"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 installations FAQs
Installing a whole-house generator costs about $5,000 on average. Prices range from $1,550 to $8,500, depending on size, brand, fuel type, and assembly. The size of your whole-house generator is the most significant cost factor, with large homes with high energy demands costing the most to power. Types of whole-home generators include:
Portable generators with 1kW–7.5kW capacity: $500–$2,000
Partial generators with 9kW–20kW capacity: $2,000–$6,300
Whole-house generators with 22kW–48kW: $5,000–$18,000
When maintained properly, a whole-house generator can last up to 20 years. Costs to maintain and repair generators vary by location and type of generator, but you can expect to pay about $150 to $300 per year for annual generator maintenance checks. An experienced generator service technician will inspect your generator’s engine filter, starting mechanism, fuel, lubrication, and coolant levels to keep your generator in good working condition for as long as possible.
When choosing the right size generator for your needs, consider a few items to help calculate the wattage you’ll need. Start by determining which household items and appliances you want to power, and then add the wattages together. Check out the wattage of these essential appliances:
Refrigerator: 600 watts
Large dehumidifier: 700 watts
Large window air conditioner: 1,400 watts
Water heater: 3,000 watts
Running home appliances like these requires a partial or whole-house generator. A portable generator may be enough to power your home if you only plan to keep a refrigerator and freezer running.
Here’s what you can run with different wattages and types of generators:
Portable generator:
2,000 watts can handle a large appliance like a freezer or refrigerator, plus a few smaller items like phones or computer chargers.
4,000 watts will keep two large appliances operating and a few smaller devices.
8,000 watts should power most essential appliances and other devices, including a sump pump, well pump, or your dishwasher.
Partial to whole-house generator:
20,000 watts and above will make it seem like your home’s power is still on.
The value of installing a whole-house generator is that your home has guaranteed power, even if the power grid in your area is down. Whether a whole-house generator is worth installing in your home depends on how often you use it, your home’s location, and your lifestyle. For example, installing a whole-house generator is likely worth it if you:
Experience frequent or prolonged power outages
Work from home
Store a lot of cold food
Have a sump pump
Have a pump for well water
Use electronic medical devices
Live in a climate requiring heating or cooling
