Gates Mills Heating Question: What Are Flue Gas Spill Switches?

Monday, February 6th, 2012

While some components of a heating system make sense to the average Gates Mills homeowner – think blower fan, thermostat and air ducts – others are more esoteric and prone to bouts of head scratching.

So, you may find yourself asking “what the heck is a flue gas spill switch?”

As you know, gas heating appliances produce heat by means of combustion. The gas line feeds gas into the appliance, the gas is ignited, and the burning gas produces heat. It’s a simple concept that goes all the way back to our caveman ancestors building fires to keep warm, and it is the same process in gas furnaces, boilers and water heaters.

In addition to producing the cozy heat we love in the winter time, this combustion process also releases gases. Known collectively as “flue gases,” some of these – carbon monoxide being the most notorious – can be very toxic. This why we have flues or chimneys in our homes– to give these gases a means of egress.

A flue gas spill switch is designed to shut down the furnace if these gases start seeping out. It is made up of a sensor or series of sensors that detect heat outside the flue, not unlike the flame sensor in your furnace. If flue gases start to escape and pass by the sensor, the sensor heats up and signals the furnace to shut down. This cuts off the power and gas, so that no more flue gases can leak into the home and create a health concern.

If your furnace has been abruptly shutting down, it could be your flue gas spill switch trying to tell you that you have a leaky or cracked flue. If this is the case, you want call Apple Heating and Cooling to have it repaired right away. The constant off and on is not good for the furnace, and more importantly, those flue gases can be exceptionally hazardous to your family’s health.

Austinburg Heating Repair Guide: Furnace Air Temperature

Friday, January 13th, 2012

When your furnace turns on every day and warms your Austinburg home, just how hot is the air being blown through your vents? It’s a common question and while it varies depending on the type of furnace you have and the length of your ductwork, normally, the air is about the same temperature in most homes.

The Heating Process

When you turn on your furnace, it ignites fuel (gas or oil) or heats elements (electricity). A blower fan blows air through the heat exchanger and then into ductwork that distributes the heated air to vents around your home. When the combustion occurs and air is first heated, the temperature is between 140 degrees F and 170 degrees F.

This is extremely warm and could be dangerous to anyone if they got too close to it or it was blown directly into your home. However, as the heated air is distributed into your home it starts to cool. In some cases, it loses a significant amount of its energy in the ductwork.

This is intended, of course, because the temperature would be much too high if it was distributed directly to your rooms. That’s why high velocity ductwork often requires regulation to avoid overheating of the air. Cooling like this is normal and results in a better, more evenly distributed airflow.

When Something’s Wrong

To know something is wrong with your heating system, you must first understand what temperature air normally is when distributed through the vents. This will vary depending on which room you are in and how big your home (and furnace) are. However, if you notice a sharp drop off in comfort level in your home, it takes longer to heat rooms when cold or if that heating is suddenly uneven, it may be time for someone to inspect your furnace and check for potential problems.

A technician will then check to see if the air is being heated to the target 140-170 degrees F or if heat is being lost in the air handler or ductwork. There are a number of issues that can contribute to lost heat in your heating system – the easiest way to be sure the problem is solved properly is to call an Austinburg professional when you notice the problem.

Solon HVAC Contractor Tip: Causes of Delayed Furnace Ignition

Wednesday, December 21st, 2011

Delayed ignition is usually accompanied by a loud banging or booming sound that resembles a small explosion in your gas appliance. In your Solon home’s furnace, this can be terrifying and should never be ignored.

What Causes Delayed Ignition

Delayed ignition usually happens when you first turn on your furnace, often after a long delay between use, so usually early in the fall or late in the spring when you don’t necessarily have it on every day of the week.

What happens is moisture builds up over the course of a period of inactivity and begins to corrode the firebox in your furnace. That corrosion builds up to the point that it starts to block the ports that feed gas into the burners. When these ports get blocked, the burners down the line cannot light and when you flip the switch, they won’t light immediately.

