Electrical FAQs

Answers From the Experts!


Q: Why do my smoke detectors keep beeping?

Answer: If a smoke detector keeps beeping, chances are you will need to replace its battery. The batteries in your home’s smoke detectors should be replaced annually to ensure maximum safety. But, if a battery is low, your smoke alarm will beep intermittently until the battery is replaced.

Q: Can I do my own electrical work?

Answer: There is no right answer to the question of “Can I do my own electrical work?” The answer depends on the electrical issue at hand. For example, changing a bulb or fixing a tripped breaker an easy fix for any homeowner. However, DIY electrical work can be very dangerous. If you’re unsure what your electrical problem is, we recommend calling an electrician to diagnose and repair your electrical issue. Otherwise, you risk personal injury, electrical fire, or even death.

Q: Why do my lights flicker at home?

Answer: Flickering lights are annoying and may be a sign of a potentially dangerous electrical problem, or something simple – like a bulb that is on the fritz. If replacing a light bulb doesn’t work, call an electrician right away. Your flickering lights could be due to loose wiring and lead to an electrical fire.

Q: How do I reset a tripped breaker?

Answer: A tripped breaker is a nuisance. When it trips, an entire electrical circuit will not work, causing any electrical appliances or devices to not work as well. To fix it, follow the steps below:

  1. Locate your circuit breaker panel (usually found in your basement, garage, or closet).
  2. Locate the tripped breaker. This is indicated by a breaker that is switched to the “off” position (not aligned with all the other breakers) and usually displays a red or orange color.
  3. Reset the breaker by flipping it to the “off” position. Then, switch the breaker to the “on” position (you should here a clicking or snapping noise when it is properly in place).

Q: My breaker keeps tripping, what do I do?

Answer: If the same breaker trips again and again, call GAC Services. You may have too many electrical appliances and/or devices plugged into the same circuit, resulting in an electrical overload and causing your breaker to trip. Or, you may have a deeper electrical issue on your hands. A GAC electrician will help diagnose your issue and recommend a plan of action to fix your breaker.

Q: Why is my breaker panel hot to touch?

Answer: If you find your breaker panel is hot, it is most likely overheating. This is a serious problem that could cause arcing in the breaker and needs to be replaced ASAP.

Q: What does GFCI stand for?

Answer: GFCI stands for “ground fault circuit interrupter.”

Q: Where should I install a GFCI protected outlet?

Answer: GFCI outlets should be installed in wet areas throughout your home. These include unfinished basements, garages, any outside outlet, bathrooms, kitchens, and anywhere within six feet of any sink.

Q: What are the buttons on my GFCI outlet for?

Answer: Your GFCI outlet includes two buttons – a Test button (black) and a Reset button (red). Pushing the black test button will turn off the outlet and all other outlets within its circuit. The red Reset button turns the outlet (and all others included within the circuit) back on.

Q: How can I lower my electric bill?

Answer: Lowering your electric bill is not a one-time fix. You must first change your daily habits. Be sure to turn off all lights or electrical devices not in use when leaving a room – like TVs. If you have outdoor lighting, install a timer to make sure it is only on when necessary. If you have a heat pump, electric furnace, or air conditioning system, try keeping a consistent thermostat to so your HVAC system runs for shorter periods of time, ultimately reducing the amount of electricity consumed. Lastly, you can also set your thermostat slightly lower in the winter and higher in the summer to reduce HVAC operating time.
