Home owners tip-from Canadian Residential Inspection Services
"TIP OF THE MONTH"
"If you have a forced hot air system and you notice smoke / soot spillage on the ceiling, walls or drapes near any heating ducts or an unusual / combustion odour, it may be an indication of backdrafting or a compromised heat exchanger. Backdrafting is when the gases from combustion actually reverse themselves and enter the dwelling. A compromised heat exchanger is either cracked, rusted or burned through. Conditions may be found on any surface including the unit itself. This is potentially a sign of carbon monoxide entering your home and should be addressed immediately by consulting a heating expert.
Oil fired and gas fired furnaces that have been properly serviced and maintained, under normal conditions tend to have a life expectancy of approximately 20 years.
Don’t forget to reopen the dampers of your basement ducts if you closed them for the summer."
