A significant number of homes in Baltimore and Bethesda, MD, Alexandria, VA, and Washington, DC built between the mid-1960s and the first half of the 1970s have hazardous aluminum wiring rather than copper. During that time, aluminum wiring was considered safe to use and viewed as a cost-saving measure. The U.S. Consumer Product Safety Commission (CPSC) now believes aluminum wiring poses a safety hazard in homes that still have this type of wiring.

The biggest danger associated with aluminum wiring is that unanticipated fire hazards arise from the oxidation and deterioration caused at the points where aluminum wiring is connected at outlets, light fixtures, and splices. While this can cause overheating and arching that won’t trip a circuit breaker, it can cause a fire. Aluminum wiring was used in an estimated 2 million homes between 1965 and 1973—and many of these homes are located in the MD, VA, and DC area.

If you’re concerned about dangerous aluminum wiring, pay attention to the following warning signs:

All of these signs indicate a potential fire hazard for standard aluminum wiring.

Aluminum wiring should be thoroughly evaluated by a qualified electrician who is experienced in inspecting and correcting wiring problems. The CPSC recommends a few methods for correction. The first is to rewire the home with copper wire, an expensive option that really only makes sense if the homeowner is already in the process of completely remodeling or doing deep renovations. The second option is to use the Copalum crimp method to correct the problem. This involves attaching a piece of copper wire to the existing aluminum wire with a specially designed metal sleeve and powered crimping tool. It is a permanent repair option that will eliminate the dangers posed by aluminum wiring. A third option is to use a UL listed copper to aluminum connector to attach a copper wire to the existing aluminum wire.

Only an experienced electrician can accurately determine the level of danger a home with aluminum wiring faces, and then fix the problem in an efficient, timely manner.

It may not officially be winter yet, however temperatures have declined to the point that we can no longer deny it is on its way. Over the years, we’ve seen the news about homes and families—even locally—who have been stranded for days with no heat or power because of a widespread outage in relation to winter storms.

Crews work as fast as they can when these scenarios occur to get your home back on track. However, they can only work so quickly, and many times the weather doesn’t cooperate as we hope it will so they can get the power back up quickly. Therefore, homeowners are sometimes left without heat, refrigeration, or the use of any important appliances. That is, at least, if they don’t have an effective and efficient whole-house generator.

Have you ever been stuck in the middle of winter with no working heater? Hopefully, the answer to this is no, and also hopefully you’ll never have to deal with this. A generator is the leading way to reduce the risk of this happening. Remember, a power outage can very easily take out your heating system, leaving you will chilly weather and no defense against it.

Do any members of your household rely on electrically-powered devices for medical conditions? Perhaps it’s an oxygen breather or some other type of machinery. If so, then a generator can literally be a life-saver for them. There’s no reason to wait on a generator installation if you rely on medical equipment.

As intangible a benefit as this is, it’s still an important advantage. Even if you never face a significant power outage this winter or next, you’ll know that you are well-prepared in case one does happen.

Electricians are often looked upon as professionals that have to be called in only when something isn’t working. However, the fact is that a great, reliable and experienced electrician would also be able to provide you advice on the type of fittings and fixtures or electrical installations that would look good and add functionality to your home.

Regardless of how beautifully designed your home is, if it doesn’t have the right type of lighting that can only make the rest of the features and elements look dull and drab. But you can add accent lighting to various areas of your home to add to its aesthetics and functionality. It’s important to plan the lighting well as it helps create enjoyable and beautiful spaces on your property.

Some light fixtures are used only in areas where specific tasks are going to be carried out such as kitchens, study and home office spaces etc. But in addition to this task lighting, your home also needs lighting features that help accentuate the look of various installations in your home; this is referred to as accent lighting. This lighting includes fixtures such as subtle spotlights, or miniature pot lights.

Accent lights aren’t meant to throw bright light and fill the entire room with light; they are used instead to highlight features such as artwork, paintings, pieces of décor or some interesting architectural feature in your home etc.

These lights are soft and add a very comfortable and elegant look to the space. In fact you can use accent lighting to enhance the appearance of the outdoor areas of your property as well. They can be switched on to create a party mood or lend a more casual look to the common living spaces or alfresco areas of your home.

There are a number of benefits to getting accent lighting installed, such as:

While you can use these lights by themselves to maintain a very casual look in a room, they can also be used in tandem with other lighting installations such as track lighting, recessed lighting, under counter lights, floor level lights as well as spot lights etc.

Since accent lights aren’t meant to be very bright, they use less energy; in fact, you can add to their efficiency by using LED bulbs in them – this can make them up to 80% more energy-efficient that standard bulbs.

There are always some areas in a home that don’t get sufficient natural light; you can install accent lights in these areas, and these fixtures look great in basement entertainment rooms as well. You can choose outdoor-grade accent lighting fixtures to add to the beauty of your patio, deck or outdoor kitchen as well. The light that these installations throw lends a very luxurious and relaxing look to these spaces.

More people have been thinking of trying to switch from oil-dependent vehicles to electric cars. However, many of the same individuals are also intimidated by the numbers of gas vs. charging stations available near them. While this might not be a problem in larger cities, more rural locations can run into charging issues. This is why charging your vehicle at home is so important. Around 88% of electric vehicle drivers refuel at home or at work.

Depending on your car, you might need different levels of charge. A level 1 charger uses wall sockets in the average home. However, 1 charge could take about 22 hours to complete. A level 2 charger is a little better. It works with a 240-volt wall outlet and can give you around 70 miles per charging hour. You can use the same outlet as your washer and dryer, but having a dedicated outlet for your car can help you prevent potential problems from alternating electricity flows.

A level 3 charger is the fastest and most efficient option for charging an electric car. Level 3 chargers, also called DC fast chargers, use a special charging port to get power to the battery while bypassing the car’s onboard charger. With this kind of station, you can fully charge your vehicle in a half hour.

When you’re shopping for new heating and air conditioning equipment, you may want to give a second thought to a heat pump. Heat pumps use electricity to heat a home, but they do not use nearly as much energy as conventional electric furnaces. Plus, a heat pump is primarily an air conditioner, so you get an all-in-one system that requires less maintenance and works more efficiently.

Want to know more? Our heating and AC technicians are here to answer all of your questions and make sure you end up with the right home comfort equipment for your home. For more information, contact our friendly technicians, and read on for a brief overview of the heat pump system.

A heat pump uses your central duct system to move heated or cooled air out to the various rooms of the home. It also has an outdoor compressor unit, just like a conventional whole-house air conditioning system. The indoor unit is joined to it by the refrigerant line.

Refrigerant is a chemical blend capable of moving heat from one place to another. When in cooling mode, refrigerant absorbs heat from the inside of the home and moves it outside. That’s how the cooling process is started.

A reversing valve works along with some other parts to give a heat pump the ability to switch into heating mode. The refrigerant can work in reverse and also absorb heat from the outdoors and move it inside for whole-home heating.

What makes a heat pump so efficient is that the process of moving heat from one place to another uses so much less energy than the process of generating heat (like furnaces and boilers do). When you examine other electric heaters, like portable units and electric furnaces, there is no comparison in the amount they are able to save each month.

Sometimes, a gas heating system is a better option. Efficiency does suffer as temperatures drop, and the cost of gas heating is typically lower than the cost of electricity. Ask a technician to help you decide what the best choice is for your home.
