This 83%, variable-speed furnace offers good comfort and very high quality. As Lennox’s best oil furnace, it should last up to 20 years and possibly longer with regular cleaning. This is a quiet furnace too, and it uses the highly-rated Beckett Flame Retention burner. Carrier and other leading brands of oil furnaces also choose Beckett burners for their top models.

How to Get the Best Performance from the Lennox SLO183V Furnace

Oil furnaces need to be properly installed to deliver the most efficient and durable operation. DIY installation is not recommended. Plus, when running oil line and venting dangerous combustion gases, having a pro on the job gives peace of mind. Consider hiring a qualified contractor with certification from Lennox for oil furnace installs. It makes sense to get at least 3 written estimates, and then choose the contractor with the right blend of experience and price. When you do, the Lennox SLO183 oil furnace should meet or exceed your expectations.
