"Failed to show up on agreed upon work date due to overbooking. Bid vinyl for an aluminum replacement, then was unresponsive about bidding aluminum. When we decided to go elsewhere, six months later they sent us an invoice for an additional, arbitrary $3k for work not performed. We disputed the invoice and never heard back until we got another invoice another seven months later seeking double the original amount including monthly interest and an ‘overhead & profit’ fee."

Generator Install questions, answered by experts

A 10,000-watt generator can run a small to mid-sized central AC unit (typically up to 3 tons or 36,000 BTU) along with a few other appliances. However, larger AC units or additional loads will require a bigger generator. Consult a local generator installer to ensure you add the correct size generator to your home.

Carbon monoxide emissions aren’t only dangerous to human life, but they also harm our planet. While natural gas generators emit lower levels of CO than other fuel sources, there are still ways to reduce emission levels. For example, shop around for an eco-friendly generator that complies with current emission standards. Also, make sure your generator is serviced regularly to avoid CO buildup. 

The typical cost of a home generator is around $5,000, but prices range from $400 up to $13,000, depending on a few factors. The most significant cost factor is the generator size, as larger generators that can support more square footage usually cost more. You can install an emergency backup generator for between $500 and $2,000 or a partial-home generator for between $2,000 and $6,500. Whole-home generators usually total between $5,000 and $13,000, with some models climbing as high as $18,000.

It might seem counterintuitive, but installing a generator transfer switch will save you money in the long run. While you’ll have to pay between $400 and $2,500 to have the transfer switch installed, you’ll recoup that amount later on when you don’t have to pay for expensive repairs to your appliances, devices, and electrical system that may have burned out, overloaded, or stopped working due to a sudden loss of power or an incorrect hook up of a generator to your home. 

In some situations, yes. Never try to put biofuel into any home generator without checking the specifics first. If a generator has the ability to run on diesel, it can also run pure biofuel (the clear kind made from seed oils, for example). But if you are using biofuel made from animal fats or vegetable oils, the generator will need significant modifications before it can handle a sludgier type of biofuel.
