"Tl;Dr; AVOID FOR ANYTHING BEYOND SIMPLE MAINTENANCE OR HVAC ONLY JOBS Our entire experience with the HVAC team has been great. They have been attentive, had no problem with cleaning out the vents, and installed a vent fan for us with no issue. I had no problem pay for what they charged. It was a good chunk of money, but I thought it was worth it for what they had to do. That brings us to the electric and administration in general. We were having a bathroom vent fan replaced and exhausting out from the roof. This required an electrician to come and install the fan. Additionally he was going to be looking at some electrical anomalies we were seeing in the house (GFCI flipping, inconsistent current). He wasn't told about the fan at all. He wasn't even really told about the GFCIs flipping either. So when he gets here, he gets sprung on him these additional things. He does the GFCI thing, isn't able to see the inconsistent current while he is here so doesn't do anything with that, and then goes to do the bathroom. He says he ran new conduit. Inspecting what is there myself, I can tell you there is no new conduit. Why would new conduit be ran when no new switches, no new functionality was added? He charges us well over $500 for installing that fan AND HE LEAVES A HOLE AROUND THE FAN DIRECTLY TO THE ATTIC. How does a company charge that without completing the job with no intention on following up? We contest the price we were charged for service with management and they keep dragging their feet to "try to learn more", offering to refund a charge that I wasn't trying to contest. They keep promising to call back but aren't. There is no communication between different members of the team except through notes that don't tell them anywhere close to the full story. When I finally heard back from them today, they came back with a "Well your wife was okay with paying it and the work" when she was under the (admittedly presumptuous) impression that the HVAC guys would fix the fan because, again, why would they leave a hole in the ceiling like that. Not only that since she she paid the cost there will be no discussion of refund for work they didn't do. The communication is extremely poor from them. Do not use them from anything that is at all more complicated that requires multiple departments or this is the risk you run."

Generator Install questions, answered by experts

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.

No, this is extremely dangerous, often illegal, and you should never attempt it. If you connect your generator to your home without a transfer switch, the generated power can backfeed, essentially flowing back into the utility lines. Backfeeding exposes a significant threat of fatalities or harm to you and utility personnel, in addition to jeopardizing the structural integrity of your home.

If you’re wondering whether gas generators produce carbon monoxide, know that natural gas generators do not produce carbon monoxide if they are functioning properly, as natural gas burns cleanly. However, if the generator malfunctions and the gas does not burn completely, there is potential for carbon dioxide to be produced. To prevent malfunctions, it's crucial to perform regular maintenance, including running the generator weekly and scheduling professional inspections every 6 to 12 months. Also, be sure to test your carbon monoxide detectors regularly to ensure they function in the rare case of the generator producing carbon monoxide.

You may need a permit for a portable generator if you’ll be installing a transfer switch for your primary residence or similar work. Otherwise, a permit for other uses may not be necessary. Check your local building codes or ask a local generator installer for more information about your local regulations.

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.
