What is a home standby generator?

A home standby generator is a backup power system that automatically supplies electricity to your home during a power outage. It is permanently installed outside your home and is designed to turn on within seconds of a power failure. It is powered by natural gas or propane and can provide enough electricity to power your entire home or just the essentials.

Why should you install a home standby generator?

  • Protection from Power Outages: A standby generator ensures that your home has power during an outage, which can be especially important if you have medical equipment that requires electricity or if you live in an area prone to natural disasters.
  • Increased Home Value: Installing a standby generator can increase the value of your home, making it a worthwhile investment.
  • Convenience: With a standby generator, you don't have to worry about running extension cords or setting up portable generators during a power outage.

What size generator do you need for your home?

Choosing the right size generator for your home is important to ensure that it can provide enough power during an outage. The size of the generator you need depends on several factors, including the size of your home, the number of appliances you want to power, and your budget.

Home standby generators come in a range of sizes, typically measured in kilowatts (kW). The size of a generator needed for a particular home will depend on the electrical load that needs to be supported during a power outage.

For small homes or essential circuits, a 7-10 kW generator may be sufficient. For larger homes, a 15-22 kW generator may be more appropriate. Some homes may require even larger generators, up to 45 kW or more, depending on the size of the home and the specific electrical demands.

It's important to consult with a qualified electrician to determine the appropriate size generator for your home based on your specific needs and electrical load.

Have had Castro out several times for troubleshooting as well as general electrical work (including outdoor receptacle and fan installation). I have been totally blown away by everyone’s professionalism, personable affect, and attention to detail. Communication is great. Prices appear very reasonable. They were able to diagnose a tricky safety hazard and remedy the situation thoroughly. I cannot recommend them enough!

Specifically I want to say a special thanks to Peter for his diagnostic work and attention to detail. He is also incredibly kind and clearly loves his work and the people he helps. He’s very smart and I trust him fully

It’s a pleasure to work with a service provider that knows how to get customer service right! Castro Electrical worked with me to get a critical electrical upgrade completed on a schedule that was important to me. Even if that meant inserting a job into an already full calendar, modifying the estimate and job specifications per my requirements, or having Peter and Carter (both managers) themselves come out and do the work. This team, together with their boss and owner Paul really differentiates themselves with their flexibility and customer focus while also being excellent electricians who know the job and how to do it with high quality!

Carter from Castro came out quickly to do an estimate and was very responsive throughout the process. He gave us different options for how to do the job, and did not push the more expensive one. Once the job was booked, they were able to complete it very quickly. The electricians were professional and courteous, and did a fantastic job. Will definitely use Castro again for future jobs.
