation or poor efficiency ratings, replacing it with a newer model could save you money on fuel costs over time.

The number of hours your furnace runs each year determines how much wear-and-tear it will experience over time. The more hours your furnace runs, the more likely it will be mechanical breakdowns in the system – which means higher repair costs and lower efficiency ratings over time.

Many new furnaces come with warranties that cover repairs made during the first few years after installation; these warranties are useful if you have trouble keeping up with regular maintenance appointments or if your usage history means that you need to repair or replace parts before their warranty period runs out.

Your local climate

A cold climate encourages better performance from furnaces because they don’t have to work as hard to keep your home warm in the winter months.

The same concept applies when it comes to the summer months; the hotter it gets outside, the harder it is for your furnace to cool down your household.

Many people who live in colder climates choose high-efficiency furnaces because they’re able to produce more heat per unit of fuel than conventional furnaces. However, there may not be enough need for this type of efficiency in warmer areas, and cheaper models may suffice just fine.

Condition of your home

According to heating service repair Long Island, a well-insulated home will keep your oil furnace running longer than a poorly insulated one because there’s less heat loss through walls and windows resulting from drafts around doors and windows.

Also, if you live in an older home with very little insulation, expect your unit to wear out quickly due to excessive heat loss through walls and windows during cold weather months when temperatures get extremely low.

Bottom Line

The fact is, no one can tell you exactly how long an oil furnace will last. That’s because there are too many factors that determine its longevity. However, you can gauge how long yours will last based on how you maintain it and the climate conditions.
