The Question We Hear Most

"How Loud Is It Going to Be?"

It's one of the first things homeowners ask us, and for good reason. Tucson homes sit close together, bedrooms often face the side yard, and many HOAs have rules about equipment noise.

When noise matters, our go-to recommendation is the Cummins Quiet Connect™ series. Cummins has built engines and power systems for over a century, and their home standby line is designed around one thing homeowners care about: running quietly.

By the Numbers

How Generator Noise Compares

Manufacturers publish sound ratings measured at 23 feet (7 meters) with the generator under normal load. Here's how the popular 20 kW class stacks up.

GeneratorPublished sound level
Cummins Quiet Connect™ RS13A / RS17A / RS20A65 dB(A)
Generac Guardian® 20–24 kW67 dB(A)
Generac Guardian® 26 kW68 dB(A)

Sources: Cummins Quiet Connect series specification sheet; Generac published Guardian series decibel ratings. Measured at 23 ft under normal operating load. Actual sound varies with load and installation.

"On paper it's a couple of decibels. Standing next to them on a real install, the Cummins is considerably quieter, and the gap gets even bigger at light loads. Most of the time during an outage your home is only drawing a fraction of the generator's capacity, and that's exactly where you notice it. I've installed and serviced hundreds of these units, and when a customer tells me noise matters, I point them to Cummins." — Mike McNamara, Energysense LLC · 300+ generator installs

It's Not Just the Generator

How We Keep Your Install Quiet

The quietest generator can still be a nuisance in the wrong spot. Placement makes a real difference, and it's part of every install we do.

  • Right location: away from bedroom windows, patios and your neighbor's living spaces wherever code and gas routing allow.
  • Correct sizing: a properly sized unit runs at an easier load, which means less noise.
  • Sensible exercise schedule: we set the weekly self-test for a weekday mid-morning, not Sunday at 7am.
  • HOA help: we review your HOA's rules and help with the approval paperwork.
Common Questions

Generator Noise FAQ

Among the major air-cooled home standby brands, Cummins Quiet Connect™ generators are some of the quietest. Cummins rates its 13–20 kW models at 65 dB(A) at 23 feet under normal load, and in our hands-on experience they're considerably quieter in person than the spec sheets suggest, especially at the lighter loads most homes draw during an outage.
Most air-cooled home standby generators are rated between about 61 and 68 dB(A) at 23 feet under normal load, roughly the range from a normal conversation to a busy restaurant. The actual sound you hear depends on the load, the model and where the unit is placed.
Many Tucson-area HOAs allow standby generators but set rules on placement, screening or noise. We review your HOA's rules, help with the approval paperwork, and recommend a quiet model and location that meets them.
