Whole-House & Standby Generator Installations

Generator installation services involve selecting, sizing, and installing a generator system to meet the specific needs of your home. A generator installation typically involves an assessment of the power requirements of the systems that will be powered by the generator, as well as an evaluation of the space available for the generator and its components.

The installation process includes the installation of an automatic transfer switch, which allows the generator to switch on when the primary power grid fails.

If you want a whole-home or standby generator for your home today, contact us online or at 586-336-1111.

Generator Repair & Maintenance Services

Generator maintenance and repair services are critical to ensure that generators operate reliably and efficiently. Regular maintenance, such as oil changes and filter replacements, can prevent breakdowns and extend the generator’s life.

You should consider repairs or maintenance if you notice:

  • Reduced performance of your generator
  • Startup problems
  • Strange noises coming from the unit
  • Your unit is consuming more fuel than usual

For quick repairs or tune-ups for your generator, contact Randazzo at 586-336-1111 or reach out to us online.

Generator Replacement Services

Sometimes, a generator may need to be replaced due to age or damage. Generator replacement services involve selecting and installing a new generator system that meets the power needs of the business, organization, or household.

Signs that it’s time for a generator replacement if:

  • Your unit is between 25 – 40 years old

Generator FAQS

Both types of generators work similarly, but a whole-home generator is bigger in that, true to its name, it powers the entire home.
The short answer is that it depends on your budget. A whole-home model is more expensive but can provide more power and is typically more reliable.
