Generators: Frequently Asked Questions
We’ve put together a few questions our customers seem to ask the most, and our answers. If you have a question not listed here, please give us a call and we’ll answer it for your personally. You can also ask your generator question through our Contact Us page.
Do I have to push a button to turn the generator on?
Generac generators with automatic transfer switches are just that, automatic. They monitor the electrical feed from the utility company, and when your home loses power, the backup generator will automatically turn on.
What do I have to do to make the generator work?
Once the generator is installed, there is nothing for the homeowner to do. Regular maintenance would include having the oil changed once a year by a certified technician.
Does it turn on automatically?
Yes. The transfer switch monitors power from the utility company and turns the backup generator on and back off again as needed.
How do I know the generator is working?
The generator runs a self-diagnostic test and runs briefly once a week for approximately ten minutes. This test will assure the Generac generator is ready when you need it. You tell us when you want the test to run, and we program it for you.
How much does a backup generator cost to operate?
Generac generators operate on either natural gas or propane. The cost is a function of how many home appliances, lights, and heating and/ or cooling equipment you have on as well as the cost of propane or gas at the time.
How long will it run?
As long as there is a fuel supply of natural gas or propane, a well-maintained backup generator will keep running. If the Generac generator is running on propane, with a 500-gallon tank, it should run 24 hours a day for over a week.
How loud are they?
Generac generators are very quiet. They are average rated at 66 decibels at three meters (about ten feet). That’s about the sound of the A/C running or a phone ringing.
What maintenance is required?
We recommend a service check up and oil change once a year. Schedule a maintenance check just like you would do with your air conditioner or furnace. A generator is an engine. It exercises once a week plus whatever power outages you experience.
Can a backup generator run the whole house?
It sure can. That’s what our experts help you figure out. We help determine what the right size generator is for your home and lifestyle. Our worst fear is you install a Generac generator that is too small to operate the equipment you want or need in an emergency.
Can I just run specific circuits?
Yes, you can select specific electrical circuits. If you are concerned operating only the furnace and refrigerator in a power outage, there is Generac standby generator designed to do just that.
Can I just have my air conditioner, refrigerator, and a few lights work if the power goes out?
You can install a generator to run just what you need or want; not too big and not too small.
What size generator would I need?
The size of the generator will be determined by our experts once they look over your home and meet with you. Every home and lifestyle is different. We don’t take a cookie-cutter approach. It’s your home and family, and we take that very seriously.
When I install a generator how long will it last?
According to the Generac design department, they are engineered for 40 years. It is not uncommon to expect 25 years of reliable service from a properly maintained generator.
Do you offer a maintenance agreement?
Yes, we do. The maintenance agreement includes two visits, and we perform all service and system testing.
If I buy a portable gas generator can I upgrade to a whole home generator?
Yes, it may require a new transfer switch. There may be other adjustments as technologies are developed.
