"Office staff was super helpful in getting this generator installed. And, on the day of installation, the technicians never took a break. At the same time, were very accommodating and and answered our questions fully. Great install. I would (and have) recommend Hurricane Homes."

"Paul was professional , polite, and timely. His pricing was more than fair. He installed 4 outlets (two double and two quads) while adding 2 circuits to our basement. He did an excellent job and we had him come back to install another cable outlet and electrical outlet in a bedroom/office. He cleaned the areas where he worked prior to leaving. We will certainly hire him for any future electrical work."

"Donovan did fantastic work, reasonable prices, immaculate cleanup. Went above & beyond to disclose a serious Comcast wiring issue where transformer was missing on outside of house while there major wire & grounding wire was inside my home! He helped me put together a report to BBB who immediately got Comcast to rectify the non-code compliant & dangerous situation. I just thought my poor internet was something I had to live with because seven b years of Comcast techs coming to my home said nothing was wrong. Seven years & dozens of techs who were not even aware let alone fixed the non-code compliant install they did! Thank God that Donovan at Any Electrical Need & the BBB got Comcast to rectify things. Clearly all those Comcast techs needed retraining."

Generator Install FAQs, answered by experts

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.

If you’re wondering whether gas generators produce carbon monoxide, 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 6 to 12 months. Also, be sure to test your carbon monoxide detectors regularly to ensure they function in the rare case of the generator producing carbon monoxide.

DIY is possible for basic setups. Professional installation ensures safe and proper electrical connections.

Natural gas and electricity rates vary significantly based on location, and pricing can change over time, too. It’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’s initial costs and maintenance needs, as well as its noise level and if it can comfortably power all your home appliances.

Sizing a generator is a careful process that requires calculating the electrical load 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.

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.
