"The team from Eanes was fantastic.....especially Chris Louya, Tito and David. They all did a great job, listened to my concerns, were thorough and spend 14 hrs. here installing the unit without any of them complaining. They were always hardworking and pleasant. The HVAC unit is working great and the best unit I've had in 45 yrs.!!"

Hey iโ€™m Jadon, iโ€™ve been doing electrical work for 5 years and love getting new experience and perfecting my craft. I specialize in small commercial and residential, but I also have years experience in big commercial and industrial. I am employed with an electrical company, but like getting more experience with side work. Iโ€™ve worked all around NC and I live near Greensboro, so I donโ€™t mind traveling an hour or 2 out. I work on panels, and put them in/wire them, underground, receptacles and lights, home appliances, remodels, electrical demo, and much more. I take pride in my work and always want my customers happy. I would never accept a job I donโ€™t believe I could finish to my absolute best ability. Thank you and I look forward to doing great work for you!

"Excellent! I was in a bind because my air conditioner went out and I really wanted to at least get a ceiling fan installed so I could survive the heat. Gerald responded immediately, was extremely professional and knowledgeable. He was patient with me and my lack of knowledge. He explained things to me as he went along. He did such an excellent job installing the ceiling fan that I had him install a new light fixture as well. I will definitely be having him come back out to install some recessed lights in my kitchen. I can not recommend him more highly! He takes pride in his work and is a man of his word! Hire him. You wonโ€™t regret it. I sure donโ€™t!"

Generator Install questions, answered by experts

To determine the right size generator for your house, you should calculate the total wattage of the appliances and devices you want to power during an outage. List all essential items, note their start-up wattages, and add them together.

Here are some typical wattage requirements for common appliances:

  • Refrigerator: 600 watts

  • Large dehumidifier: 700 watts

  • Large window air conditioner: 1,400 watts

  • Water heater: 3,000 to 4,500 watts

  • Electric furnace: 5,000 to 25,000 watts

A 7,500-watt generator might be sufficient for essentials like a refrigerator, freezer, well pump, and lighting circuits. However, for high-demand items like a water heater or furnace, a whole-home generator is a better choice. A portable generator may be enough if you only need to power a few critical items.

While home square footage can offer a rough estimate, it is not always a reliable indicator. For reference, here are some typical generator sizes based on square footage:

  • 1,000 sq ft: 6–9 kW

  • 1,500 sq ft: 7–10 kW

  • 2,000 sq ft: 10–14 kW

  • 2,500 sq ft: 12–16 kW

  • 3,000 sq ft: 16–20 kW+

For the most accurate sizing, consult a professional who can calculate your home's peak and average power consumption and recommend the optimal generator.

In most cases, there are no tax credits available for home generators. However, that’s a general statement that applies to federal tax credits, so you might have access to state or local tax incentives. You can check the Database of State Incentives for Renewables & Efficiency (DSIRE) for more information about your area. If you hire a reliable home generator installer, they should also know if there are any state or local perks you can use to reduce your installation costs, including tax breaks and rebates.

While diesel is relatively stable, it won’t last nearly as long as propane and you may have to replace it if it sits unused for too long. Diesel can sometimes struggle to work efficiently or start engines during especially cold weather, so it’s not the best choice for every climate. Compared to fuels like propane and natural gas, diesel generators tend to be noisier and create more exhaust, which isn’t always ideal for home use.

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.

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.
