The Benefits of a Home Generator

Since we've been in the industry for 40+ years, Energy Shield is New Hampshire's trusted generator installer. But why is a home generator so beneficial to have?

Keeps The Power Going

When the electricity goes out, a generator will quickly restore all of your house’s conveniences and safety measures. You’ll appreciate how quickly the TV, computer, water heater, security system, and more will be restored. 

There are a number of reasons it might be important to you to keep the power going in an outage like if you work from home, live in an extreme climate, keep a lot of food chilled, and more.

Prevents Water Damage

Every homeowner knows the irreversible damage water can do. That’s why it’s important to take every precaution in preventing water damage in the home.

Long-lasting power outages can wreak serious havoc on a home. Winter storms often cause intense power outages that freeze and crack pipes, causing leaking and floods. Any sump pumps or dehumidifiers you have in your home won’t go down if you have a generator to back you up.

Keeps Food Fresh

In the case of a long-term power outage, your chilled food can easily go bad. With a generator, you can avoid throwing away food and wasting money. You can also keep eating refrigerated or frozen foods during the blackout. Bring on the fresh produce! In addition, you’ll get an increased variety of foods thanks to being able to cook with your electrical kitchen appliances.

Keeps You Safe

Backup generators safeguard your loved ones by reducing crime during prolonged blackouts. If you have a home security system, it can remain running.

Since home generators use propane or natural gas and are outside, they are safer than gasoline-powered generators. Home generators have a significantly lower risk of carbon monoxide toxicity than portable generators.

Generators shield your home’s electrical system from voltage changes and power surges when the electricity does come back on. In doing so, it prevents fires or shocks.

FAQs About Home Generator Installation

The size generator you choose depends on what you want to power, whether it’s your entire home or only essential appliances like the refrigerator, sump pump, heating system, etc. 

Generator placement is important in determining the required work to install the system. Because of that, the best place for your generator is where the gas and electric meters are both reasonably close by. 

Typically, the generator needs to sit at least 18 inches from the side of your house and at least 5 feet from the lot line. Additionally, the generator must be 5 feet away from any window or entrance in accordance with manufacturer recommendations and regional regulations.

On average, consumers spend around $9,000 on a home generator. However, depending on your power needs, you could end up spending from $2,000 to $20K.

At Energy Shield, we’ll always work with you to come up with the solution that fits your needs and your budget.
