Why You Should Install a Standby Generator

A standby generator is a smart choice for any savvy homeowner. In fact, it can provide you with many fantastic benefits.

  • Prevent food spoilage: When a power outage lasts for more than a few hours, the food in your fridge and freezer can spoil. Replacing all the food can be quite costly.
  • Deter theft: Power outages can cause an uptick in criminal activity. A standby generator will continue providing power to your home security system and lighting to deter property theft.
  • Safety lighting: When power outages happen at night, they can make it challenging to maneuver around your home safely. A generator will provide power for your lighting for optimal household safety.
  • Indoor comfort: A standby generator can easily power your heating or air conditioning system to keep your indoor environment comfortable.
  • Support critical appliances: Whether you have crucial medical devices or a sump pump to keep the Ohio River flood waters out, you can have peace of mind that a backup generator will keep them going even when your local power grid lets you down.
  • Automatic power restoration: A standby generator will have an automatic switch that will turn the unit on whenever it senses a drop in your city’s power supply. This will ensure a smooth transition for all your appliances without the need for you to physically turn on your generator.
  • Keep home businesses running: Whether you work from home or have a home-based business, having Wi-Fi and your electronics up and running is a must. A backup generator can power all these items to provide seamless services to all your customers.
  • Higher home value: Homebuyers know how beneficial standby generators are and will pay more for your home when you have one.

Top-Quality Generator Installations

A+ Derr is more than happy to install both standby and whole-home generators. Standby generators are a low-cost permanent option to provide power to select circuits in your home. This type of generator can’t supply adequate power to all your home’s systems. A whole-home generator is a costlier option that can provide enough power for all your electrical circuits during an outage.

We take the time to assess your home, electrical needs, and budget when determining the appropriate generator for your home. We provide generators for top-quality brands and even offer convenient financing. When you get a backup generator install by our electricians, you can rest assured your unit will operate perfectly. Our team works to take the guesswork and stress out of the generator-buying process for all our valued clients.

When to Replace a Generator

A+ Derr not only installs new generators but can also replace your outdated ones. Most whole-home generators have a workable lifespan of 10,000 to 30,000 hours. This roughly translates to about 20 to 40 years. If your generator is nearing the end of its usable lifespan, it’s time to think about a replacement.

If you experience any of the signs below, it’s time for an upgrade:

  • Frequent breakdowns
  • Inconsistent power supply
  • Outdated technology
  • Excessive fuel consumption
  • Struggles to meet your power needs
  • Fails self-testing
  • Expired warranty
  • Visible rust or damage
