"Very accommodating and helpful with suggestions when it was noticed that the fan we purchased was defective..our installer came back in the afternoon to install the replacement fan. Check your purchases at Home Depot before you leave the store...our Hunter Fan was definitely returned by a previous customer and then put back on the shelf. The Company and installer handled the job very efficiently and professionally and we would highly recommend."

"Electrical & Security Solutions are the best! I have needed their services more than once to replace lights, a ceiling fan and also to install a new electrical box and breaker for our garbage disposal. Tyler promptly responded every time I called and he and Casey are both friendly, efficient and skillful. Aside from the excellent service, the qualities I appreciate the most is honesty for what work needs to be done and how Tyler is also very budget consciousness."

"Wilson brothers came out to look at the project and provide a bid. They scheduled the inspection with little delay and arrived on time. The man who came was friendly but was very critical of the duct work in my home, which had been installed in a major renovation two years prior by a different company. I'll describe that impact below. He went away promising to provide a bid in two days' time. A week later, I still hadn't heard word and contacted the company. They replied that they would not be able to provide a cost estimate as they were too busy to do the work for several months' time. They indicated that my project was more involved than most A/C installations and for that reason they were choosing not to bid during their high volume time. I was appreciative that they didn't string me along, though frustrated to have to wait a week and then get this answer. The conversation about my previous duct-work project was also worrisome. He described it as an unprofessional job and claimed that it was not up to the building code. The new ducts were flexible, insulated ducts which he stated the code did not permit beyond a run of 12 feet. (Many were much longer than this.) He also pointed out half a dozen places where he believed the ducts had been kinked due to a tight bend. This information obviously led to quite a bit of concern on my part, as well as surprise due to the good heating performance after the previous renovation. I both called the previous contractor and researched the building code on my own. I learned that the Wilson Bros. estimator was incorrect about the building code: flexible *connectors* are limited to 12 feet in length; flexible *ducts* such as what I had are not length-limited. Additionally, all but one of the ducts he had claimed were kinked were not -- the insulation was pinched, but the duct itself was not deformed. The previous contractor noted one kinked duct that they replaced. My suspicion is that the technician does not work with flexible ducts and this led to the competing information. I appreciated the information and it did lead to the repair of one kinked duct. I also appreciated the honesty regarding their ability to do the work in a timely manner, though I would have liked better communication on the topic rather than my having to chase them down."
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

As a safety measure, you should always turn off the main breaker while operating your generator’s backup breaker. In addition, you should also switch off all appliance breakers so you don't have a power surge when the main breaker turns back on. And finally, turning off the main breaker prevents back-feeding, which endangers utility workers with the risk of electrocution. Back-feeding could also destroy the electrical circuits of your neighbors if they use the same power network.

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.

Whole-house generators need to be installed on level ground several feet away from walls and other objects. Because they tap into the electrical system directly, they usually need to be close to your home electrical panel for a transfer switch installation. It also helps with installation if they are near to a gas line or propane tank installation.

Portable generators provide backup power for essential appliances during outages and are easy to relocate.

Generators are usually sized by running watts and starting watts. Ideally, you’ll want a generator that can offer both the necessary running watts and starting watts for everything you need to power without going beyond 90% of its capacity. Calculate your home’s electrical load based on the breakers in your home or adding up the appliance and lighting needs of connected rooms.
