"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

The National Electric Code states that outlets should not be spaced more than 12 feet apart, and there should be an outlet placed every 6 feet at the floor line in areas designated as living spaces. Most homes in the United States have 75 outlets, but it will depend on the amount you need based on your home's size and your needs.

It prevents electrical surges, protects your home from things like electrical fires, and prevents you from getting shocked if an errant surge runs through your power line. Without grounded wires, your appliances could also get damaged during lightning storms.

If you find the power cables for your appliances are too short, there are ways to extend them for the cost of just the extra wiring you need. Simply cut and strip your wires, solder them together, and cover them using heat shrink tubing. Not everyone has a soldering tool on hand, so if you’re looking to extend in a pinch, an extension cord, power bar, or surge protector can do the job just fine.

Watts and volts represent distinct aspects of a light bulb’s functionality. Volts measure the electrical force that drives the current through the bulb, determining its compatibility with the power source. Watts, on the other hand, quantify the bulb’s power consumption and indicate its brightness level. Higher watts generally mean a brighter bulb.

No, outdoor outlets are not required to be on a separate circuit. However, you should always defer to local electrical codes when making decisions about how to install your new outlet. An experienced local electrician will be able to inform you of all codes and requirements in place at your home.
