Is the blower part of the furnace?

Is the blower part of the furnace?

The blower is one of the most appropriately named components in your furnace: its sole job is to blow hot air through the ducts and into your home.

What are the parts to a gas furnace?

The main parts of your furnace are the control system (thermostat and electrical controls), gas valve, burners, heat exchanger, blower, and duct and ventilation system. When your furnace creates heat, combustion gases are vented out of your home via a flue pipe.

Where is the blower motor on a gas furnace?

The blower fan motor is normally supported on rails near the bottom of the furnace. Since the motor power wires are connected to a control board that is often located in an upper compartment, two access panels may need to be removed.

What is the heat exchanger in a gas furnace?

Every furnace contains a heat exchanger. It’s an essential part of the heating process. Essentially, the exchanger is a thin metal shield standing between the combustion chamber and the blower, which distributes heated air from the furnace through air ducts into the living spaces of your home.

Can you run a furnace with a bad heat exchanger?

If it is your heat exchanger, you cannot run your furnace, even if it seems to be running fine. The gases will continue to seep into your home’s air. Many companies, upon finding a cracked heat exchanger, will shut your furnace down so you cannot run it.

What happens when heat exchanger fails?

A cracked heat exchanger poses a serious threat to the safety of your home. If there’s a crack in one of the cells of the heat exchanger, the gases being burned – carbon monoxide, sulfur dioxide, nitrous oxide – could leak into your home, causing illness or, in extreme cases, death.

Is it worth replacing a heat exchanger?

If your heat exchanger is cracked, your furnace is probably nearing the end of its life (18-20 years). If that’s the case, then it’s usually not worth the money to replace the heat exchanger. No matter who you ask, replacing a heat exchanger will be expensive. Heat pumps can heat and cool your home.

How do I know if my secondary heat exchanger is clogged?

1. The carbon monoxide readings in the exhaust will be elevated and sometimes off the charts.
2. The furnace will not run properly.
3. There may be water leaking from the lower portion of the furnace.
4. You may smell sulfur or a rotten eggs smell at the exhaust or near the furnace.

How do I know if my heat exchanger is blocked?

Symptoms Of Limescale Build-up Causing Heat Exchanger Faults

2. Boiler Lockouts. Your boiler is fitted with a NTC thermistor.
3. Leaks.
4. Noises.
5. Boiler Lockouts.
6. Dirty Water When Bleeding Radiators.

What happens when secondary heat exchanger fails?

If the heat exchanger fails, the furnace will “fail safe.” The worst thing that could happen is a “low heat” or a “no heat” condition. The enhanced warranty is a good thing. Carrier is standing behind their product and paying out labor for furnaces that are 10, 15, even 20 years-old.

Is it easy to replace heat exchanger?

You can’t repair or replace a heat exchanger because there’s too big a risk of carbon monoxide leaking into your home. It’s also cost-prohibitive. That’s why you need to replace the entire furnace. Nobody likes to hear that they need a new furnace, especially when the news seems to come out of nowhere.

How much does it cost to replace a furnace heat exchanger?

Replacing a furnace heat exchanger costs $1,500 on average with a typical range between $1,000 and $2,000. Most have a warranty of 10 to 20 years, which usually only covers the price of the exchanger, which typically ranges from $500 to $2,000. Labor alone runs an average of $500.

How long does furnace heat exchanger last?

In the past, heat exchangers were often built with heavy metals, such as cast iron. These exchangers can last as long as 30 or 40 years, much longer than the steel exchangers most manufacturers build today. Modern stainless or aluminized steel heat exchangers typically have a life span of 15 to 25 years.

When should I replace my heat exchanger?

Once done with the inspection, the technician explains that your furnace’s heat exchanger is broken or cracked and should probably be replaced. Have the contractor show you the exchanger. Anything broken or cracked that affects combustion will be easy to see.

How many heat exchangers are on a furnace?

Furnaces that are 70-80% efficient have one heat exchanger.

What causes a clogged heat exchanger?

The most common cause of an overheated heat exchanger is as simple as a dirty air filter. A clogged air filter restricts airflow through the furnace, overheating the heat exchanger, and eventually resulting in stress cracks. An over-sized furnace can also cause overheating and heat exchanger cracks.

Can a furnace heat exchanger be cleaned?

The heat exchanger on a furnace is another part that tends to have frequent dust and dirt buildup. If the heat exchanger needs cleaning, it’ll require special tools to remove and clean the heat exchanger. Therefore, you should always leave furnace cleaning to a professional heating contractor.
