"GenPro installed a Home Generator for us. Andrew Spitzmueller and his team were dependable and reliable. Did what they said they would do. When they encountered roadblocks with sub-contractors and permit inspectors, they worked diligently to resolve the situation. They are honest and trustworthy people. Highly recommend them."

"A1 Plus Electrical had the best price, and the electricians and plumber did excellent work! The only problem experienced was that it took 5 to 6 weeks for A1 Plus to get the permits approved after stating that they could get the permits approved and install the generator within 2 weeks. All other companies couldn't do the work for at least 2 months or longer! I had to contact A1 Plus general manager to get things moving after several permit submissions were rejected by the city. A1 Plus mitigated this time inconvenience by installing an electrical outlet in the garage at no cost, and once the permits were approved, everything was done within 7 days. Permits were approved on Friday, and installation started on the following Tuesday, and city permit inspections were done on the following Friday! All within one week! Would I hire A1 Plus to install my generator in the future? YES!"

"Full turnkey installation of a Generac 17KW standby generator to wire my whole house for back up power was performed and the whole process was excellent. 

Very easy process once decision to purchase was made, I initially received an estimate one year prior to performing the work.  I had many questions and they gladly answered and provided me with as much information as possible.  When I contacted for new proposal the following summer in 2010 they rebid the job for a whole house install and a limited install, and due to upgrade from manufacturer using an improved transfer switch, my cost for whole house install was only marginally more than the estimate in 2009 for a limited installation so I chose the whole house option.

The entire process was very easy once I signed the bid.  Took about 2 weeks for the generator to come in, during that time they came to my home without me there and set the pad for the generator.  Once the generator arrived they set an install date and the process took about 1 week.  Generator was delivered, gas lines wire installed, electrical transfer switch and all other wiring and install necessary.  The work was done as scheduled and completed on time. 

I met the technician at the agreed upon time when installation was complete and they reviewed the operations of the generator with me.  He explained and demonstrated how it operates and showed me how it would work in event power was lost.  It is automatic and there is nothing for me to do in the event of a power outage or to run a maintenance check.  The generator is set to run a test cycle for about 5 minutes once a week and has warning lights that will notify me of any problems or let me know know if battery is dead or needs charging.

Overall we are very pleased with the installation, cost, and service from Storm Guardian Generators.  We have had one 5 hour power outage since the installation, I was at the store when power went out and the generator started automatically and restored power before my wife could find a flash light and go check on the generator.  Power surged and went on and off a few times as it was brought back online by electric company and my generator restarted without fail within a minute of losing power each time.wiring"

Generator Install FAQs, answered by experts

No, you should never plug a generator directly into a wall outlet in your house. This practice is extremely dangerous, often illegal, and can cause "back-feeding," where power from the generator flows back into utility lines, creating a life-threatening hazard for utility workers. It can also damage your home's electrical system, including appliances like pumps and HVAC fans. If the main power is restored while the generator is connected, it can destroy the generator and cause an electrical fire. To safely connect a generator, you must use a professionally installed transfer switch or an interlocking kit, which prevents back-feeding by disconnecting your home from the utility grid before the generator provides power.

These advanced generators use a key fob or a smartphone app to remotely start, which is ideal for getting power back on immediately without venturing outside. This feature is more common on whole home generators, but you may be able to find it on large portable generators, too.

In many cases, yes. There are models called dual-fuel generators and fuel switches, but only between certain types of fuel. For example, with the right setup you can convert a generator from natural gas to propane. Some allow switching between diesel and gasoline. There are even tri-fuel generators available in some cases, which adds a large layer of security if you are worried about fuel availability in times of crisis. Always check your generator capabilities and manual instructions before trying to switch fuels. Some generators can use another fuel but may need a fuel conversion kit to prep them first.

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.

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.
