Home Generator Installation & Replacement near Oakbrook Terrace, IL
Whole Home Backup Generators
When the power goes out, you want your home to keep running. Heat, sump pumps, fridge, internet, everything! At Hey Guy, we design and install whole home generators sized for your house, your panel, and your lifestyle. From load calculations and permits, to concrete pad, gas/electrical hookups, and start-up, our licensed electricians handle the entire whole home generator installation process.
Why Add a Whole House Generator?
A professionally installed whole house generator (a.k.a. standby or backup generator) automatically powers your home within seconds of an outage. There’s no extension cords or portable units. Some of the benefits of these generators include:
Automatic protection: Transfer switch detects outages and restores power seamlessly.
Protects what matters: Sump pumps, medical equipment, security, HVAC, and refrigeration keep running smoothly.
Property value & peace of mind: A permanent, code-compliant system buyers recognize and love.
Fuel flexibility: Natural gas or propane powered options offer extended runtime and low maintenance.
Generator Types & Smart Options
We specialize in standby generator installations for single-family homes and light commercial spaces. Some of the most common types of services include:
- Air-cooled standby generators (natural gas or propane): Cost-effective, great for most residences.
Liquid-cooled standby generators: Higher capacity for larger homes, small businesses, or heavy loads.
Smart transfer switches & load management: Prioritize critical circuits (furnace/boiler, sump, fridge, Wi-Fi, well, garage door, selected outlets) to fit your budget and service size.

Replacements: When It's Time to Upgrade
If your current unit is 10 to 15+ years old, struggles during peak loads, or parts have become scarce, a generator replacement may be your best option. A newer generator can not only save money in the long run with improved efficiency, but they run quieter, offer smart options like remote monitoring, and provide better load management. We’ll also try to reuse compliant infrastructure where possible to reduce the replacement cost.
FAQs
Do I need a home backup generator?
If power outages risk flooding (sump pump issues), health/safety issues (medical devices, heating), or major disruptions (work-from-home, refrigeration, etc.), a standby generator is a smart, long-term solution for uninterrupted power.
Are backup generators noisy?
Modern standby units are quieter than older models. They usually operate between 55 to 70 dB at 23 feet. This is roughly the level of a typical conversation to a vacuum cleaner running. We make sure to place the unit not only to meet code clearances, but to minimize sound disturbance for you and your neighbors.
How big of a generator do I need?
Every home may be different. During the investigation phase we calculate starting and running loads for HVAC, sump, fridge, lighting, and other major energy sources your home uses. Most homes land somewhere between 10 – 24 kW, depending on furnace/AC tonnage and other priorities during an outage.
How long does installation take?
Typical installs run 1 to 2 days on site after permits and gas utility coordination. The entire job is often completed within a few weeks from start to finish.
Can Hey Guy help with electrical panel upgrades?
Yes. Many older homes benefit from an upgraded panel or service upgrade when adding a standby generator. We’ll advise what is best during our initial visit.
