"Mr. Green TRULY puts the customer first! He installed a whole house generator for me last August and called to check on us 6 months later because bad weather is coming. Brought me a key and showed me (again) how to add oil. I had several estimates and he beat other prices by several thousand $ AND he installed a bigger generator! I will definitely hire him again and recommend him to every one!! 5 star service *****!!"

"5 stars! Mark Chapman with US Energy Solutions just installed a manual transfer switch box for my portable generator. The work was done professionally, on time, and very reasonably priced. Mark tested the install before he finished and it was perfect the first time. He was knowledgeable and experienced. My next electrical project will start with a call to Mark!"

"Bay and his crew were outstanding from start to finish. Bay communicated clearly, provided a fair and transparent quote, and showed real integrity throughout the project. Logan and Gino were equally impressive—an engaging, highly capable crew who made the work feel smooth and well organized. They were very flexible when my plans changed from replacing two light fixtures to installing ceiling fans with light dimmers. They also decommissioned and safely capped an existing light-fixture junction box, then installed a new electrical box, wiring, and mounting hardware for a pool table light fixture in a different location. The result looks great, allowed the pool table to be installed the next day and I’m very happy with the whole experience. I’ll absolutely be reaching out to Bay and his team for additional work already planned down the road. Highly recommend! Spot on experience."

"RAVE: Greg Avila with Avila Electric is an amazing electrician!! He just installed a Generac 22kw Generator to our home. Greg took care of scheduling the delivery of the generator to our house, obtaining required permit, scheduling with Duke Energy, and he does all the installation and wiring himself. Here is why the rave: - excellent communication - provides lots of options - reliable - trustworthy - very professional - super friendly and personable - attention to detail - honest and fair pricing - great listener, and provides viable solutions - answered all my questions and concerns Anyone else looking to have a permanent generator, portable generator connection, or any home electrical needs, I highly recommend Avila Electric!! For those wanting to know the process of having a permanent generator installed, please see below: 1. Propane (most difficult part) a. If you do not have propane, you will need to contact a propane company to rent propane tank(s) i. I chose Suburban Propane b. They will need to come out and see where the tank(s) will be placed, propane gas lines to be ran to the generator location c. You will need to contact 811 to mark, and survey the area (no cost) d. Schedule the installation of the propane tank(s). Currently, a lot of propane service companies are Two Weeks or more out for scheduling an appointment 2. Please contact Greg at Avila Electric for installation of our generator."

"I was very impressed with Keen and the crew. As a former remodel contractor (now retired) I know that contractors like Keen are a very rare breed. Honest, reliable and does what he says he will do when he says he will do it. He is the kind of contractor that everyone wants but rarely gets. Yes... I will have him back for a larger project. They started here installing 85' of underground wiring, installed a new panel,new breakers,outlets and a surge protector to cover the entire home and outbuilding. All in Tripple digit temperatures without any delays."

Generator Install questions, answered by experts

Homeowners can often access federal tax credits, such as the Investment Tax Credit (ITC), which covers a percentage of installation costs. Many states and utilities offer additional rebates, grants, or performance-based incentives. These programs can significantly lower your upfront investment. Check the Database of State Incentives for Renewables and Efficiency (DSIRE) or contact your local energy office for current offers.

It might seem counterintuitive, but installing a generator transfer switch will save you money in the long run. While you’ll have to pay between $400 and $2,500 to have the transfer switch installed, you’ll recoup that amount later on when you don’t have to pay for expensive repairs to your appliances, devices, and electrical system that may have burned out, overloaded, or stopped working due to a sudden loss of power or an incorrect hook up of a generator to your home. 

These advanced generators use a key fob or a smartphone app to remotely start, which is ideal for getting power back on immediately without venturing outside. This feature is more common on whole home generators, but you may be able to find it on large portable generators, too.

Generally, you’ll want to keep between 60 and 70 feet between the generator and the transfer switch. There are a few reasons for this, including:

  • The distance reduces the noise coming from the generator into your home.

  • It increases efficiency because you won’t have a voltage drop from this short of a distance.

  • Prevents carbon monoxide poisoning: keep at least 15 feet between your generator and an open window. 

Generators are safe to use as long as they are installed and operated correctly according to the manufacturer's recommendations. The most critical safety tips are to never use a portable or fuel-powered generator inside an enclosed space due to the risk of lethal carbon monoxide poisoning; always operate it outdoors where fumes can dissipate away from your home. Additionally, never attempt to connect a generator to your home’s electrical panel yourself—hire a professional to ensure the setup meets safety standards. Finally, avoid overloading the generator by not connecting more appliances than it is rated for, as this can damage your equipment or cause a fire.
