"We've used Wilson Bros. for nearly 18 years for our major systems work. They've installed a 2-zoned HE gas furnace and 2 water heaters and done routine maintenance. Have also responded immediately in one or two emergencies. This is a family run organization. EVERYONE from accounting to technicians to estimators to the owner of the company are professional, personable and know what they're doing. And they get things done. They are not the cheapest in town, but their pricing makes sense and i'm willing to pay for the continuity. For less important things i'll use journeyman plumbers. But for the important stuff Wilson Bros. are my go-to folks. I can't say enough good things about them, if you couldn't already tell."
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 FAQs, answered by experts

Most 200-amp panels have 40 to 42 slots, which can accommodate 40-42 single-pole breakers or 20 double-pole breakers. Some panels can accept even more circuits through the use of tandem breakers. The exact number of breakers allowed is determined by the panel manufacturer's rating, which you can find on the panel itself. It is important to avoid using all breakers at the same time; as a general rule, you should not use more than 160 amps of power at once to prevent overloading your 200-amp system. For specific guidance, it's best to check your panel's rating or consult with a qualified electrician.

Old electrical systems may have more problems than newer ones. In some cases, like if your home has aluminum wiring, it may be necessary to update your electrical system. You should also update your home’s wiring if it still has knob and tube wiring, which is considered dangerous by modern building standards. If that applies to you, get in touch with an electrical professional near you to obtain a quote.

The wrong-sized wire can lead to several safety hazards, including structural fires, surges, power outages from tripped breakers, and electrocution. It’s important to follow the American Wire Gauge system and the National Electrical Code guidelines to safely wire a home. Electrical wiring is not safe for homeowners to handle and is best left to a licensed electrician.

No, a ceiling fan doesn’t have to be wired to a switch, but it’s often more convenient. You can use the included pull chain if your ceiling isn’t too high or install a remote module later, as they are a cheap, easy-to-install option that’ll let you control both the fan and light fixture.

Call your utility company immediately. Do not go outside, even in your own yard, and keep pets indoors. Downed power lines pose a serious electrocution hazard. They can also cause large power surges that could damage your appliances, so it’s a good idea to shut down power to your home if possible. If your breakers trip, leave them off until the utility company finishes its repair work.
