How to Keep Your Furnace Running Safely and Efficiently

By Karin Mangan HIPhome Columnist December 31, 1969

An inefficient furnace may not only cost you money, but thanks to the larger amounts of fuel required to heat your home; it could also cost your life.

Old or Inefficient Furnaces can Emit Deadly Levels of Carbon Monoxide

Carbon monoxide is a natural result of incomplete combustion. It is emitted in small amounts by most furnaces and normally goes out through the furnace vents. A gas-burning furnace that is faulty, dirty, or burning inefficiently can produce deadly amounts of carbon monoxide. The colorless, odorless gas can be detected by installing a carbon monoxide detector and alarm. However, without a detector, you may only be aware of the carbon monoxide as a result of feeling unwell, or you may not be aware of it at all--breathing in high levels of carbon monoxide can result in death.

The Importance of an Annual Furnace Check

You can do some cleaning and maintenance yourself, with reference to the manufacturer's manual, but an annual furnace check by a qualified heating and plumbing professional is recommended by the U.S Centers for Disease Control and Prevention.

Replace You Filter to Keep Your Furnace Running Efficiently

One of the most important ways to keep your furnace running safely and efficiently is to replace or clean your furnace filter or filters at least three or four times a year. It is a good idea to check the filter monthly during periods of high usage. Filters that are clogged reduce the efficiency of the furnace and can cause parts to wear out more quickly. A clean filter also minimizes the amount of dust and allergens that are circulated around your home.
