Service Agreement

Service agreements are 2-year agreements with The Generator Connection that are separate from the generator manufacturer’s warranty. It is beneficial to have one when it comes time for your regular yearly maintenance, non-warranty repairs, and emergency service. There is no cost to sign up, it is not a prepay plan, and you will only be billed after your scheduled work is completed.  Benefits include: Discounted labor rates and trip charges. A price lock on your maintenance and labor rates for 2 years. Priority proactive scheduling (we will contact you when your yearly maintenance is due). Access to our free 24/7 technical phone support. Priority emergency service call scheduling (agreement holding customers will be given priority over non-agreement customers if you call for emergency service). Signing a service agreement involves no risk, and we strongly encourage customers to do so.

Rental Generators

If your generator fails during a critical outage, we offer rental units with temporary hookups to keep your home or business running without interruption.

Replacement Parts and Accessories

We supply, install, and service a full range of genuine OEM replacement parts and accessories to keep your generator running efficiently.

Warranty

Each new generator purchase comes with a manufacturer’s warranty covering parts and labor costs for repairs related to premature part failure or manufacturing defects. Warranty coverage periods vary, and some manufacturers offer extended warranty options for purchase. Warranties do not cover routine maintenance, tune-ups, adjustments, batteries, or engine fluids (such as fuel, oil, and coolant) necessary to keep your generator running efficiently.  Warranties will not cover issues with accessories added to the generator, such as OnCue, heater kits, and e-stop buttons. Failures caused by an insufficient fuel supply, extreme weather, or natural events—including lightning strikes, ice/snow buildup, and rodent damage—may also not be covered. Please review the specific warranty documentation included with your purchase for complete coverage details.

Reduce Maintenance Costs with Remote Monitoring

Adding a remote standby generator monitoring system to your generator equipment helps reduces maintenance costs. A complete standby generator installation is a complicated system, both in terms of electrical and mechanical components. Common preventable, or easily corrected, problems include dead or weak batteries, low fuel level, block heater failure, leaving the generator in manual start or “not in auto” mode. All of these conditions can be effectively monitored using a remote monitoring system. 

Why Service Repair and Maintenance is Important 

Regular generator maintenance is essential, especially in New England where severe weather, unreliable utility power, and safety concerns make dependable backup power so important. Over time and through regular use, components such as batteries, oil, fluids, spark plugs, belts, and hoses naturally begin to wear and deteriorate. Valve clearances, ignition timing, and frequency settings may also require adjustment. 

At The Generator Connection, maintenance services are designed to keep your system running safely, efficiently, and reliably year-round. Regular inspections can help identify small issues before they become costly repairs, extend the life of your equipment, and give you peace of mind knowing your home or business is prepared when outages occur.

Warranty

The Generator Connection Inc. is an Authorized Warranty Center for the following brands: Kohler,Cummins, Winco, Generac, Briggs and Stratton

*The Warranty on any generator system depends on proper installation and maintenance.

FAQ’S

Is the KOHLER 10-Year Extended Warranty on top of the 5-year warranty (equal to 15 Yrs)?

NO. When purchasing the 10-year extended warranty, KOHLER is adding 5 more years from the installation date of the unit to equal 10 years of coverage.

Can I do my own maintenance on my Kohler generator?

The annual preventative maintenance must be performed by a KOHLER -authorized service technician.  WE (The Generator Connection) does not have to perform the maintenance, but it must be done annually by a KOHLER -authorized service technician, and you must show proof of work, or the warranty may be considered null and void due to customer neglect.

Are KOHLER Warranties Transferrable?

YES. A KOHLER warranty is transferrable to a new owner at the same location or the same owner at a new location if the generator set is installed by a Kohler-authorized dealer or service technician.
