The One Thing That Can Stall Your Generator Install

September 21, 2026

You’ve made the decision to get a whole-home Generac generator before winter hits Buffalo. Great idea, especially with the storms that Western New York experiences. However, a lot of homeowners miss a step and panic when they find out mid-quote that their electrical panel isn’t up for the challenge. 

Where to Begin When Thinking About A Whole Home Generator

A whole home generator does way more than sit in your yard waiting for a storm. When the power goes out, it has to pick up your entire house through a transfer switch wired into your electrical panel. And if that panel is old, undersized, or already maxed out, this stops being a simple install. Now it’s two jobs, first to fix the panel and then to put in the generator.

This takes many by surprise, and we understand why. Generator companies sell generators. Electricians handle panels. Nobody’s job is to connect the dots before you get a quote, so the panel problem tends to appear mid project and sometimes after you’ve already booked a delivery date.

Signs Your Panel Might Need Attention Prior to Installing A Generator

Warning signs can be spotted by anyone:

• Your panel is original to a home built before the 1990s
• You’ve had any work done recently that required “finding room” in the panel for a new circuit
• Breakers already trip somewhat regularly with normal day to day use
• You’ve never had the panel inspected and don’t know its rated capacity

These reasons don’t mean a generator install is out of the question. It just might require an electrical panel analysis beforehand.

How TRS Handles Generators and Electrical Panels Differently

Because TRS does both electrical work and generator installation, an Electrical Service Evaluation isn’t a separate errand you have to schedule with a different company. It’s the initial step and something we recommend after hearing about generator interest. 

Our $79 Electrical Service Evaluation includes:

1. Panel condition and capacity, including whether it can support a whole-home generator on top of your existing load
2. Wiring and connections, checking for wear or outdated materials that could complicate an install
3. Grounding and safety systems, confirming everything meets current code
4. A straight answer on whether you’re ready to move forward with a generator or need panel work first

If the panel can handle the capacity, we move straight into generator planning. If it doesn’t, you’re upgrading it with the same team that’s about to install your backup power, not coordinating between two companies and hoping they talk to each other. TRS comes out to homes across Western New York, from Buffalo and Cheektowaga to Hamburg, Clarence, and Grand Island, so wherever you are in WNY, we can get your evaluation on the calendar and on the right path to purchasing your generator.

Common Questions When Considering Whole Home Generators

Do I need to upgrade my electrical panel before installing a whole-home generator?

Maybe, maybe not, but you want to know before installation day, not on it. The generator ties into your electrical system through a transfer switch on your panel, and if that panel is old or already maxed out, it needs attention first. That’s the whole reason we do the $79 evaluation before anything else.

How do I know what size Generac Generator I need?

There are tons of things that factor into deciding what size generator you need for your home. Generac recommends getting an evaluation based on your home’s capacity, usage and outage possibilities before making a final decision on size. 

What do I actually get for the $79 evaluation?

With TRS’s Electrical Service Evaluation, we open up the panel and look at its condition and capacity. We ask questions like can it carry a whole-home generator on top of everything it’s already running? We check the wiring for wear or outdated materials, make sure the grounding and safety systems meet current code, and then tell you honestly if you’re ready for a generator, or the panel needs work first. 

What if my panel does need work, then what?

Depends on the house, but figure anywhere from a few days to a few weeks once you factor in scheduling and permits. Which is exactly why we’d rather tell you in September than have you find out in December. The evaluation gives you a real timeline up front, so nothing catches you off guard.
