Get matched with top generator install pros in Lansing, IL

Q: What size whole house generator do I need to run central AC?

• <div><p>To power a central air system during a power outage, the whole-house generator will need to be at least 5,000 watts, and this number will significantly increase for larger units. Check the specific wattage requirements of your AC unit to choose the right <a href="https://www.angi.com/articles/whole-house-generator-sizing.htm">generator size</a>. Consider consulting a generator installer to ensure your whole-house generator meets your electrical load needs.</p></div>

Q: What are the benefits of a portable generator?

• <div><p>Portable generators provide backup power for essential appliances during outages and are easy to relocate.</p></div>

Q: Is a natural gas generator less expensive than using electricity?

• <div><p>Natural gas and electricity rates vary significantly based on location, and pricing can change over time, too. It&rsquo;s possible that in locations where natural gas is particularly inexpensive, it will cost less than grid-based electricity will. However, you should also factor in the generator&rsquo;s initial costs and maintenance needs, as well as its noise level and if it can comfortably power all your home appliances.</p></div>

Q: How do I reduce AC startup power for a generator?

• <div><p>To reduce AC startup power for a whole-house generator, install a soft start kit or hard start capacitor, which lowers the initial surge by gradually ramping up the compressor. Using a smart load manager can also help by staggering startup loads, preventing a system overload and future costly repairs.</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>
