"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 *****!!"

"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

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.

Potential benefits of using a natural gas generator include reducing your carbon footprint, lower likelihood of carbon monoxide exposure, budget-friendly operating costs, and low-maintenance, continuous fuel supply. Some possible drawbacks, though, include higher initial installation costs, dependency on a natural gas supply, and installation complexity. Keep in mind that pros and cons will vary based on the type and brand of natural gas generator. 

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. 

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.

Setting up utilities on a vacant property usually takes at least a few months, or between 6 weeks to 16 weeks. This process requires working with the local planning and zoning department, hiring a building contractor or engineer to design the utility layout, securing permits, laying the lines, and connecting the utilities.
