What Is “Too Old” for a Furnace?

Monday, January 27th, 2020
Furnace-standard

No furnace can last indefinitely, and there’s no such thing as “the last heating system you’ll ever need to buy.” Even in warm Southern California, furnaces gradually wear down from use. In fact, homeowners often neglect to have routine service for their furnaces because they don’t rely on them often. This will speed up the furnace’s decline.

If you’ve come to this post, it’s because you suspect your furnace is past its expiration date—whatever that may be. What is considered “too old” for a furnace? We’ll take a look at this question, which has several answers.

How to Prevent Furnace Short Cycling

Monday, February 15th, 2016

Short cycling is one of the most dangerous problems that can afflict any climate control system, including furnaces.

If you want your furnace to live a long and healthy lifespan, you should do everything you can to prevent it from short cycling. There’s one very simple way to make sure that your furnace is unlikely to short cycle. Read on to find out more about that method.

The Heat Exchanger: The Secret of a Furnace’s Success

Wednesday, January 7th, 2015

Furnaces have a number of components that help them to operate safely and effectively, but there are 3 key components that could be dubbed the “workhorses” of the system: the blower, the burner and the heat exchanger. While every component is necessary, should a problem develop with any of these 3, you most likely won’t have any heat, or won’t have safe, sufficient and efficient heat. Today we’re going to talk about the heat exchanger: how it works, why it’s important and how a cracked heat exchanger can be a serious problem. But remember that for any furnace repair issues you may have in Orange County, the experts from Saddleback Plumbing are always available.

What Is a Heat Exchanger?

The heat exchanger in your furnace is a medium-sized, serpentine component that sits directly above the burner. The tube of the heat exchanger is open at both ends, which allows the toxic combustion byproducts to enter at the burner level and exit through the flue, which is connected to the top of the heat exchanger. The warm air that is generated on the outside of the heat exchanger is the warm air that is blown into your home.

Why Does a Heat Exchanger Work Like This?

The heat exchanger is the component that separates the toxic byproducts from the combustion, including carbon monoxide, from the warm air; without it, these byproducts would be blown into your home along with the heat.

Why Is a Cracked Heat Exchanger Dangerous?

Heat exchangers have an average lifespan similar to that of your furnace: about 15-18 years. The heat exchanger is constantly heating and cooling, which causes the metal to expand and contrast regularly throughout the winter months. After years of this action, cracks can develop in the heat exchanger. The reason this is dangerous is that a crack in the heat exchanger can allow the toxic byproducts to escape and enter your home, including carbon monoxide. Heat exchangers can’t be repaired once a crack develops, but they can be replaced.

The best way to ensure that your furnace is repaired properly is to hire a professional. The trained and certified experts at Saddleback Plumbing are available for any furnace repair in Orange County that you may have, so if you are experiencing problems with your furnace, call us today.

Woodbridge Heating Guide: Furnace Fan Limit Switch

Friday, January 13th, 2012

When researching your Woodbridge 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 Woodbridge 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.

Common Garden Grove Furnace Problems

Monday, January 2nd, 2012

When it comes to your home Garden Grove furnace, 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 Garden Grove 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 a Garden Grove 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.
