Will use again if this ever happens again and we will be referring all of our customers, family and friends to. I'll take care of you guys!"

Customers say: Quick response

I like to think of my self as the best problem solver around. I'm sure there's a million ways to get the job done. But I only want to make sure its done right, The first time. \nI've been doing maintainece repairs for about 2 and half years now. I started off on my own path a couple of weeks ago and I've been off to what seems like a great start. I would be more than willing to see what kinda project you have to throw at this novice repair man.

"After scheduling, they contacted me to say there was a new opening for an earlier time, so we were able to get the project done even sooner, and they had better prices than the other people I had talked to. The technician was prompt, very nice, and did amazing work with the lighting fixtures. Everything came out leveled and centered. Would recommend to anyone!"

Generator Install FAQs, answered by experts

Whole-house generators can run continuously for extended periods, even for weeks at a time (around 400 to 500 hours), as long as they have a sufficient fuel supply. However, this type of extensive use will increase wear and tear and can shorten the generator's overall lifespan. During long periods of operation, it's important to check and refill the engine oil as needed, potentially as frequently as daily depending on the model. If your generator uses a fuel tank, ensure it is kept full to prevent unexpected shutdowns.

Sizing a generator is a careful process that requires calculating the electrical load of your entire house. You have to take into account every device you want to use and their wattage requirements, plus the wattage needed to start them, and look for a generator that can safely run all that at around 80% capacity.

In more practical terms, a small home can run on a 10,000-watt generator (and if you only want to power a few key appliances, much less than that). A mid-sized home may need something between 15,000 and 22,000 watts. Larger homes require 25,000 watts or more. 

Portable generators provide backup power for essential appliances during outages and are easy to relocate.

In some situations, yes. Never try to put biofuel into any home generator without checking the specifics first. If a generator has the ability to run on diesel, it can also run pure biofuel (the clear kind made from seed oils, for example). But if you are using biofuel made from animal fats or vegetable oils, the generator will need significant modifications before it can handle a sludgier type of biofuel.

Yes, installing a generator usually increases your property value because buyers are getting the added peace of mind knowing they’ll be able to maintain power through blackouts. In most cases, you should see close to a 100% return on investment (ROI). Keep in mind that home generators usually need a permanent foundation, and installing a concrete slab will likely raise your property taxes slightly.
