Do I really need a standby generator?

You may be wondering if you even need a permanent standby generator for your home. There are certain situations where a standby generator should be a part of your home—including the need for powered medical equipment, if your neighborhood has regular prolonged outages from storms or weather, and how well your family members can tolerate disruptions to everyday life. Homes with elderly residents and children, in areas with regular outages, or regular severe weather outbreaks, should consider installing a permanent standby generator.

Can I run my home’s cooling system with a generator?

Depending on your generator, you should be able to run your central air unit. Look for a generator that includes an ACCM transfer switch. These switches will allow you to run a central air system that offers anything below a 4-ton rating.

What is the right size generator to be able to run my home’s electrical appliances during power outages?

If your home is between 1200 to 3000 sq. feet, a 5000-7000 watt generator will allow you to run most electrical appliances during power outages. These items may include a refrigerator, lights, TV, and water pumps.  Larger generators such as ones in the 10,000 to 15,000 watt area, can run quite a bit more and will allow you to live in the comfort you are accustomed to until your power is restored.

How do I know what size generator my home needs?

The best way to get the right generator is to have an electrician come out and complete and assessment. You will need to think about what electrical appliances you would need to run during an power outage or emergency. Talking with an electrician you will be able to work out what the right size system is for your home.

Do I need to start my generator frequently to make sure it works?

Like any equipment, it is a good idea to test your generator at least twice a year to make sure it is running correctly. A generator is there for emergency situations and you want to make sure it will work when those emergencies arise. You will also want to have your generator serviced by a professional at least once a year.

Can I control my generator when I am away from my home?

Sometimes emergencies occur when you are not home, even when you are out of town. In these situations it is nice to have remote access over your home’s electrical equipment. The good news is many companies are now creating generators that can be turned on and accessed remotely.  This allows you to turn your generator on no matter how far away you are.

How long does the average generator last?

When maintained correctly, a generator should last upwards of 20 years or be able to run for up to 12,000 hours in its lifetime.