Of course, while rust and corrosion are a risk, lint and dust can be equally problematic (and are more common if you don’t have your furnace cleaned properly each fall). Sulfur build up is also a possibility, as it is left behind by burning natural gas. It will appear as a layer of white on the surface of the burners or the pilot light.

When all of this happens and the ports are not cleaned properly, gas will build up in the chamber after it is turned on and, when it finally ignites, create the small boom sound. It doesn’t just sound like an explosion – it is one – and if ignored, it can become incredibly dangerous.

Solving the Problem

Delayed furnace ignition is an easy problem to avoid. All you need to do is have your furnace cleaned properly before turning it on each fall. A technician will clean the burners and ports and remove any dust, lint, rust or sulfur buildup that might block ignition and cause a delay.

When replacing your furnace, look for a device with corrosion resistant materials. You can learn more about these when it comes time to replace your furnace from a technician. Most importantly, be careful. It may be a small problem now, but if left to build up over time, that small boom can become a much larger one.

A Roaming Shore Contractor Tip: What to Check If Your Furnace Isn’t Lighting

Friday, December 9th, 2011

If your furnace isn’t lighting properly and your family is starting to suffer because of it, there are a number of possible problems you should check for before calling a Roaming Shore heating contractor. Some of these issues can be fixed quickly by you while others may be signs of a serious problem that needs professional attention right away.

Checking the Pilot Light

If you have a gas furnace, the first step is to check the pilot light and ensure it is still working properly. If the pilot light is still on but goes out when you try to light the furnace or simply won’t stay on when you relight it, you may need to have the gas valve replaced. In some cases, it is as simple as the pilot light not being large enough and the gas blowing out the light.

This happens when gas enters the chamber and doesn’t ignite right away. When it does ignite, which happens after more gas enters the chamber, the extra force of the ignition will blow out the light. This is still a problem and should be inspected to ensure you don’t have any potential gas related issues.

Still Not Lighting

If you don’t have a pilot light or the unit still isn’t lighting, it may be an electrical issue. Electrical ignitions for gas furnaces should spark when the thermostat is turned on, so if it doesn’t you know that the switch or relay are bad.

If you smell gas or anything similar in the room where the furnace is located, you should immediately turn off the unit and call your gas company, followed by a technician. There could be a leak causing low pressure that results in your pilot light going out. Whatever the case, you need someone to look at it immediately.

Your furnace should always turn on when you flip the switch and if it does not, assume there is a problem. If you cannot find the problem yourself and easily fix it, you should call a professional. The risk inherent in an improperly working furnace (especially gas or oil) is too high to ignore.

A Guide from Madison: What Does a Furnace Fan Limit Switch Do?

Wednesday, December 7th, 2011

When researching your Madison home’s furnace and potential problems it might have, you’ve probably run across a few references to the fan limit switch. And while you know that it can break in a number of ways, do you know what the switch does and what you should look for when checking your furnace its air handler for problems?

What the Limit Switch Does

To put it very simply, the furnace fan limit switch is a control that tells your furnace’s fan when to turn on and off. So, when the furnace isn’t on, it tells the blower not to operate (and send cold air into your home) and when the furnace is on, it tells the blower to turn on and start circulating the warm air.

While the primary function of the limit switch is to turn the blower fan on and off, it also has a safety role. When the temperature in the air supply plenum gets too hot, the limit switch turns off the furnace boiler to keep there from being any damage from overheating. This is handy if there is a blockage in the air vents or the controls are messed up due to water damage or improper adjustments to the settings.

Looking for Problems

Most of the time, when there is an issue with your furnace turning off or on frequently, the limit switch is one of the first things you will check. Because the switch is electronic and is attached to a thermostat which measures temperature in the air supply plenum, a small problem can result in it not working properly. So, you can easily check it by temporarily bypassing the switch and seeing if your device turns on or off properly.

