4 Benefits of Installing a Standby Generator

Power outages plague our area throughout the year due to our heavy rains and surprise winter storms. There are many benefits to installing a generator for your home. Just a few perks of these systems include:

  • Consistent power: When the power goes out, your lights, appliances, and devices will stay on.
  • Safety: With power always available to your home, you can keep the heat or AC running as needed.
  • Refrigeration: When the power goes out, your refrigerator and freezer will continue to run without issue.
  • Convenience: A generator will allow you to go on with life as if there’s no outage at all.

FAQs

Major brand-name generator companies state that their generators can run continuously for up to 500 hours without a problem. If refilled with fuel as needed, you can keep a generator running for weeks if necessary.

The size of your generator should be based on the size of your home and the wattage of your appliances. Generators range from 2,000 watts to 8,500 or even more. Our technicians can discuss your needs and provide a system that fits.

Whole-house generators are generally considered worth it for everyone. But they are especially useful for people in areas prone to extended outages and those who rely on electricity for major appliances and home systems like furnaces or water heaters.

Jake came and did my spring service yesterday. Their service is very professional, they are always out to get the best deals for anything I may need. I purchased new units from them a couple years ago, and the savings has been so noticeable.
