"While the service was completed in a timely manner, the cost of installation and services was not near the original estimate. In addition, it appears that the installer took advantage of my wife's naivete and sold her additional products that were not necessary. While she is an adult and capable of making decisions, her lack of knowledge about electrical matters led her to purchase electrical outlets for 3 bathrooms costing a total of $225 that were not needed. In addition, the price for a simple bath fan was extremely high ($250) and had we known in advance the price would have been that high, we would have purchased our own fan at a significant savings from Home Depot or Lowe's (the same model sells at those stores for approximately $75)."

"Gammon's attempted to install a new propane boiler for me. The job took nearly a year after several complaints about boiler malfunctioning/shutting down (in the middle of winter), over heating, water leaks and even a significant propane leak, costing me hundreds of dollars in leaking propane! They signed off on the job with several connections leaking propane. They left many things undone and not to code. I had to get the Department of Professional and Occupational Regulation Maine Fuel Board involved with a inspection (which was very helpful) for them to come back out and address the issues. The owner never answered any of my e-mails/calls about these issues (even the concern about LEAKING PROPANE). I still have a thermostat that isn't working correctly and have just had to leave it off. I placed a complaint with the Maine Attorney General and yet have come to a resolution. I will say that the office staff was very helpful and pleasant. Read less"

Installing a whole-house generator costs about $5,000 on average. Prices range from $1,550 to $8,500, depending on size, brand, fuel type, and assembly. The size of your whole-house generator is the most significant cost factor, with large homes with high energy demands costing the most to power. Types of whole-home generators include:
Portable generators with 1kW–7.5kW capacity: $500–$2,000
Partial generators with 9kW–20kW capacity: $2,000–$6,300
Whole-house generators with 22kW–48kW: $5,000–$18,000
When maintained properly, a whole-house generator can last up to 20 years. Costs to maintain and repair generators vary by location and type of generator, but you can expect to pay about $150 to $300 per year for annual generator maintenance checks. An experienced generator service technician will inspect your generator’s engine filter, starting mechanism, fuel, lubrication, and coolant levels to keep your generator in good working condition for as long as possible.
When choosing the right size generator for your needs, consider a few items to help calculate the wattage you’ll need. Start by determining which household items and appliances you want to power, and then add the wattages together. Check out the wattage of these essential appliances:
Refrigerator: 600 watts
Large dehumidifier: 700 watts
Large window air conditioner: 1,400 watts
Water heater: 3,000 watts
Running home appliances like these requires a partial or whole-house generator. A portable generator may be enough to power your home if you only plan to keep a refrigerator and freezer running.
Here’s what you can run with different wattages and types of generators:
Portable generator:
2,000 watts can handle a large appliance like a freezer or refrigerator, plus a few smaller items like phones or computer chargers.
4,000 watts will keep two large appliances operating and a few smaller devices.
8,000 watts should power most essential appliances and other devices, including a sump pump, well pump, or your dishwasher.
Partial to whole-house generator:
20,000 watts and above will make it seem like your home’s power is still on.
The value of installing a whole-house generator is that your home has guaranteed power, even if the power grid in your area is down. Whether a whole-house generator is worth installing in your home depends on how often you use it, your home’s location, and your lifestyle. For example, installing a whole-house generator is likely worth it if you:
Experience frequent or prolonged power outages
Work from home
Store a lot of cold food
Have a sump pump
Have a pump for well water
Use electronic medical devices
Live in a climate requiring heating or cooling
