Q: What size of diesel generator do you need to run a house?

• <div><p>Sizing a generator is a careful process that requires calculating the <a href="https://www.angi.com/articles/electrical-load-calculation.htm">electrical load</a> 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.</p><p>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. </p></div>

Q: Do natural gas generators produce carbon monoxide?

• <div><p>If you&rsquo;re wondering <a href="https://www.angi.com/articles/do-natural-gas-generators-produce-carbon-monoxide.htm">whether gas generators produce carbon monoxide</a>, 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<b> 6 to 12 months</b>. Also, be sure to test your carbon monoxide detectors regularly to ensure they function in the rare case of the generator producing carbon monoxide.</p></div>

Q: How much does it cost to install a generator?

• <div><p>The average cost to install a home generator is $5,200, but total costs can range from $500 to $18,000 or more. The final price depends on several factors, including the generator's size, type, brand, fuel source, and the cost of labor and assembly. The generator's size is the most significant cost factor, as units that can power larger homes with higher energy demands cost more.</p><p>Cost breakdowns by generator type are typically as follows:</p><ul><li><p><b>Portable or Emergency Backup Generators (1kW&ndash;7.5kW):</b> $500&ndash;$2,000</p></li><li><p><b>Partial-Home Generators (9kW&ndash;20kW):</b> $2,000&ndash;$6,500</p></li><li><p><b>Whole-House Generators (22kW&ndash;48kW):</b> $5,000&ndash;$18,000</p></li></ul><p>To ensure you get the right size unit for your needs without overpaying, consider hiring an electrician to calculate the electrical load of your essential appliances. It is also recommended to get at least three quotes from qualified installers to find the best fit for your budget.</p></div>

Q: What size generator do I need to run a fridge?

• <div><p>While the rating will tell you how many watts the refrigerator needs at the peak of its cycle, it requires additional wattage to start. At the bare minimum, you&rsquo;ll need a 1,500-watt generator to get the fridge up and running after a blackout. A 2,000-watt generator should be sufficient for most home refrigerators.</p></div>

Q: Do you have to turn off the main breaker when using a generator?

• <div><p>As a safety measure, you should always turn off the main breaker while operating your generator&rsquo;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.</p></div>

"Shawn and his team were awesome for this project. They understood immediately what realistic budget was, provided very clear itemized project updates as things went on, took care of all the work, and worked with me to complete it all in two days while working around my busy corporate lifestyle. Work was done very clean, conscious of keeping costs low but with quality, and they were fast and friendly. Highly recommend going with them over any of the big 3 companies who will quote you way too much, provide no itemized receipt or options."

We did have a couple of small hiccups, which in my mind a homeowner should expected on literally any remodeling project, and they were resolved quickly.
