Here’s How to Tell if You Need a New Generator

If your system is showing signs of wear or inconsistent performance, it may be time to consider a replacement.

If your generator needs regular repairs or service calls, it may be reaching the end of its lifespan. Ongoing issues can quickly add up, making replacement the more reliable and cost-effective option.

A standby generator should turn on automatically when the power goes out. If it hesitates, struggles, or fails to start at all, your home could be left unprotected during an outage.

If lights flicker, appliances struggle, or your system can’t power essential equipment, your generator may be undersized or losing capacity. A replacement ensures your home gets the dependable coverage it needs.

Outdoor generators are exposed to the elements year-round. Significant rust, corrosion, or physical damage can impact performance and signal it’s time for an upgrade.

All of our electrical outlets needed attention, the ground fault circuits seemed iffy, and labeling on the circuit panel itself was questionable. Angelo was professional, knowledgeable, and efficient. He kept me updated on what he was finding and the repairs he was making as he went from room to room. I will sleep well tonight knowing that our electrical system is now safe and reliable – thank you Angelo!

We had some leaking water in the basement. It was one of our toilets and a water pipe. The problem was uncovered and resolved quickly. They had everything they needed to fix both problems and cleaned up after themselves.

GEM Will Help You Find the Right Generator For Your Home

Different generators come with different capacities and features, and choosing the right one can feel overwhelming.

Think about which appliances and systems you want to run during an outage. A professional load calculation ensures your generator can handle your essential equipment without overloading.

Generators can run on natural gas, propane, or diesel. We’ll review your home’s existing fuel sources to determine the most efficient and practical option.

Standby generators turn on automatically when the power goes out, offering seamless protection. This is especially important for homes with medical devices or critical systems.

Modern generators are designed to run more quietly, but placement still matters. We’ll help determine the ideal location that meets local codes and keeps noise to a minimum.

Frequently Asked Questions About Generator Replacement

How long does a generator replacement take?

Most generator replacements can be completed in a day, depending on the complexity of the installation and site conditions. GEM will provide a clear timeline during your in-home assessment so you know exactly what to expect.

How do I know what size generator I need?

Generator sizing depends on your home’s square footage and the number of systems and appliances you want powered during an outage. Our licensed electricians perform a detailed load calculation to ensure your new system can handle your essential needs without overloading.
