At Generator Supercenter, we are committed to securing your home and peace of mind with back up power solutions. When bad weather hits or an electrical circuit malfunctions, a power outage is likely. When that happens, you can recover quickly if you own a reliable home backup generator. Once your generator is installed, you’ll need reliable technicians available 24/7 and capable of providing quick services. Generator Supercenter of New Hampshire provides experienced technicians for generator installation, repair, and maintenance. Benefits of working with our team: Full-service – Whether you need a new generator, or your current one is malfunctioning, we won’t leave until your generator is up and running as it should be. Convenience – If something goes wrong with your generator, you don’t have to worry about going out to buy a new one or to replace parts. We will come to your home or business and take care of it for you. Free on-site estimate – When you call us, you’re not committed to a service—our estimates are free, so you can meet with a member of our team to learn about your options with no strings attached! Unfortunately we do not do anything with portable generators or any brands not manufactured by Generac. We are also not a parts distributor.

Generator Install questions, answered by experts

A 1,500 square foot home will likely need a 15kW to 20kW generator. When deciding on whole-house generator size, add up the total wattage of the devices that you’d like to continue running during a power outage. That way, you can ensure you purchase a generator that can power your necessary appliances or medical equipment during an electrical emergency.

Yes, natural gas generators can work without electricity. Natural gas generators are a common type of backup or whole-house generator that operates when the electrical grid isn’t working. The trick is using a transfer switch (which usually needs to be installed with the generator) that safely switches the home electrical system from the power grid to generator power when needed.

Carbon monoxide emissions aren’t only dangerous to human life, but they also harm our planet. While natural gas generators emit lower levels of CO than other fuel sources, there are still ways to reduce emission levels. For example, shop around for an eco-friendly generator that complies with current emission standards. Also, make sure your generator is serviced regularly to avoid CO buildup. 

Generator size requirements vary wildly among properties, but typical generator sizes are listed below based on home square footage:

  • 1,000 sq ft: 6–9 kW

  • 1,500 sq ft: 7–10 kW

  • 2,000 sq ft: 10–14kW

  • 2,500 sq ft: 12–16kW

  • 3,000 sq ft: 16–20kW+

Unfortunately, home square footage isn’t always a good indicator of generator size requirements. Instead, you should call in a professional to discuss which items in your home you’d like to run via your generator. They can calculate peak and average consumption for those items and then size your generator appropriately for optimal performance.

An undersized whole-house generator has the potential to overheat and shut down when you try to run a central AC system. This scenario can not only damage the whole-house generator, but can also trip your home’s breakers or cause electrical damage. To avoid this situation, hire a local generator installer to correctly size your whole-house generator.
