"After 20 Years of having 4 Seasons install our entire system (AC,Furnace,Hot water heater) and 20 Years of twice a year maintenance at $89.95 per visit, this last AC tune up yesterday was a scam! I always defended 4 Seasons to all my neighbors and clients/friends when they would say how terrible 4 seasons was at telling them they needed unwarranted repairs or replacement. I never felt that 4 seasons was scamming me until yesterday. The tech told me that I needed 2 parts that were failing, but when I asked him to show me, he couldn't tell me why the parts were failing. He didn't know that I know my stuff and knew that the parts in question were just replaced and were just fine. So when I called the tech on it, he said that 4 seasons is asking their techs to find stuff wrong with their units to cover their as**es for the "No Breakdown Guarantee" that they offer customer for 1 year. So if something was wrong with their system, 4 seasons would not be liable since they "supposedly" found something wrong with the unit. They quote outrageous prices for the repairs to make you actually buy a new unit. This is not the ethical treatment I was used to for 20 Years. Very disappointed and now considering switching my loyalty to another company. Might consider staying with them if they extend my warranty as discussed privately."

We had a bunch of things that needed to be done including moving the riser for the incoming power line, replacing the old 100amp electric panel with a 200amp panel (line to the house was already 200amp-capable), installing new power outlets and a fan box on our deck, and pulling new wire in rooms to support a dual switch for separate light/fan functionality from the switch. They were very efficient, friendly, listened, provided suggestions, and got the job done right. I will absolutely be using Amp Electric & Power again when I need it!!!"

Generator installations FAQs

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
