"These pros were absolutely amazing.Talk about "an on-time" company....for the consultation.. So, this was the third company we asked for an estimate!! We were literally blown away when they came in between $800-almost $2000 less than any of the other estimates we got. Yes, we initially were a bit apprehensive, but their Master Electrician laid it out for us, same identical configuration from our electric panel in the unfinished room to the garage for the charger installation. Of, course, why would we not hire them? They had experience with these type of installations. Parker and his guys...were always available if we had "just another"question. Yes, we hired them...and they lived up to everything. Always on time....no hiccups, no changes, just a smooth---no stress---installation. We will always go back to them, if we need electric work to be done. Highly recommend this company. We are so thankful that they got in touch with us from my request at ANGI. Thank you Parker and TEAM!!"

"I’m a contractor that was doing a basement build for a customer and we needed to add a bunch of outlets, lights(dimmers), generator hook up and add a sub panel. The work was done on time and with a lot of care. Matt was great to work with and awesome communication throughout the project would highly recommend him for any project!!"

Generator Install questions, answered by experts

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.

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.

No, you should never plug a generator directly into a wall outlet in your house. This practice is extremely dangerous, often illegal, and can cause "back-feeding," where power from the generator flows back into utility lines, creating a life-threatening hazard for utility workers. It can also damage your home's electrical system, including appliances like pumps and HVAC fans. If the main power is restored while the generator is connected, it can destroy the generator and cause an electrical fire. To safely connect a generator, you must use a professionally installed transfer switch or an interlocking kit, which prevents back-feeding by disconnecting your home from the utility grid before the generator provides power.

In many cases, yes. There are models called dual-fuel generators and fuel switches, but only between certain types of fuel. For example, with the right setup you can convert a generator from natural gas to propane. Some allow switching between diesel and gasoline. There are even tri-fuel generators available in some cases, which adds a large layer of security if you are worried about fuel availability in times of crisis. Always check your generator capabilities and manual instructions before trying to switch fuels. Some generators can use another fuel but may need a fuel conversion kit to prep them first.

Many services include assembling the unit and securing it in the window. Confirm with your provider.
