What is a Heat Exchanger?

A heat exchanger is a series of metal tubes inside the air stream of a furnace’s fan. This is the first area of the furnace that combustion gasses enter. These gasses are then relocated to the heat exchanger’s walls where they become warm and are circulated throughout your home.

How Does a Heat Exchanger Affect You?

A heat exchanger is an essential component of your furnace and should be maintained to ensure the comfort and safety of your home. Without it, the air in the furnace would be unable to heat and cold air would blow through your home instead.

The combustion gasses transferred in the heat exchanger are most often fossil fuels, which can be extremely harmful to you and your family’s health. As the gasses and flames follow the heat exchanger’s metal tubing, they pass through a flue pipe or chimney. If the heat exchanger is cracked, these harmful gasses—like carbon monoxide—can escape and disperse throughout the home.

These kinds of fumes should be eradicated immediately for your safety. If a certified HVAC professional like our Bardi technicians find a crack in the heat exchanger, they will immediately shut the furnace down to avoid any carbon monoxide poisoning. This is Bardi’s policy and is performed for the safety of homeowners.

Signs of a Cracked Heat Exchanger

There are some ways to potentially detect cracks in the heat exchanger, but ultimately furnace maintenance and regular check-ups are the best ways to ensure your furnace is in proper shape.

• Long delay between adjusting the thermostat and the furnace turning on
• Burning smell when the furnace turns on

What Are Your Options?

If you find or suspect that your heat exchanger is cracked, you should immediately contact a Bardi professional for assistance. They will be able to fully inform you of your options.

One of your options is to replace the carbon monoxide barrier in your furnace’s heat exchanger. While this will solve your heat exchanger problem, it is not often the most cost effective solution.

Most technicians will encourage you to upgrade your unit for the best and most cost effective results. Several of Bardi’s heating units have carbon monoxide barriers built-in with lifetime warranties included. These units ensure that you are protected should your heat exchanger experience a crack in its infrastructure.

It is extremely important for homeowners to contact Bardi for preventative maintenance inspections each year. This will guarantee that you and your family remain safe and that your home stays warm and free of carbon monoxide throughout the colder months.
