"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

While diesel is relatively stable, it won’t last nearly as long as propane and you may have to replace it if it sits unused for too long. Diesel can sometimes struggle to work efficiently or start engines during especially cold weather, so it’s not the best choice for every climate. Compared to fuels like propane and natural gas, diesel generators tend to be noisier and create more exhaust, which isn’t always ideal for home use.

Many services include assembling the unit and securing it in the window. Confirm with your provider.

A portable generator can supply power to selected appliances and circuits in a home, but it's generally not designed to handle the entire household's electrical needs simultaneously. Portable generators have limited wattage capacity, so they are only designed to power essential devices and electronics temporarily until local power is restored. If your power needs outweigh the capabilities of a portable generator, consider installing a whole-home generator instead.

The cost to install a whole-house generator averages at $5,200, but costs can range from $1,500 to $8,900, depending on the type and size of the generator, and the labor required to install it. To find the best deal while still ensuring the unit meets all the needs of your household, hire an electrician to calculate the electrical load of your must-have appliances and electronics beforehand so you don’t pay for more power than you need. As always, be sure to get at least three quotes to find the ideal fit for your needs and budget.

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.
