Even though the summer brings high temperatures, don’t let it bring high electric bills with it as well. Did you know that you could find huge savings on your electric bill in your attic? With functioning attic ventilators, savings can be yours. Let the experts at Mr. Electric® help you understand what method will be of greatest benefit to you.

Brad Richards with Mr. Electric of Tucson offers his expert opinion on attic ventilators and will explain how to save money on your electric bill in the summertime.

Mr. Electric: What exactly does an attic ventilator do?

Brad Richards: An attic ventilator fan is essential in the summer because it evacuates the hot air that accumulates during the day from the attic and draws air in from the outside. Think of it as a means of cycling the trapped air out with fresh air from the outside. It ensures that the temperature of the air in the attic is closer to the air temperature outside. With stagnant air, the sunlight on the roof heats the air inside the attic greatly. It is best to evacuate that hot air in the summertime so that you can save money on your cooling. If you’re air conditioning unit (A/C) is running and you don’t have a functioning attic ventilator, your attic is acting like a radiant heater while you’re A/C is trying to cool the room at the same time. Essentially, they are working against each other and costing you more money.

Mr. Electric: What are the different types of attic ventilators?

Brad Richards: There are two types. One of them is a roof-top unit that draws air directly out through the roof and pushes outside air into the attic to regulate the temperature. The other type is a 120-watt gable fan system. This system consists of one fan that blows air into the attic and another fan that blows air outside, creating airflow that is constant to reduce the temperature in the attic. The gables are triangular in shape and are located on opposite ends from each other on the sides of the attic.

With both types of ventilation systems, there is a solar option. The system that we recommend most often is the roof-top solar fan. Hot air rises and the fan tends to pull the air up and out of the attic, while both gable openings are open for the fresh air to come in. This is the most efficient and best money saver because when the sun comes up, the solar cells power the fan and the fan speeds up the more the sun becomes more direct. Then, when the sun goes down, it naturally turns itself off because there’s no more direct sunlight on the attic.

Mr. Electric: What are the benefits of a homeowner installing an attic ventilator?

Brad Richards: The number-one benefit of having an attic ventilator in the summer is you are able to keep your home cooler for less money. Solar-powered fans offer an even higher return on investment because you aren’t paying for electricity to run the fan. Using natural sunlight to cool your attic is a great way for homeowners to save money in the process.

Mr. Electric: Do you have any additional tips or recommendations?

Brad Richards: Regardless of whether you choose roof-top vents, gable fans, or solar powered fans, any home in the summer would benefit from attic ventilation. In other words, if you have an attic, there is a benefit to having ventilation.

As a Top Plano Electrician, I know better than anyone how powerful and useful electricity is. It also makes me more aware of what most people tend to ignore or forget: electricity is dangerous. Electricians are required by law to carry insurance, and for good reasons. Electric current is capable of starting fires and destroying your property and equipment in a matter of moments. The proper safety precautions really can save lives, and there‘s always something we can do to improve home safety.

One of the most important precautions is located in your electrical panel: the circuit breaker. It is designed to keep you from using more electricity than the wiring or receptacle can handle at one time, what we refer to as overcurrent protection. This protects your wiring from taking on too much current, which can cause the coating around your wiring to melt, the leading cause of electrical fires. Circuit breakers serve another purpose as well; not only to protect from surges coming from outside your home, but from potential hazards within it as well. Current flowing through a failed piece of equipment or appliance can cause sparks, which have the potential to start fires or damage other electrical devices. A properly functioning circuit breaker can shut off the power to this device. It’s very important, however, that you use a circuit breaker of the proper size for the circuit to ensure that your wiring is properly protected.

Circuit breakers come in specialty varieties as well; the most important are ground fault circuit breakers (GFCI), for wet locations, and arc fault circuit breakers (AFCI). AFCI’s, in particular, can help prevent some of the most common dangerous situations in your home.

I’ve dealt with plenty of cases where electrical fires have started because people ran an extension cord under the carpet, so that they can power the lamp in the center of the room. Over time, people walking over the cord stretches out the wiring, making it so thin that the current overloads the thinly stretched wire, creating an arc fault; the electricity “jumps” the wire, completing the circuit in a way the cord can’t handle and generating heat that starts a fire. Arc fault circuit breakers prevent this by shutting the circuit down when the arc fault occurs.

So what do you need to know about arc fault circuit breakers? To start with, by code AFCI’s should be installed on any circuit that isn’t protected by a GFCI or directly wired into an appliance. It’s in your best interest to have your safety devices routinely inspected to maintain their optimum performance and capabilities; in particular, your circuit breakers should be inspected at least once a year. The inspection process is quick and relatively inexpensive, and something that simple really can save the lives of you and your family.

Super Bright LEDs employs skilled engineers and experts to test LED lights before they’re sold. Our in-house test lab is stocked with numerous pieces of equipment that provide important specifications about each product, such as brightness, color temperature, and operating temperature. Testing methods include the use of integrating spheres, spectrometers, Forward-Looking Infrared (FLIR) cameras, and an environmental chamber. In addition to this equipment, our technicians perform burn-in tests and durability tests that can last anywhere from two weeks to several months.

Our state-of-the-art environmental testing chamber utilizes a 30-cubic-foot enclosure to reproduce the full ranges of temperature and relative humidity found within commercial and industrial LED lighting applications. Data collection (photometric & electrical) occurs while a device-under-test cycles through specified environmental extremes. Chamber temperature ranges from negative 35° C (negative 31° F)  to 200° C (392° F), and humidity ranges from 10 to 95 percent.

To ensure that our products will perform under normal and extreme conditions—and to have a little fun—our technicians put them through a round of applicable tests. A selection of LED lights is time tested in the environment that each product is designed for. For example, waterproof boat lights are submerged in water, and weather-resistant landscape lights are installed outside. Depending on the type of product and its impact/weather rating, our technicians might drop, run over, freeze, burn, or even saw it in half to test the product’s durability.
