Gas-powered furnaces are extremely efficient and reliable sources of heat. Some homeowners worry about the safety of these appliances, but the truth is that today’s are built with much better technology that significantly reduces the risk of gas leaks and similar problems. However, one component of your furnace that you do need to be aware of is the heat exchanger. Cracks along this component are a concern and require the immediate attention of a professional, such as any member of our team.

The heat exchanger’s role is to collect the hot combustion gas from the burner and transfer the heat to its metal walls, where it transfers to the current of air from the blower. This keeps fumes from the combustion gas away from the air that moves into the ventilation system, reducing your exposure to said fumes. Once the combustion gas cools, then it vents out of the heat exchange and safely up the exhaust flue, and out of your home.

Gas furnaces do not use water, but corrosion and rust can still occur. This is because they are a natural reaction between metal and combustion gas. When corrosion begins to form on an aging furnace, it’s usually a sign that it’s time to start thinking about a replacement. However, if your furnace is on the newer side, then you could have a problem with proper exhaust venting, which can cause corrosion on the exchanger—weakening it until it cracks.

What happens when your heat exchanger cracks? Well, it will start to leak combustion gas into the furnace cabinet, and this is where the danger lies when using a gas furnace. Carbon monoxide gas has a high toxicity and potential to make you and your family very ill. To be on the safe side, if you see any signs of corrosion on your furnace whatsoever, it is best to call in our professionals for inspection.

Energy deregulation gives consumers choices when it comes to the companies that provide their home electricity. Suppliers can compete for your electricity dollars in a variety of ways, offering low prices, short and long-term contracts, fixed or variable rates, and a choice in how your energy is generated. The sheer volume of options can seem so complicated that you need to ask an electrician to help you tangle out the pros and cons of the available plans. One area in particular that can trip up consumers has to do with whether the source of their electricity is green or renewable. Read on to learn the difference.

Green Customers are Loyal Customers

Currently, 15 states plus Washington, D.C. have active electricity deregulation programs, according to the U.S. Energy Information Administration, and these states are largely concentrated in the Northeast. Consumers who live in deregulated states are likely to be flooded with energy offers, often promising electricity that is derived from green or renewable sources. Purchasing this environmentally friendly power usually costs a bit more than electricity that comes from more traditional sources like coal, but some homeowners like to put their money where their mouth is when it comes to reducing carbon emissions.

Those customers who go green are valuable to the supplier because they are less likely to jump ship based on the availability of a cheaper energy source. "A customer on a renewable-energy product has actively decided what is important to them and has selected their supplier accordingly," Ritchie Hudson, Pennsylvania chairman of the Retail Energy Supply Association, said to the Philadelphia Inquirer.

A Question of Semantics

However, while many suppliers and consumers treat green and renewable sources of electricity as synonymous, there is a distinction. Green energy is that which comes from specific sources that have the highest environmental benefit, including solar, wind, geothermal, biogas, eligible biomass and small hydroelectric sources, according to the Environmental Protection Agency. Meanwhile, renewable energy “includes resources that rely on fuel sources that restore themselves over short periods of time and do not diminish,” which includes all the green options but also other sources such as large hydroelectric dams, which present certain environmental tradeoffs.

That means that if you really want to limit your impact on the Earth as much as possible, go green in lieu of simply choosing renewable energy. You can further refine your choices by asking about the specific source of the electricity, if you have a preference for solar, wind or another option.

Ask an Electrician About Your Options

Deregulated energy markets give you flexibility, but can also sow consumer confusion. If you need help deciphering the offerings of your state's electricity providers, ask an electrician who can walk you through your choices.

You've done everything you can to conserve energy in your house -- purchased the latest Energy Star appliances, insulated your walls, and turned your thermostat down to 68. But the next thing you know, your kids are leaving lights on in rooms they aren't occupying. Or staring into the refrigerator for minutes on end while all the cold air escapes through the open door. Or nudging the thermostat higher when you aren't looking. How can you convince your kids to help, not hinder, your efforts to cut down on energy usage?

Knowledge is Power

Your children can't make the effort to save energy if they don't know how. Help them start building good habits early, and make sure they’re aware of simple ways they can help lower the utility bills:

To save electricity:

To conserve water:

To keep your heating and cooling bills low:

What if They Don't Wanna?

Of course, every parent knows that telling your kid to do something doesn't mean it's going to happen. The trick is to get them to buy in. While one reason to conserve energy is to save money on your utility bills, children have a habit of taking mom and dad's money for granted, so that might not be your most persuasive argument.

Instead, try teaching them about how human reliance on fossil fuels is harmful to the environment -- but they can help make a difference. If your children have particular interests, like animals, you can tie the themes together -- tell them they can help protect animal habitats by doing their part to conserve energy.

Another trick is to give them a green light to correct you if you make a mistake like leaving the water running. That gives the kid some fun responsibility, and encourages them to be vigilant about your behavior -- which increases the likelihood they will be about their own.

Check out the Energy Star Kids program for more ideas on how to persuade your kids and get them excited about conservation, and for child-tailored activities to increase their knowledge and motivation. And remember, the best way to teach your kids how to conserve is to set a good example by doing it yourself.
