"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!"

"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."

"SUMMARY: HIGH QUALITY WORK WITH LARGE PRICETAG. Corley plumber arrived on time. Their plumber was polite and offered several options for the repair. The repair was completed correctly and in a timely manner. Work area was cleaned after plumbing work was completed. No problems with the repair since it was completed which was several years ago. In short, I would give them FIVE STARS FOR THE QUALITY OF THEIR WORK. I would hire them again in an EMERGENCY (which is why I hired them for this work; the usual plumbers I use were unavailable), but NOT for non-emergency work. My reason for not wanting to use them for routine work is that their prices were OUTRAGEOUS and I'm not a miser (this is why I removed one star in my rating). The few replacement parts needed would have been nominal cost at a plumbing supply store. That means their labor was $200+/hr for installing compression fit connections which is even easier and quicker than gluing PVC pipes together (no heavy lifting; nothing complicated; easy access to pipes). I've had other plumbing jobs that were too big for me to do. I've found competent plumbers that do a great job (quality like Corley's) for half the price if you are willing to wait a day or two. Lesson: Instant gratification has a high price tag. FYI: They will charge for the cost estimate if you don't have them do the repair."

Generator Install questions, answered by experts

It is safe to run a generator continuously, but you must follow safety protocols to ensure personal and home safety. Read the manufacturer’s instructions for specific recommendations, but the general recommendation is to turn generators off overnight or when you’re away from the house. Overworked generators can pose a fire hazard and if your generator is not in a well-ventilated area, running it continuously could lead to carbon monoxide poisoning.

It’s usually better to repair your generator if it isn’t working properly, as it will typically be much more affordable and should yield similar results. Generator repairs cost around $300 on average, while installing a new whole-house generator costs around $5,000 on average. The only exception is if you know your generator is reaching the end of its useful life, usually between 30 and 40 years. If you have an older generator, you could face multiple repairs in the coming years, which might mean that a full replacement will be more cost-effective over time.

A 10,000-watt generator can run a small to mid-sized central AC unit (typically up to 3 tons or 36,000 BTU) along with a few other appliances. However, larger AC units or additional loads will require a bigger generator. Consult a local generator installer to ensure you add the correct size generator to your home.

If you’re wondering if you can use your electric vehicle as a backup battery, it depends on whether your EV is compatible with bidirectional charging. This technology allows energy to flow both ways, enabling vehicle-to-home (V2H) backup power, vehicle-to-load (V2L) for appliances and camping, and vehicle-to-grid (V2G) to support the power grid. Compatible EVs convert stored DC energy into usable AC power, helping reduce energy costs and enhance grid stability while providing emergency backup power.

In most cases, there are no tax credits available for home generators. However, that’s a general statement that applies to federal tax credits, so you might have access to state or local tax incentives. You can check the Database of State Incentives for Renewables & Efficiency (DSIRE) for more information about your area. If you hire a reliable home generator installer, they should also know if there are any state or local perks you can use to reduce your installation costs, including tax breaks and rebates.
