"It was a absolute pleasure working with the Wilson Brothers team from sales, site planning and install. The install and electrical teams were very professional and demonstrated in depth knowledge of the product and their craft. They arrived at the time specified and worked very neatly and in an organized fashion. We would absolutely recommend Wilson Brothers for any Heating/AC needs."
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 FAQs, answered by experts

Energy output depends on turbine size, average wind speed at your site, and system efficiency. A 5 kW turbine in a good wind location can generate 8,000 to 12,000 kilowatt-hours per year, which may cover a large portion of an average home’s needs. Accurate output estimates require a professional wind assessment and a review of your household’s energy usage patterns.

Costs range from $500 to $2,500, depending on generator type and installation complexity.

An undersized whole-house generator has the potential to overheat and shut down when you try to run a central AC system. This scenario can not only damage the whole-house generator, but can also trip your home’s breakers or cause electrical damage. To avoid this situation, hire a local generator installer to correctly size your whole-house generator.

A 10,000-watt generator can run a small to mid-sized central AC unit (typically up to 3 tons or 36,000 BTU) along with a few other appliances. However, larger AC units or additional loads will require a bigger generator. Consult a local generator installer to ensure you add the correct size generator to your home.

The cost to install a whole-house generator averages $5,200, with a typical price range of $1,500 to $8,900. However, total costs can vary from $400 for a small portable unit to over $18,000 for a large-capacity system. The most significant cost factor is the generator's size and capacity, but other variables include the brand, fuel type, and labor for assembly and installation.

Generator costs can be broken down by type:

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

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

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

To avoid paying for more power than you need, consider hiring an electrician to calculate the electrical load for your essential appliances. It is also recommended to get at least three quotes to find the best deal for your specific needs and budget.
