Gas furnace parts: What are they and how do they work?

Many people here in southern Louisiana rely on a gas furnace for their winter heating. Yet, there are many gas furnace parts that go into making that comfort possible.

In this blog post, we’ll explain the major parts of your furnace, from your heat exchanger to your thermostat.

What gas furnace parts are there?

In order to better understand how gas furnaces work, let’s go over the main components of the heating system.

This furnace is made up of many gas furnace parts, including a heat exchanger.

1. Heat exchanger

The core of your gas furnace is the heat exchanger. As the name itself suggests, the heat exchanger generates heat through an exchange process, adding heat to the air, thereby warming your home.

A heat exchanger consists of a set of coils or tubes that are looped inside the exchanger. A blower motor inside the gas furnace then blows the heated air from the heat exchanger into the ductwork. From there, it’s circulated throughout the house.

As one of the essential gas furnace parts, a cracked heat exchanger is bad news. Not only can it negatively impact your home’s heating, but it can also pose a danger in the form of carbon monoxide release.

2. Gas burner

The gas burner heats up the air in the heat exchanger. When you turn on the gas furnace, a small flame known as the pilot flame burns at a low temperature in the gas burner. The flame heats up the air inside the heat exchanger, which is then distributed inside your home.

3. Gas manifold

Another one of the most important gas furnace parts is the gas manifold, which connects burners with the gas valve. Brass fittings called spuds connect the burners to the manifold. The amount of gas that is transported to the gas burners depends on the size of the hole drilled in the manifold.

Comparatively, this part requires little maintenance and care as compared to other components of the gas furnace. Still, when you schedule a furnace tune-up with us, we’ll take a look to make sure your gas manifold is still operating properly.

4. Thermostat

Thermostats control the temperature in your home. You can use them to adjust the temperature according to your comfort level. When you turn up the thermostat, the flame of the gas burner gets larger (via the gas burner), increasing the temperature. On the other hand, when you turn down the thermostat, the flame shrinks, lowering the temperature.

You should place the thermostat in the location that will allow the gas furnace to heat the home evenly. The best place to place the thermostat in the middle of the house. Make sure that you place the thermostat away from the windows and walls to prevent uneven heating.

Now’s a good time for a backup generator inspection

Your home’s backup generator is a lot like car insurance: you hope you don’t ever have to use it, but chances are that you will need it one day, and you need it to be ready to help you. Make sure your generator is ready to go with a backup generator inspection from the pros at Bob’s Heating & Air Conditioning.

It’s important that electrical generators are properly maintained to ensure that they work without a problem when they’re needed the most. Here in Houma, Berwick, Morgan City, and other parts of southern Louisiana, it’s a good idea to have your generator ready for future storms and hurricanes.

A backup generator inspection can make sure your gas generator continues to run right when you need it most.

To schedule a backup generator inspection from our team, give us a call at (985) 855-5775 or schedule a checkup with us.

Three reasons to schedule a backup generator inspection

1. Prevent fuel leaks

Older generators are susceptible to leaks. These leaks can come from a fuel line, hose, or storage pan. They may be gas or oil, depending on the type of the generator you have at your home.

The coolant that prevents the engine from overheating may also leak. Scheduling a routine inspection of the unit is the best way to address the problem. The licensed and experienced technicians at Bob’s will thoroughly inspect your unit to look for leaks and perform necessary repairs.

2. Increase the lifespan of the generator

Another benefit of getting your generator inspected is that it will be likelier to live a longer life. Most generators have an operating lifespan of 20 to 30 years. The fact is that the generators represent a major purchase for most people.

In order to ensure optimum lifespan of the generator, it’s essential that you get it inspected by a professional technician at Bob’s Heating and AC.

3. Have peace of mind for whatever’s next

The reality is that a power outage can occur anytime. Hurricanes, snow, high winds, and other natural elements can knock out the power supply from the utility companies. A home generator kicks on as soon as that happens to provide continuous power to your home.

There is nothing more frustrating than having to shiver during the cold winter months or sweat out during the summer months due to a power outage. And who knows how long that outage will last!

With a properly maintained backup generator, you will have the peace of mind in knowing that you don’t have to face any inconvenience during a disruption in power supply. You and your family will be safer and won’t experience any problems during the power outage.

There will be no spoilage of food and the electrical appliances can be used to cook meals, clean clothes, and above all remain comfortable despite frigid cold or scorching hot temperature outside.

Here are 5 signs you need a new furnace in your home

“Should I replace or repair my furnace?” This is a common question that comes into the minds of homeowners whenever their furnace breaks down. How you do you know what the signs are that you need a new furnace?

While replacing the furnace is an expensive option, but sometimes you will save more in the long run when you replace the old furnace with a new one. This is mainly because the new furnace will require fewer repairs and operate with increased energy efficiency.

So, how can you know whether you should replace or repair the home furnace? Here are 5 signs that show that you need to install a new furnace instead of repairing it if you want to save money in the long run.

1. Energy bills have increased

As the furnace gets older, it draws more power to generate the heat resulting in increased energy bills. If you are paying significantly more in energy bills as compared to the previous year but the rates and energy consumption have remained somewhat the same, you should consider installing a new furnace. Newer models perform at greater energy efficiency levels as compared to older models. Depending on the type of the new furnace, you may be able to save $50 to $100 in energy bills every year.

2. The heat exchanger is damaged

The heat exchanger is an important component of the furnace that helps in generating warm air. If cracks develop inside the exchanger, the furnace will not be able to heat up the air. Also, there is a risk that carbon monoxide may leak when the exchanger gets damaged posing a serious health hazard to the household. Replacing the heat exchanger could cost up to $2000. At that price, you can easily buy a modern energy efficient furnace for your home.

3. There’s a fault in the circuit board

The circuit board is another important component of the furnace. It controls a variety of complex processes and monitors operation of the furnace. A problem with the circuit board will make the furnace fan blower to run improperly creating noise and drawing more energy. Replacing the damaged circuit board can cost you around $500 to $1,000. You might be better off buying a new furnace instead of replacing the circuit board as it might save you more over time.

4. You have a faulty furnace motor

The warm air generated by the furnace is pushed throughout the home by the motor. If the motor gets damaged, the heated air won’t move throughout the home. Upgrading the furnace is a better option in such a situation as it will save you more in the long run as compared to replacing the motor.

5. There are strange sounds coming from the furnace

If you hear rattling, clanging, or another strange sound from the furnace, it could point to a major issue with the furnace. Of course, it may also mean that something is loose inside the furnace.

You should let a professional technician from Bob’s diagnose the system to find out the cause of the noise. If there is something seriously wrong with the furnace, it’s better that you install a new energy efficient furnace instead of repairing it.
