GEM was great! From customer service to Sales Rep to technicians/installers they were professionally friendly, knowledgeable, and on time every time. A bit pricey, but for the piece of mind, I'm very happy with their service. I will definitely keep using them in future if needed. Update: I had an error code on the NEW unit that GEM installed, that GEM could not fix after calling them for a full year. I called another company that took them 20-30 minutes to fix. I WILL NEVER USE GEM AGAIN!!!

Signs It’s Time to Install a New Generator for Your Home

Generators are built to last, but they don’t last forever.

If your current system is showing its age or struggling to keep up with your home’s needs, upgrading to a new generator can restore reliability and peace of mind.

As generators age, performance and efficiency can decline, even with regular maintenance. Newer models offer improved reliability, quieter operation, and better fuel efficiency.

If your generator hesitates to start, shuts down unexpectedly, or doesn’t power your home consistently, it may no longer be dependable. These issues often signal internal wear that replacement can solve more effectively than repeated repairs.

Needing repairs more often is a common sign that your generator is nearing the end of its lifespan. Investing in a new system can be more cost-effective than continuing to fix an aging unit.

Home additions, new HVAC systems, or added appliances can push an older generator beyond its capacity. A new generator ensures your home has the right amount of backup power for how you live today.

Benefits of Installing a New Generator

A new generator helps you feel confident in your home’s electrical system at all times.

With today’s advanced technology, installing a new generator helps protect your comfort, safety, and daily routine when outages strike. Some of the benefits homeowners notice include:

New generators are designed to start quickly and run consistently during outages. That reliability means your home stays powered without the uncertainty of aging equipment.

Modern generators are more fuel-efficient and better matched to today’s homes. They deliver dependable power while using energy more wisely, helping reduce long-term operating costs.

Newer models run noticeably quieter and include advanced features like automatic load management and system monitoring. These upgrades make backup power more seamless and less disruptive.

Frequently Asked Questions About Generator Installation

What is the difference between portable and standby generators?

Portable generators are smaller units that must be manually set up and powered by gasoline or another type of fuel during an outage. Standby generators are permanently installed and automatically turn on when power is lost, providing seamless backup for your home. Many modern generators run on natural gas, providing a steady fuel supply without the need for refueling.

Is financing available for generator installation?

Yes, financing options are available to help make installation more manageable. Plans can vary based on your needs and project scope. GEM will walk you through available options and help you choose a solution that fits your budget.

What type of generator is best for my home?

The right generator depends on your home’s size, electrical demand, and the systems you want to keep running during an outage. Sizing the unit correctly ensures reliable performance without unnecessary cost. GEM evaluates your needs and recommends a system that fits your home.

Do I need permits for generator installation?

Yes, generator installation typically requires permits and inspections based on local regulations. These steps ensure the system is installed safely and meets code requirements. GEM handles permitting, compliance, and coordination with your utility company.

How long does generator installation take?

Most generator installations are completed in one to two days after permits and approvals are secured. The timeline can vary based on site conditions and system complexity. GEM manages the process and keeps you informed throughout.