In many cases, if the limit switch is the problem, you will still need to call a professional for replacement, but you can avoid a lot of headaches related to tracking down the source of the problem. If you suspect a limit switch problem, make sure to call someone immediately, because it does provide an important safety function and because without it your furnace won’t cycle on and off properly.

A Question from Kirtland Hills: Why Does My Furnace’s Pilot Light Keep Going Off?

Monday, December 5th, 2011

If you have an older furnace with a gas pilot light and it keeps going out, heating your Kirtland Hills home can become a frustrating process. Not only are you forced to trudge downstairs to light it every time you need heat, but you’re probably starting to worry that there is something wrong – either with your furnace or with your gas supply. Here are some possible reasons for your pilot light shutting off and what you can do about them.

  • Thermocouple – The thermocouple is used to generate electricity from the gas being burned by the pilot light to power the sensor that keeps the pilot light running. So, if the thermocouple goes bad or gets blocked in some way, the sensor won’t work properly and your pilot light won’t remain lit. Even a small problem with the thermocouple can lead to the valve closing and the pilot light going out.
  • Gas Pressure – If the gas pressure going to your furnace is too low, due to a leak, pipe problem or another appliance, the pilot light may not have enough gas to stay lit. While it is possible that the problem is not related to gas pressure, anything that affects the flow of gas into your home should be inspected by a professional. If you smell gas, leave the house and call your gas company immediately.
  • Mercury Sensor – The sensor in your pilot light that maintains the flow of gas to keep it lit can go bad. Keep in mind that these sensors almost always used to contain mercury (and often still do), so you should be careful with them. It’s best to call a professional who can replace and dispose of it properly.
  • Dirty Burners – Excess dust, lint, rust or sulfur build up can result in blockage of the burner holes. When this happens, gas will flood into the chamber but not light right away. When it does finally light, it will create a small boom or banging sound that will often put out the pilot light. Not only is this inconvenient, it is very dangerous. Fortunately, it can be avoided with annual cleanings of your furnace.

The best way to keep your pilot light lit at all times is to have someone inspect it once a year. If something happens in between, you can usually rule out cleanliness issues and call in a professional to check the thermocouple and sensor.

What to do if Your Heating System Breaks: A Tip from Bainbridge

Monday, November 7th, 2011

What if the heart of your Bainbridge home’s heating system – the furnace – stops working? The warm air that used to flow from your vents has been replaced by a chilly draft. It isn’t time to panic, but it is time to take action. Before you do anything, determine why the furnace stopped working. It may be something as simple as a tripped circuit breaker in your electrical panel. Check the circuit breakers first.

The pilot light in your furnace may have blown out. It can be re-lit if you follow the directions in your furnace owner’s manual. You can find answers on how to re-light a pilot light on the Internet, too.

If the shutdown has not been caused by an electrical or pilot light failure, there is still no need to panic. But another obvious question is: did you pay your last gas bill? Maybe you had a shutoff notice and either ignored it or forgot about it.

Now that you are convinced that the furnace has pooped out, here are some things you should do. First, find the name of a qualified heating and cooling professional. If you already use a heating contractor, contact them and schedule a service call.

While you are waiting for help to arrive, ensure that everyone is safe and accounted for. Make sure pets are nearby and protected from the cold, too. What you don’t want to do is use any appliance to keep you warm that is not designed to keep you warm, like a stove. If you have electric space heaters or propane heaters, carefully locate them in a well vented room (windows open a bit or portable fans circulating air). You don’t want any build-up of gases from fossil burning appliances, gases which could contain deadly carbon monoxide.

Huddle up everyone into a room and break out lots of blankets. You may even want to make an “adventure” of this – find a movie to watch and pop up a bunch of popcorn.  If your waiting time is more than 24 hours, you might want to call up a friend or relative and make arrangements to spend the night with them.

