Frequently Asked Questions

Common Generator Questions

How much does a whole-home generator cost to install?

Installed cost typically runs from $8,000 to $18,000 depending on generator size, fuel type, distance from your electrical panel, and whether a service upgrade is needed. We provide a firm quote at no charge after a home assessment.

Does natural gas or propane work better?

Natural gas is more convenient because it never runs out during an extended outage as long as the gas line is functioning. Propane requires refilling an on-site tank, but it works in rural areas without natural gas service. We install both.

How long does the installation take?

Typical installation is one to two days on-site once permits are approved. Permit approval time varies by municipality. From first call to running generator is generally three to six weeks.

Do you install the automatic transfer switch too?

Yes. The transfer switch is included in every installation. It is what allows the generator to automatically take over when your utility power fails, without any action from you.

Do you service generators after installation?

Yes. We offer annual maintenance plans and repair service for generators we install. Regular maintenance is important for warranty coverage and reliability.

What areas of Michigan do you serve for residential generators?

We serve homeowners across mid-Michigan, southeast Michigan, and west Michigan. This includes Lansing, Charlotte, Grand Ledge, Eaton Rapids, Jackson, Ann Arbor, Brighton, Howell, Wixom, and the Grand Rapids area. Contact us to confirm service in your specific location.

Do generators qualify for any tax credits or incentives?

Standard residential standby generators do not currently qualify for federal tax credits. However, if you use your generator for medical equipment, some medical expense deductions may apply. Check with your tax advisor.
