The importance of regular furnace tune-up cannot be emphasized enough. Keeping the furnace properly tuned not just ensures efficient operation, it also prevents build up of dangerous gases inside the house. If the furnace is not kept properly tuned, dangerous carbon monoxide gas can leak inside the house.
What is carbon monoxide?
Carbon monoxide is a colorless, odorless gas. Effectively invisible, it’s lethal in sufficient doses.
Carbon monoxide poisoning can result in a number of uncomfortable health symptoms including weakness, dizziness, upset stomach, chest pain, vomiting, and in some cases even death.
That’s why it is essential that you have the system properly tuned by a professional and experienced technician.
How do carbon monoxide leaks occur?
Carbon monoxide leak can occur inside the house in case of a cracked heat exchanger. The heat exchanger is an important component of the furnace that allows transfer of heat from one medium to another.
The heat exchanger inside the furnace consists of metal sheet that is heated once the burner is lit up. Cold air passes outside of the heat exchanger and becomes warm. This warm air is circulated inside the room through the ductwork.
The natural gas that burns inside the furnace to generate the heat produces by-products including carbon monoxide that is kept by the heat exchanger. In case a crack develops in the heat exchanger, the carbon monoxide can leak and circulate through the ducts inside the rooms thereby posing a major health risk for the family.
You can’t normally see or smell carbon monoxide. Also, the crack in the furnace is not easily visible. The only way to detect the leak would be to use a carbon monoxide detector.
How do furnaces develop cracks?
There are many reasons that the heat exchanger can develop a crack. They develop crack as a result of normal wear and tear. Normally, cracks tend to occur about 15 years of use. But if the system is not serviced regularly, the cracks can occur even earlier.
Another cause for the cracks to appear in the heat exchanger is that the furnace is too big for the home. This results in shorter cycling that causes the exchanger to heat up and cool down rather quickly. Eventually, a crack will develop through which the carbon monoxide can leak inside the house.
Also, clogged furnace filter can also cause cracks to appear in the heat exchanger. Dirty or dusty air filter will lead to overheating problem. Overtime this can result in cracks inside the exchanger.
Avoiding carbon monoxide problems
The best way to avoid leakage is to have the furnace serviced regularly by an experienced technician. Consider signing an annual maintenance contract with the furnace repair company to ensure that your system remains in good shape.
