Outdated Oil Furnace Maintenance in West Allis

Oil furnace systems are common in the older homes throughout Milwaukee County. While oil furnaces are more expensive to run than gas furnaces, they tend to last longer than gas appliances. Oil furnaces provide more heat per BTU than other heating sources, but they must be regularly serviced due to dirt and soot buildup. The oil filters must be changed frequently.

Warming Home with Furnace SystemWhich Furnace is Best in Wisconsin: Oil or Gas?

The right furnace for your home or business will depend on many factors, like total square footage and building insulation. Gas and oil units each have their own benefits and drawbacks. Natural gas tends to be cheaper than oil, though furnaces run on gas are initially more expensive than their oil counterparts. Both types are capable of lasting for decades with the right maintenance. Our technicians will help you select the right type of furnace for your property.

Note: Natural gas furnaces have an additional risk compared to oil units. Gas-burning furnaces can create carbon monoxide. If the unit is not functioning properly, it could create a harmful, potentially fatal, carbon monoxide leak. We minimize the risk of harm to you and your family by checking over every component of your gas furnace. 

If you have an older oil or gas furnace it is best to get it replaced now to maximize efficiency in the future. In addition to installing, maintaining, and repairing gas/oil furnaces, Donovan & Jorgenson works on boiler furnaces too.
