FREQUENTLY ASKED QUESTIONS
What is an automatic standby generator?
It’s a back-up electrical system that constantly monitors the utility and starts automatically when a power outage occurs. When utility power returns, the generator automatically shuts itself off. Smaller Generac models are about as big as a central air conditioning unit, and operate on your normal LP or natural gas supply.
How large should my generator be?
Generac offers more models than any other manufacturer, which means there’s a generator that’s perfect for your home or business.
- To run essential items only, such as lights and receptacles, refrigerator, garage door opener, and security system, the likely choice will be one of our smaller models.
- Many small businesses and most homeowners choosing wholehouse coverage, including high-wattage items such as central A/C, electric water heater, dryer and stove, will probably need a generator in the 18 kW to 45 kW range.
- Very large homes and businesses with large compressors, refrigeration units, UPS systems, etc., may need one of our larger 60 kW to 150 kW models.
Your Generac installer will help you determine the generator that’s right for your needs.
How much do generators cost?
Automatic standby power has never been more convenient or more affordable. Models that will protect the essential circuits in your home start at less than $4,000, and units capable of covering all of the circuits in many homes are available for well under $10,000. Most businesses will need more power, but Generac generators often pay for themselves during a single outage. For more details check out our pricing page.
How is my generator installed?
Generac 7 kW to 150 kW standby generators offer the easiest and least expensive installation in the industry. All critical functions are pre-set at the factory, so the system can be installed by a qualified, licensed electrician. They are permanently installed outside and connected to your LP or natural gas supply. The contractor who installs your generator will be familiar with all relevant national, provincial and local codes and ordinances.
Are generators safe?
All Generac generators and transfer switches are UL and CUL Listed. That’s your assurance that they meet the highest safety and performance standards. In addition, our automatic standby generators produce a high quality, stable electrical output to ensure the safe operation of computers and other sensitive electronic equipment.
What do I do about maintenance?
Just as with your car or lawn mower, a generator needs periodic oil and filter changes. Most Generac owners take advantage of Generac’s extensive service organization for this routine maintenance.
Will my Generac generators meet strict noise regulations?
Our patented “Quiet-Test” low-speed exercise feature allows our generators to meet all known noise regulations. Quiet-Test reduces noise by about 50% during the generator’s weekly self-test cycle. That’s about as loud as a car idling in the driveway. When operating under load during an outage, sound levels are comparable to a central air conditioner. Quiet-Test is a standard feature on our 16 kW – 150 kW models.
