"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."

Full Service Electrical and installation provider. If you suspect your electrical system could be damaged or malfunctioning, contact us right away. We will send a knowledgeable electrician out to identify the exact issue that is affecting your system. However, we do far more than just repairs, from LED lighting installation to electrical panel upgrade. At Kelco Electric, it's our job to make sure that all our electrical repairs are done carefully and correctly. When your electrical system is in need of repairs, it's dangerous to let the problem remain unsolved. Electrical systems are complex and interconnected, so when one component isn't working properly, the entire system is at risk. We know that your life is busy and dealing with electrical problems or upgrades isn't exactly on the top of your list. However, electrical work isn't something to be taken lightly. This is why our electricians are here to make sure you and your family are safe from electrical problems. We will always work to make sure your needs are met and all work is completed to electrical codes at reasonable prices.

"Kelco Electric did a great job. Randy and Isaiah were very professional and efficient. Arrived on time and had job finsihed within one hour. I will hire them again when I need electrical work."

Generator Install questions, answered by experts

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 cost to install a whole-house generator averages at $5,200, but costs can range from $1,500 to $8,900, depending on the type and size of the generator, and the labor required to install it. To find the best deal while still ensuring the unit meets all the needs of your household, hire an electrician to calculate the electrical load of your must-have appliances and electronics beforehand so you don’t pay for more power than you need. As always, be sure to get at least three quotes to find the ideal fit for your needs and budget.

It is safe to run a generator continuously, but you must follow safety protocols to ensure personal and home safety. Read the manufacturer’s instructions for specific recommendations, but the general recommendation is to turn generators off overnight or when you’re away from the house. Overworked generators can pose a fire hazard and if your generator is not in a well-ventilated area, running it continuously could lead to carbon monoxide poisoning.

In many cases, yes. There are models called dual-fuel generators and fuel switches, but only between certain types of fuel. For example, with the right setup you can convert a generator from natural gas to propane. Some allow switching between diesel and gasoline. There are even tri-fuel generators available in some cases, which adds a large layer of security if you are worried about fuel availability in times of crisis. Always check your generator capabilities and manual instructions before trying to switch fuels. Some generators can use another fuel but may need a fuel conversion kit to prep them first.

In some situations, yes. Never try to put biofuel into any home generator without checking the specifics first. If a generator has the ability to run on diesel, it can also run pure biofuel (the clear kind made from seed oils, for example). But if you are using biofuel made from animal fats or vegetable oils, the generator will need significant modifications before it can handle a sludgier type of biofuel.

By submitting this question, I acknowledge and agree that Angi may publicly display my name, city, state, and question on the website for professionals and others to see.
