Michigan Critical Power is a factory-trained Generac dealer and service center based in Byron Center. We size, install, maintain, and repair Generac Guardian Series home standby generators across Grand Rapids, Holland, Kalamazoo, and all of West Michigan.
Generac was the first company to bring affordable, automatic backup power to homes, and it remains the most widely installed home standby brand in the country.
For West Michigan homeowners, that market position translates into three practical advantages: parts are readily available so repairs rarely stall waiting on shipments, the technology is well-proven across millions of installations, and the price-to-coverage ratio is hard to beat for whole-home protection.
Generac isn't automatically the right answer for every house — we also install Kohler, Briggs & Stratton, Cummins, and BlueStar, and we'll tell you when one of those is a better fit. But for most homes in our service area, a Guardian Series unit delivers the coverage people want at the price they expected.
Being an authorized dealer matters more than it sounds. It means warranty repairs are handled in-house rather than referred out, our technicians are factory-trained on current Generac controllers and diagnostics, and we can pull genuine parts directly instead of sourcing aftermarket substitutes.
A multilingual LCD display lets you monitor battery status and track maintenance intervals right at the unit — so problems surface before an outage, not during one.
Check your generator's status from anywhere using a phone, tablet, or computer. We set this up and walk you through it before we leave your driveway.
A RhinoCoat powder-coated corrosion-resistant aluminum enclosure — which matters more than most homeowners realize given Michigan road salt and lake-effect humidity.
Guardian units run on either fuel. Natural gas connects to your existing utility supply; propane works where gas lines don't reach. We size the connection during your assessment.
Guardian Series generators are made in the USA and backed by Generac's 5-Year Limited Warranty. Documented annual service keeps that coverage intact — we track your history and remind you.
The Guardian Series spans 10 kW to 26 kW, which covers everything from essential circuits to full whole-home protection. Here's how that maps to real West Michigan homes.
| Size | Typical Fit | What It Realistically Powers |
|---|---|---|
| 10–14 kW | Smaller homes, condos, or essential-circuit setups | Furnace, refrigerator, sump pump, well pump, lights, and outlets — the things you can't do without. Usually not central A/C. |
| 18–22 kW | Most homes between roughly 1,500 and 3,000 sq ft | Whole-home coverage for the majority of our customers, including central air, in a typical single-HVAC-zone house. |
| 26 kW | Larger homes, multiple HVAC zones, heavy loads | The largest air-cooled generator on the market — whole-house coverage where a 22 kW would be working at its ceiling. |
| 30 kW and above | Estates, farms, and commercial properties | Liquid-cooled systems. We spec these case by case — contact us to discuss your load requirements. |
This table is a starting point, not a recommendation. Square footage alone is a poor sizing method — insulation, HVAC type, well pumps, and electric appliances all change the math. We calculate your actual load on site, at no charge.
Get My Load Calculated FreeOne company for the entire life of your Generac — not a seller who disappears after the install.
Free load assessment, model selection, permits, utility coordination, concrete pad, automatic transfer switch, licensed gas connection, and full load testing. Most residential installs finish in one day.
Oil and filter change, spark plug inspection, battery and transfer switch verification, and a written condition report — the documentation Generac's warranty requires.
As an authorized dealer we perform in-warranty Generac repairs directly. No being handed off to a third party and waiting weeks for a resolution.
Error codes, won't-start conditions, low output, transfer switch faults, control board issues. Our trucks carry the most common Generac parts, so most calls are resolved on the first visit.
Bought your Generac elsewhere, or inherited one with the house? We service it the same as our own installs — no penalty, no runaround.

Yes. We're an authorized Generac dealer and service center with factory-trained technicians, serving West Michigan from Byron Center since 2004. That covers sales, sizing, installation, warranty repairs, annual maintenance, and 24/7 emergency service.
Most West Michigan homes of 1,500–3,000 sq ft are well covered by an 18–22 kW Guardian, with 26 kW for larger homes or multiple HVAC zones. But square footage is a rough proxy at best — well pumps, electric appliances, and HVAC type all change the answer. We calculate your actual load during a free on-site assessment.
A complete Generac installation for a typical West Michigan home generally runs $7,000 to $18,000 — including the unit, automatic transfer switch, electrical work, gas or propane connection, concrete pad, permits, and labor. Size, fuel setup, gas line distance, and panel condition determine where you land in that range. Every quote we give is written and flat-rate.
Yes — maintenance, diagnostics, warranty repairs, and emergency service, regardless of who installed the unit. Plenty of our maintenance customers bought their generator elsewhere or inherited it with the house.
Generac's air-cooled home standby units carry a 5-year limited warranty. Documented annual maintenance is generally required to keep that coverage valid — the most common reason we see warranty claims denied is a missing service record. We track your history and call you when service is due, so it doesn't fall through the cracks.
Yes — Generac's Mobile Link lets you check status, run history, and alerts from a phone, tablet, or computer. We set it up and walk you through it during your install walkthrough, so it's working before we leave rather than sitting in a box.
