Our Services
Generator
InstallationNational Standby Repair sells and installs standby generators for homes, businesses, medical facilities, municipal properties, and other sites that cannot afford an extended loss of power. We carry equipment from Generac, Kohler, Cummins, Onan, Briggs & Stratton, WINCO, and other respected manufacturers. Our team evaluates your power requirements, recommends an appropriately sized unit, and coordinates the installation from the initial site visit through startup and testing. We can also connect commercial clients with qualified electricians, plumbers, and other subcontractors when needed.
Generator Repair and Maintenance
Our factory-trained technicians diagnose and repair residential and commercial systems from nearly every major manufacturer, including Generac, Kohler, Cummins, Onan, Briggs & Stratton, and WINCO. We also provide scheduled maintenance, warranty repairs, emergency service, and annual service contracts. Routine visits give our technicians a chance to inspect the engine, battery, transfer switch, controls, fluids, and other components before a minor issue turns into an expensive breakdown.
Load Bank
TestingCommercial diesel generators can sit unused for long stretches, which may allow carbon buildup, contaminated fuel, and reduced engine performance to go unnoticed. Load bank testing places the generator under a controlled electrical load so our technicians can evaluate its output, voltage, frequency, cooling system, and response under demand.
Fuel Polishing and
Fuel TestingWe also provide on-site fuel testing to identify water, sediment, bacteria, sludge, and other contaminants. When fuel quality falls below acceptable levels, National Standby Repair can provide filtration, scrubbing, and polishing services.
Generator
RentalsNational Standby Repair rents commercial generators ranging from 20 kW to 500 kW for short-term and long-term use.

Rated 4.6 by Our Customers
The service was the best from any of the providers we use on a regular basis. You showed real loyalty to the customers that have annual contracts with you. We called in the middle of our power outage in Connecticut and your very knowledgeable repair technician was at our home in two hours.
Peter F.New Canaan, CTThe power went out and the generator is working perfectly! It is so quiet I actually had to open the door to the patio to hear if it was on or whether it was just a quick outage and the regular power was back on. I am so happy we went with this one. Thank you so much for getting this perfect. I love it!
Vincent M.Bedford Hills, NYNational Standby Repair came to my rescue, not once but twice, during the superstorm. All I can say is thank you, thank you, thank you.
