Carbon Monoxide Is an Unwelcome Holiday Houseguest

Carbon monoxide (CO) gas poses a particular threat this time of year. Most carbon monoxide poisoning incidents happen in the winter, as people turn on the furnace or use the fireplace or when snow blocks vents and chimneys. The December 3 issue of First For Women magazine cites sources that indicate up to 11 million people are exposed to low levels of CO every day. Since carbon monoxide is a colorless, odorless, tasteless gas, leaks usually go undetected. Early symptoms of CO poisoning – headache, nausea, dizziness, and confusion – are often overlooked and may only be discovered after a collapse. While low levels of CO gas are not usually fatal, they may leave people with flu-like symptoms. Experts warn that there is no safe level of exposure to CO.

The Centers for Disease Control (CDC) recommends having your heating system, water heater, and any other gas-, oil-, or coal-burning appliances serviced by a qualified technician every year. “Poorly maintained devices, like boilers and furnaces, can be significant sources of CO gas, but even a brand-new furnace can pose a hazard if improperly installed,” said Dave Moody, Director of Field Marketing for Service Experts Heating & Air Conditioning. “An annual furnace tune-up will help identify and correct potential problems, as well as saving homeowners extra money on energy bills,” he added.

Homeowners with fireplaces should also have their chimney checked professionally once a year. If the chimney flue is blocked or damaged, it may prevent dangerous gases from being properly vented out of the home. For early detection, Service Experts Heating & Air Conditioning also recommends that homeowners install a battery-operated or battery back-up CO detector on each floor of their home and check or replace the battery every six to 12 months.

For homeowners who turn to gasoline- or diesel-powered generators during power outages caused by winter storms, Service Experts cautions that these machines also emit CO. (In fact, nine deaths were attributed to CO poisoning in the immediate aftermath of Superstorm Sandy on the East Coast.) These generators must never be used indoors, which includes the garage. A generator should be placed with 3'–4' of clear space on all sides and should not be close to your home's doors, windows, or vents.

Because winter months are traditionally the slower season for heating and air conditioning contractors, they may offer significant seasonal savings and specials to homeowners who want to replace aging heating equipment. Through February 28, 2013, Service Experts branches across North America are offering deals that include a free furnace or furnace upgrade with qualified purchases.
