"Ralph and Ralph Jr were a pleasurer to work with. They did a great job installing TVs and mounts at all of your medical clinics. They were very responsive to all of our questions and gave us exactly what we were looking for. They stand by their work and will make sure everything is done to your satisfaction. I would hire them again for any other installation, electrical, or networking work we need for our business."

"I would highly recommend Four Seasons! I recently scheduled duct and furnace cleaning. The technician quickly identified an issue that necessitated purchasing a new furnace. I opted to also upgrade my AC at a bundle rate since it was over 25 years old. The duct cleaner and professional installers were extremely knowledgeable, friendly and worked efficiently to both clean my ducts and install my new furnace and AC expeditiously. I immediately realized a huge difference in my heat and air quality which I am sure will result in savings on my electric bill. I have even scheduled some electrical work through Four Seasons and plan to use them going forward for all my Heating, Cooling, Plumbing and Electric needs."

"They showed up at 8:15 am (appointment was for 8:30-9:00 am)  Prior to the appointment we were told this would take 5-6 hours.  They were completely done by 11:15.  They placed the unit, installed the gas service, installed and configured the transfer switch, tested the fail-over and fail-back, checked all pilot lights in the house and gave an overview of the operation of the unit and there 24/7 service agreement.  All in all, we could not have asked for a better experience.  I would recommend them to anybody looking for a stand-by electrical generator system.

Electrical FAQs, answered by experts

No, because amps and volts measure very different things. However, you can use basic equations to find amps or volts by using data about one of the measurements to calculate the other.

Most LED bulbs have a plastic covering, while incandescent bulbs will be made from glass. This is because LED bulbs don’t produce as much heat as incandescent bulbs, so the covering doesn’t need to be as heat resistant. Also, an LED light bulb will usually have a marking on its base that identifies it as an LED.

An electrician will charge between $100 to $150 to install a new light switch. Whether you need to cut into the wall and repair drywall will determine your final project cost, as you can expect to pay $50 to $75 per square foot to repair drywall.

Services by electricians can quickly get expensive, but there are a few ways you can save money in the process:

  • Bundle multiple jobs done at the same time to save on trip fees or flat fees for individual projects.

  • Get at least three quotes for service to find the best deal.

  • Buy fixtures, switches, outlets, and other materials beforehand to avoid product markup.

  • If you feel comfortable with it, have an apprentice or journeyman complete the work under the supervision of a master electrician. These electricians in training tend to charge less per project.

A 60W LED bulb is likely labeled as “60W replacement” on the package—that’s because it provides about the same light output as a 60W incandescent bulb. In reality, it likely uses less energy—usually 15 watts or less. If that’s the case, then it’s perfectly fine to put a 60W LED bulb in a 40W socket. Your best bet is to read the package carefully. It will tell you the LED bulb’s actual wattage, and as long as it’s lower than the fixture, the bulb will be safe to use.
