"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.

Electrical questions, answered by experts

The major difference between a GFCI breaker and an AFCI breaker is that a GFCI breaker protects against fatal shocks while an AFCI breaker prevent electrical fires. A GFCI breaker senses when the electrical current to ground is overloaded and trips to prevent major accidents or injuries. AFCI breakers trip when it detects dangerous electrical arcing.

It’s recommended that you test GFCI outlets monthly with the test and reset buttons. At minimum, you should test GFCI outlets when entering a new season, or every three months. These are important home safety features that you should ensure work properly.

Yes, an electrical fire can start even if nothing is plugged into an outlet. While a correctly functioning outlet poses no risk, a fire can be caused by faulty wiring, damaged outlet components, an overloaded circuit, or other electrical problems hidden behind the walls. If you suspect a fault, immediately turn off the circuit breaker and contact a professional electrician to diagnose and repair the issue.

Typically, when a 3-way switch only works when one switch is on, this is one of the most telltale indicators that the switch has gone bad (although this could also be the result of faulty or loose wiring). To diagnose the issue, toggle each switch until the light comes on. Once it’s on, toggle each switch separately again; the switch that doesn’t turn the light off is the bad switch. 

By nature, two-prong outlets aren't grounded—but the box they run to might be, which makes them safer. The safest way to test if an outlet is grounded is to purchase a circuit tester, which cost about $20 at home improvement stores. 

If you discover your outlet (or outlets) aren't grounded, know that this greatly increases your risk of personal injury and electrical fires. You may want to consider installing new three-prong ground fault circuit interrupter (GFCI) outlets. On average, the cost to install GFCI outlets is about $210 per outlet.
