"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!!"

Generator Install questions, answered by experts

If your home already has a grinder pump and you’re still noticing issues (like frequently clogged toilets and sinks), it could be time to upgrade your grinder pump. Start by checking your existing horsepower. If there are four or fewer people living in your home, using a 1/2-horsepower grinder pump should be sufficient. Larger households should consider investing in a 1-horsepower grinder pump to maximize wastewater removal efforts.

As a safety measure, you should always turn off the main breaker while operating your generator’s backup breaker. In addition, you should also switch off all appliance breakers so you don't have a power surge when the main breaker turns back on. And finally, turning off the main breaker prevents back-feeding, which endangers utility workers with the risk of electrocution. Back-feeding could also destroy the electrical circuits of your neighbors if they use the same power network.

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.

Yes, natural gas generators can work without electricity. Natural gas generators are a common type of backup or whole-house generator that operates when the electrical grid isn’t working. The trick is using a transfer switch (which usually needs to be installed with the generator) that safely switches the home electrical system from the power grid to generator power when needed.

A home that is 2,500 square feet will likely need a 20kW to 25kW generator. Consult your local generator installer to confirm the generator size needed to power your home before purchasing a new one. Be sure to consider how much power your necessary devices need to run.
