"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."

"I have found my forever electricians (at least while I live in the New Haven area)! From start to finish my experience with Power Forward was an absolute pleasure. Company owner, Ian, was responsive, punctual, and incredibly informative when it came to walking me through the details of the scope of work I was requesting, and was thoroughly transparent and fairly priced when it came to his estimate. Once we accepted the quote, scheduling with Morgan was easy and efficient, and Chris arrived onsite within a day of me accepting the estimate. Chris was a consummate professional, a super clean worker when it came to caring for our house and the cleanliness of his cable paths, and was truly dedicated to doing the job â the right wayâ not just the easy and cheap way. He took his time and planned his cable runs and circuiting carefully to ensure both minimal cutting into our walls and convenient receptacle placement. Once he was finished, he took care to clean every area heâ d worked in and probably left some of the rooms cleaner than when he arrived! I would recommend Ian and Power Forward to anyone who appreciates work that is done with care, safe, and efficient. I think you get what you pay for when it comes to hiring trade professionals, and electricity is not something you want to cut corners with: hire Ian and his team, and have it done right and safe the first time."

Generator Install FAQs, answered by experts

Costs depend on generator type, labor, and additional wiring or transfer switch requirements.

Setting up utilities on a vacant property usually takes at least a few months, or between 6 weeks to 16 weeks. This process requires working with the local planning and zoning department, hiring a building contractor or engineer to design the utility layout, securing permits, laying the lines, and connecting the utilities.

The cost to install a whole-house generator averages $5,200, with a typical price range of $1,500 to $8,900. However, total costs can vary from $400 for a small portable unit to over $18,000 for a large-capacity system. The most significant cost factor is the generator's size and capacity, but other variables include the brand, fuel type, and labor for assembly and installation.

Generator costs can be broken down by type:

  • Portable or Emergency Backup Generators (1kW–7.5kW): $500 to $2,000

  • Partial-Home Generators (9kW–20kW): $2,000 to $6,500

  • Whole-House Generators (22kW–48kW): $5,000 to $18,000

To avoid paying for more power than you need, consider hiring an electrician to calculate the electrical load for your essential appliances. It is also recommended to get at least three quotes to find the best deal for your specific needs and budget.

Sizing a generator is a careful process that requires calculating the electrical load of your entire house. You have to take into account every device you want to use and their wattage requirements, plus the wattage needed to start them, and look for a generator that can safely run all that at around 80% capacity.

In more practical terms, a small home can run on a 10,000-watt generator (and if you only want to power a few key appliances, much less than that). A mid-sized home may need something between 15,000 and 22,000 watts. Larger homes require 25,000 watts or more. 

To reduce AC startup power for a whole-house generator, install a soft start kit or hard start capacitor, which lowers the initial surge by gradually ramping up the compressor. Using a smart load manager can also help by staggering startup loads, preventing a system overload and future costly repairs.
