"The crew showed up on time and did a great job. They dug a trench from my house to my pool to install a new circuit to the pump. They installed a GFCI waterproof electrical box for the pump. Afterwards, they dug a trench and added the grounding ring around the pool. Received the inspection the following day and the crew came back to fill the trenches and to throw down grass seed. The crew and office staff were very professional and knowledgeable. I would definitely recommend them and I will personally be hiring them again for more work around my house."

"The whole process of quoting, sales presentation, finance arrangement, installation was simple, timely, professional, complete and painless. The price was very competitive, the installation was smooth and prompt, and the end product is thing of beauty. This review is from a homeowner who has had a couple of terrible furnace experiences in the past decade."

Generator Install questions, answered by experts

Generators are usually sized by running watts and starting watts. Ideally, you’ll want a generator that can offer both the necessary running watts and starting watts for everything you need to power without going beyond 90% of its capacity. Calculate your home’s electrical load based on the breakers in your home or adding up the appliance and lighting needs of connected rooms.

Costs range from $500 to $2,500, depending on generator type and installation complexity.

If you have a transfer switch properly installed, the generator and main electrical power cannot feed the system at the same time. However, you should still shut off the power at your main circuit breaker panel before activating the generator. If you do that, you’ll simply need to shut off the generator and reset your circuit breaker once the local power comes back on.

You can determine what size generator you need by listing the various appliances it will power during an outage. Write down the start-up watt usage, and then add them all together. 

A 7,500-watt generator will run your refrigerator, freezer, well pump, and lighting circuits without a problem. However, you’ll need an extra 3,000 to 4,500 watts to run your water heater and another 5,000 to 25,000 watts to run your electric furnace. In these instances, a whole-home generator is your best bet for running your critical equipment.

While the rating will tell you how many watts the refrigerator needs at the peak of its cycle, it requires additional wattage to start. At the bare minimum, you’ll need a 1,500-watt generator to get the fridge up and running after a blackout. A 2,000-watt generator should be sufficient for most home refrigerators.
