30+ years of experience! Our mission is to be a provider that brings back the personal touch with our customers. We will build a relationship that will last a lifetime after you see our quality work. As a locally owned and operated business, we feel invested in our clients and constantly strive for customer satisfaction. Call or message us to schedule an estimate today!

"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."

Generator Install questions, answered by experts

Yes, installing a generator usually increases your property value because buyers are getting the added peace of mind knowing they’ll be able to maintain power through blackouts. In most cases, you should see close to a 100% return on investment (ROI). Keep in mind that home generators usually need a permanent foundation, and installing a concrete slab will likely raise your property taxes slightly.

Generator size requirements vary wildly among properties, but typical generator sizes are listed below based on home square footage:

  • 1,000 sq ft: 6–9 kW

  • 1,500 sq ft: 7–10 kW

  • 2,000 sq ft: 10–14kW

  • 2,500 sq ft: 12–16kW

  • 3,000 sq ft: 16–20kW+

Unfortunately, home square footage isn’t always a good indicator of generator size requirements. Instead, you should call in a professional to discuss which items in your home you’d like to run via your generator. They can calculate peak and average consumption for those items and then size your generator appropriately for optimal performance.

Costs depend on generator type, labor, and additional wiring or transfer switch requirements.

Whole-house generators can last 20 to 40 years with normal operation and proper maintenance. If you look up the specifications for your generator, you may be able to find a lifespan rated in hours of operation. Life expectancy will vary depending on how often and for how long you use the generator each year. Choosing a fuel with low impact like natural gas or diesel can help generators last as long as possible.

You can determine what size generator you need for a transfer switch by matching the switch to the largest outlet on your generator. Larger generators can power up to 10 circuits, while most 5,000-watt generators can provide power to six circuits. So, if your generator’s largest outlet is 30 amps, you’ll need a 30-amp transfer switch.
