Fernando and Gabriel did an outstanding job installing my Generac 22K generator. The concrete pad they poured with the pre-piped wiring was excellent and resulted in a very clean look. They conducted a thorough test to ensure everything was just right. I am a very satisfied customer and highly recommend them.

FAQ

Frequently Asked Questions About Generator Service

We offer a wide range of generators suitable for both commercial and residential use, including models from leading brands like Generac, Cummins, and John Deere. Whether you need a standby generator for large-scale operations or a portable unit for home use, we have options to meet all needs.
We recommend servicing your generator at least once a year or after 200 hours of use. Regular maintenance includes checking the engine oil, filters, and battery, along with a full system inspection to ensure reliability and efficiency.
Load bank testing involves simulating the electrical load to test a generator’s ability to run at its full capacity. Our process includes warming up the generator, applying measured loads, monitoring performance, and adjusting settings as necessary to ensure optimal operation.
Yes, our generator installation services include a comprehensive site assessment, system design, installation by certified technicians, electrical hookup, and thorough testing to ensure everything is functioning correctly.
If your generator fails during a power outage, immediately call our 24/7 support line. Our technicians can guide you through basic troubleshooting, and if needed, we will dispatch a repair team to your location to resolve the issue promptly.
The cost of a generator for a 2000 square foot house typically ranges between $3,000 and $6,000, depending on the generator’s power capacity and type. For most homes of this size, a generator with a capacity of 10-20 kilowatts is adequate to power essential appliances and systems during an outage. The price may vary based on whether you choose a portable or a standby generator, with standby models being more expensive but offering more convenience and power.
To determine the right size generator to run the air conditioning system in your house, you need to know the total wattage required by your AC unit. Typically, central air conditioners require about 3,000 to 5,000 watts to start up and around 1,500 to 3,000 watts to run. Therefore, a generator with at least a 5,000 to 7,000 watts capacity is usually sufficient for running a single central AC unit along with a few other essentials.
A 3000 watt generator can typically run a combination of several small appliances or a few larger ones simultaneously. For example, it can handle the load of a refrigerator (about 600 watts), a microwave (up to 1000 watts), several lights (40-60 watts each), and a TV (around 200 watts). It can also power one or two small window AC units or a single mid-sized portable heater. It’s important to calculate the total wattage of all devices you plan to run at the same time to ensure the generator can handle the load without being overloaded.
