"Following a home inspection I needed some odds and ends electric work done. Add 4-5 GFCI, ground a few plugs, etc. Also there were two knob and tube wires totaling under 20” in length that needed replacing. Items that most handle homeowners can do but I wasn’t allowed to because of the selling process, etc. I also needed it done within 7 days. A guy from Cox Electric came to my house to give me an estimate. (I’ll get back to that…) The guy that DID come to fix (Bill from another company) took 3 hours, did a beautiful job, and charged me $850. What was Cox Electric estimate? $3250. With materials costing under $50, this comes to over $1000/hour. While not against the law, gauging homeowners that are going through the process of selling a home is unethical."

"A lot of issues with power surges in my house. Dan came out on a Saturday and spent about an hour diagnosing my problem. He told me that my electrical panel would need to be replaced (not a big surprise as it was almost 50 years old) He had an emergency call for a medical office and had to leave. Promised that he would be back in two or three hours. He came back as promised but said that he had called around and would not be able to get the parts that he would need for my job until Monday. He was able to set up my panel to safely get me through the weekend. He gave me an estimate for the work. Came back on Monday and replaced my electrical panel. Final bill was $50 above estimate. I was very happy with the cost but the work he does is excellent. This is the second project that he has done for me. I would without reservation recommend him. Suoer nice guy."

Generator Install questions, answered by experts

Generators run on a variety of fuel types, ranging from natural gas to solar power. Keep in mind that fuel costs varying by type:

  • Natural gas: $2,000–$21,000 per year 

  • Liquid propane: $2,000–$21,000 per year

  • Diesel: $3,000–$20,000 per year

  • Gasoline: $500–$3,000 per year

  • Solar generator: $2,000–$25,000 per unit

  • Battery backup: $10,000–$25,000 per unit

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.

It might seem counterintuitive, but installing a generator transfer switch will save you money in the long run. While you’ll have to pay between $400 and $2,500 to have the transfer switch installed, you’ll recoup that amount later on when you don’t have to pay for expensive repairs to your appliances, devices, and electrical system that may have burned out, overloaded, or stopped working due to a sudden loss of power or an incorrect hook up of a generator to your home

These advanced generators use a key fob or a smartphone app to remotely start, which is ideal for getting power back on immediately without venturing outside. This feature is more common on whole home generators, but you may be able to find it on large portable generators, too.

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.
