"10 yr old Generac GP6500E wouldn’t start. Called around and many want to upsell to permanent. Found Franks and what a delight. Honest, down to earth, affordable for senior. Showed up on time. Changed oil, spark plug. Pulled carburetor and found it dirty and fouled. Got used one from his shop(same day) and installed. Gen started right up on one or two pulls. Battery was dead but showed us how to replace. Highly recommend Frank’s Generator."

"Cale, Kyle, and crew are superb. They just installed my whole house generator and I can't overstate how personable, knowledgeable, and neat they were. Communication is excellent. I had to wait 5 months to receive my Generac because of a sever nationwide backlog, but Cale kept me informed all along. There is no other electric company I will ever use from now on. Paradise, you rock!"

"Installed the bathroom fan/light which wasn’t super easy, they had to crawl through insulation in the attic. Also changed out the broken switch on the outlet while they were there which was nice. Not terribly pricey"

Generator Install questions, answered by experts

Generally, you’ll want to keep between 60 and 70 feet between the generator and the transfer switch. There are a few reasons for this, including:

  • The distance reduces the noise coming from the generator into your home.

  • It increases efficiency because you won’t have a voltage drop from this short of a distance.

  • Prevents carbon monoxide poisoning: keep at least 15 feet between your generator and an open window. 

With proper maintenance, a whole-house generator can last between 20 and 40 years. The specific lifespan depends on how often and for how long the generator is used, and some models may have their life expectancy rated in hours of operation. To maximize its lifespan, expect to spend around $150 to $300 per year for annual maintenance checks from a qualified technician. During these checks, a technician will inspect the engine filter, starting mechanism, fuel, lubrication, and coolant levels. Consulting your installer and choosing a low-impact fuel like natural gas or diesel can also help ensure your generator lasts as long as possible.

If you’re wondering whether gas generators produce carbon monoxide, know that natural gas generators do not produce carbon monoxide if they are functioning properly, as natural gas burns cleanly. However, if the generator malfunctions and the gas does not burn completely, there is potential for carbon dioxide to be produced. To prevent malfunctions, it's crucial to perform regular maintenance, including running the generator weekly and scheduling professional inspections every 6 to 12 months. Also, be sure to test your carbon monoxide detectors regularly to ensure they function in the rare case of the generator producing carbon monoxide.

Homeowners can often access federal tax credits, such as the Investment Tax Credit (ITC), which covers a percentage of installation costs. Many states and utilities offer additional rebates, grants, or performance-based incentives. These programs can significantly lower your upfront investment. Check the Database of State Incentives for Renewables and Efficiency (DSIRE) or contact your local energy office for current offers.

Generators run on a variety of fuel types, ranging from natural gas to solar power. Keep in mind that fuel costs varying by type:

  • Natural gas: $2,000–$21,000 per year 

  • Liquid propane: $2,000–$21,000 per year

  • Diesel: $3,000–$20,000 per year

  • Gasoline: $500–$3,000 per year

  • Solar generator: $2,000–$25,000 per unit

  • Battery backup: $10,000–$25,000 per unit