The main thing to remember is not to panic. Most qualified heating contractors, knowing the circumstances, will send out a repair person in a matter of minutes or within one or two hours. Just remember to avoid keeping warm by using unvented heating devices.

How Do I Check a Gas Furnace Draft Pressure Switch? A Question from Jefferson

Wednesday, November 2nd, 2011

There are many reasons why a furnace stops working and in many cases, any Jefferson homeowner can perform some simple diagnostics to pinpoint the problem. Finding the problem is one thing – fixing it is another. When in doubt, don’t try it yourself. Call a qualified professional.

But let’s look at one possible problem and solution you may be able to perform yourself – testing the draft pressure switch. The draft pressure switch on a gas furnace allows an electrical current to pass through to ignite the furnace. The pressure switch monitors the draft conditions and won’t allow the furnace’s gas valve to open unless draft is correct.

If the switch is malfunctioning, so too will (or will not) the furnace.

The best way to locate the switch is by consulting with your owner’s manual or by going online and simply typing in the words “gas furnace draft switch.” It is identifiable by its round size and is bolted to the outside of the furnace. It should be nearby the draft inducer motor because the two are connected by a metal tube. The tube may sometimes be the culprit, too. A tube that is blocked with condensation may cause the switch to go bad.

To check for proper function, first turn off power to the furnace, either by shutting down the “on’ switch at the furnace or shutting off the circuit breaker.

Use a volt ohm meter to check if the switch is opening and closing properly. Start by zeroing out the meter’s probes by touching the tips together. Using the dial (could be analog or digital), set the meter to 24 volts. Ground the black probe by attaching it to any metal part of the furnace. Then place the end of the red probe on the metal tube connecting the draft pressure switch to the draft inducer motor.

If the switch is working properly the meter should read at least 24 volts, or very near that. If the reading is short of 24 volts, the switch is not working correctly. At that point you may decide to replace it or call a professional to do the task (recommended).

Always remember that there are many sources which will help you diagnose and repair a problem, especially those available through the Internet. If you search YouTube.com you will find many videos advising you on how to repair certain components. Use all of the resources available to you and keep the phone number of a qualified and professional heating and cooling contractor nearby.

Common Furnace Problems: Some Tips From Austinburg

Friday, October 14th, 2011

When it comes to the furnace in your Austinburg home, you simply want it to work all of the time. But just like any other piece of equipment, your furnace will have problems from time to time. A few of these are relatively simple to fix on your own, but for the most part you’ll need to call in someone to take care of the repairs for you.

However, before you can do that, you’ll need to recognize that a problem exists at all. And the earlier you notice the warning signs, the better off you’ll be. It’s always better to get a furnace problem taken care of right away than to wait until your furnace stops working completely.

It’s also good to remember that quite often the problems you’re having with your furnace are really originating with your thermostat. This is usually welcome news, as thermostats are much cheaper and easier to repair and replace than many other parts of your furnace. In fact, even if your furnace isn’t working at all, it may only be the result of a faulty thermostat.

Another problem you may start to notice is that one part of your house is being warmed more than another part. When this happens, it can be a sign that there is something wrong with the furnace, but it may also be that the pressure in your duct system is not balanced properly. A simple rebalancing of this system can have your house heating evenly again in no time.

You may also realize that your furnace seems to be cycling on and off too often. When a furnace is working properly, it will come on for a considerable period of time and then shut off until the temperature in the house drops below the desired level. However, some problems can cause your furnace to complete many short cycles rather than fewer short ones.

If this is happening to your furnace, there are several possible causes. Something might be wrong with the blower on the furnace or the thermostat might not be feeding the furnace the correct information. Another possibility is that your furnace’s air filter is dirty or clogged.

While there are sometimes simple and straightforward solutions to these types of common furnace problems, it’s best to call in an Austinburg professional to have them take a look if you’re not sure where to start searching for a problem. In most cases you’ll need them to come out and make the necessary repairs anyway.
