When the power goes out, will you be prepared? While an occasional power outage lasting a few minutes is no big deal, if you face an extended outage lasting several hours or days, you’ll run into bigger problems. You also risk losing the food in your fridge and freezer. When your electrical power is compromised, a generator can provide temporary power until your services are restored. Black Diamond Plumbing & Mechanical can help you select and install a backup generator that will meet your demands to ensure you’re always prepared for any power outage.  

How Generators Work

When your power goes out, a generator will take over to provide power for a period of time. They use fuel to generate power and deliver that power to your home’s circuit breaker. Some start automatically, while others need a manual start-up. Not only is your power supply compromised during an outage, but your home’s water supply can be impaired with an outage as well.

Types of Generators

There are different types of generators: manual start, automatic start, and more. When choosing a generator, Black Diamond can help give you options based on your home, needs, budget, etc. Most installations won’t damage your home’s interior and can be operated and maintained entirely on the exterior of your home.

While we don’t offer portable generators, we do offer transfer switches for your portable generator. The types that we offer are:

Generator FAQs

Every six to 12 months or after an extended power outage. 

Most generators automatically run a test for a few minutes, running a full diagnostic on themselves. If there’s anything wrong with the unit, it will let you know. If there are other issues, a warning light will turn on.

This depends on your system. Most generators are designed to operate for eight, 12, or 24 hours. A handful can provide continuous operation for 72 hours or longer. Always check your manual before attempting to operate your machine for an extended period.

This is not a good idea. If you make a mistake in diagnosing the problem or completing the repair, you could void warranty coverage and create a fault in the system. It’s best to leave all repairs to a certified technician.
