"FM Generator installed the whole house unit for much less than I thought it would be. They have been servicing it ever since. I am very pleased with the responsiveness of FM Genderator and the quality of their service. I live right on the ocean and the original generator died just before the warranty period. This is primarily due to the corrosive nature of the salt air. They reinstalled a new one quickly. I am very happy with their services, and have recommended them to others in my neighborhood."

"Galvin came for the installation of the Nest thermostat but started by first fixing my heating gas furnace before installing the thermostat. He is a great resource! I highly recommend him."

"Punctual and professional. All of the work was completed right on schedule. They upgraded my entire home and replaced electrical panel. Definitely hiring again; I have them scheduled to repair the sprinkler system electrical work and the fans in both my bathrooms. The cost was surprisingly affordable! I cannot recommend enough."

"I had no heat in the house. After plumber told me there’s electrical problem, I called a few electricians only to be told they could come ten days or two weeks out. Temps are dropping to low 40s and 30s. Desperately I gave Biondich Electric a call and spoke to Mat. As soon as he heard no heat, he rescheduled his other appointments and came to help me in the same afternoon. He was very thorough and thoughtful, even took extra time to explain everything to a novice like me. He got the heat back on in a few hours after rerouting wires and Installing things for extra safety. He even came by once again the next morning to help me diagnose one other plumbing issue. Mat is very professional, knowledgeable and courteous. His rate is reasonable. I will definitely call him when I have electrical problems in the future and will recommend him to my friends on the cape. Thank you, Mat!"

"Nick was very quick and professional. Is always a great guy to deal with. We have had him come to work on a couple projects for us so far as we upgrade and finish construction. His pricing is a little high but you really get excellent work. He has done a lot of work for people I know as well and Ive passed his business cards to 2 people I know who are seeking help. I have received lots of compliments on what he’s done here."

Generator Install questions, answered by experts

To power a central air system during a power outage, the whole-house generator will need to be at least 5,000 watts, and this number will significantly increase for larger units. Check the specific wattage requirements of your AC unit to choose the right generator size. Consider consulting a generator installer to ensure your whole-house generator meets your electrical load needs.

You can determine what size generator you need for a transfer switch by matching the switch to the largest outlet on your generator. Larger generators can power up to 10 circuits, while most 5,000-watt generators can provide power to six circuits. So, if your generator’s largest outlet is 30 amps, you’ll need a 30-amp transfer switch.

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. 

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

Energy output depends on turbine size, average wind speed at your site, and system efficiency. A 5 kW turbine in a good wind location can generate 8,000 to 12,000 kilowatt-hours per year, which may cover a large portion of an average home’s needs. Accurate output estimates require a professional wind assessment and a review of your household’s energy usage patterns.
