Home Generator Installation & Repair in Champaign, IL

Whole-Home or Select-Circuit? We'll Help You Decide.

Not every home needs the same backup. Some homeowners want everything covered, no exceptions. Others just need the furnace, the fridge, and a few outlets to keep running. Both are real options, and the right one depends on your home and your budget.

Whole-Home Backup

Every circuit stays on, from your HVAC to your kitchen. Nothing shuts off, nothing to prioritize. The power outage barely registers.

Select-Circuit Backup

A smaller system wired to what matters most. Your furnace, fridge, and sump pump keep running. A smart choice if you only need the essentials covered

How a Home Standby Generator Works

No manual start, no fuel runs, no waiting around. Once it’s installed, the system handles the entire outage on its own from start to finish.

01

Power Goes Out

Your home loses utility power.

02

The Generator Detects It

It kicks on automatically within seconds of sensing the outage. No one has to start it or flip a switch.

03

Your Home Switches Over

The system takes over and keeps running for as long as the outage lasts, whether that's a few hours or a few weeks.

04

Utility Power Returns

The generator shuts itself off automatically once power is back.

What We Look At Before Recommending a System

Generators come in a range of sizes, and the right one depends on more than square footage. Before we recommend a system, we look at a few key factors. That’s how you get a generator sized for your home, not a generic recommendation.

We walk through a full load calculation with you, so the size we recommend actually fits your home.

Signs Your GeneratorNeeds Attention

Generators are built to run for years, but they’ll show warning signs before something fails. Catching these early is the difference between a quick service call and a generator that doesn’t start when you need it most.

If something feels off, don’t wait for an outage to find out.

C-U Trade Services recently installed a water softener in our home, and this has made a significant difference in our water quality, with positive implications for our dishwasher, washing machine, showering, and more! Jeremy clearly explained why our home would benefit from a softener, and his installation work was outstanding. Highly recommended. I also want to note the wonderful work and fair prices I've experienced over the years for HVAC and electrical work from C-U Trade Services.

Called CU Under Construction for a leak in my crawlspace. Curtis and Mitchell came within two hours of calling and completed the service in less than an hour. Another plumbing company looked at it before CU Under Construction and said they did not have the capacity to fix the problem. I will continue to use CU Under Construction for whatever problem I have at my home in the future. The price for repairing my leak was extraordinarily reasonable, and I was happy to pay every penny. Thank you see CU Under Construction.
Response from the owner:Thank you so much for your kind words! We're thrilled to hear that Curtis and Mitchell were able to promptly address your leak issue and provide exceptional service. We're dedicated to delivering quality work at reasonable prices, and we're grateful for the opportunity to help! Looking forward to working with you again in the future!
