Cummins RS17A — 17kW Standby Generator
17kW air-cooled standby generator, Natural Gas / LP Vapor. The typical three-bedroom DFW home with a single AC system.
Representative manufacturer image of the range. Enclosure finish, color and dimensions vary by model and configuration — see the specifications below for this unit.
17 kW Natural Gas / LP Vapor Air-cooled Aluminum
The RS17A is an air-cooled unit in an aluminum enclosure, which is the right build for a residential yard: no radiator loop to service, a smaller pad, and a footprint of 34.1 x 36 x 27.3 inches at 531 lb.
It runs on natural gas or LP vapor. On natural gas there is no tank to fill and no runtime limit as long as the utility main holds pressure, which is why it is the default choice on almost every DFW home that already has gas service.
Equipment price
$5,326.86
Equipment only — installation quoted separately
The RS17A is sold by UTS ElectricPros, an authorized Cummins dealer in Dallas–Fort Worth. Buying through an authorized dealer is what keeps the manufacturer warranty valid — equipment bought from an unauthorized reseller frequently is not covered, and owners tend to find that out at the worst possible moment.

$12,500 - $15,500
$12,500 - $15,500
Equipment plus professional installation: electrical by our licensed electricians, gas line by a licensed plumber. We quote after a survey because gas line runs, panel location and permits differ at every address. We don’t guess, and we don’t pad.

What the RS17A does that the spec table does not show
Intelligent Load Management
The generator can control up to 4 loads and continuously monitors how much power each one needs, then restores only the loads it has capacity to run. This is what makes a 20kW unit cover a house with two air conditioners.
Patented Crank-Only exercise mode
The weekly exercise cycle can crank the engine and run diagnostics without actually starting it, which reduces wear, fuel use and the noise of the exercise run.
Remote monitoring, built in
Remote monitoring is standard on every unit. From a computer, tablet or phone you can check status, change the exercise schedule and start the generator manually.
5-ton air conditioner start
Rated to start and run a 5-ton A/C under full pre-load — the load that decides generator sizing in Texas.

Questions about the RS17A
How much does a Cummins RS17A cost installed in Dallas-Fort Worth?
The RS17A equipment price is $5,326.86. Installed in DFW, a typical 17kW job runs $12,500 - $15,500 all in. The spread comes from four things: how far the pad sits from your gas meter, whether the gas line carries the added load or has to be upsized, the run from the generator to your electrical panel, and what your city charges and requires for permits and inspection. We put the installation number in writing after a free site survey.
What will the RS17A actually run?
Most of a 2,000-2,500 sq ft home with load management on the larger AC. Final confirmation comes from a load calculation against your actual panel, which we do at the survey.
Do I need a transfer switch with the RS17A?
Yes. A standby generator cannot be code-compliantly connected without an automatic transfer switch - it is what keeps your generator from backfeeding the utility line and endangering line crews. The switch is sized to your electrical service, not to the generator, so we confirm your service size at the survey before specifying it.
Is the RS17A in stock?
Availability changes weekly. A refundable deposit reserves a specific unit and locks the equipment price for 90 days, which is the practical way to hold one while the survey and permit work happen. If we cannot source it in a reasonable window, you get the deposit back.
Same size, different build
Other 17kW configurations
Same 17kW output. What changes is the enclosure, the transfer switch and whether a cold-weather package is fitted — not the power.
Step up or down
Is 17kW the right size?
The next capacity either side in the air-cooled range. If you are not sure which way to go, the sizing calculator works it out against your own house rather than its square footage alone.
Down to 13kW — less headroom, lower install cost.

Want the RS17A priced for your address?
Equipment is $5,326.86. The installation number depends on your property, and the only honest way to get it is to come look. That visit is free.
What it is for
Whole-house backup power, started automatically
The grid goes down and the house stops with it. In Texas that is not an inconvenience for long: in February it is heat and frozen pipes, in August it is air conditioning, and a house without either becomes uninhabitable within hours rather than days.
Why it becomes urgent
Winter storms and the spring severe-weather season take down distribution lines across the Metroplex every year, and summer peak demand on the ERCOT grid has repeatedly produced conservation appeals.
Who buys it
Homeowners who cannot simply leave — small children, someone on medical equipment, a well pump, a home office, or livestock on the property.
The RS17A is installed across the Dallas–Fort Worth Metroplex by our own licensed crews — the cities we serve, what installation involves, and a free on-site survey before any number is put in writing.
Before you buy the RS17A
The questions that decide whether this is the right machine, answered properly rather than in a sentence on a product page.
- Will 17kW actually cover my house?Work it out against your own square footage, air conditioning and well pump before you buy.
- Is 17kW the right one of the three?The air-cooled range is 13kW, 17kW and 20kW. What separates them, and what each step costs.
- What can my city require?Less than it used to, and a third party can now do the inspection.
- Will it run my air conditioner?Two compressors starting on a Texas afternoon is the load that decides the answer.
- Load management, or just buy the bigger one?Shedding a circuit or two is often cheaper than stepping up a model.

Installed across Dallas–Fort Worth
The RS17A ships anywhere in the country. Installation is Dallas–Fort Worth only, carried out by our own licensed crews under TECL #40628 operating from Grand Prairie — because a generator is quoted against your gas meter, your panel and your city, which nobody can do from a warehouse. What installation actually involves.
- Generator installation in DentonDenton Municipal Electric, a community-owned utility, for most of the city, with CoServ Electric and Oncor at some addresses
- Generator installation in Cedar HillOncor or HILCO Electric Cooperative, depending on the address
- Generator installation in MidlothianHILCO Electric Cooperative serves the city per its own services page, with Oncor serving part of it — check your bill
