A whole-home generator provides reliable backup power when you need it most, keeping your home running during outages caused by storms, grid failures, or unexpected emergencies. Unlike portable generators, a standby generator automatically turns on when power is lost, ensuring that essential systems such as heating, cooling, refrigeration, and lighting continue to operate without interruption. Professional installation ensures your generator is properly sized, safely connected, and ready to deliver dependable performance whenever you need it.

At Paul Macrina Electrical, we specialize in whole-home generator services including installation, repair, and maintenance. Our licensed electricians will help you choose the right generator for your home, connect it seamlessly to your electrical system, and provide ongoing service to keep it in peak condition. Whether you’re installing a new standby generator or need expert care for an existing unit, you can trust our team for reliable whole-home generator services near you.

How Do Whole-Home Generators Work?

A whole-home generator is connected to the electrical wiring in your home and it is designed to detect any interruptions in your service. When an interruption occurs, the generator automatically switches on and begins powering your home. Whole-home generators are standalone power sources that run off of the natural gas or propane lines in your home, so you do not need to worry about keeping it refueled.

There are portable generators which can be useful in the event of a blackout, but they do not generate the same level of power as whole-home generators and will only be able to provide electricity to a select few appliances or systems in your home. Portable generators also require refueling from an outside source, so you must have backup fuel stored in your shed or garage.

Benefits Of Whole-Home Generators

There are a number of reasons why installing a whole-home generator can be beneficial to you and your family. If you are considering sticking with a portable generator instead, check out these major reasons why you may want to go with the whole-home option:

Power What You Need

A whole-home generator can provide power to, well, your whole home. Portable generators are limited in their capabilities, meaning you may need to have more than one to provide you with the electricity you need. Not only that, whole-home generators can be customized to only provide power to certain key areas of the house if that is what you prefer, so you do not have to worry about the cost of powering every square inch of your home if you do not want to.

No Need To Refuel

Your whole-home generator will be directly connected to the gas or propane lines in your home, meaning you do not have to worry about where to store your generator fuel, or where you are going to get more once your backups run out. Whole-home generators can generally run for as long they need to until power is restored.

Safer

A poorly placed portable generator can run the risk of filling your home with deadly carbon monoxide gases. Whole-home generators are installed in a safe area, and are mostly hands-free, eliminating most of the potential dangers that come with a portable generator.

Quieter

Portable generators are also quite loud, and while whole-home generators are not silent by any means, they are a lot quieter and therefore less of a disturbance to you and your neighbors. This may seem like a small issue, but if a blackout lasts several days, an overly loud generator can become another source of stress during an already tense time.

Hands-Free Power

If you are on vacation to escape the frigid New England winter and a power outage occurs, you will not be there to make sure your food does not spoil, your pipes do not freeze, and your security system does not go down. With a whole-home generator, you do not have to be there to maintain power in your home. It simply switches on automatically, your fridge stays cold, your pipes stay warm, your security system stays on, and you stay calm, cool, and collected.

How Do I Know Which Type Of Generator Is Best For Me?

Choosing the proper size, capacity, and model generator for your home is not too complicated, but it does require careful consideration, and possibly the help of a qualified professional. When you enlist the help of Paul Macrina Electrical Contracting, Inc. whole-home generator services, we will work with you to assess your home’s power needs, as well as what you are looking for in a backup generator, and make a recommendation for the unit best suited for you and your family.

FAQs

Frequently Asked Questions

(508) 359-7954Book Online

How long does it take for a whole-home generator to turn on during a power outage?

A standby generator typically starts automatically within seconds of detecting a power outage. The automatic transfer switch then transfers your home’s electrical load to the generator once it’s ready. The exact timing depends on the generator model and system configuration.

What size whole-home generator does my Medfield home need?

The right generator size depends on your home’s electrical demands and which appliances and systems you want to power during an outage. Our team at Paul Macrina Electrical evaluates your heating and cooling equipment, refrigeration, lighting, and other electrical loads to help determine an appropriate generator capacity.

How often should my standby generator be serviced?

Maintenance schedules vary by manufacturer, model, and operating hours. Most standby generators require periodic inspections, oil and filter changes, battery checks, and operational testing. Our team can help you determine the appropriate maintenance schedule for your equipment.

Will my whole-home generator run if I'm away during a storm?

A properly functioning automatic standby generator is designed to detect an outage and start without someone being home. Once the generator is ready, its transfer switch supplies power to the connected circuits, helping keep selected household systems operating while you’re away.

Does Paul Macrina Electrical repair existing whole-home generators?

Our team provides whole-home generator repair and maintenance services in addition to new installations. We can evaluate an existing generator, investigate starting or operating problems, and determine the appropriate next steps based on the equipment’s condition and service requirements.

The electrician from Macrina Electric Company who came to replace and install a new bathroom fixture was very impressive. He knew exactly what he was doing and kept me informed during the installation of a new bathroom overhead light that had many different light settings. He advised me on the "light" setting that was perfect for our bathroom. He also kept me informed about when he would arrive.Thank You Macrina…

Someone answered the phone when we called! They came out the same day and were professional and thorough.

We had an issue with our circuit breaker - and the technician did a great job identifying the issue (cut wire from lawn service) that we would not have been able to find ourselves. Scheduling, communication from the office, and a friendly electrician that explained the issue / fix was great. We would recommend them and engage them again for future work.
