Antique architecture might be beautiful, but the electrical wiring in old houses doesn’t carry the same kind of charm. If you have an older home with an electrical system that hasn’t seen updates in a long time, you could be living in dangerous conditions without realizing it.

There are warning signs that may indicate your wiring is too old, but if you’re ever in doubt, there’s a fool-proof way to get an assessment of your system: Call in a professional! An expert will perform an in-depth inspection of your home’s wiring so you can be aware of the situation and the solutions for it.

With outdated wiring, you may notice strange signs from time to time. Some of them might occur with more regularity than others, but any instances at all can be cause for concern. In general, you’re at risk for having old wiring if your house is 40 years old or more. A few warning signs include:

Although old wiring can raise insurance premiums and keep you from using as many appliances as you’d like, the most important issue is safety. Over the course of time, the insulation surrounding the wires will break down until it eventually leaves the wiring exposed. The insulation protecting older wires doesn’t last as long as it does in newer installations. This means outdated electrical systems are much more likely to feature exposed wiring than those installed more recently.

With inner wiring exposed, the likelihood of short circuits and power failures goes up. Worse, deteriorated insulation translates to a much higher risk of suffering from electrical shocks or having fires break out in your home.

If you have any doubts about the wiring in your house, don’t take unnecessary risks. Ignoring the warning signs of an outdated electrical system can put you and your loved ones in danger. Beyond that, whatever money you might hope to save by not calling a professional would only go into repairs later on.

If you're looking to increase the efficiency of your home, there's some good news: Not only can you save a bundle of money with lower utility bills, studies show that you will be able to sell your house faster, and for more money as well. Green houses are attracting more attention on the market, so when it does come time to sell you could see a big increase in the price.

Decision Influencers 

Efficiency matters. Ninety percent of potential homebuyers rate home efficiency features as “very important,” according to a survey by the National Association of Homebuilders. The survey went on to report that 61 percent of buyers would pay up to $5,000 more for a house that promised lower utility bills. Other studies found that green-certified houses sell for $34,800 more than similar homes without efficiency features in California, and green houses in Seattle, Wash., and Portland, Ore., sell at a premium of 8.5 percent and 12 percent, respectively. The Seattle study also found that the green homes sold 22 percent faster than others.

Make sure your realtor is aware of all the efficiency upgrades you’ve made and can highlight them to interested buyers. If you provide old utility bills you can really showcase the savings. 

Keep that Electric Bill Low

The electric bill is one of the biggest ongoing household expenses, so any reductions you make will go a long way. There are a lot of places to look for savings. For starters, if you have old, outdated appliances, replace them with new Energy Star-certified models so you know that they meet the strictest efficiency standards. Your lighting system is another place to upgrade -- it's time to toss old incandescent bulbs and replace them with compact fluorescents or LEDS. Finally, if you really want to save money and make your house look good to buyers, install some solar panels on the roof, which can reduce the electricity bill to near zero. 

How Else Can I Increase My Efficiency?

Don't forget to take other steps to increase the energy efficiency of your home, especially when it comes to heating bills:

You can also hire a qualified professional to conduct an energy audit and point out other ways to increase your efficiency and save money. Even if you don't plan on selling your house any time soon, you can enjoy seeing the savings in your bills each month.
