How To Repair Furnace Heat Exchanger

What is a furnace estrus exchanger?

The estrus exchanger in your gas furnace is the part responsible for ensuring that harmful flue gases do not enter your home's air. Your furnace creates estrus using a combustion procedure. The oestrus exchanger works similar a blocker between the combustion

chamber and the blower. The blower is responsible for distributing the heated air from your furnace through the air ducts and into your home. There is also an inducer motor where the heat exchanger sends the flue gases so they are pushed through the flue pipe and out of a vent outside of your home. If the heat exchanger isn't working, the harmful gas and combustion fumes (potentially including carbon monoxide) will be pushed directly through the blower and out into your home's air, making it harmful to breathe.

How practice I know if my furnace rut exchanger is bad?

There are a couple obvious signs yous may notice with your furnace if your heat exchanger has failed.

• A change in the flame appearance in your furnace from a bluish colour to an orangish or yellow-like color. Blue is normal; other colors are not.
• Your furnace may beginning shutting down repeatedly on high limit. This is due to overheating.

There are other signs you have a cracked heat exchanger that may not exist and so obvious and these are the health issues that you may be experiencing. They include:

• Headaches
• Fatigue
• Nausea

There are many other issues that could be causing your symptoms, only these symptoms also match carbon monoxide poisoning which could signal that harmful gases are leaking into your abode'southward air.

What makes a heat exchanger fail?

Each time your furnace calls for heat, the metal that makes up the heat exchanger expands as it warms upwards.  One time the furnace turns off, then the metallic contracts back downward to its original size. This abiding process of expanding and contracting tin eventually lead to a crack over time. In some cases the oestrus exchanger can besides go damaged during installation. This is why it'southward always important to choose a professional person for your furnace replacement.

How to clean or repair a heat exchanger

It is non a standard procedure to make clean or repair a heat exchanger. At the end of the 24-hour interval it'due south either good or bad. How tin you lot be sure that your heat exchanger has gone bad? An HVAC service technician may inspect a heat exchanger with a combustion analyzer and/or a camera. The combustion analyzer will check inside your furnace to measure the corporeality of CO in your air. Annihilation over 100ppm (parts per meg) within of the flue pipe indicates a crack in the heat exchanger and the furnace must be shut downwards. This ways that CO could already be present in your home's air or will exist if the furnace continues to operate.  The heat exchanger at that bespeak would need completely replaced as it is not possible to repair it. Ask your heating service technician to bear witness you the combustion analyzer readings and/or the cracks in your heat exchanger. Sometimes visually seeing the damage to the heat exchanger can be hard without taking the furnace apart depending on where it is located in your brand and model of furnace.

Replacing a heat exchanger

Can you supercede but the heat exchanger instead of the unabridged furnace? The answer is yes! Depending on the historic period of the unit of measurement, it could really make more financial sense to just supercede the oestrus exchanger. If the furnace is more than than 10 years old, then we would recommend furnace replacement instead since over ten years of age other parts of the furnace may start to close downward presently also.

Cost

The cost to replace a failed oestrus exchanger is typically somewhere between $900-$ii,500 depending upon the size of the furnace and the cost of the particular heat exchanger that the furnace uses. Each brand of furnace may use a slightly unlike rut exchanger. Dissimilar manufacturers can also build their furnaces slightly differently, making the heat exchanger a more labor-intensive process to take out and replace, causing an increment in the labor toll of replacing the role.

Can't I just expect until my carbon monoxide detector tells me I have a trouble?

Don't rely on your CO detector alone because that ways a large amount of CO is now present inside your abode and has been an ongoing problem. During a furnace tune up and inspection, your HVAC service technician can check for CO levels inside your furnace and hopefully catch an upshot before the CO has actually began leaking out in large quantities into your home.
