"Tri-County Electric Services was able to send a plumber out the next day to provide estimates for a few projects in my home. Chris M. arrived at my home and was professional, knowledgable, straight forward, and friendly. He quoted me fair prices to install a new toilet and new kitchen faucet, both of which I had previously purchased independently and had at home ready to install. I was very happy that he was able to complete the installs that day. He also fixed a minor leak below a bathroom sink. All around a great experience! I will definitely hire them again for future plumbing needs. Chris explained that the company recently added a plumbing division to complement their electric services. Thank you for a job well done!"

"On Thursday, the technician (David) came to my house to look at two projects: replacing a leaking electric water heater, and installing a new gas line (in my crawlspace) to my masonry fireplace so I can convert from wood to gas logs. He explained my options, and quoted prices for these options. I asked if he could do the work on the upcoming Saturday, and he scheduled this before he left! I ordered the gas tankless water heater and the gas line to my fireplace. By the way, I had 3 different plumbers look at this work, WyattWorks had the lowest prices. On Saturday David and Alex arrived early in the morning and worked past 6:30 PM to complete both jobs. The installations were great. Everything to code, and with neat, high quality workmanship and thoroughly tested. They cleaned up the work areas and hauled away my old water heater. In other words, a typical WyattWorks job."

Generator Install FAQs, answered by experts

The average cost to install a home generator is $5,200, but total costs can range from $500 to $18,000 or more. The final price depends on several factors, including the generator's size, type, brand, fuel source, and the cost of labor and assembly. The generator's size is the most significant cost factor, as units that can power larger homes with higher energy demands cost more.

Cost breakdowns by generator type are typically as follows:

  • Portable or Emergency Backup Generators (1kW–7.5kW): $500–$2,000

  • Partial-Home Generators (9kW–20kW): $2,000–$6,500

  • Whole-House Generators (22kW–48kW): $5,000–$18,000

To ensure you get the right size unit for your needs without overpaying, consider hiring an electrician to calculate the electrical load of your essential appliances. It is also recommended to get at least three quotes from qualified installers to find the best fit for your budget.

The amount of time a standby generator can run continuously is around 3,000 hours on average. However, standby generators can generally run indefinitely as long as they have a continuous fuel supply. Generators hooked up to a home’s natural gas supply are the best option for extended usage, as these won’t rely on a finite fuel supply based on how much you have in storage. Generators running on liquid propane or diesel won’t last as long, as these require fuel storage and regular refueling to stay running.

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.

Whole-house generators can run continuously for extended periods, even for weeks at a time (around 400 to 500 hours), as long as they have a sufficient fuel supply. However, this type of extensive use will increase wear and tear and can shorten the generator's overall lifespan. During long periods of operation, it's important to check and refill the engine oil as needed, potentially as frequently as daily depending on the model. If your generator uses a fuel tank, ensure it is kept full to prevent unexpected shutdowns.

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