FAQs

Frequently Asked Questions

What generator brands do you sell and service?

We are authorized dealers for Generac, Kohler, Cummins, and Briggs & Stratton generators. As a Generac Prestige Dealer, we have the highest level of certification and expertise for installation and service of all major generator brands.

How long does the generator installation process take?

Our turnkey installation process typically takes 2 to 4 weeks from initial consultation to final hookup, depending on permitting and site preparation requirements. Our factory-trained technicians handle all aspects including permits, site prep, and final inspections to minimize delays.

Do you offer ongoing generator maintenance plans or service contracts?

Yes. Our maintenance plans include annual check-ups, preventative maintenance, and remote monitoring services. Our service memberships provide priority scheduling, discounted repairs, and extended warranty coverage to keep your generator running at peak performance.

What kind of warranty protection is included with my new generator?

We stand by our generators with one of the best warranties in the industry. As an authorized dealer, all installations include manufacturer warranty coverage, and we offer extended warranty options for additional protection.

Why is planning ahead for a generator installation so important right now?

With increased demand and industry-wide supply chain challenges, waiting times have grown longer. Planning ahead gets you protected before the next major storm or outage. Don’t wait until it’s too late: schedule your consultation today.

What is a whole-home standby generator?

A standby generator sits outside your home, much like an air conditioning unit, and runs on your existing natural gas or propane supply, so it never needs refueling. When the utility fails it starts on its own and sends power straight to your electrical panel, with no extension cords. Depending on the unit, it can power part or all of your home, and it stops itself when utility power is back.

What does a Grasten installation include?

Once the contract is signed, our installation checklist runs to more than 100 items, including diagrams and drawings, building and fire code compliance, permits and approvals, site preparation, gas and electric utility coordination, fuel connections, transfer switch installation, inspections and generator start-up.

What affects the cost of a whole-home generator?

The size of your home, and whether you want the whole house powered or only the essentials. Installed prices run from $7,000 to $25,000+ across four size tiers, from essential circuits to the largest homes. Once the load is set, the project covers the generator, site preparation, the concrete pad, permits and the connection to your natural gas line. Your free estimate gives you the exact figure.

Can I get an estimate without a sales visit?

Yes. Our virtual site survey takes about 20 pictures and 20 minutes, at your convenience, with no salesperson visit needed to place your order. A follow-up call confirms the details, and qualified customers get special pricing.

Is maintenance required to keep my warranty valid?

Yes. Every manufacturer and dealer warranty requires yearly maintenance, and the 12-Year Power Plus Warranty requires that Grasten performs it, so the unit is looked after by the team that installed it.

Are there financing options?

Yes. Grasten offers financing through Synchrony Bank, with fast credit decisions and monthly payments, subject to credit approval.
