Get matched with top generator install pros in Bensalem, PA

Q: Can a portable generator power an entire home?

• <div><p>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 <a href="https://www.angi.com/articles/installing-whole-house-generator.htm">whole-home generator</a> instead. </p></div>

Q: What’s the normal lifespan of a diesel generator?

• <div><p>You can expect a diesel generator to last for up to <b>30,000 hours of use</b>, which works out to 20 to 25 years with the proper maintenance, of course. That depends on how much you use it, so a diesel generator used for emergencies a couple of times a year will last a lot longer than a generator that takes over for a faulty electrical grid every month for a day or two. </p></div>

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: Are generators safe?

• <div><p>When installed and used correctly, generators are safe to use. The <a href="https://www.angi.com/articles/power-out-3-tips-safely-operate-home-generator.htm">most critical generator safety tips</a> to keep in mind are:</p><ul><li><p>Never use a portable generator inside an enclosed space, as the carbon monoxide exhaust it creates is lethal.</p></li><li><p>Never attempt to connect your generator to your home&rsquo;s electrical panel independently; hire a professional for this dangerous job.</p></li><li><p>Never overload your generator by connecting more appliances than for which it&rsquo;s rated; you can damage your generator and appliances or even cause a fire.</p></li></ul><p></p></div>

Q: What size generator does my house need?

• <div><p>You can determine what size generator you need by listing the various appliances it will power during an outage. Write down the start-up watt usage, and then add them all together. </p><p>A 7,500-watt generator will run your refrigerator, freezer, well pump, and lighting circuits without a problem. However, you&rsquo;ll need an extra 3,000 to 4,500 watts to run your water heater and another 5,000 to 25,000 watts to run your electric furnace. In these instances, a whole-home generator is your best bet for running your critical equipment.</p></div>

It was done beautiful. They came on time, cleaned up everything and were very professional. I have had Gene several times and would use again without hesitation. As a matter of fact, Gene will be coming out to plant bushes where they took the original ones out.

The flooring installation has held up fine and generally the "tile" has performed well. Unfortunately, the tiles in front of the sink have losted their finish and will have to be replaced. This will cause the overall flooring to be out of balance colorwise. Iffy on the ever using the tile again....
