"I used JP McCurdy to install recessed lights in my living room. The ceiling was sloped and very high and Shazeeb and Nico did a great job. They also installed overhead lights in bedrooms and put in a 240-volt outlet for a washer/dryer room. They communicated with me about my preferences throughout the job. Their work was professional and clean. They also patched the holes they made, which some electricians wouldn’t do."

"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 questions, answered by experts

To power a central air system during a power outage, the whole-house generator will need to be at least 5,000 watts, and this number will significantly increase for larger units. Check the specific wattage requirements of your AC unit to choose the right generator size. Consider consulting a generator installer to ensure your whole-house generator meets your electrical load needs.

Generally, you’ll want to keep between 60 and 70 feet between the generator and the transfer switch. There are a few reasons for this, including:

  • The distance reduces the noise coming from the generator into your home.

  • It increases efficiency because you won’t have a voltage drop from this short of a distance.

  • Prevents carbon monoxide poisoning: keep at least 15 feet between your generator and an open window. 

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.

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.

Sizing a generator is a careful process that requires calculating the electrical load of your entire house. You have to take into account every device you want to use and their wattage requirements, plus the wattage needed to start them, and look for a generator that can safely run all that at around 80% capacity.

In more practical terms, a small home can run on a 10,000-watt generator (and if you only want to power a few key appliances, much less than that). A mid-sized home may need something between 15,000 and 22,000 watts. Larger homes require 25,000 watts or more.
