"We had a list of items that needed to be completed (driveways lamps posts/lighting, cathedral ceiling fan, various fixtures, etc.) and a couple of more involved projects we were thinking of doing, like a hot tub installation. Harland Electric was responsive, prompt, courteous and professional throughout the entire process—from initial contact, estimate and work. They itemized each of the projects so that we could pick and choose the work that needed to be done, and were helpful in detailing the complexities of certain projects and weighing the pros and cons of having electrical work done. During the course of coming to the house and knocking every item off of our list (which took 1.2 days worth of work/time), they also alerted us to an electrical fire hazard for an outdoor flood light that another electrician from another previous company just left and said was okay. They replaced the entire light and wiring and now it looks great the way it illuminates our side yard! We even overpaid at the end of the project and they immediately let us know! They are scheduled to return in the spring to install a pool heater and we have no doubt they will do a great job. Overall, great service, highly ethical company and good value overall. Highly recommend!"

"The two young men who performed the installation were informative, professional, cordial, and they left the scene spotless. There was a technical problem with the engine on the generator itself, which they weren't able to help with, because they weren't licensed to work on the specific brand of generator. That might be something to check on before hiring for this type of job."

"The furnaces were replaced in two different houses without any problems. The generator was placed in one of the houses with many delays. Waiting for parts we were told. When it was finally assembled it worked but daily test runs were happening. When we called to have our yearly check we were told it should only run once a week. A part needed to be replaced. Wilson Bros. shared that expense. It ran for about the next 5 years with constant maintenance but this year the mother board is gone. Wilson Bros have been wonderful but I question the quality of their equipment. One of the gas furnaces also requires costly maintenance. We never had this with our other gas furnaces. Love Wilson Bros. Don't like their replacement equipment. I just thought new things should last a little."
Three of the five heads are marked by the numbers in the blue circle. On the inside of the house is where you will find the mounted units. The slim ducts run alongside the white arrows and will eventually be covered to match the exterior of the house.
The slim ducts in the basement ceiling that connect from the branch box all the way to the 5 different heating and cooling units. These will be covered by the ceiling tiles once the job is finished.

Generator Install questions, answered by experts

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.

Generators are safe to use as long as they are installed and operated correctly according to the manufacturer's recommendations. The most critical safety tips are to never use a portable or fuel-powered generator inside an enclosed space due to the risk of lethal carbon monoxide poisoning; always operate it outdoors where fumes can dissipate away from your home. Additionally, never attempt to connect a generator to your home’s electrical panel yourself—hire a professional to ensure the setup meets safety standards. Finally, avoid overloading the generator by not connecting more appliances than it is rated for, as this can damage your equipment or cause a fire.

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.

Setting up utilities on a vacant property usually takes at least a few months, or between 6 weeks to 16 weeks. This process requires working with the local planning and zoning department, hiring a building contractor or engineer to design the utility layout, securing permits, laying the lines, and connecting the utilities.

If you’re deciding between a solar battery versus a generator for the best backup power solution, you can take a few factors into consideration. Solar batteries are quiet while generators can be quite loud. Generators have a lower up-front cost, but they require fuel and ongoing maintenance while solar batteries are more expensive but don’t have many ongoing costs.
